Zuzu Lab (“we,” “our,” or “us”) respects your privacy and the privacy of your children. We created Math Warrior to be a safe, educational way for children from Kindergarten to Grade 5 to practice math. This Privacy Policy explains our data practices.
To remember each child’s progress, the app saves the following on your device only: the names, grades, and avatars you enter for each child; their stars, coins, levels, practice history, and settings; and a scrambled (salted SHA-256) copy of the parent passcode — never the passcode itself. This data is stored using Apple’s native frameworks (UserDefaults and the app’s own storage). We have no access to it, and it is never transmitted to us or to any third party.
If your device is backed up to iCloud or a computer, this data is included in that backup like other app data; backups are handled by Apple under your own device settings.
You can reset a child’s progress or delete a child’s profile in the parent area. Deleting the app permanently removes everything it saved.
When “Read questions aloud” is on, the app speaks using Apple’s built-in text-to-speech on your device. No audio is recorded, and the microphone is never used.
Math Warrior contains no in-app purchases, no advertising, no subscriptions, and no external links. The coins children earn are play rewards inside the game only. Settings and progress reports are kept behind a parent passcode.
Math Warrior is made for children from Kindergarten to Grade 5. Because we collect no personal information from anyone, we collect none from children.
If we change this policy, we will update the “Last Updated” date above and post the revised version at this address.
If you have any questions or concerns about this Privacy Policy or our practices, please contact us.
