This extension stores data locally in your browser only:
- Your API keys for AI providers (encrypted in browser storage)
- Your notes and editor content (in browser storage)
- Dark mode preference

No data is collected or sent to any servers except:
- Text selections are sent to your chosen AI provider (Gemini, OpenAI, or xAI) for explanations
- This happens only when you explicitly request an explanation

No analytics, tracking, or telemetry is included.
Your API keys never leave your browser except in authorized API calls to your chosen provider.
