Privacy Policy

Last updated: July 23, 2026

This Privacy Policy describes how Arithmetic (“the app”) handles information. Arithmetic is designed to be private by default: it does not collect, store, or transmit any personal data.

Information We Collect

None. Arithmetic does not collect any personal information. We do not ask you to create an account, sign in, or provide any personal details to use the app.

Data Stored on Your Device

The app saves your practice data — such as drill results, scores, session history, and progress statistics — locally on your device only. This information:

• Never leaves your device;
• Is not transmitted to us or to any third party;
• Is not accessible to us in any form;
• Is permanently removed when you delete the app.

No Tracking or Analytics

Arithmetic contains no analytics, no advertising, no tracking technologies, and no third-party software development kits (SDKs). We do not track your activity across apps or websites.

No Network Connections

The app functions entirely offline and does not send your data over the internet.

Children’s Privacy

Because Arithmetic collects no data whatsoever, it is safe for users of all ages, including children. We do not knowingly collect any information from anyone.

Changes to This Policy

If this policy changes, the updated version will be posted on this page with a revised “Last updated” date.
