Your Privacy

Last updated: May 2026

Numinion does not collect, transmit, or share any personal data. All calculations happen locally on your device.

What We Collect

Numinion does not collect any personal information. The app stores the following data locally on your device only:

Calculation history (stored in device memory)
Custom programs and formulas you create
Angle mode and calculator preferences

None of this data is ever transmitted off your device.

Internet Access

Numinion requests internet access for one optional feature only: fetching live currency exchange rates from open.er-api.com. This request contains no personal information — only a request for publicly available exchange rate data.

All other features (calculator, grapher, unit converter, RPN mode, programs) work fully offline.

Third-Party Services

Numinion does not use any third-party analytics, advertising SDKs, crash reporting tools, or tracking frameworks. There are no user accounts, no servers, and no in-app purchases that transmit personal data.

Data Storage

All app data is stored locally using Apple's standard storage APIs (UserDefaults and local file storage). Deleting the app permanently removes all stored data from your device.

Children's Privacy

Numinion does not collect data from anyone. Since no data leaves the device, there are no age-based restrictions on data handling.

Changes to This Policy

If this policy changes, the updated version will be posted at this URL with a new "Last updated" date. Significant changes will also be noted in the App Store release notes.
