Just Calc. ("the app") is a scientific calculator for iPhone and iPad. This policy explains what information the app handles.
Your calculations, history, settings (theme, language, fonts and so on) and any programs you write are stored only on your device. We do not have accounts, we do not upload this content, and we cannot see it.
We do not collect your name, email address, contact details, location or any account information. The app has no sign-in.
The free version shows ads provided by Google AdMob. To serve and measure ads, Google's advertising SDK may collect and use certain data from your device, such as:
This data is collected and processed by Google under Google's Privacy Policy, not by us. You can limit ad personalisation in iOS Settings → Privacy & Security → Tracking and Apple Advertising.
The paid version (Premium) shows no ads.
Premium is a one-time in-app purchase handled entirely by Apple. We do not receive or store your payment details. Apple tells the app whether Premium is unlocked on your Apple ID, so you can restore it on other devices.
The app is a general calculator and is not directed at children under 13. We do not knowingly collect personal information from children.
If this policy changes, we will update the date above. Continued use of the app means you accept the updated policy.
