Mopo MathSupportPrivacy中文Privacy Policy
Last updated October 4, 2026
Mopo Math ("the app") is made for children and their families, and it is built to work without knowing who you are. This page says what the app handles and why.
What stays on the device
Everything a child does in the app — answers, stars, levels, trophies, collected prizes, the days played and the settings — is saved on the device only. We do not receive it. Deleting the app deletes it.
No account, no ads, no tracking
There is no sign-up and nothing to fill in. The app shows no advertising, contains no analytics or advertising software, and does not track anyone across other apps or websites.
Purchases
The full version is sold as a monthly subscription or a one-time purchase, both handled by Apple; we never see payment details. A subscription renews until it is cancelled in the device's Settings. To know that the purchase was made and to restore it on your other devices, the app uses a purchase service. That service receives the App Store receipt, a random identifier created by the app, and basic technical details (app version, system version, device model, language and store country). It does not receive a name, an email address or anything a child types.
Game Center
If the device is signed in to Apple's Game Center, the app sends scores and earned achievements to Game Center so they appear on leaderboards. Game Center is run by Apple under Apple's privacy policy, and can be switched off in the device's Settings. The app works the same without it.
Children
We do not knowingly collect personal information from children or from anyone else. The app has no chat, no links that leave the app, and no way to post anything.
Changes
If this policy changes, the new version will be posted on this page with a new date.
