Privacy Policy

Effective Date: November 2026

1. Local-First Learning Data

By default, GeoMastery stores your spaced-repetition progress, review streaks, and display preferences locally in your browser (localStorage) without requiring an account.

2. Optional Google Account Sync

If you choose to sign in with Google, we store your account identifier, email address, and spaced-repetition card state solely to synchronize your learning progress across your devices. We never sell or rent user data to third parties.

3. Geo-Personalization

Your browser language, timezone, or edge country code is read transiently to display localized greetings and relevant regional maps without collecting precise GPS coordinates.

4. Advertising & Cookies

Third-party advertising partners, including Google AdSense, may use cookies or web beacons to serve non-intrusive advertisements based on prior visits in accordance with regional consent choices (GDPR/CCPA). Users may manage personalized ad settings via Google Ad Settings.

5. Data Export & Deletion

You may export your complete learning history as JSON at any time from the account menu or delete local data by clearing site storage.
