Numerikill privacy policy

Last updated: October 2026

Numerikill is a math game for children. We built it so that it does not collect, store or share any personal information.

What we collect

Nothing. Numerikill has no accounts, no sign-in, no ads, no analytics, no in-app purchases, no chat and no third-party software development kits (SDKs). The app does not connect to the internet.

What stays on the device

The game saves your child's scores, game options, tilt calibration, a launch counter and the optional parent password only on the device itself. This information is never sent to us or to anyone else. Deleting the app deletes it.

Motion sensor

The game reads the device's motion sensor (accelerometer) while it is open so the player can steer by tilting. These readings are used instantly to move the ship and are not saved or sent anywhere.

Children's privacy

Numerikill was designed with children's privacy laws such as COPPA and the GDPR in mind: it collects no personal information from anyone, including children. There are no links out of the app and nothing to buy.

Changes

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