15 Puzzle: Classic Number Game — Privacy Policy
Last updated: August 31, 2026
15 Puzzle: Classic Number Game ("the app") is developed by Jingalala Hu. This policy explains what data the app and its third-party services collect.
Data collected by the app itself
The app stores your best scores, total puzzles solved, and settings (theme, haptics) locally on your device only, via standard app storage. This data is never transmitted anywhere, is not linked to your identity, and is deleted if you uninstall the app or use the in-app "Reset progress" option.
Advertising (Google AdMob)
The app shows ads served by Google AdMob (banner, interstitial, and rewarded video). To do this, AdMob and its partners may collect and process:
- the advertising identifier (Android Advertising ID / iOS IDFA);
- device information (device type, OS version, general location from IP);
- ad interaction data (impressions, clicks, video completion).
This data is used to serve and measure ads, and — where you have not opted out — to personalize them. See Google's Privacy & Terms and How Google uses data in ads products.
Consent: for users in the EEA, UK, and Switzerland, the app uses Google's User Messaging Platform (UMP) to request consent before showing personalized ads, per Google's EU User Consent Policy. Users who decline personalization still see ads, served without personalization.
Children's privacy
This app is not directed at children under 13. If you believe a child has provided data through the app, contact jingalalahu4890@gmail.com and it will be removed.
Your choices
- Reset all locally-stored progress via Settings → Reset progress.
- Opt out of personalized advertising via your device's ad settings (Android: Settings → Google → Ads; iOS: Settings → Privacy → Tracking) or via the in-app consent form where shown.
- Uninstalling the app removes all local data immediately.
