Privacy policy

Last updated October 11, 2026

Radionuclide Cards is built to work without collecting your personal data. There is no account, no advertising and no tracking. This policy explains what the app stores and where.

Data the developer collects

None. The app does not send your answers, collection or usage to the developer or to any third party, and it contains no analytics or advertising software.

Data stored on your device and in iCloud

Your progress (collected cards, quiz answers, streaks, streak freezes, medals and settings) is stored on your device. If iCloud is turned on, it is also saved in your private iCloud database so it can sync across your devices. That data is held by Apple under your Apple Account, and the developer cannot access it. Apple's handling of iCloud data is covered by the Apple Privacy Policy.

Apple Intelligence explanations

Explanations are generated on your device by Apple Intelligence. The question and your answer are not sent to the developer.

Notifications

If you turn on the daily reminder, it is scheduled on your device. No push notification service or server is involved.

Sharing

When you share a card or a quiz result, the app creates an image and hands it to the iOS share sheet. Nothing is shared unless you choose where to send it.

Diagnostics

If you have chosen to share analytics with app developers in your device settings, Apple may provide anonymised crash reports and usage statistics to the developer. You can change this in Settings under Privacy & Security, Analytics & Improvements.

Deleting your data

Deleting the app removes its data from your device. To remove the iCloud copy, go to Settings, tap your name, then iCloud, Manage Account Storage, and delete the data for Radionuclide Cards.

Children

The app does not collect personal information from anyone, including children.

Changes

If this policy changes, the new version will be posted on this page with an updated date.
