Math Ninja ("the app") is a math practice game for kids, currently in development. As built today: the app collects nothing and sends nothing anywhere.
Information we collect. None. All practice data — including what the parent dashboard shows (mastery, accuracy and speed trends, trouble spots) — lives on the iPad and is computed there. Nothing is transmitted off the device.
Information stored on the device. Up to six player profiles, each with its own progress, belts, and unlocked blades, are stored only on the device. Deleting the app removes them.
Internet and third parties. The app has no network features: no accounts, no sign-in, no third-party analytics, tracking, or advertising software.
Children's privacy. Because the app collects no data at all, it does not knowingly collect personal information from children under 13. It is being built to comply with COPPA and Apple's guidelines for apps directed at kids.
Purchases. No in-app purchases or subscriptions of any kind. All blade unlocks are earned in play, free.
