Privacy Policy for Math Master
Last Updated & Effective Date: September 2026
Application: Math Master: Mental Math Speed Trainer (Package: com.msk.mathmaster)
Summary: Math Master is an arithmetic training and arcade game built to help users practice mental math. We prioritize your privacy: we do not collect, store, or transmit your personal identity, name, or email. Game progress is stored strictly on your local device. We use industry-standard advertising services (Unity LevelPlay / ironSource) to deliver ads that support free gameplay.
1. Information We Collect
Math Master does not operate external user login accounts or store personal user databases. We handle data in two ways:
- Local Gameplay Data: Your stars, unlocked campaign levels, equipped cosmetics (hats, weapons, outfits), high scores, and audio preferences are stored exclusively on your device's local storage. This data never leaves your device.
- Technical & Diagnostics Data: Non-personally identifiable diagnostic data (such as app version, crash diagnostics, and device model) may be automatically processed by Android runtime services to ensure compatibility and stability.
2. Third-Party Advertising & Ad Networks
To provide this game for free, Math Master integrates Unity LevelPlay (formerly ironSource Mediation) and third-party ad networks (such as Unity Ads). These networks may collect and process device-level identifiers to serve relevant ads, prevent fraudulent activity, and enforce ad frequency caps.
Information automatically processed by these ad partners may include:
- Google Advertising ID (AAID): A resettable, pseudonymized advertising identifier provided by Android.
- Device Hardware Information: Device make and model, operating system version, screen resolution, and system language.
- Network & Geolocation: Internet connection type (WiFi/Cellular), coarse approximate location (country/city level derived from IP address), and mobile carrier.
- Ad Interaction Data: Information regarding ad impressions, video completions, and clicks.
For more details on how our ad partners manage data, please review their official privacy policies:
3. Target Audience & Children's Privacy (13+)
Math Master is designed as a mental arithmetic speed trainer and brain workout intended for general audiences aged 13 and older. The app does not knowingly target, market to, or collect personal information from children under the age of 13. In accordance with Google Play's Families Policy and the Children's Online Privacy Protection Act (COPPA), our ad configurations explicitly declare child-directed settings as false (is_child_directed: false).
4. How You Can Control Your Ad Preferences (Opt-Out)
You have full control over personalized advertising directly from your Android device settings at any time:
- Go to your device Settings.
- Tap on Google → Ads.
- Select "Reset advertising ID" to generate a fresh identifier, or "Delete advertising ID" to stop receiving personalized ads completely.
5. Data Security & Retention
Because we do not transmit or store personal data on remote web servers, your game data remains under your control on your device. Uninstalling the game or clearing app storage will reset your local progress and preferences.
6. Policy Updates
We may update this Privacy Policy from time to time to reflect changes in legal requirements, SDK updates, or new game features. The updated date at the top of this document indicates when changes take effect.
