Privacy Policy

Last updated: October 10, 2026

In short

MathsFun works entirely offline. bdzapps collects no data, the app makes no network request, and everything a child creates stays on the device.

What stays on your device

The app stores on the device, and only there:

• the children's profiles: nickname, class and chosen avatar,
• results and statistics for each session (time, mistakes, success rate),
• settings.

Uninstalling the app deletes all of it.

What goes over the network, and to whom

MathsFun makes no network request. It contains no advertising, no analytics, no crash reporting and no third-party SDK that could collect data.

Children

The app collects no personal information from anyone, whatever their age, including children under 13.

This website

This website (bdzapps.com) sets no cookies, runs no analytics and makes no third-party requests. It is a set of static pages served over HTTPS.

Changes to this policy

If the app's behaviour changes in a way that affects this policy, we will update this page and the date above.
