1. **Recently Used Symbols**
- Which math symbols you click
- Timestamps of when symbols were clicked
- Limited to your last 20 used symbols
2. **Favorite Symbols**

- **Favorites**: Save and display your favorited symbols in the "Favorites" tab
- **Preferences**: Remember your settings between browser sessions
## Data Storage
**All data is stored locally on your device only.** We use Chrome's `chrome.storage.local` API, which stores data on your computer.
**We do NOT:**
- Send your data to external servers

- Collect any personally identifiable information (PII)
## Data Retention

## Third-Party Services

These permissions are used solely for the Extension's core functionality and do not enable any data collection beyond what is described above. The extension only accesses web pages when you explicitly click the extension icon, ensuring your privacy and security.
