Privacy Policy — NumberNebula

Last updated: 10 July 2026

NumberNebula is designed for children and built to be private by default.

Data we collect

None. NumberNebula does not collect, transmit, sell, or share any personal information. There are no user accounts, no sign-in, and no analytics or advertising SDKs. The app does not track you across apps or websites.

Data stored on your device

The app saves your game progress, difficulty settings, and learning statistics (for example, which math facts you have mastered) locally on your device only, using the operating system's standard on-device storage. This data never leaves the device, is not accessible to us, and is removed when you delete the app.

Network access

NumberNebula runs fully offline. It does not require an internet connection to play and makes no background network requests to us.

Purchases

Any in-app purchases are processed entirely by Apple through the App Store. We do not receive or store your payment information; Apple's own privacy policy governs that transaction.

Children's privacy

Because the app collects no personal data at all, it is suitable for children and complies with children's-privacy requirements such as COPPA and GDPR-K by design.
