Privacy Policy

Last updated: October 2026

Calcuter ("we", "our", or "the app") is committed to protecting your privacy. This Privacy Policy explains how Calcuter handles information on your device.

Information we collect

Calcuter does not collect, store, or transmit any personal information. Specifically, we do not collect:

• Your name, email, or contact information
• Your calculations or calculation history
• Your device location
• Usage analytics or telemetry
• Crash reports or diagnostics
• Advertising identifiers

Data storage

All data created in Calcuter — tapes, calculation history, memory slot values, and app settings — is stored locally on your device only. This data:

• Never leaves your device
• Is not shared with us or any third party
• Is deleted when you delete the app

In-app purchases

Calcuter offers an optional one-time "Pro" unlock for unlimited tapes and full PDF export. Purchases are processed entirely by Apple through StoreKit — we never see or handle your payment information, and we don't operate any purchase or account servers of our own. Apple's own privacy policy governs data collected during the purchase process itself.

Third-party services

Calcuter uses only Apple's first-party StoreKit framework to process optional in-app purchases. We do not use any third-party analytics, advertising networks, or data brokers.

Children's privacy

Calcuter does not collect any information from anyone, including children under the age of 13. The app is suitable for users of all ages.

Your rights

Since all data stays on your device, you have complete control over it: uninstall the app, or use any in-app reset option, to remove all data. We don't hold your data, so there's nothing for us to delete on your behalf.

Changes to this policy

We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated date above.
