Privacy Policy

Last updated August 2026

Radix is a vocabulary-learning app built to work entirely on your device. This page describes, plainly, what that means for your data.

What we collect

Nothing. Radix has no accounts, no analytics, no advertising, and no server. All of your progress, practice history, and Caught in the Wild entries are stored locally on your device and never leave it.

Notifications

If you turn on the daily reminder, Radix schedules a local notification directly on your device using Apple's notification system. This never touches a server — there's no push service and no third party involved.

Third parties

Radix does not use any third-party analytics, advertising, or tracking services of any kind.

Children's privacy

Radix was built for a middle-schooler and is safe for kids: no ads, no in-app purchases, no data collection, and no communication with the outside world of any kind.

Changes to this policy

If this policy ever changes, we'll update this page and the date above.
