Number Ninjas — Privacy Policy

Last updated: June 19, 2026

Number Ninjas is built for kids to practise maths, not to watch them. The whole policy in one sentence: everything happens on your device and nothing is collected, stored on our servers, or shared — because we have no servers.

What we collect

Nothing. Number Ninjas has no accounts, no sign-ups, no analytics, no advertising, and no third-party tracking SDKs. We never receive any information about you or your device.

Permissions

The app requests no permissions at all — no location, contacts, camera, microphone, or notifications. It also requires no internet connection and works fully offline.

Data storage

Your best score and game preferences are stored only on your device using standard on-device storage. Deleting the app deletes all of it. We keep no copy of anything.

Children's privacy

Number Ninjas does not collect, store, or share personal information from anyone, including children. It contains no ads, no in-app purchases, and no links out to the web or social media.

Changes to this policy

If this policy ever changes, the new version will be posted on this page with an updated date.
