Privacy Policy

Last updated: August 14, 2026

Domino Master (“we”, “our”, “the game”) is an HTML5 multiplayer domino game playable in a web browser and as a Telegram Mini App. This Privacy Policy explains what information we collect, how we use it, and how advertising partners such as Google may process data when ads are shown.

1. Information we collect

Gameplay data: room codes, scores, moves, and connection status needed to run multiplayer matches.
Display name: the name you type as a guest, or your Telegram profile name / photo when you open the game inside Telegram.
Technical data: IP address, browser type, device type, language, and approximate location derived from network signals.
Local storage: preferences such as sound settings and display name stored on your device.

2. How we use information

To operate, secure, and improve the game.
To reconnect you to your seat after a temporary disconnect.
To prevent cheating and abuse (for example, screen-protection features on the live table).
To show advertising (when enabled) and measure ad performance.

3. Analytics (Google Analytics)

We may use Google Analytics 4 to understand how the game is used (page views, traffic sources, device types, and aggregate gameplay events such as starting or finishing a match). Google may process technical data such as IP address (we request IP anonymization when Analytics is enabled), browser type, and approximate location.

4. Advertising and Google AdSense / H5 Games Ads

We may use Google AdSense and the Google H5 Games Ad Placement API to show interstitial or rewarded ads at natural breaks in gameplay (for example between rounds). Third parties, including Google, may use cookies, device identifiers, web beacons, or similar technologies to collect information and serve ads.

You can manage ad personalization through Google Ads Settings and industry tools such as aboutads.info.

5. Cookies and similar technologies

Cookies and local storage may be used for gameplay preferences, session continuity, fraud prevention, analytics, and advertising. By using the game you consent to this use where required by law.

6. Telegram

If you open Domino Master as a Telegram Mini App, Telegram may share limited profile data with us (such as user id and name) according to Telegram’s terms and the Mini App permissions you grant. We do not sell personal data.

7. Data retention

Live match data is kept in memory for the duration of the room and short reconnect windows. Device-side preferences remain until you clear site data.

8. Children’s privacy

The game is not directed to children under 13 (or the minimum digital consent age in your country). If you believe a child has provided personal data, contact us so we can delete it.

9. Your choices

Clear cookies / site data in your browser or Telegram WebView settings.
Leave a private room or close the Mini App at any time.
