Device and iOS version.

A screenshot if possible.

Common questions

Does the app need an internet connection?
No. Everything runs locally on the device.

Does the app collect any data?
No. See the privacy section below.

Will it run on iPad?
Yes — the same build runs on iPhone and iPad and adapts to both portrait and landscape orientations.

Can I use it in a teaching setting?
Yes, that’s the intent. Each simulator shows the generic equation, substitutes the current slider values, and the practice section quizzes the underlying concepts.

Privacy Policy

Effective 26 May 2026

Information we collect

None. The app does not collect, request, or transmit any personal information, contacts, location data, photos, identifiers, usage analytics, crash logs, or device information.

Information we store on your device

Any state you create while using the app (slider positions, quiz answers, toggles, etc.) is stored locally on your device by iOS and is not sent anywhere. Uninstalling the app removes this data.

Third-party services

The app does not embed any third-party SDKs, analytics, advertising, or tracking. It does not contact any servers and does not require an internet connection.

Children

Because the app does not collect any information, it is suitable for use by people of all ages, including children, without parental consent for data collection.

Changes

If this policy ever changes, the updated version will appear at this URL with a new effective date.
