Frequently Asked Questions
Q. Does CalcPure have ads or in-app purchases?
A. No. CalcPure is a one-time paid app with no ads, no tracking, no in-app purchases, and no subscriptions. Every feature — basic, scientific, and programmer modes, all themes, and memory functions — is available from the moment you install it.
Q. Does CalcPure collect my data?
A. No. We do not collect, store, or transmit any personal data. All calculations and history stay on your device.
Q. How do I get CalcPure on a new device?
A. Sign in to the new device with the same Apple ID you used to buy CalcPure, then re-download it from the App Store — either from your purchase history or by searching for the app. There is no separate restore step, because there are no in-app purchases to restore.
Q. The calculator history is not saving. What should I do?
A. Check your device storage and ensure the app has permission to write data. If the issue persists, please contact us by email.
Q. Which devices and OS versions are supported?
A. CalcPure supports iPhone and iPad running iOS 16.0 or later.
