# Privacy Policy

**Last Updated: October 26, 2023**

ISOD Mobile ("the App") is designed with privacy as a core principle. This Privacy Policy explains how we handle information.

### 1. Data Collection
We do not collect, store, or transmit any personal information, usage data, or telemetry from the App. 

### 2. Third-Party Services
The App interacts directly with university systems (such as ISOD and USOS) to retrieve your schedule and grades. 
- **Authentication:** All authentication tokens (e.g., USOS OAuth tokens) are stored locally on your device and are never sent to any third-party servers other than the official university API endpoints.
- **Data Storage:** Your schedule, grades, and settings are stored locally on your device using a private database.

### 3. Permissions
The App may request the following permissions to function correctly:
- **Internet Access:** Required to fetch your schedule and announcements from university servers.
- **Notifications:** Used to alert you about upcoming classes or new grades. These are processed locally on your device.

### 4. Changes to This Policy
We may update our Privacy Policy from time to time. Since we do not collect any contact information, we encourage you to review this page periodically for any changes.

### 5. Contact
If you have any questions about this Privacy Policy, you can open an issue on the project's repository.
