This Privacy Policy explains what data Mahjong: Legends of the Nile (“the Game”, “we”, “us”) collects, how it is used, and the choices you have. By installing or playing the Game you agree to this Policy.
1. Summary (the short version)
- The Game is free to play and supported entirely by advertising. There are no in-app purchases, ever.
- We collect the minimum data needed to run the Game, show ads, sync your progress to the cloud (if you sign in), and keep our leaderboards working.
- We do not sell your personal data.
- We do not show personalised ads to users under 13.
- You can play as a guest without signing in or sharing personal information.
2. Information we collect
2.1 Data you provide directly
- Display name you type in (if you change the default guest name) — stored on PlayFab and shown on the global leaderboard.
- Google account email + display name — only if you choose to Sign in with Google to back up your progress. This lets us link your save to your Google account so you can restore it on another device. We do not receive your password.
2.2 Data collected automatically
- Game progress and stats: levels completed, scores, time taken, power-ups used. Stored on your device and (if signed in) synced to PlayFab cloud save.
- Device information: model, manufacturer, operating system version, language, country, screen size. Used to optimise the Game and triage bugs.
- Crash reports and performance traces via Firebase Crashlytics and Firebase Analytics (Google LLC). Includes stack traces, device state at crash time, and basic interaction events (level started, level completed, ad shown). No message content or personally identifying free-text fields are recorded.
- Advertising identifier (AAID on Android, IDFA on iOS): used by Google AdMob to serve ads. You can reset or limit this in your device settings (Android: Settings → Privacy → Ads; iOS: Settings → Privacy → Tracking).
- IP address: processed by ad networks and Firebase for fraud prevention and approximate geolocation (country only). Not stored by us.
2.3 Data we do NOT collect
- We do not collect contacts, photos, microphone, camera, calendar, SMS, call history, precise location, biometrics, or any health data.
- We do not require any device permission to function (no permissions are requested at install).

4. Advertising and personalised ads
Ads in the Game are served by Google AdMob. AdMob may use your advertising identifier and approximate location (country) to show ads relevant to your interests.
Your choices:
- EU, UK, Switzerland (GDPR): on first launch you will see a Google-provided consent form. You can choose between personalised ads, non-personalised ads, or paying for an ad-free experience if offered. (We currently do not offer a paid ad-free option, so the choice is between personalised and non-personalised.) You can change your choice any time from the in-game Settings → Privacy Options link.
- California (CCPA): “Do Not Sell or Share My Personal Information” is honoured. Use the same Settings → Privacy Options link to opt out.
- All regions: disable ad personalisation at the OS level — Android: Settings → Google → Ads → “Delete advertising ID”. iOS: Settings → Privacy & Security → Tracking → toggle off “Allow Apps to Request to Track”.
We never show personalised ads to users under 13. If our age signal indicates the user is under 13 (declared age in app, or country with default restrictions), only non-personalised ads are served.
