Formulo Calculator Privacy Policy

Summary

Formulo Calculator does not collect, transmit, sell, or share any personal data. The app works entirely on your device.

What Data Formulo Stores

Your sheets, formulas, constants, and settings are saved automatically using your device's local storage (or, in the iOS app, on-device app storage). This data never leaves your device unless you explicitly export it.

CSV Export and Import

Exporting a sheet creates a CSV file that you choose where to save (for example, to the Files app). Importing reads a CSV file you select. Both actions happen entirely on-device — Formulo has no server and does not upload your files anywhere.

No Analytics or Tracking

Formulo does not use analytics, advertising, or tracking software of any kind, and does not make network requests to any third party.

No Account Required

Formulo does not require sign-in and does not collect your name, email, or any other identifying information.

Children's Privacy

Because Formulo collects no data of any kind, it does not knowingly collect personal information from anyone, including children.

Changes to This Policy

If this policy ever changes (for example, if a future version adds optional cloud sync), this page will be updated and the "Last updated" date above will change.
