Last updated: September 10, 2026

Formulens is an offline-first mathematics formula reference. The formula catalog and downloaded lessons are stored on your device. Formulens does not require an account and does not ask you to submit the formulas you browse.

Advertising and consent

Formulens may use Google Mobile Ads. Google and its partners may process device, advertising, diagnostic, and interaction information to provide, measure, and protect advertising, subject to your choices and applicable law. The app uses Google’s consent tools where required and provides advertising and consent options in Settings.

You can review Google’s privacy practices at Google Privacy & Terms.

Downloads and local storage

When you download a supported lesson, the file and its integrity metadata are stored locally so it can be played offline. You can clear downloaded lessons from Settings.
