This policy explains what data Chroma Blast (the "game") handles on Android and iOS. The game is published by Hamza Gassem ("we").
Summary
- No account, no sign-in. We never ask for your name, email, contacts, photos or location.
- Your progress and settings are stored only on your device.
- The game is free and shows ads served by Google AdMob. Ads may use your device's advertising ID, and only with your consent where the law requires it.
Data stored on your device
Scores, levels, streaks, settings (language, sound, vibration) and gameplay statistics used to adapt the difficulty are saved in the app's local storage. They never leave your device unless described below, and are deleted when you uninstall the game.
Advertising (Google AdMob)
The game uses Google AdMob to show banner, interstitial and optional rewarded ads. To serve and measure ads, Google may collect:
- the device advertising identifier (Android Advertising ID / Apple IDFA, only if you allow tracking on iOS);
- IP address, approximate location derived from it, device model, operating system and language;
- ad interactions (impressions, clicks) and app performance diagnostics.
When the game starts, users in the European Economic Area, the United Kingdom and Switzerland see a consent form (Google User Messaging Platform) and can accept or refuse personalised ads. You can change this choice later from the game's settings. On iOS, the game asks for permission to track (App Tracking Transparency). If you refuse, only non-personalised ads are shown.

Gameplay statistics
If you have given advertising consent, the game may send anonymous, aggregated gameplay and ad revenue events (for example level reached, session length, ad shown) to improve difficulty balance and ad pacing. These events do not include your name or contact details.
Purchases
The game has no in-app purchases. If we add one later, payment will be processed by Google Play or the Apple App Store, and we will never receive your payment details.
Children
The game is not directed at children under 13 and we do not knowingly collect personal data from them.
Your rights
You can reset the advertising ID or limit ad tracking in your device settings, withdraw ad consent in the game's settings, and delete all game data by uninstalling the game. For any request, contact us at contact.hamzello@gmail.com.
Changes
We will update this page if the game's data practices change.
