# OptMeowt 🐾
OptMeowt ("Opt Me Out") is a browser extension for opting you out from web tracking. OptMeowt works by sending Global Privacy Control (GPC) signals to visited websites per the [GPC spec](https://privacycg.github.io/gpc-spec/) that we are developing [at the W3C](https://github.com/privacycg/gpc-spec). In addition, OptMeowt also opts you out from Google's Topics API.

## 3. How Does OptMeowt Work?
OptMeowt sends GPC signals to websites when you browse the web. Such signals must be respected for California consumers per the California Consumer Privacy Act (CCPA), [Regs Section 999.315(d)](https://oag.ca.gov/sites/all/files/agweb/pdfs/privacy/oal-sub-final-text-of-regs.pdf). The number of jurisdictions that require websites to respect GPC signals is increasing. Some websites also respect them even if they are not required to do so.
In detail, OptMeowt uses the following methods to opt you out:
1. The [GPC header and JS property](https://privacycg.github.io/gpc-spec/).
2. A `Permissions-Policy` header that opts sites out of Google's [Topics API](https://developer.mozilla.org/en-US/docs/Web/API/Topics_API) on Chromium-based browsers.
**Opting Out of the Topics API:** As all browser vendors are phasing out the use of third-party cookies. In this context Google introduced the [Topics API](https://developer.mozilla.org/en-US/docs/Web/API/Topics_API). The Topics API identifies users' general areas of interest which are then used for personalized advertising. These topics are generated through observing and recording a users' browsing activity. Websites will then receive access to these topics that are stored on users' browsers. To opt you out of the Topics API OptMeowt sends a `Permissions-Policy` header to all the sites you visit. This approach follows [Google's documentation](https://developer.chrome.com/en/docs/privacy-sandbox/topics/#site-opt-out) on how to opt a site out of the Topics API. Note that this functionality of OptMeowt is only available for Chromium browsers as other browsers do not implement the Topics API.
**Customizing which sites receive GPC signals:** For every site you visit OptMeowt will automatically add its domain to the `domain list`. Each newly added domain will receive GPC signals by default. However, you can exclude domains that should not receive GPC signals. This functionality is available on OptMeowt's popup window and settings page.
For a more in-depth look at how OptMeowt works, check out our [Beginners Guide to OptMeowt](https://docs.google.com/document/d/1H0sA6hK0Q0OLT4Tz_Yp-byHi0U4Ue5DO8k7K-NXnY2Q/edit?usp=sharing). (The document is up to date as of its date. Later changes to OptMeowt are not reflected.)
## 4. Installing OptMeowt from Source
Here are the instructions for installing OptMeowt from the source files in this repo.
### Chrome and Firefox
1. Clone this repo locally with:
```bash
git clone https://github.com/privacy-tech-lab/gpc-optmeowt.git
```
You can also download a zipped copy and unzip it.
2. Install [Node.js and npm](https://docs.npmjs.com/downloading-and-installing-node-js-and-npm).
3. From within your local `/gpc-optmeowt/` directory install OptMeowt's dependencies with:
```bash
npm ci
```
4. Build the project by running:
```bash
npm run build
```
This command will create a built for both Chrome and Firefox in `.../gpc-optmeowt/dist/chrome/` and `.../gpc-optmeowt/dist/firefox/`, respectively. `npm run build` will also create packaged versions of OptMeowt in `.../gpc-optmeowt/packages` for distribution on the Chrome Web Store and on Firefox Add-Ons.
### Chrome
5. In Chrome, navigate to the extensions page at `chrome://extensions/`.
6. Enable `Developer mode` with the slider on the top right corner of the extension page.
7. Click the `Load unpacked` button in the top left of the page.
8. Select the directory where you built OptMeowt, by default `/gpc-optmeowt/dist/chrome/` (the directory that contains the `manifest.json`).
### Firefox
5. In Firefox, navigate to the addons page with developer privileges at `about:debugging#/runtime/this-firefox`.
6. Under `Temporary extensions`, click `Load Temporary Add-on...`.
7. Select the manifest from the directory where you built OptMeowt, by default `/gpc-optmeowt/dist/firefox/manifest.json/`.
**Note**: OptMeowt is in active development and new features are being added, some of which may cause errors. You can always get the stable release version on the [Chrome Web Store](https://chrome.google.com/webstore/detail/optmeowt/hdbnkdbhglahihjdbodmfefogcjbpgbo) and on [Firefox Add-Ons](https://addons.mozilla.org/en-US/firefox/addon/optmeowt/). You can also disable sending GPC signals to a site in case OptMeowt causes it to break.
## 5. Installing OptMeowt for Developers
To build the development versions of OptMeowt follow the directions above but replace `npm run build` with:
```bash
npm run start
```
This command will run the npm script (referenced in `package.json`) that will call Webpack in development mode (Webpack settings are in `webpack.config.js`). `npm run start` will also initiate Webpack servers for both the Firefox and Chrome versions, which will listen for changes as you work and rebuild as necessary.
### 5.1 Webpack
Webpack will build the development versions of OptMeowt into the `dev` subdirectory instead of the `dist` subdirectory. The subdirectories for Chrome and Firefox are `dev/chrome` and `dev/firefox`, respectively.
Also, when you build for development, the development manifest (in `src/manifest-dev.json`) will be used instead of the distribution manifest (in `src/manifest-dist.json`). The development manifest contains an unsafe eval that we use for our source maps during development. The distribution manifest does not contain this eval. Webpack will select the correct manifest depending on whether you build for development or distribution.
To include new dependencies you can run:
```bash
npm install
```
Running this command instead of `npm ci` will include new dependencies in the `package-lock.json`, which is generated from the `package.json`.
### 5.2 Debugging
We like to use the [Debugger for Firefox](https://marketplace.visualstudio.com/items?itemName=firefox-devtools.vscode-firefox-debug) from within [Visual Studio Code](https://code.visualstudio.com/) when in development to help automating the development and build processes. The default behavior is `F5` to launch and load the extension in the browser. There is a similar extension that you can use for Chrome, [JavaScript Debugger](https://marketplace.visualstudio.com/items?itemName=ms-vscode.js-debug), which is already included in Visual Studio Code by default. Make sure to follow the online documentation on writing the correct `.vscode/launch.json` file, or other necessary settings files, in order to properly load OptMeowt with the debugger.
### 5.3 Developing on Windows
We have built most of our codebase in macOS, so path variables and similar code may cause the build to break in other OSs, in particular Windows. We recommend using macOS or installing a Linux OS if you will be working with the codebase in any significant manner.
## 6. Installing the OptMeowt PETS 2023 Version
The version of OptMeowt used in our 2023 PETS paper, [Usability and Enforceability of Global Privacy Control](https://sebastianzimmeck.de/zimmeckEtAlGPC2023.pdf), can be found in our [v3.0.0-paper release](https://github.com/privacy-tech-lab/gpc-optmeowt/releases/tag/v3.0.0-paper). To view the v3.0.0-paper code, you can [look at the repo here](https://github.com/privacy-tech-lab/gpc-optmeowt/tree/v3.0.0-paper). Instructions for building the extension locally are the same as stated above per our [Firefox instructions](https://github.com/privacy-tech-lab/gpc-optmeowt/tree/main#firefox). To activate Analysis mode in the v3.0.0-paper release press the `Protection Mode` label in the popup. In addition, Analysis mode requires other privacy extensions or browsers to be disabled. For further detailed information on how to use analysis mode, please refer to [our methodology](https://github.com/privacy-tech-lab/gpc-optmeowt/tree/v4.0.1/#4-analysis-mode-firefox-only).
Analysis mode used to be part of the OptMeowt extension but is now part of the [GPC Web Crawler](https://github.com/privacy-tech-lab/gpc-web-crawler), which you can use to analyze websites' GPC compliance at scale.
## 7. Testing
OptMeowt uses the [Mocha](https://mochajs.org/) framework as well as [Puppeteer](https://pptr.dev/) to execute its testing and continuous integration. The continuous integration is built into the OptMeowt repo with Github Actions. The [Actions tab](https://github.com/privacy-tech-lab/gpc-optmeowt/actions) shows all workflows and past unit test checks for previous PRs.
The test responsible for checking OptMeowt's ability to set the GPC signal can not be run with GitHub Actions. You can run it locally with:
```bash
npm test
```
Using Puppeteer this command will launch an automated headful browser on Chromium testing the Chrome GPC signal against the [GPC reference server](https://global-privacy-control.vercel.app/).
### 7.1 Running Automated Unit Tests
**Locally:**
You can run unit tests locally.
1. Clone this repo locally or download a zipped copy and unzip it.
2. Make sure npm is up to date by running `npm -v` to check the version and updating follow [the instructions on the npm site](https://docs.npmjs.com/try-the-latest-stable-version-of-npm), depending on your operating system.
3. Run tests with:
```bash
npm test
```
4. If Puppeteer is not installed, run:
```bash
npm install
```
**Continuous Integration:**
The continuous integration is built into the OptMeowt repo. Therefore, no changes to the extension environment are needed to run new tests.
### 7.2 Manual UI testing
The following procedure is for testing the OptMeowt extension UI, which cannot be automated. They are recommended to be performed manually as follows:
1. Download the version of the extension you want to test through `npm run start`. Then, download the unpacked dev version for your browser.
2. Navigate to a site with the well-known file, like <https://global-privacy-control.vercel.app/>
3. Click on the OptMeowt symbol in the top right of your browser.
- [ ] TEST 1: The symbol for the cat should be solid green.
- [ ] TEST 2: The URL of the website should be written under the "Protection Mode" banner.
- [ ] TEST 3: Global Privacy Control should be enabled.
- [ ] TEST 4: There should be a blue number detailing the number of domains receiving signals.
4. Click on the drop down for "3rd Party Domains".
- [ ] TEST 5: There should be sites that show up with Global Privacy Control switched on.
5. Navigate out of the "3rd Party Domains" drop down and click on the "Website Response" drop down
- [ ] TEST 6: There should be text showing that GPC Signals were accepted.
- [ ] TEST 7: Switch "Dark Mode" on and off and ensure the popup is correctly changing colors.
6. Navigate to the top of the popup and click on the "More" symbol (image: Sliders) to go to the Settings page.
7. In the main settings page, click on "Disable" and open the popup.
- [ ] TEST 8: The popup should be fully grayed out and showing the popup disabled.
8. In the website, move to the Domainlist page.
- [ ] TEST 9: There should be multiple domains showing in the Domainlist tab.
9. Go back to the main settings page and export Domainlist.
- [ ] TEST 10: Check the exported Domainlist and the Domainlist in the settings page to make sure the websites match up.
### 7.3 Creating a New Test
1. Navigate to `.../gpc-optmeowt/test/`. Then navigate to the folder in the test directory that corresponds to the tested function's location in the extension source code.
2. Create a new file in the matching folder. Name the file with the format `FUNCTION_NAME.test.js`.
For example, if testing a function named `sum` located in the folder `.../src/math`, create the test called `sum.test.js` in the folder `.../test/math`
3. Write test using [ECMAScript formatting](https://nodejs.org/api/esm.html).
## 8. OptMeowt's Permission Use
**Note**: We do not collect any data from you. Third parties will also not receive your data. The permissions OptMeowt is using are required for opting you out. To that end, OptMeowt uses the following permissions:
```json
"permissions": [
"declarativeNetRequest",
"webRequest",
"webRequestBlocking",
"webNavigation",
"<all_urls>",
"storage",
"activeTab",
"tabs",
"scripting"
]
```
- `declarativeNetRequest`: Allows OptMeowt to modify rules, allowing us to send the GPC header
- `webRequest`: Pauses outgoing HTTP requests to append opt out headers
- `webRequestBlocking`: Allows an extension to intercept and potentially block, modify, or redirect web requests before they are completed
- `webNavigation`: Similar to `webRequest`, allows OptMeowt to check when navigation requests are made to reset processes
- `<all_urls>`: Gives OptMeowt permission to access and interact with the content and data of any website visited by the browser
- `storage`: Allows OptMeowt to save your opt out preferences in your browser
- `activeTab`: Allows OptMeowt to set opt out signals on your active browser tab
- `tabs`: Allows OptMeowt to keep track of HTTP headers per tab to show you the opt out status of the current site in a popup
- `scripting`: Allows OptMeowt to declare content scripts and send the GPC DOM signal
## 9. OptMeowt's Architecture
Detailed information on OptMeowt's architecture is available in a [separate readme](https://github.com/privacy-tech-lab/gpc-optmeowt/blob/main/README_ARCHITECTURE.md).
**Note**: The architecture readme is only current as of its commit date.
## 10. Directories in this Repo
Here are the main directories in this repo:
- `src/`: Main contents of the OptMeowt browser extension.
- `src/assets`: Graphical elements of the extension, including logos and button images.
- `src/background`: Listeners for events and logic for sending privacy signals.
- `src/data`: Definitions of headers and privacy flags.
- `src/options`: UI elements and scripts for the supplemental options page.
- `src/popup`: UI elements and scripts for the popup inside the extensions bar.
- `src/theme`: Dark and light mode themes.
- `ui-mockup`: Contains PDF and XD files demonstrating the preliminary mockup of OptMeowt.
## 11. Third Party Libraries
OptMeowt uses various [third party libraries](https://github.com/privacy-tech-lab/gpc-optmeowt/blob/main/package.json). We thank the developers.
## 12. Developer Guide
If you have questions about OptMeowt's functionality or have found a bug, please check out our [FAQ \ Known quirks](https://github.com/privacy-tech-lab/gpc-optmeowt/wiki/FAQ-%5C-Known-quirks) page on the [Wiki](https://github.com/privacy-tech-lab/gpc-optmeowt/wiki). If you cannot find what you are looking for, feel free to open an issue, and we will address it.
**Note**: When viewing your browser's console on a site, a 404 error status code regarding the domain's GPC status file (`/.well-known/gpc.json`) may be shown. This behavior is normal and will occur (1) on domains that do not support GPC and (2) on domains that support GPC but do not host a `/.well-known/gpc.json` file.

complianceData.js
================================================================================
Fetches and processes GPC compliance data from state-specific hosted CSV files.
CSV URLs are read dynamically from states.json hosted on GitHub so they can be
updated server-side without requiring an extension update.
Compliance is determined by set membership and signal content:
- Domain in noncompliant_sites → 'non_compliant'
- Domain in all_sites, signals found → 'compliant'
- Domain in all_sites, all signals null (nothing to measure against) → 'no_signals'
- Domain in neither → 'no_data' (handled by caller)
- Network/server error → 'fetch_error' (handled by caller)
The 8 signal columns checked for null:
uspapi_before_gpc, uspapi_after_gpc,
usp_cookies_before_gpc, usp_cookies_after_gpc,
OptanonConsent_before_gpc, OptanonConsent_after_gpc,
gpp_before_gpc, gpp_after_gpc
When the all_sites CSV includes a `compliance_classification` column (per the
schema in gpc-web-ui at client/background_reading/COMPLIANCE_CLASSIFICATION_OVERVIEW.md
— https://github.com/privacy-tech-lab/gpc-web-ui/blob/master/client/background_reading/COMPLIANCE_CLASSIFICATION_OVERVIEW.md),
the parsed JSON object is attached to each domain entry as `classification` so
the popup can show per-family status (USPS, OptanonConsent, Well-known, GPP).
