Math Ninja is built to be played, not to collect data. This policy explains, in plain language, what the app does and does not do with information.
Nothing. Math Ninja has no accounts, no analytics, no advertising, no tracking, and no servers of our own. We never see who you are or how you play.
Your game progress — unlocked stages, best scores, local leaderboards, and settings (music, sounds, haptics) — is stored only on your device. Deleting the app deletes this data. It is never transmitted to us or to anyone else.
If you choose to sign in to Apple's Game Center, your best scores are submitted to the "Hall of Blades" global leaderboards under your Game Center nickname. This feature is operated entirely by Apple under Apple's own privacy policy. Math Ninja works fully without Game Center; declining it only hides the global leaderboards.
The one-time unlock is processed entirely by Apple through the App Store. We never receive or store any payment information.
Math Ninja is suitable for children. Because the app collects no data of any kind, no personal information about children (or anyone else) is gathered, stored, or shared.
If a future update ever changes any of the above, this policy will be updated and the change will be noted in the app's release notes before it takes effect.
