  • Local preferences such as selected currencies, language, and app settings stored on the device.
  • Local calculation history stored on the device when the feature is enabled.
  • Network requests sent to the exchange-rate provider at https://api.frankfurter.dev to download current currency rates.
  • Advertising-related data that may be processed by Google AdMob, such as device identifiers, approximate location, IP address, diagnostics, and ad interaction data, depending on the user device, region, and Google settings.

The app uses Google AdMob to display ads. AdMob may collect and process data to provide, measure, and improve advertising. Ads may be personalized or contextual depending on the user device, region, consent status, and Google settings. For more information, see:

5. Data sharing

We do not sell your personal data directly. However, third-party services used by the app, such as Google AdMob and the exchange-rate provider, may receive technical request data needed to deliver their services.

6. Data retention

Preferences and calculation history remain on the device until the user clears the app data, uninstalls the app, or manually changes settings inside the app.

7. Children’s privacy

This app is intended for a general audience and is not specifically directed to children. If you believe that a child has provided personal data through a third-party service used by the app, please contact us and we will review the issue.
