Before contacting us
- Restore a purchase: Use “Restore Purchases” in app settings, and check that the Apple or Google account used for the purchase is signed in.
- Calculation issue: Include the expression, expected and actual results, DEG/RAD setting and app version. Please remove personal information from expressions before sending them.
- Ads and consent: If “Privacy Settings” appears in app settings, you can change your choice there. Core calculations work even without an ad.
- Data deletion: Delete local calculation history in app settings. Contact us about purchase-verification records using the email above. We will explain the minimum order identifier needed; never send a password, full receipt or card number.
Accounts and payment
Eqnora does not create its own member accounts. The store where you made a Pro purchase handles payment and refunds under its policies. The app does not receive card numbers.
