Privacy Policy Template - Android Apps with Firebase Analytics + Crashlytics (Consent-Gated)
Android apps using only Firebase Analytics and Crashlytics behind an in-app consent switch (default off in EEA/UK/CH). No advertising SDKs, no advertising ID, no GameAnalytics, no in-app purchases.
1. Information We Collect
We do not require you to create an account or provide personal information to use the app. No name, email, phone, location, photos, microphone, contacts, purchases, or advertising ID is collected.
1.1 Stored only on your device (never uploaded)
- Game scores, best results and streaks.
- Progress, stars and boosters for the puzzle modes.
- Settings — including your analytics consent choice.
1.2 Collected by Firebase — only while consent is ON
Collection is disabled in the app until your Settings choice is applied. When it is ON, Firebase (Google LLC / Google Ireland Ltd) receives:
- Firebase Analytics events: gameplay events with game facts only (mode, level, score, duration, setting changes). No personal data.
- Automatic Firebase data: first_open/session data, app version, OS version, device model, language, approximate country/region derived from IP (the IP address is not stored in reports), and a random Firebase app-instance ID.
- Firebase Crashlytics reports: stack trace, device model, OS version, app version, device state at crash, and a Crashlytics installation ID.
The advertising ID is not collected: no IDFA and no ATT prompt on iOS, the AD_ID permission is removed on Android. No ad personalisation, no Google Signals, no cross-app or cross-site tracking. Nothing is sold.
2. Consent — How to Turn It Off
Settings has an "Analytics" switch that controls both analytics and crash reports. Default OFF in the EEA, UK and Switzerland (opt-in); default ON elsewhere (opt-out). You can change it at any time. When it is OFF, nothing is sent.
3. How We Use Information
- To keep the app stable (crash diagnostics).
- To improve gameplay balance, difficulty and content.
- To comply with legal obligations.
4. Legal Basis (GDPR)
- Consent (Art. 6(1)(a) GDPR): analytics and crash reports for users in the EEA, UK and Switzerland.
- Legitimate interests (Art. 6(1)(f) GDPR): keeping the app stable and improving it, elsewhere.
5. Data Retention
Event data is retained per the Firebase project setting of this app. Local game data is retained until you uninstall the app or clear its data.
6. Sharing and International Transfers
Data is shared only with Google LLC / Google Ireland Ltd as the service provider operating Firebase. Nothing is sold. Google may process data in the US and other countries; transfers rely on the Standard Contractual Clauses and, where applicable, the EU-US Data Privacy Framework.
7. Children's Privacy
The app is rated Everyone / 4+ and does not knowingly collect personal information from children under 13 (COPPA) or under 16 (GDPR). If you believe we have collected such information, contact us and we will delete it.
8. Your Rights and Deletion
- Access, deletion, objection, and withdrawing consent.
- Uninstalling the app removes all local data and the app-instance ID stops being used.

9. Changes to This Policy
We may update this Privacy Policy, for example when a new SDK or feature ships. Material changes are posted on this page with an updated "Last updated" date.
