Privacy Policy

Last updated: July 2026

Math On is a mental-maths game. This policy explains what data it handles. We keep it minimal: no names, addresses, or sensitive personal data are required to play.

What we store

Game progress — your scores, XP/level, coins, streak and achievements. Stored on your device, and (if you enable cloud sync) on our server, linked to an anonymous device id.
Account (optional) — if you sign in with Google or email, we store your account's unique id and email address (via Firebase Authentication) so your progress follows you across devices and appears on the global leaderboard.

We show ads through Google AdMob, which may collect device identifiers to serve and measure ads. See Google's advertising policy. You can remove ads with a one-time in-app purchase.

How we use it

Only to run the game: save your progress, sync across devices, show leaderboards, and display ads. We do not sell your data.

Deleting your data

Delete everything at any time in the app: Settings → Account → Delete account. This removes your account and all stored progress from our server immediately. See Delete your account for details, or email us.

Children

The game is suitable for all ages and does not knowingly collect personal information from children beyond the anonymous gameplay data above.
