Privacy Policy
Effective date: July 1, 2026 · Last updated: July 1, 2026
This Privacy Policy explains what information the Math Class mobile application (the "App"), operated by Stefan Cohn ("we", "us"), handles and how. The short version: we don't collect personal data ourselves beyond what the game needs to function — but the third-party ad and analytics services we use may collect device data, described below.
1. Data we store
We store the in-game data required to run your account:
- Account username;
- Match results and points scored;
- Skill rating (MMR) and per-topic performance statistics;
- Cosmetics owned and equipped, star coins, and XP.
We do not collect your real name, address, precise location, contacts, photos, or any biometric data.
2. Third-party services
The App uses Google AdMob (advertising) and Google Analytics (usage analytics). These services may collect information from your device, including:
- Device identifiers and advertising ID;
- IP address and approximate (coarse) location;
- App usage and interaction data.
Google's handling of this data is described in Google's Privacy Policy. You can reset or limit your advertising ID in your device settings.
3. Purchases
In-app purchases are processed by Apple (App Store) or Google (Google Play). We never see or store your payment information — billing runs entirely through the store you installed the App from.
4. Children
The App is intended for users 13 and older and is not directed to children under 13. We do not knowingly collect data from children under 13. Ads are served via AdMob under this posture.
5. Data retention & deletion
Account data is retained while your account is active. You can request deletion of your account and associated data at any time — see account & data deletion for exactly what gets removed and how to ask.
6. Changes
We may update this policy from time to time; changes are reflected in the "last updated" date above.
