Privacy Policy
Last updated: May 6, 2026
1. The Short Version
Math Gym is built with your privacy in mind. We collect only what we need to make the app work well for you. We will never sell your data or track you across the internet. Your brain is here to learn, not to be a product.
2. What We Collect
When you sign in with Google, we receive your name, email address, and profile picture. Inside the app, we store compact progress, current coin balance, cosmetics, preferences, and account settings. Detailed practice attempts stay on your device unless you choose to share a note with us.
3. How We Use It
Your data is used to show personal progress summaries, sync across devices, and power non-comparative features (Math Gym does not run public leaderboards). That is the full list.
4. Where It Lives
Practice detail is stored locally on your device first. When signed in, compact account state syncs securely to Cloudflare's edge network. We use Google AdSense to display ads that help keep Math Gym free. Google may use cookies to serve ads based on your prior visits. You can opt out of personalised advertising at Google's Ads Settings. We do not use any other third-party analytics or tracking pixels.
5. Younger Users
Math Gym welcomes users from age 9 and up. We take extra care with younger users' data and follow applicable children's privacy rules. For users under 13, we encourage a parent or guardian to be involved.
6. You're in Control
You own your data. You can reset your progress anytime from Settings. You can delete your entire account, and we will remove everything we have. You can also use the app without signing in, and your data stays on your device only.
