Domino Masters — Privacy Policy

Last updated: October 3, 2026

This policy explains what data the mobile game Domino Masters collects, why, and what choices you have. It covers the game on Google Play (“Dominoes: 4 players. Offline”) and on the App Store (“Dominoes: 4 Players”).

The game is developed by BlitzPlay Games (“we”, “us”). Questions and requests: privacy@blitzplay.games.

1. Data we collect

  • Game account: a random identifier created on your device for your guest account, the nickname and avatar you choose, and — if you sign in — your Google Play Games player ID (Android) or Game Center player ID (iOS). We do not receive your email address, real name or contacts from these services.
  • Gameplay data: matches played and their results, scores, league points, season experience, achievements, items you own (avatars, tile skins, tables, boxes) and club membership.
  • Purchase data: the product ID, transaction ID and purchase receipt, which our server checks with Google Play or the App Store before granting the purchase. Payments are processed by Google or Apple; we never receive your card details.
  • Device and technical data: device model, operating system and version, language, app version, the IP address of requests to our server, crash reports and diagnostic logs.
  • Advertising data: the advertising identifier (Android Advertising ID; on iOS the IDFA only if you allow tracking) and data about ads shown, processed by Google AdMob.
  • Usage analytics: in-game events such as match start and end and screens visited, processed by Google Firebase Analytics.

2. How we use it

  • To run the game, save your progress and restore it on another device.
  • To run the league, seasons, the battle pass and leaderboards.
  • To verify purchases, deliver what you bought and prevent fraud.
  • To show ads and reward videos and to measure them.
  • To find and fix crashes and improve the game.
  • To answer your support and privacy requests.

We do not sell your personal data.

3. Services that process data for us

  • Google AdMob and the Google User Messaging Platform — ads and consent (policies.google.com/privacy).
  • Google Firebase Analytics and Firebase Crashlytics — usage analytics and crash reports (firebase.google.com/support/privacy).
  • Google Play Games Services and Google Play Billing — sign-in and purchases on Android (policies.google.com/privacy).
  • Apple Game Center and the App Store — sign-in and purchases on iOS (apple.com/legal/privacy).
  • Our game server, which stores accounts and progress, runs at Hetzner Online in Helsinki, Finland (European Union).

4. Consent and ad choices

In the European Economic Area, the United Kingdom and Switzerland, the game asks for your consent to personalized ads on first launch. You can change your choice at any time in Settings → “Ad privacy choices”.

On iOS the advertising identifier is used only if you allow tracking when the system asks; otherwise ads are not personalized. On Android you can reset or delete the advertising ID in your device settings.

The “Remove Ads” purchase turns off ads between matches. Reward videos stay available and are always your choice.

5. Retention and deletion

We keep your account and game data while your account exists. You can delete them in the game at any time: Settings → “Delete account and data”. The account and everything stored on our server are erased immediately; this cannot be undone.

You can also ask us to delete your data by writing to privacy@blitzplay.games with your nickname. Server logs are kept only as long as needed for security and troubleshooting. Records of purchases may be kept as long as required by law.

6. Children

Domino Masters is a general-audience game and is not directed at children under 13. We do not knowingly collect personal data from children under 13. If you believe a child has provided us data, contact privacy@blitzplay.games and we will delete it.

7. Your rights

Depending on where you live (for example under the GDPR or the CCPA), you may have the right to access, correct, delete or export your personal data, to object to or restrict its processing, and to withdraw consent. To exercise these rights, write to privacy@blitzplay.games. You may also complain to your local data protection authority.

8. Security and transfers

Data between the game and our server is sent over encrypted HTTPS connections, and access to the server is restricted. The services listed above may process data in other countries under their own safeguards.

9. Changes

We may update this policy when the game changes. The date at the top shows the latest version.
