Privacy Policy — TonCalc: Gravel Calculator

Effective October 11, 2026

TonCalc is made by fruitfulapps. This policy explains what the app does with your information. The short version: we don't collect any.

What we collect

Nothing. The app has no account, no sign-in, no analytics, no advertising and no tracking. It does not request access to your location, contacts, camera, photos or files.

What stays on your phone

Your measurements, saved jobs, custom materials and settings are stored only on your device. They are never sent to us or anyone else. Deleting the app deletes them.

Purchases

The optional one-time Pro unlock is processed by Apple (App Store) or Google (Google Play). We use RevenueCat, Inc. to check whether Pro is unlocked; it receives an anonymous app-generated identifier and the store's purchase receipt, never your name, email or payment details. See RevenueCat's privacy policy. Apple and Google handle payment under their own privacy policies.

Sharing

When you tap Share or Copy, the app hands a text summary of your estimate to the place you choose. We don't see it.

Children

The app is a general-audience tool and is not directed at children under 13. It collects no personal information from anyone.

Changes and contact

If this policy changes we will update this page and its effective date. Questions: fruitfulapps@gmail.com.
