GradeWork Sync does not collect, store, or transmit any personal data to the developer.

Data Storage:
- Assignment data is stored locally in your browser using the browser's storage API
- No data is sent to any external servers owned by the developer

Google Calendar Integration:
- When you connect Google Calendar, the extension uses OAuth to access only your calendar
- Calendar access is between you and Google directly
- The developer never receives or has access to your Google account information

The extension requires the following permissions:
- Storage: To save your assignments and settings locally
- Notifications: To send reminder alerts
- Alarms: To schedule notifications
- Identity: To authenticate with Google Calendar (your account only)
