Privacy Policy
Last updated: March 2026
The short version
Matrun does not collect, store, or share any personal information. No accounts, no tracking, no ads.
No data collection
Matrun is a simple math practice app designed for children. It does not collect any personal information — not your name, age, location, email address, or any other identifying data.
No internet connection required
Matrun works entirely offline. The app never connects to the internet and never transmits any data to any server.
Local data only
Stats such as the number of questions answered and difficulty settings are stored only on your device and are never sent anywhere. Deleting the app removes all of this data.
No third-party SDKs or analytics
Matrun contains no advertising SDKs, analytics frameworks, or any third-party code that could track usage or collect data.
Children's privacy
Matrun is designed for young children. Because we collect no data whatsoever, the app fully complies with the Children's Online Privacy Protection Act (COPPA) and similar regulations worldwide.
