Local-first

Chat history and configuration are stored locally in your browser, ensuring your data stays private.

AI Keys

Stored securely inchrome.storage.sync, encrypted at rest by Chrome.

Secure GitHub OAuth

Sign-in and star verification run via a Cloudflare Worker backend. Your GitHub access token remains on the server; the extension only stores a short-lived JWT. Tokens can be revoked server-side.

Minimal Permissions

Only the Chrome APIs necessary for core features are used.

No Analytics by Default

The extension does not collect analytics by default and is completely opt-in if added later.

Open Source

The full transparency of code and Worker implementation ensures you know exactly how your data is handled.
