Subtraction for Kids: Math · Last updated 17 July 2026
None. Subtraction for Kids: Math does not collect, transmit, sell, or share any personal data. We have no accounts, no sign-in, no analytics, no advertising, and no third-party SDKs that gather information. The app works fully offline.
This app is designed for children ages 6–8 and is intended for the Kids Category. It does not collect any personal information from children or anyone else. It contains no ads, no external links available to children, and no social features. Any action that leaves the app or involves a purchase is placed behind a parental gate.
The app offers a single one-time in-app purchase (“Unlock Everything”, a lifetime unlock) processed entirely by Apple through the App Store. We never see or receive your payment details. Apple’s handling of that transaction is governed by Apple’s own privacy policy. Your purchase status is stored only on your device so the app works offline after purchase.
The app requests no permissions — no camera, microphone, photos, contacts, location, or notifications.
Simple settings (such as whether onboarding is complete and whether sound is on) are saved locally on your device using standard iOS storage. This information never leaves the device.
If this policy changes, the updated version will be posted on this page.
