Add currency symbol mapping in `GetCurrencySymbol()` in `internal/service/settings.go`\n3. Add currency option to currency selection in `templates/settings.html`\n4. Update exchange rate handling if using Fixer.io\n\n#### Adding a New Notification Method\n1. Create notification config model in `internal/models/settings.go`\n2. Create notification service in `internal/service/` (e.g., `pushover.go`)\n3. Add config save/get methods to `SettingsService`\n4. Add handlers in `internal/handlers/settings.go`\n5. Add UI in `templates/settings.html`\n6. Update subscription handler to send notifications\n7. Update renewal reminder scheduler in `cmd/server/main.go`\n\n### Environment Variables\n\n- `PORT` - Server port (default: 8080)\n- `DATABASE_PATH` - SQLite database path (default: ./data/subtrackr.db)\n- `GIN_MODE` - Gin mode: debug/release (default: debug)\n- `FIXER_API_KEY` - Fixer.io API key for currency conversion (optional)\n\n### Building and Running\n\n```bash\n# Development\ngo run cmd/server/main.go\n\n# Build\ngo build -o subtrackr cmd/server/main.go\n\n# Docker\ndocker-compose up -d --build\n```\n\n### Testing\n\n```bash\n# Run Go tests\ngo test ./...\n\n# Run E2E tests\nnpm test\n\n# Test API\n./test-api.sh\n```\n\n\n## Landing the Plane (Session Completion)\n\n**When ending a work session**, you MUST complete ALL steps below. Work is NOT complete until `git push` succeeds.\n\n**MANDATORY WORKFLOW:**\n\n1. **File issues for remaining work** - Create issues for anything that needs follow-up\n2. **Run quality gates** (if code changed) - Tests, linters, builds\n3. **Update issue status** - Close finished work, update in-progress items\n4. **PUSH TO REMOTE** - This is MANDATORY:\n ```bash\n git pull --rebase\n bd sync\n git push\n git status # MUST show \"up to date with origin\"\n ```\n5. **Clean up** - Clear stashes, prune remote branches\n6. **Verify** - All changes committed AND pushed\n7. **Hand off** - Provide context for next session\n\n**CRITICAL RULES:**\n- Work is NOT complete until `git push` succeeds\n- NEVER stop before pushing - that leaves work stranded locally\n- NEVER say \"ready to push when you are\" - YOU must push\n- If push fails, resolve and retry until it succeeds\n\n\n## Issue Tracking with bd (beads)\n\n**IMPORTANT**: This project uses **bd (beads)** for ALL issue tracking. Do NOT use markdown TODOs, task lists, or other tracking methods.\n\n### Why bd?\n\n- Dependency-aware: Track blockers and relationships between issues\n- Git-friendly: Auto-syncs to JSONL for version control\n- Agent-optimized: JSON output, ready work detection, discovered-from links\n- Prevents duplicate tracking systems and confusion\n\n### Quick Start\n\n**Check for ready work:**\n\n```bash\nbd ready --json\n```\n\n**Create new issues:**\n\n```bash\nbd create \"Issue title\" --description=\"Detailed context\" -t bug|feature|task -p 0-4 --json\nbd create \"Issue title\" --description=\"What this issue is about\" -p 1 --deps discovered-from:bd-123 --json\n```\n\n**Claim and update:**\n\n```bash\nbd update bd-42 --status in_progress --json\nbd update bd-42 --priority 1 --json\n```\n\n**Complete work:**\n\n```bash\nbd close bd-42 --reason \"Completed\" --json\n```\n\n### Issue Types\n\n- `bug` - Something broken\n- `feature` - New functionality\n- `task` - Work item (tests, docs, refactoring)\n- `epic` - Large feature with subtasks\n- `chore` - Maintenance (dependencies, tooling)\n\n### Priorities\n\n- `0` - Critical (security, data loss, broken builds)\n- `1` - High (major features, important bugs)\n- `2` - Medium (default, nice-to-have)\n- `3` - Low (polish, optimization)\n- `4` - Backlog (future ideas)\n\n### Workflow for AI Agents\n\n1. **Check ready work**: `bd ready` shows unblocked issues\n2. **Claim your task**: `bd update --status in_progress`\n3. **Work on it**: Implement, test, document\n4. **Discover new work?** Create linked issue:\n - `bd create \"Found bug\" --description=\"Details about what was found\" -p 1 --deps discovered-from:`\n5. **Complete**: `bd close --reason \"Done\"`\n\n### Auto-Sync\n\nbd automatically syncs with git:\n\n- Exports to `.beads/issues.jsonl` after changes (5s debounce)\n- Imports from JSONL when newer (e.g., after `git pull`)\n- No manual export/import needed!\n\n### Important Rules\n\n- ✅ Use bd for ALL task tracking\n- ✅ Always use `--json` flag for programmatic use\n- ✅ Link discovered work with `discovered-from` dependencies\n- ✅ Check `bd ready` before asking \"what should I work on?\"\n- ❌ Do NOT create markdown TODO lists\n- ❌ Do NOT use external issue trackers\n- ❌ Do NOT duplicate tracking systems\n\nFor more details, see README.md and docs/QUICKSTART.md.\n\n\n" }, { "path": "CLAUDE.md", "content": "# SubTrackr - Claude Code Instructions\n\n## Release Workflow\n\nThis project uses versioned branches for releases.

By contrast,\nour General Public Licenses are intended to guarantee your freedom to\nshare and change all versions of a program--to make sure it remains free\nsoftware for all its users.\n\n When we speak of free software, we are referring to freedom, not\nprice. Our General Public Licenses are designed to make sure that you\nhave the freedom to distribute copies of free software (and charge for\nthem if you wish), that you receive source code or can get it if you\nwant it, that you can change the software or use pieces of it in new\nfree programs, and that you know you can do these things.\n\n Developers that use our General Public Licenses protect your rights\nwith two steps: (1) assert copyright on the software, and (2) offer\nyou this License which gives you legal permission to copy, distribute\nand/or modify the software.\n\n A secondary benefit of defending all users' freedom is that\nimprovements made in alternate versions of the program, if they\nreceive widespread use, become available for other developers to\nincorporate. Many developers of free software are heartened and\nencouraged by the resulting cooperation. However, in the case of\nsoftware used on network servers, this result may fail to come about.\nThe GNU General Public License permits making a modified version and\nletting the public access it on a server without ever releasing its\nsource code to the public.\n\n The GNU Affero General Public License is designed specifically to\nensure that, in such cases, the modified source code becomes available\nto the community. It requires the operator of a network server to\nprovide the source code of the modified version running there to the\nusers of that server. Therefore, public use of a modified version, on\na publicly accessible server, gives the public access to the source\ncode of the modified version.\n\n An older license, called the Affero General Public License and\npublished by Affero, was designed to accomplish similar goals. This is\na different license, not a version of the Affero GPL, but Affero has\nreleased a new version of the Affero GPL which permits relicensing under\nthis license.\n\n The precise terms and conditions for copying, distribution and\nmodification follow.\n\n TERMS AND CONDITIONS\n\n 0. Definitions.\n\n \"This License\" refers to version 3 of the GNU Affero General Public License.\n\n \"Copyright\" also means copyright-like laws that apply to other kinds of\nworks, such as semiconductor masks.\n\n \"The Program\" refers to any copyrightable work licensed under this\nLicense. Each licensee is addressed as \"you\". \"Licensees\" and\n\"recipients\" may be individuals or organizations.\n\n To \"modify\" a work means to copy from or adapt all or part of the work\nin a fashion requiring copyright permission, other than the making of an\nexact copy. The resulting work is called a \"modified version\" of the\nearlier work or a work \"based on\" the earlier work.\n\n A \"covered work\" means either the unmodified Program or a work based\non the Program.\n\n To \"propagate\" a work means to do anything with it that, without\npermission, would make you directly or secondarily liable for\ninfringement under applicable copyright law, except executing it on a\ncomputer or modifying a private copy. Propagation includes copying,\ndistribution (with or without modification), making available to the\npublic, and in some countries other activities as well.\n\n To \"convey\" a work means any kind of propagation that enables other\nparties to make or receive copies. Mere interaction with a user through\na computer network, with no transfer of a copy, is not conveying.\n\n An interactive user interface displays \"Appropriate Legal Notices\"\nto the extent that it includes a convenient and prominently visible\nfeature that (1) displays an appropriate copyright notice, and (2)\ntells the user that there is no warranty for the work (except to the\nextent that warranties are provided), that licensees may convey the\nwork under this License, and how to view a copy of this License. If\nthe interface presents a list of user commands or options, such as a\nmenu, a prominent item in the list meets this criterion.\n\n 1. Source Code.\n\n The \"source code\" for a work means the preferred form of the work\nfor making modifications to it. \"Object code\" means any non-source\nform of a work.\n\n A \"Standard Interface\" means an interface that either is an official\nstandard defined by a recognized standards body, or, in the case of\ninterfaces specified for a particular programming language, one that\nis widely used among developers working in that language.\n\n The \"System Libraries\" of an executable work include anything, other\nthan the work as a whole, that (a) is included in the normal form of\npackaging a Major Component, but which is not part of that Major\nComponent, and (b) serves only to enable use of the work with that\nMajor Component, or to implement a Standard Interface for which an\nimplementation is available to the public in source code form. A\n\"Major Component\", in this context, means a major essential component\n(kernel, window system, and so on) of the specific operating system\n(if any) on which the executable work runs, or a compiler used to\nproduce the work, or an object code interpreter used to run it.\n\n The \"Corresponding Source\" for a work in object code form means all\nthe source code needed to generate, install, and (for an executable\nwork) run the object code and to modify the work, including scripts to\ncontrol those activities. However, it does not include the work's\nSystem Libraries, or general-purpose tools or generally available free\nprograms which are used unmodified in performing those activities but\nwhich are not part of the work. For example, Corresponding Source\nincludes interface definition files associated with source files for\nthe work, and the source code for shared libraries and dynamically\nlinked subprograms that the work is specifically designed to require,\nsuch as by intimate data communication or control flow between those\nsubprograms and other parts of the work.\n\n The Corresponding Source need not include anything that users\ncan regenerate automatically from other parts of the Corresponding\nSource.\n\n The Corresponding Source for a work in source code form is that\nsame work.\n\n 2. Basic Permissions.\n\n All rights granted under this License are granted for the term of\ncopyright on the Program, and are irrevocable provided the stated\nconditions are met. This License explicitly affirms your unlimited\npermission to run the unmodified Program. The output from running a\ncovered work is covered by this License only if the output, given its\ncontent, constitutes a covered work. This License acknowledges your\nrights of fair use or other equivalent, as provided by copyright law.\n\n You may make, run and propagate covered works that you do not\nconvey, without conditions so long as your license otherwise remains\nin force. You may convey covered works to others for the sole purpose\nof having them make modifications exclusively for you, or provide you\nwith facilities for running those works, provided that you comply with\nthe terms of this License in conveying all material for which you do\nnot control copyright. Those thus making or running the covered works\nfor you must do so exclusively on your behalf, under your direction\nand control, on terms that prohibit them from making any copies of\nyour copyrighted material outside their relationship with you.\n\n Conveying under any other circumstances is permitted solely under\nthe conditions stated below. Sublicensing is not allowed; section 10\nmakes it unnecessary.\n\n 3. Protecting Users' Legal Rights From Anti-Circumvention Law.\n\n No covered work shall be deemed part of an effective technological\nmeasure under any applicable law fulfilling obligations under article\n11 of the WIPO copyright treaty adopted on 20 December 1996, or\nsimilar laws prohibiting or restricting circumvention of such\nmeasures.\n\n When you convey a covered work, you waive any legal power to forbid\ncircumvention of technological measures to the extent such circumvention\nis effected by exercising rights under this License with respect to\nthe covered work, and you disclaim any intention to limit operation or\nmodification of the work as a means of enforcing, against the work's\nusers, your or third parties' legal rights to forbid circumvention of\ntechnological measures.\n\n 4. Conveying Verbatim Copies.\n\n You may convey verbatim copies of the Program's source code as you\nreceive it, in any medium, provided that you conspicuously and\nappropriately publish on each copy an appropriate copyright notice;\nkeep intact all notices stating that this License and any\nnon-permissive terms added in accord with section 7 apply to the code;\nkeep intact all notices of the absence of any warranty; and give all\nrecipients a copy of this License along with the Program.\n\n You may charge any price or no price for each copy that you convey,\nand you may offer support or warranty protection for a fee.\n\n 5. Conveying Modified Source Versions.\n\n You may convey a work based on the Program, or the modifications to\nproduce it from the Program, in the form of source code under the\nterms of section 4, provided that you also meet all of these conditions:\n\n a) The work must carry prominent notices stating that you modified\n it, and giving a relevant date.\n\n b) The work must carry prominent notices stating that it is\n released under this License and any conditions added under section\n 7. This requirement modifies the requirement in section 4 to\n \"keep intact all notices\".\n\n c) You must license the entire work, as a whole, under this\n License to anyone who comes into possession of a copy. This\n License will therefore apply, along with any applicable section 7\n additional terms, to the whole of the work, and all its parts,\n regardless of how they are packaged. This License gives no\n permission to license the work in any other way, but it does not\n invalidate such permission if you have separately received it.\n\n d) If the work has interactive user interfaces, each must display\n Appropriate Legal Notices; however, if the Program has interactive\n interfaces that do not display Appropriate Legal Notices, your\n work need not make them do so.\n\n A compilation of a covered work with other separate and independent\nworks, which are not by their nature extensions of the covered work,\nand which are not combined with it such as to form a larger program,\nin or on a volume of a storage or distribution medium, is called an\n\"aggregate\" if the compilation and its resulting copyright are not\nused to limit the access or legal rights of the compilation's users\nbeyond what the individual works permit. Inclusion of a covered work\nin an aggregate does not cause this License to apply to the other\nparts of the aggregate.\n\n 6. Conveying Non-Source Forms.\n\n You may convey a covered work in object code form under the terms\nof sections 4 and 5, provided that you also convey the\nmachine-readable Corresponding Source under the terms of this License,\nin one of these ways:\n\n a) Convey the object code in, or embodied in, a physical product\n (including a physical distribution medium), accompanied by the\n Corresponding Source fixed on a durable physical medium\n customarily used for software interchange.\n\n b) Convey the object code in, or embodied in, a physical product\n (including a physical distribution medium), accompanied by a\n written offer, valid for at least three years and valid for as\n long as you offer spare parts or customer support for that product\n model, to give anyone who possesses the object code either (1) a\n copy of the Corresponding Source for all the software in the\n product that is covered by this License, on a durable physical\n medium customarily used for software interchange, for a price no\n more than your reasonable cost of physically performing this\n conveying of source, or (2) access to copy the\n Corresponding Source from a network server at no charge.\n\n c) Convey individual copies of the object code with a copy of the\n written offer to provide the Corresponding Source. This\n alternative is allowed only occasionally and noncommercially, and\n only if you received the object code with such an offer, in accord\n with subsection 6b.\n\n d) Convey the object code by offering access from a designated\n place (gratis or for a charge), and offer equivalent access to the\n Corresponding Source in the same way through the same place at no\n further charge. You need not require recipients to copy the\n Corresponding Source along with the object code. If the place to\n copy the object code is a network server, the Corresponding Source\n may be on a different server (operated by you or a third party)\n that supports equivalent copying facilities, provided you maintain\n clear directions next to the object code saying where to find the\n Corresponding Source. Regardless of what server hosts the\n Corresponding Source, you remain obligated to ensure that it is\n available for as long as needed to satisfy these requirements.\n\n e) Convey the object code using peer-to-peer transmission, provided\n you inform other peers where the object code and Corresponding\n Source of the work are being offered to the general public at no\n charge under subsection 6d.\n\n A separable portion of the object code, whose source code is excluded\nfrom the Corresponding Source as a System Library, need not be\nincluded in conveying the object code work.\n\n A \"User Product\" is either (1) a \"consumer product\", which means any\ntangible personal property which is normally used for personal, family,\nor household purposes, or (2) anything designed or sold for incorporation\ninto a dwelling. In determining whether a product is a consumer product,\ndoubtful cases shall be resolved in favor of coverage. For a particular\nproduct received by a particular user, \"normally used\" refers to a\ntypical or common use of that class of product, regardless of the status\nof the particular user or of the way in which the particular user\nactually uses, or expects or is expected to use, the product. A product\nis a consumer product regardless of whether the product has substantial\ncommercial, industrial or non-consumer uses, unless such uses represent\nthe only significant mode of use of the product.\n\n \"Installation Information\" for a User Product means any methods,\nprocedures, authorization keys, or other information required to install\nand execute modified versions of a covered work in that User Product from\na modified version of its Corresponding Source. The information must\nsuffice to ensure that the continued functioning of the modified object\ncode is in no case prevented or interfered with solely because\nmodification has been made.\n\n If you convey an object code work under this section in, or with, or\nspecifically for use in, a User Product, and the conveying occurs as\npart of a transaction in which the right of possession and use of the\nUser Product is transferred to the recipient in perpetuity or for a\nfixed term (regardless of how the transaction is characterized), the\nCorresponding Source conveyed under this section must be accompanied\nby the Installation Information. But this requirement does not apply\nif neither you nor any third party retains the ability to install\nmodified object code on the User Product (for example, the work has\nbeen installed in ROM).\n\n The requirement to provide Installation Information does not include a\nrequirement to continue to provide support service, warranty, or updates\nfor a work that has been modified or installed by the recipient, or for\nthe User Product in which it has been modified or installed. Access to a\nnetwork may be denied when the modification itself materially and\nadversely affects the operation of the network or violates the rules and\nprotocols for communication across the network.\n\n Corresponding Source conveyed, and Installation Information provided,\nin accord with this section must be in a format that is publicly\ndocumented (and with an implementation available to the public in\nsource code form), and must require no special password or key for\nunpacking, reading or copying.\n\n 7. Additional Terms.\n\n \"Additional permissions\" are terms that supplement the terms of this\nLicense by making exceptions from one or more of its conditions.\nAdditional permissions that are applicable to the entire Program shall\nbe treated as though they were included in this License, to the extent\nthat they are valid under applicable law. If additional permissions\napply only to part of the Program, that part may be used separately\nunder those permissions, but the entire Program remains governed by\nthis License without regard to the additional permissions.\n\n When you convey a copy of a covered work, you may at your option\nremove any additional permissions from that copy, or from any part of\nit. (Additional permissions may be written to require their own\nremoval in certain cases when you modify the work.) You may place\nadditional permissions on material, added by you to a covered work,\nfor which you have or can give appropriate copyright permission.\n\n Notwithstanding any other provision of this License, for material you\nadd to a covered work, you may (if authorized by the copyright holders of\nthat material) supplement the terms of this License with terms:\n\n a) Disclaiming warranty or limiting liability differently from the\n terms of sections 15 and 16 of this License; or\n\n b) Requiring preservation of specified reasonable legal notices or\n author attributions in that material or in the Appropriate Legal\n Notices displayed by works containing it; or\n\n c) Prohibiting misrepresentation of the origin of that material, or\n requiring that modified versions of such material be marked in\n reasonable ways as different from the original version; or\n\n d) Limiting the use for publicity purposes of names of licensors or\n authors of the material; or\n\n e) Declining to grant rights under trademark law for use of some\n trade names, trademarks, or service marks; or\n\n f) Requiring indemnification of licensors and authors of that\n material by anyone who conveys the material (or modified versions of\n it) with contractual assumptions of liability to the recipient, for\n any liability that these contractual assumptions directly impose on\n those licensors and authors.\n\n All other non-permissive additional terms are considered \"further\nrestrictions\" within the meaning of section 10. If the Program as you\nreceived it, or any part of it, contains a notice stating that it is\ngoverned by this License along with a term that is a further\nrestriction, you may remove that term. If a license document contains\na further restriction but permits relicensing or conveying under this\nLicense, you may add to a covered work material governed by the terms\nof that license document, provided that the further restriction does\nnot survive such relicensing or conveying.\n\n If you add terms to a covered work in accord with this section, you\nmust place, in the relevant source files, a statement of the\nadditional terms that apply to those files, or a notice indicating\nwhere to find the applicable terms.\n\n Additional terms, permissive or non-permissive, may be stated in the\nform of a separately written license, or stated as exceptions;\nthe above requirements apply either way.\n\n 8. Termination.\n\n You may not propagate or modify a covered work except as expressly\nprovided under this License. Any attempt otherwise to propagate or\nmodify it is void, and will automatically terminate your rights under\nthis License (including any patent licenses granted under the third\nparagraph of section 11).\n\n However, if you cease all violation of this License, then your\nlicense from a particular copyright holder is reinstated (a)\nprovisionally, unless and until the copyright holder explicitly and\nfinally terminates your license, and (b) permanently, if the copyright\nholder fails to notify you of the violation by some reasonable means\nprior to 60 days after the cessation.\n\n Moreover, your license from a particular copyright holder is\nreinstated permanently if the copyright holder notifies you of the\nviolation by some reasonable means, this is the first time you have\nreceived notice of violation of this License (for any work) from that\ncopyright holder, and you cure the violation prior to 30 days after\nyour receipt of the notice.\n\n Termination of your rights under this section does not terminate the\nlicenses of parties who have received copies or rights from you under\nthis License. If your rights have been terminated and not permanently\nreinstated, you do not qualify to receive new licenses for the same\nmaterial under section 10.\n\n 9. Acceptance Not Required for Having Copies.\n\n You are not required to accept this License in order to receive or\nrun a copy of the Program. Ancillary propagation of a covered work\noccurring solely as a consequence of using peer-to-peer transmission\nto receive a copy likewise does not require acceptance. However,\nnothing other than this License grants you permission to propagate or\nmodify any covered work. These actions infringe copyright if you do\nnot accept this License. Therefore, by modifying or propagating a\ncovered work, you indicate your acceptance of this License to do so.\n\n 10. Automatic Licensing of Downstream Recipients.\n\n Each time you convey a covered work, the recipient automatically\nreceives a license from the original licensors, to run, modify and\npropagate that work, subject to this License. You are not responsible\nfor enforcing compliance by third parties with this License.\n\n An \"entity transaction\" is a transaction transferring control of an\norganization, or substantially all assets of one, or subdividing an\norganization, or merging organizations. If propagation of a covered\nwork results from an entity transaction, each party to that\ntransaction who receives a copy of the work also receives whatever\nlicenses to the work the party's predecessor in interest had or could\ngive under the previous paragraph, plus a right to possession of the\nCorresponding Source of the work from the predecessor in interest, if\nthe predecessor has it or can get it with reasonable efforts.\n\n You may not impose any further restrictions on the exercise of the\nrights granted or affirmed under this License. For example, you may\nnot impose a license fee, royalty, or other charge for exercise of\nrights granted under this License, and you may not initiate litigation\n(including a cross-claim or counterclaim in a lawsuit) alleging that\nany patent claim is infringed by making, using, selling, offering for\nsale, or importing the Program or any portion of it.\n\n 11. Patents.\n\n A \"contributor\" is a copyright holder who authorizes use under this\nLicense of the Program or a work on which the Program is based. The\nwork thus licensed is called the contributor's \"contributor version\".\n\n A contributor's \"essential patent claims\" are all patent claims\nowned or controlled by the contributor, whether already acquired or\nhereafter acquired, that would be infringed by some manner, permitted\nby this License, of making, using, or selling its contributor version,\nbut do not include claims that would be infringed only as a\nconsequence of further modification of the contributor version. For\npurposes of this definition, \"control\" includes the right to grant\npatent sublicenses in a manner consistent with the requirements of\nthis License.\n\n Each contributor grants you a non-exclusive, worldwide, royalty-free\npatent license under the contributor's essential patent claims, to\nmake, use, sell, offer for sale, import and otherwise run, modify and\npropagate the contents of its contributor version.\n\n In the following three paragraphs, a \"patent license\" is any express\nagreement or commitment, however denominated, not to enforce a patent\n(such as an express permission to practice a patent or covenant not to\nsue for patent infringement). To \"grant\" such a patent license to a\nparty means to make such an agreement or commitment not to enforce a\npatent against the party.\n\n If you convey a covered work, knowingly relying on a patent license,\nand the Corresponding Source of the work is not available for anyone\nto copy, free of charge and under the terms of this License, through a\npublicly available network server or other readily accessible means,\nthen you must either (1) cause the Corresponding Source to be so\navailable, or (2) arrange to deprive yourself of the benefit of the\npatent license for this particular work, or (3) arrange, in a manner\nconsistent with the requirements of this License, to extend the patent\nlicense to downstream recipients. \"Knowingly relying\" means you have\nactual knowledge that, but for the patent license, your conveying the\ncovered work in a country, or your recipient's use of the covered work\nin a country, would infringe one or more identifiable patents in that\ncountry that you have reason to believe are valid.\n\n If, pursuant to or in connection with a single transaction or\narrangement, you convey, or propagate by procuring conveyance of, a\ncovered work, and grant a patent license to some of the parties\nreceiving the covered work authorizing them to use, propagate, modify\nor convey a specific copy of the covered work, then the patent license\nyou grant is automatically extended to all recipients of the covered\nwork and works based on it.\n\n A patent license is \"discriminatory\" if it does not include within\nthe scope of its coverage, prohibits the exercise of, or is\nconditioned on the non-exercise of one or more of the rights that are\nspecifically granted under this License. You may not convey a covered\nwork if you are a party to an arrangement with a third party that is\nin the business of distributing software, under which you make payment\nto the third party based on the extent of your activity of conveying\nthe work, and under which the third party grants, to any of the\nparties who would receive the covered work from you, a discriminatory\npatent license (a) in connection with copies of the covered work\nconveyed by you (or copies made from those copies), or (b) primarily\nfor and in connection with specific products or compilations that\ncontain the covered work, unless you entered into that arrangement,\nor that patent license was granted, prior to 28 March 2007.\n\n Nothing in this License shall be construed as excluding or limiting\nany implied license or other defenses to infringement that may\notherwise be available to you under applicable patent law.\n\n 12. No Surrender of Others' Freedom.\n\n If conditions are imposed on you (whether by court order, agreement or\notherwise) that contradict the conditions of this License, they do not\nexcuse you from the conditions of this License. If you cannot convey a\ncovered work so as to satisfy simultaneously your obligations under this\nLicense and any other pertinent obligations, then as a consequence you may\nnot convey it at all. For example, if you agree to terms that obligate you\nto collect a royalty for further conveying from those to whom you convey\nthe Program, the only way you could satisfy both those terms and this\nLicense would be to refrain entirely from conveying the Program.\n\n 13. Remote Network Interaction; Use with the GNU General Public License.\n\n Notwithstanding any other provision of this License, if you modify the\nProgram, your modified version must prominently offer all users\ninteracting with it remotely through a computer network (if your version\nsupports such interaction) an opportunity to receive the Corresponding\nSource of your version by providing access to the Corresponding Source\nfrom a network server at no charge, through some standard or customary\nmeans of facilitating copying of software. This Corresponding Source\nshall include the Corresponding Source for any work covered by version 3\nof the GNU General Public License that is incorporated pursuant to the\nfollowing paragraph.\n\n Notwithstanding any other provision of this License, you have\npermission to link or combine any covered work with a work licensed\nunder version 3 of the GNU General Public License into a single\ncombined work, and to convey the resulting work. The terms of this\nLicense will continue to apply to the part which is the covered work,\nbut the work with which it is combined will remain governed by version\n3 of the GNU General Public License.\n\n 14. Revised Versions of this License.\n\n The Free Software Foundation may publish revised and/or new versions of\nthe GNU Affero General Public License from time to time. Such new versions\nwill be similar in spirit to the present version, but may differ in detail to\naddress new problems or concerns.\n\n Each version is given a distinguishing version number. If the\nProgram specifies that a certain numbered version of the GNU Affero General\nPublic License \"or any later version\" applies to it, you have the\noption of following the terms and conditions either of that numbered\nversion or of any later version published by the Free Software\nFoundation. If the Program does not specify a version number of the\nGNU Affero General Public License, you may choose any version ever published\nby the Free Software Foundation.\n\n If the Program specifies that a proxy can decide which future\nversions of the GNU Affero General Public License can be used, that proxy's\npublic statement of acceptance of a version permanently authorizes you\nto choose that version for the Program.\n\n Later license versions may give you additional or different\npermissions. However, no additional obligations are imposed on any\nauthor or copyright holder as a result of your choosing to follow a\nlater version.\n\n 15. Disclaimer of Warranty.\n\n THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY\nAPPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT\nHOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM \"AS IS\" WITHOUT WARRANTY\nOF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,\nTHE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR\nPURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM\nIS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF\nALL NECESSARY SERVICING, REPAIR OR CORRECTION.\n\n 16. Limitation of Liability.\n\n IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING\nWILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS\nTHE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY\nGENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE\nUSE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF\nDATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD\nPARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),\nEVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF\nSUCH DAMAGES.\n\n 17. Interpretation of Sections 15 and 16.\n\n If the disclaimer of warranty and limitation of liability provided\nabove cannot be given local legal effect according to their terms,\nreviewing courts shall apply local law that most closely approximates\nan absolute waiver of all civil liability in connection with the\nProgram, unless a warranty or assumption of liability accompanies a\ncopy of the Program in return for a fee.\n\n END OF TERMS AND CONDITIONS\n\n How to Apply These Terms to Your New Programs\n\n If you develop a new program, and you want it to be of the greatest\npossible use to the public, the best way to achieve this is to make it\nfree software which everyone can redistribute and change under these terms.\n\n To do so, attach the following notices to the program. It is safest\nto attach them to the start of each source file to most effectively\nstate the exclusion of warranty; and each file should have at least\nthe \"copyright\" line and a pointer to where the full notice is found.\n\n \n Copyright (C) \n\n This program is free software: you can redistribute it and/or modify\n it under the terms of the GNU Affero General Public License as published\n by the Free Software Foundation, either version 3 of the License, or\n (at your option) any later version.\n\n This program is distributed in the hope that it will be useful,\n but WITHOUT ANY WARRANTY; without even the implied warranty of\n MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the\n GNU Affero General Public License for more details.\n\n You should have received a copy of the GNU Affero General Public License\n along with this program. If not, see .\n\nAlso add information on how to contact you by electronic and paper mail.\n\n If your software can interact with users remotely through a computer\nnetwork, you should also make sure that it provides a way for users to\nget its source. For example, if your program is a web application, its\ninterface could display a \"Source\" link that leads users to an archive\nof the code. There are many ways you could offer source, and different\nsolutions will be better for different programs; see section 13 for the\nspecific requirements.\n\n You should also get your employer (if you work as a programmer) or school,\nif any, to sign a \"copyright disclaimer\" for the program, if necessary.\nFor more information on this, and how to apply and follow the GNU AGPL, see\n.\n" }, { "path": "MIGRATION_v0.3.0.md", "content": "# Migration Guide for SubTrackr v0.3.0\n\n## Overview\n\nSubTrackr v0.3.0 introduces a new dynamic categories system that replaces the previous hardcoded category strings with a flexible database-driven approach. This guide will help you migrate your existing installation to v0.3.0.\n\n## What's New\n\n- **Dynamic Categories**: Categories are now stored in a separate database table\n- **Category Management UI**: Add, edit, and delete categories from the Settings page\n- **Foreign Key Relationships**: Subscriptions now reference categories by ID\n- **Additional Schedule Options**: Support for Weekly and Daily subscription schedules\n\n## Migration Steps\n\n### 1. Backup Your Data\n\nBefore upgrading, make sure to backup your existing data:\n\n```bash\n# From the SubTrackr settings page, use the \"Create Backup\" button\n# Or use the API:\ncurl -H \"Authorization: Bearer YOUR_API_KEY\" \\\n http://localhost:8080/api/backup > subtrackr_backup.json\n```\n\n### 2. Update to v0.3.0\n\n```bash\n# Pull the latest changes\ngit pull origin v0.3.0\n\n# Or download the v0.3.0 release\n```\n\n### 3. Restart SubTrackr\n\nWhen you restart SubTrackr after updating:\n\n1. The database schema will automatically migrate\n2. Default categories will be created: Entertainment, Productivity, Storage, Software, Fitness, Education, Food, Travel, Business, Other\n3. Existing subscriptions will be mapped to the new category system\n\n### 4. Verify Migration\n\nAfter restarting:\n\n1. Check that all your subscriptions are still visible\n2. Verify that categories have been properly assigned\n3. Visit Settings → Categories to manage your categories\n\n## API Changes\n\nIf you're using the SubTrackr API, note these changes:\n\n### Creating/Updating Subscriptions\n\n**Before (v0.2.x):**\n```json\n{\n \"name\": \"Netflix\",\n \"cost\": 15.99,\n \"schedule\": \"Monthly\",\n \"status\": \"Active\",\n \"category\": \"Entertainment\"\n}\n```\n\n**After (v0.3.0):**\n```json\n{\n \"name\": \"Netflix\",\n \"cost\": 15.99,\n \"schedule\": \"Monthly\",\n \"status\": \"Active\",\n \"category_id\": 1\n}\n```\n\n### Getting Category IDs\n\nTo get the list of available categories and their IDs:\n\n```bash\ncurl http://localhost:8080/api/categories\n```\n\n## New Features\n\n### Schedule Options\n\nv0.3.0 adds support for Weekly and Daily schedules in addition to Monthly and Annual:\n\n- **Weekly**: Billed every 7 days\n- **Daily**: Billed every day\n\n### Category Management\n\n- Add custom categories for better organization\n- Edit category names\n- Delete unused categories (only if no subscriptions are using them)\n\n## Troubleshooting\n\n### Issue: Categories not showing after upgrade\n\n**Solution**: The categories should be automatically created on first run. If not, manually create them in Settings → Categories.\n\n### Issue: API calls failing with category errors\n\n**Solution**: Update your API calls to use `category_id` instead of `category`. Get the category IDs from the `/api/categories` endpoint.\n\n### Issue: Cannot delete a category\n\n**Solution**: Categories with active subscriptions cannot be deleted. First reassign or delete the subscriptions using that category.\n\n## Need Help?\n\nIf you encounter any issues during migration:\n\n1. Check the server logs for error messages\n2.

This must be backward-compatible with existing single-user installations.\n\n---\n\n## Confirmed Decisions\n\n| Decision | Choice | Rationale |\n|----------|--------|-----------|\n| Login toggle location | Settings page | All config in one place |\n| Default state | **OFF** | No breaking changes for existing/new installs |\n| Scope | Single-user auth | Self-hosted personal tool, no multi-user needed |\n\n---\n\n## Current State Analysis\n\n### What Exists\n- **No authentication**: App assumes single user, all routes public\n- **API Key auth**: Already exists for `/api/v1/*` routes (external access)\n- **Settings infrastructure**: Key-value store in SQLite, well-structured service layer\n- **Repository pattern**: Clean separation of concerns ready for extension\n\n### Key Files to Modify\n- `internal/handlers/settings.go` - Add login settings handlers\n- `internal/service/settings.go` - Add auth settings management\n- `internal/middleware/auth.go` - Extend with session-based auth\n- `internal/database/migrations.go` - Add user table migration\n- `internal/models/` - Add User model\n- `templates/settings.html` - Add login configuration section\n- `cmd/server/main.go` - Conditional middleware application\n\n---\n\n## Design Decisions\n\n### 1. Authentication Model: **Optional Single-User Auth**\n\n**Rationale**: SubTrackr is designed as a self-hosted personal tool. Multi-user support adds complexity without clear benefit.\n\n**Approach**:\n- Single admin account (username + password)\n- No user registration - admin sets credentials in settings\n- Session-based auth using secure cookies\n- Login can be enabled/disabled at any time\n\n### 2. Settings-Based Toggle\n\n**New Settings Keys**:\n```\nauth_enabled (bool) - Master toggle for login requirement\nauth_username (string) - Admin username\nauth_password_hash (string) - bcrypt hash of password\nauth_session_secret (string) - Secret for signing session cookies\nauth_reset_token (string) - Temporary password reset token (cleared after use)\nauth_reset_token_expiry (string) - Reset token expiration timestamp\n```\n\n### 3.

Add \"Security\" section to Settings page\n2. Toggle \"Require Login\" is **OFF by default**\n3. **Prerequisite check**: SMTP must be configured before login can be enabled\n4. When user enables toggle, form expands to set username/password\n5. After credentials saved, auth middleware activates\n6. User must login on next page navigation\n\n**SMTP Prerequisite Requirement**:\n- Login toggle is disabled/grayed out until SMTP is configured and tested\n- Shows message: \"Configure email settings above to enable password recovery\"\n- This ensures users always have a \"Forgot Password\" recovery path\n- Prevents lockout scenarios where user has no way to reset password\n\n**Benefits**:\n- All configuration in one place (no env vars required)\n- No separate setup wizard needed\n- Easy to disable if locked out (just toggle off)\n- Zero impact on existing installations until user opts in\n- **Password recovery always available** via email\n\n**Optional: Environment Variable Override** (for advanced users)\n\nFor Docker deployments where UI access isn't preferred:\n```\nAUTH_ENABLED=true|false # Override toggle (optional)\nAUTH_USERNAME=admin # Only used with AUTH_ENABLED=true\nAUTH_PASSWORD=securepass # Hashed on first server start\n```\nWhen env vars are set, Settings UI shows read-only status.\n\n---\n\n## Security Considerations\n\n### Password Storage\n- **bcrypt** with cost factor 12+\n- Never store plain text passwords\n- Environment variable passwords hashed on first server start\n\n### Session Management\n- **Secure cookies** with HttpOnly, SameSite=Strict\n- Session timeout: 24 hours (configurable)\n- Session secret auto-generated if not provided\n- CSRF protection via SameSite cookies + HTMX headers\n\n### Protected Routes (when auth enabled)\n```\nProtected:\n / - Dashboard\n /subscriptions - Subscription list\n /analytics - Analytics\n /calendar - Calendar\n /api/subscriptions/* - Internal API\n /api/settings/* - Settings API (except login)\n\nUnprotected:\n /login - Login page\n /api/auth/login - Login endpoint\n /api/v1/* - External API (uses API keys)\n /static/* - Static assets\n```\n\n### Lockout Recovery\n\n**Problem**: User forgets password, locked out of app\n\n**Solutions** (in order of preference):\n1. **Forgot Password email** (primary): Click \"Forgot Password\" on login page, receive reset link via SMTP\n2. **CLI reset command** (Docker-friendly): Run container with `--reset-password` flag\n3. **Environment override**: Set `AUTH_PASSWORD=newpassword` and restart\n4. **Database direct edit**: Delete `auth_password_hash` row from settings table\n5. **Data directory backup/restore**: Restore from backup without auth\n\n**Note**: SMTP is required before enabling login, ensuring option #1 is always available.\n\n---\n\n## CLI Password Reset Option\n\nFor Docker deployments where direct database access is inconvenient, provide a CLI flag to reset credentials.\n\n### Usage\n\n```bash\n# Reset password interactively (prompts for new password)\ndocker exec -it subtrackr /app/subtrackr --reset-password\n\n# Reset password non-interactively (for scripts)\ndocker exec -it subtrackr /app/subtrackr --reset-password --new-password \"newsecurepass\"\n\n# Disable authentication entirely (removes all auth settings)\ndocker exec -it subtrackr /app/subtrackr --disable-auth\n```\n\n### Docker Compose Example\n\n```yaml\n# One-time password reset (run separately, not in main compose)\ndocker compose run --rm subtrackr --reset-password\n```\n\n### Implementation Details\n\n**New CLI flags** (in `cmd/server/main.go`):\n```\n--reset-password Resets admin password (interactive or with --new-password)\n--new-password New password (used with --reset-password, skips prompt)\n--disable-auth Disables authentication, removes credentials\n```\n\n**Behavior**:\n1. Parse flags before starting HTTP server\n2. If reset flag present:\n - Connect to database\n - Prompt for new password (or use --new-password value)\n - Hash with bcrypt and update `auth_password_hash` setting\n - Print success message and exit (don't start server)\n3. If disable-auth flag present:\n - Delete all `auth_*` settings from database\n - Print confirmation and exit\n\n**Security considerations**:\n- `--new-password` in process list is visible; recommend interactive mode when possible\n- These flags only work with direct container access (not exposed via API)\n- Log password reset events for audit trail\n\n---\n\n## Database Changes\n\n### No New Tables Required\n\nUsing existing `settings` table for auth configuration:\n\n```sql\n-- New settings rows (only created when auth enabled)\nINSERT INTO settings (key, value) VALUES\n ('auth_enabled', 'true'),\n ('auth_username', 'admin'),\n ('auth_password_hash', '$2a$12$...'), -- bcrypt hash\n ('auth_session_secret', 'random-64-char-string');\n```\n\n**Why not a users table?**\n- Single-user design doesn't need it\n- Simpler migration path\n- Settings table already handles typed values well\n- Avoids foreign key complexity\n\n---\n\n## UI/UX Design\n\n### Settings Page Addition\n\n```\n┌─────────────────────────────────────────────────────────────┐\n│ Settings │\n├─────────────────────────────────────────────────────────────┤\n│ │\n│ ▼ Data Management │\n│ [Export] [Backup] [Clear Data] │\n│ │\n│ ▼ Email Notifications │\n│ [...existing SMTP settings...] │\n│ │\n│ ▼ Security ← NEW SECTION │\n│ ┌─────────────────────────────────────────────────────┐ │\n│ │ Require Login [Toggle OFF] │ │\n│ │ │ │\n│ │ ┌─ When enabled: ────────────────────────────────┐ │ │\n│ │ │ Username: [________________] │ │ │\n│ │ │ Password: [________________] │ │ │\n│ │ │ Confirm: [________________] │ │ │\n│ │ │ │ │ │\n│ │ │ Session Timeout: [24] hours │ │ │\n│ │ │ │ │ │\n│ │ │ [Save Credentials] │ │ │\n│ │ └─────────────────────────────────────────────────┘ │ │\n│ │ │ │\n│ │ ⓘ When login is required, you'll need to sign in │ │\n│ │ to access SubTrackr.

Add bcrypt dependency for password hashing\n2. Create auth settings methods in SettingsService\n3. Implement session management (cookie-based)\n4. Create login/logout handlers\n5. Create auth middleware that checks session\n\n### Phase 2: Settings UI\n6. Add Security section to settings.html\n7. Implement credential form with HTMX\n8. Add toggle state management\n9. Handle auth enable/disable flow\n\n### Phase 3: Login Page & Password Reset\n10. Create login.html template\n11. Implement login form with HTMX\n12. Add error handling (wrong password, etc.)\n13. Add redirect after login\n14. Create forgot-password.html template\n15. Implement password reset email sending (uses existing EmailService)\n16. Create reset-password.html template for setting new password\n17. Handle reset token generation, validation, and expiration\n\n### Phase 4: Route Protection\n18. Apply auth middleware conditionally\n19. Handle redirect to login for protected routes\n20. Ensure API keys still work independently\n\n### Phase 5: CLI Recovery Tools\n21. Add `--reset-password` flag to main.go\n22. Add `--new-password` flag for non-interactive reset\n23. Add `--disable-auth` flag to remove all auth settings\n24. Implement interactive password prompt (when no --new-password)\n\n### Phase 6: Testing & Edge Cases\n25. Test existing installations (no regression)\n26. Test enable/disable flow\n27. Test password reset flow via email\n28. Test CLI password reset (interactive and non-interactive)\n29. Test lockout recovery scenarios\n30. Test session timeout\n31. Update documentation\n\n---\n\n## Open Questions\n\n1. **Session storage**: In-memory (simple, lost on restart) vs SQLite (persistent)?\n - Recommendation: In-memory with \"Remember me\" extending cookie life\n\n2. **Multiple failed login attempts**: Rate limiting?\n - Recommendation: Simple delay after 5 failed attempts\n\n3. **Password requirements**: Minimum complexity?\n - Recommendation: Minimum 8 characters, no complexity rules (user's choice)\n\n4. **HTTPS requirement**: Should auth require HTTPS?\n - Recommendation: Warn but allow HTTP (self-hosted often behind reverse proxy)\n\n---\n\n## Risk Assessment\n\n| Risk | Likelihood | Impact | Mitigation |\n|------|------------|--------|------------|\n| User locked out | Medium | High | Env var override, clear docs |\n| Session hijacking | Low | Medium | Secure cookies, HTTPS warning |\n| Brute force attack | Low | Medium | Rate limiting after failures |\n| Regression in existing installs | Low | High | Comprehensive testing |\n| Complexity creep | Medium | Medium | Keep single-user, no roles |\n\n---\n\n## Success Criteria\n\n- [ ] Existing installations work unchanged after update\n- [ ] Auth can be enabled from Settings with zero config files\n- [ ] Login page is functional and styled consistently\n- [ ] Sessions persist across server restarts (Remember me)\n- [ ] Lockout recovery is documented and tested\n- [ ] API keys continue working independently\n- [ ] No performance impact when auth is disabled\n" }, { "path": "README.md", "content": "# SubTrackr\n\nA self-hosted subscription management application built with Go and HTMX.

The Fixer.io API key is completely optional for currency conversion features.\n\n### Option 1: Docker Compose (Recommended)\n\n1. **Create docker-compose.yml**:\n\n```yaml\nversion: '3.8'\n\nservices:\n subtrackr:\n image: ghcr.io/bscott/subtrackr:latest\n container_name: subtrackr\n ports:\n - \"8080:8080\"\n volumes:\n - ./data:/app/data\n environment:\n - GIN_MODE=release\n - DATABASE_PATH=/app/data/subtrackr.db\n # Optional: Enable automatic currency conversion (requires Fixer.io API key)\n # - FIXER_API_KEY=your_fixer_api_key_here\n restart: unless-stopped\n```\n\n2. **Start the container**:\n\n```bash\ndocker-compose up -d\n```\n\n3. **Access SubTrackr**: Open http://localhost:8080\n\n### Option 2: Docker Run\n\n```bash\ndocker run -d \\\n --name subtrackr \\\n -p 8080:8080 \\\n -v $(pwd)/data:/app/data \\\n -e GIN_MODE=release \\\n ghcr.io/bscott/subtrackr:latest\n\n# Optional: With currency conversion enabled\ndocker run -d \\\n --name subtrackr \\\n -p 8080:8080 \\\n -v $(pwd)/data:/app/data \\\n -e GIN_MODE=release \\\n -e FIXER_API_KEY=your_fixer_api_key_here \\\n ghcr.io/bscott/subtrackr:latest\n```\n\n### Option 3: Build from Source\n\n1. **Clone the repository**:\n```bash\ngit clone https://github.com/bscott/subtrackr.git\ncd subtrackr\n```\n\n2. **Build and run with Docker Compose**:\n```bash\ndocker-compose up -d --build\n```\n\n## 🐳 Deployment Guides\n\n### Portainer\n\n1. **Stack Deployment**:\n - Go to Stacks → Add Stack\n - Name: `subtrackr`\n - Paste the docker-compose.yml content\n - Deploy the stack\n\n2. **Environment Variables** (optional):\n ```\n PORT=8080\n DATABASE_PATH=/app/data/subtrackr.db\n GIN_MODE=release\n ```\n\n3. **Volumes**:\n - Create a volume named `subtrackr-data`\n - Mount to `/app/data` in the container\n\n### Proxmox LXC Container\n\n1. **Create LXC Container**:\n ```bash\n # Create container (Ubuntu 22.04)\n pct create 200 local:vztmpl/ubuntu-22.04-standard_22.04-1_amd64.tar.gz \\\n --hostname subtrackr \\\n --memory 512 \\\n --cores 1 \\\n --net0 name=eth0,bridge=vmbr0,ip=dhcp \\\n --storage local-lvm \\\n --rootfs local-lvm:8\n ```\n\n2. **Install Docker in LXC**:\n ```bash\n pct start 200\n pct enter 200\n \n # Update and install Docker\n apt update && apt upgrade -y\n curl -fsSL https://get.docker.com | sh\n ```\n\n3. **Deploy SubTrackr**:\n ```bash\n mkdir -p /opt/subtrackr\n cd /opt/subtrackr\n \n # Create docker-compose.yml\n nano docker-compose.yml\n # Paste the docker-compose content\n \n docker-compose up -d\n ```\n\n### Unraid\n\n1. **Community Applications**:\n - Search for \"SubTrackr\" in CA\n - Configure paths and ports\n - Apply\n\n2. **Manual Docker Template**:\n - Repository: `ghcr.io/bscott/subtrackr:latest`\n - Port: `8080:8080`\n - Path: `/app/data` → `/mnt/user/appdata/subtrackr`\n\n### Synology NAS\n\n1. **Using Docker Package**:\n - Open Docker package\n - Registry → Search \"subtrackr\"\n - Download latest image\n - Create container with port 8080 and volume mapping\n\n2. **Using Container Manager** (DSM 7.2+):\n - Project → Create\n - Upload docker-compose.yml\n - Build and run\n\n## 🔧 Configuration\n\n### Environment Variables\n\n| Variable | Description | Default |\n|----------|-------------|---------|\n| `PORT` | Server port | `8080` |\n| `DATABASE_PATH` | SQLite database file path | `./data/subtrackr.db` |\n| `GIN_MODE` | Gin framework mode (debug/release) | `debug` |\n| `FIXER_API_KEY` | Fixer.io API key for currency conversion (optional) | None |\n\n### Currency Conversion (Optional)\n\nSubTrackr supports automatic currency conversion using Fixer.io exchange rates:\n\n**Without API key:** (Fully functional)\n- Basic multi-currency support with display symbols\n- Manual currency selection per subscription\n- Subscriptions displayed in their original currency\n- No automatic conversion between currencies\n\n**With Fixer.io API key:**\n- Real-time exchange rates (cached for 24 hours)\n- Automatic conversion between any supported currencies\n- Display original amount + converted amount in your preferred currency\n\n**Setup:**\n1. Sign up for free at [Fixer.io](https://fixer.io/) (1000 requests/month)\n2. Get your API key from the dashboard\n3. Add `FIXER_API_KEY=your_key_here` to your environment variables\n4. Restart SubTrackr - currency conversion will be automatically enabled\n\n**Note:** The free Fixer.io plan only allows EUR as the base currency. SubTrackr automatically handles cross-rate calculations (e.g., USD→INR goes through EUR) so all currency conversions work correctly regardless of this limitation.\n\n**Supported currencies:** USD, EUR, GBP, JPY, RUB, SEK, PLN, INR, CHF, BRL, COP, BDT, CNY\n\n### Email Notifications (SMTP)\n\nConfigure SMTP settings in the web interface:\n\n1. Navigate to Settings → Email Notifications\n2. Enter your SMTP details:\n - **Gmail**: smtp.gmail.com:587\n - **Outlook**: smtp-mail.outlook.com:587\n - **Custom**: Your SMTP server details\n3. Test connection\n4. Enable renewal reminders\n\n### Pushover Notifications\n\nReceive push notifications on your mobile device via Pushover:\n\n1. **Get your Pushover credentials**:\n - Sign up at [pushover.net](https://pushover.net/) (free account)\n - Get your User Key from the dashboard\n - Create an application at [pushover.net/apps/build](https://pushover.net/apps/build) to get an Application Token\n\n2. **Configure in SubTrackr**:\n - Navigate to Settings → Pushover Notifications\n - Enter your User Key and Application Token\n - Click \"Test Connection\" to verify configuration\n - Save settings\n\n3. **Notification Types**:\n - **Renewal Reminders**: Get notified before subscriptions renew (uses the same reminder days setting as email)\n - **High Cost Alerts**: Receive alerts when adding expensive subscriptions (uses the same threshold as email alerts)\n\n**Note**: Pushover notifications work alongside email notifications. Both will be sent when enabled, giving you multiple ways to stay informed about your subscriptions.\n\n### Data Persistence\n\n**Important**: Always mount a volume to `/app/data` to persist your database!\n\n```yaml\nvolumes:\n - ./data:/app/data # Local directory\n # OR\n - subtrackr-data:/app/data # Named volume\n```\n\n## 🔐 Security Recommendations\n\n1. **Reverse Proxy**: Use Nginx/Traefik for HTTPS\n2. **Authentication**: Add basic auth or OAuth2 proxy\n3. **Network**: Don't expose port 8080 directly to internet\n4. **Backups**: Regular backups of the data directory\n\n### Nginx Reverse Proxy Example\n\n```nginx\nserver {\n server_name subtrackr.yourdomain.com;\n \n location / {\n proxy_pass http://localhost:8080;\n proxy_set_header Host $host;\n proxy_set_header X-Real-IP $remote_addr;\n proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;\n proxy_set_header X-Forwarded-Proto $scheme;\n }\n}\n```\n\n### Traefik Labels\n\n```yaml\nlabels:\n - \"traefik.enable=true\"\n - \"traefik.http.routers.subtrackr.rule=Host(`subtrackr.yourdomain.com`)\"\n - \"traefik.http.routers.subtrackr.entrypoints=websecure\"\n - \"traefik.http.routers.subtrackr.tls.certresolver=letsencrypt\"\n```\n\n## 📊 API Documentation\n\nSubTrackr provides a RESTful API for external integrations. All API endpoints require authentication using an API key.\n\n### Authentication\n\nCreate an API key from the Settings page in the web interface. Include the API key in your requests using one of these methods:\n\n```bash\n# Authorization header (recommended)\ncurl -H \"Authorization: Bearer sk_your_api_key_here\" https://your-domain.com/api/v1/subscriptions\n\n# X-API-Key header\ncurl -H \"X-API-Key: sk_your_api_key_here\" https://your-domain.com/api/v1/subscriptions\n```\n\n### API Endpoints\n\n#### Subscriptions\n\n| Method | Endpoint | Description |\n|--------|----------|-------------|\n| GET | `/api/v1/subscriptions` | List all subscriptions |\n| POST | `/api/v1/subscriptions` | Create a new subscription |\n| GET | `/api/v1/subscriptions/:id` | Get subscription details |\n| PUT | `/api/v1/subscriptions/:id` | Update subscription |\n| DELETE | `/api/v1/subscriptions/:id` | Delete subscription |\n\n#### Statistics & Export\n\n| Method | Endpoint | Description |\n|--------|----------|-------------|\n| GET | `/api/v1/stats` | Get subscription statistics |\n| GET | `/api/v1/export/csv` | Export subscriptions as CSV |\n| GET | `/api/v1/export/json` | Export subscriptions as JSON |\n\n### Example Requests\n\n#### List Subscriptions\n```bash\ncurl -H \"Authorization: Bearer sk_your_api_key_here\" \\\n https://your-domain.com/api/v1/subscriptions\n```\n\n#### Create Subscription\n```bash\ncurl -X POST \\\n -H \"Authorization: Bearer sk_your_api_key_here\" \\\n -H \"Content-Type: application/json\" \\\n -d '{\n \"name\": \"Netflix\",\n \"cost\": 15.99,\n \"schedule\": \"Monthly\",\n \"status\": \"Active\",\n \"category\": \"Entertainment\"\n }' \\\n https://your-domain.com/api/v1/subscriptions\n```\n\n#### Update Subscription\n```bash\ncurl -X PUT \\\n -H \"Authorization: Bearer sk_your_api_key_here\" \\\n -H \"Content-Type: application/json\" \\\n -d '{\n \"cost\": 17.99,\n \"status\": \"Active\"\n }' \\\n https://your-domain.com/api/v1/subscriptions/123\n```\n\n#### Get Statistics\n```bash\ncurl -H \"Authorization: Bearer sk_your_api_key_here\" \\\n https://your-domain.com/api/v1/stats\n```\n\nResponse:\n```json\n{\n \"total_count\": 15,\n \"active_count\": 12,\n \"total_cost\": 245.67,\n \"categories\": {\n \"Entertainment\": 45.99,\n \"Productivity\": 89.00,\n \"Storage\": 29.99\n }\n}\n```\n\n## 🤖 MCP Server (AI Integration)\n\nSubTrackr includes a [Model Context Protocol](https://modelcontextprotocol.io/) (MCP) server that allows AI assistants like Claude to read and manage your subscriptions via natural language.\n\n### Available Tools\n\n| Tool | Description |\n|------|-------------|\n| `list_subscriptions` | List all subscriptions |\n| `get_subscription` | Get a subscription by ID |\n| `create_subscription` | Create a new subscription |\n| `update_subscription` | Update an existing subscription |\n| `delete_subscription` | Delete a subscription |\n| `get_stats` | Get subscription statistics |\n\n### Setup\n\n#### Local Install\n\nBuild the MCP server binary:\n\n```bash\ngo build -o subtrackr-mcp ./cmd/mcp\n```\n\nAdd to your Claude Desktop (`claude_desktop_config.json`) or Claude Code (`.claude/settings.json`):\n\n```json\n{\n \"mcpServers\": {\n \"subtrackr\": {\n \"command\": \"/path/to/subtrackr-mcp\",\n \"env\": {\n \"DATABASE_PATH\": \"/path/to/subtrackr.db\"\n }\n }\n }\n}\n```\n\n#### Docker\n\nThe MCP binary is included in the Docker image. Configure your MCP client to exec into the container:\n\n```json\n{\n \"mcpServers\": {\n \"subtrackr\": {\n \"command\": \"docker\",\n \"args\": [\"exec\", \"-i\", \"subtrackr\", \"/app/subtrackr-mcp\"]\n }\n }\n}\n```\n\nThe MCP server shares the same SQLite database as the web server, so changes made through either interface are immediately visible in the other.\n\n## 🛠️ Development\n\n### Prerequisites\n\n- Go 1.21+\n- Docker (optional)\n\n### Local Development\n\n```bash\n# Install dependencies\ngo mod download\n\n# Run development server\ngo run cmd/server/main.go\n\n# Build binary\ngo build -o subtrackr cmd/server/main.go\n```\n\n### Building Docker Image\n\n```bash\n# Build for current platform\ndocker build -t subtrackr:latest .\n\n# Build multi-platform\ndocker buildx build --platform linux/amd64,linux/arm64 \\\n -t subtrackr:latest --push .\n```\n\n## 🤝 Contributing\n\nContributions are welcome!
