Privacy policy

Last updated 11 October 2026

This policy explains what information the Calcurate app and this website handle. In short: the app has no accounts, keeps your settings on your device, and does not sell or share personal data.

The app

  • No account. You do not sign up or log in.
  • Settings stay on your device. Your base currency, currency keys, display tint, keycap set and sound setting are stored locally. Cached exchange rates are also stored locally.
  • Exchange rates. To get rates, the app requests them from ExchangeRate-API (open.er-api.com) and, as a fallback, Frankfurter (api.frankfurter.dev). Like any web request, these services receive your IP address and basic request information. No personal information from the app is included in these requests.
  • Widgets. On iOS, the widget shares settings and rates with the app through an App Group on your device. On Android, widgets read the app's cached rates on your device.
  • Permissions. The app does not request access to your microphone, location, contacts or photos.
  • App stores. Apple and Google may collect information under their own privacy policies when you download or use apps from their stores.

This website

  • Pages may request exchange rates from ExchangeRate-API in your browser to show live figures.
  • Fonts are loaded from Google Fonts, which receives your IP address when it serves them.
  • We may use Cloudflare Web Analytics, which does not use cookies, to count page views.
  • The site remembers if you dismiss the install banner using your browser's local storage.

Children

Calcurate is a general-audience calculator and does not knowingly collect personal information from anyone, including children.
