Privacy Policy
Last updated: March 2026
The short version: SubSnitch does not collect, store, transmit, or share any of your data. Everything happens locally in your browser. Period.
Data Collection
SubSnitch does not collect any personal data, browsing history, form inputs, or any other information. We have no servers that receive data from the extension. There is no analytics, no telemetry, no tracking of any kind.
How SubSnitch Works
All page scanning and analysis happens entirely within your browser using local JavaScript. The extension:
- Reads the DOM of checkout pages to detect dark patterns
- Compares page elements against locally-stored pattern signatures
- Displays warnings directly in your browser
- Stores your preferences using
chrome.storage.localonly
No data ever leaves your browser. No network requests are made by the extension except to check for pattern database updates.
Local Storage
SubSnitch uses chrome.storage.local to store:
- Your extension preferences (e.g., notification settings)
- The dark pattern signature database (updated periodically)
- Sites you have explicitly whitelisted
This data never leaves your device and can be cleared at any time by uninstalling the extension.
Third-Party Services
SubSnitch does not integrate with any third-party analytics, advertising, or tracking services. We do not use Google Analytics, Facebook Pixel, or any similar tools — not even on this website.
Gmail Scanner
The optional Gmail scanning feature, if enabled, processes your emails entirely within your browser. Email content is never sent to our servers or any third party. The feature uses Google's OAuth solely to grant read access within your local browser session.
Transparency
SubSnitch is built with transparency as a core principle. We believe a tool designed to promote honesty should itself be honest.
Changes to This Policy
If we ever change this policy, we will update this page and the "last updated" date above. Given our commitment to zero data collection, we do not anticipate significant changes.
