Privacy

The extension is designed with user privacy as a priority:

1. Local storage only: All user settings (API key, model preferences) are stored locally in Chrome’s extension storage. No user data is stored on external servers.

2. User-initiated requests only: The extension only sends data to OpenRouter when you explicitly click the trigger button. There is no background data collection.

3. Minimal data transmission: Only the selected text and surrounding context are sent to OpenRouter. No other page content, URLs, or metadata are transmitted.

4. No analytics: The extension does not include any analytics, tracking, or telemetry code.

5. Third-party data handling: Text sent to OpenRouter is subject to OpenRouter’s privacy policy and terms of service. Review their policies at https://openrouter.ai/privacy.
