GeoNibble

1. Summary

GeoNibble uses Firebase (Google) for authentication and cloud storage. If you choose to sign in with an account, your email and game progress are stored securely. Guest players have all data stored locally on their device only. The App displays ads to support free play, which are provided by Google AdMob.

2. Authentication & Account Data

If you create an account, you can sign in using:

• Sign in with Apple: Your Apple ID is used for authentication. I do not receive your password or email address directly. Apple handles the authentication securely.
• Email & Password: Your email and password are stored securely in Firebase Authentication. Your password is encrypted and I cannot access it.
• Guest Mode: No account is created. All data is stored locally on your device only.

3. Cloud Storage (Firebase)

If you have a signed-in account, the following data is stored in Firebase Firestore (Google's secure cloud database):

• Your daily quiz results and scores
• Your current and longest streak
• Your game progress across devices

This data is encrypted in transit and at rest. Only your authenticated user can access your data. You can delete your account and all associated data at any time from the Settings screen within the App.

4. Guest Data

If you play as a guest, all data is stored only on your device and is never transmitted to any server. Deleting the App removes all guest data.

5. Advertisements (Google AdMob)

The App displays ads provided by Google AdMob to support free play. To serve and measure ads, Google automatically collects:

• Advertising identifier (IDFA / IDFV)
• Device type, model and operating system version
• IP address (for approximate location)
• Ad interaction data (views, clicks, impressions)
• App usage signals for ad targeting and fraud prevention

Google's use of this data is governed by the Google Privacy Policy and the Google AdMob Partner Guidelines.

6. App Tracking Transparency (ATT)

On iOS 14.5 and later, the App will present Apple's App Tracking Transparency prompt before allowing AdMob to access your advertising identifier for personalised advertising. If you decline, ads may still be shown but will not be personalised. You can change this preference at any time in Settings → Privacy & Security → Tracking.

7. Remove Ads Subscription

The App offers optional auto-renewable subscriptions (weekly, monthly, and yearly) to remove advertisements. Subscriptions are processed entirely by Apple through the App Store. I do not receive, store, or process your payment details or billing information. Subscription management is handled through your Apple ID account settings.

8. Account Deletion

You can delete your account at any time from the Settings screen within the App. This will permanently delete all your data stored in Firebase, including your quiz results, scores, and streak information. This action cannot be undone. If you are a guest, your data is stored locally and will be deleted when you uninstall the App.

9. Daily Notifications

The App can send optional daily reminder notifications (default time: 8:00 AM) to encourage you to play. You must grant permission for notifications via the iOS notification prompt. You can disable this at any time in Settings → Notifications within the App.
