Privacy Policy
This Privacy Policy explains how Mahjong Brain Training handles information when you use the Android app.
Mahjong Brain Training is a puzzle entertainment game. It is designed for fun, relaxation and cognitive-style challenge; it does not provide medical, psychological or professional training advice.
Information we may process
The app may process limited app-related information needed to operate, improve, protect and monetize the app, including:
- game progress, levels, scores, hints, shuffles, lives, rewards, settings and preferences;
- device and app information such as app version, device model, operating system version, language/region settings and performance data;
- crash logs, diagnostics and technical error information used to identify and fix bugs;
- advertising identifiers, ad request information, ad interaction information and consent signals where ads are shown;
- purchase or entitlement state where the app offers premium features, in-app products or restore-purchase flows;
- Google Play Games profile information such as player name, player icon and player ID where sign-in, achievements or leaderboards are enabled and used by the player.
Local data
Some progress, preferences, selected settings and app state may be stored locally on your device. Clearing app data, uninstalling the app or changing devices may delete local data unless a Google Play or platform feature preserves or restores it.
Third-party services
The app may use third-party services depending on the current app version and enabled features. These services process data according to their own policies and systems:
- Google Mobile Ads (AdMob) and Google User Messaging Platform: used for advertising, ad measurement, fraud prevention and consent management where ads are enabled.
- Firebase Analytics: used for aggregated app analytics and usage measurement where enabled.
- Firebase Crashlytics: used for crash reports, diagnostics and technical stability signals where enabled.
- Google Play Billing: used for purchases, premium unlocks, subscriptions if applicable, purchase validation and restore-purchase flows where purchases are offered.
- Google Play Games Services: used for achievements, leaderboards or player profile features where enabled.
How information is used
- to provide the app's core functionality and save local progress or preferences;
- to show ads, manage consent and prevent ad fraud where ads are enabled;
- to process purchases, premium state and restore-purchase flows where purchases are offered;
- to support achievements, leaderboards or player profile features where Google Play Games is enabled;
- to analyze crashes, diagnose problems, improve performance and protect app integrity;
- to comply with legal, platform, fraud-prevention and security requirements.
Data sharing
We do not sell your personal information. Data may be processed or shared with service providers such as Google services listed above, when required to operate ads, analytics, crash reporting, purchases, platform services, fraud prevention, legal compliance or app security.
Children
The app is not intended to knowingly collect personal information from children without appropriate consent where required by law. If you believe a child has provided personal information through the app, contact us so we can review the issue.
Security and retention
We use reasonable technical and organizational measures to protect information processed by the app. No system can be guaranteed to be completely secure. Local data may remain on your device until you delete it, clear app data or uninstall the app. Data processed by third-party services is retained according to those services' policies.

- You can uninstall the app to stop future app processing.
- You can clear local app data from Android settings.
- You can manage ad consent where a consent dialog or privacy options screen is available.
