Information we collect
| Information | Purpose and destination |
|---|---|
| Email address, account ID, and Google profile name when provided | Account creation and authentication through Firebase Authentication. |
| Quiz scores by topic and visited chapter introductions | Save and sync learning progress through Google Cloud Firestore. A copy is also stored on the device. |
| Purchase and subscription status | Unlock Premium through Google Play Billing. We do not receive payment-card details. |
| Advertising ID, approximate location derived from IP, app/device information, and ad interactions | Serve and measure ads for non-Premium users through Google AdMob. |
| Optional feedback text | Respond to reports and improve the app through a Google Apps Script form. |
Google's User Messaging Platform stores applicable advertising consent choices on the device. French audio uses Android's on-device text-to-speech engine. We do not collect precise location, contacts, photos, files, or audio recordings.
How we use and share information
We use information only to authenticate users, save progress, provide purchases, display and measure ads, respond to feedback, and operate the service. We do not sell personal information. Information is handled by the Google services described above and may be disclosed when required by law.
Retention and deletion
Your account and synced progress remain until you delete the account. Delete it in the app under Settings → Delete account, or follow our web deletion instructions. Account deletion removes the Firebase account and synced progress. It does not cancel a Google Play subscription; cancel that separately in Google Play. Feedback may be retained to support follow-up. Google's retention rules apply to advertising data it holds.
Security
Data is transmitted using encrypted connections. Access to synced progress is restricted to the signed-in account. No storage method is perfectly secure.
Children
The app is not directed to children under 13. If you believe a child supplied personal information, contact us so we can delete it.
Your rights and policy changes
Depending on your location, you may have rights to access, correct, delete, export, or object to processing of your information. Contact us for assistance. Material policy changes will be reflected by an updated date and, when appropriate, an in-app notice.
This policy applies to the Android app with package name com.fg360.app.
