- Engagement patterns: Weekly activity indicators
- General usage events: No personal information, just anonymized interaction patterns

What we DON'T track:
- Personal conversations or chat content
- Bookmark content or URLs you save
- Voice recordings or audio data
- Passwords, usernames, or authentication data
- Personal files or documents
- Your AI model preferences or configurations

2. Local Data Storage

The following data is stored locally in your browser and never transmitted to external servers:

• Bookmarks and web clippings: Content you save for learning
