Instant Converter is a unit conversion app that runs entirely on your device. Your privacy is important to us — this app is designed to work without collecting, storing, or transmitting your personal data.
None. Instant Converter does not collect any personal information.
The app stores the following data locally on your device using your operating system's standard preferences storage:
App preferences — theme selection (light/dark/system), keyboard autofocus setting, always-on-top preference
Recent conversions — your last 10 conversions for quick access
Favorite conversions — conversions you've starred
Calculator history — your last 30 calculations
Currency rate cache — the most recently fetched exchange rates and their timestamp
This data never leaves your device. It is not backed up to any server, not synced across devices, and not accessible to us or any third party.
The app makes a single type of network request:
Currency exchange rates — fetched from frankfurter.dev, a free, open-source API powered by the European Central Bank. This request contains no user data — only a standard HTTP GET request for the latest rates. No cookies, tokens, or identifiers are sent.
All non-currency conversions work fully offline with no network access.
None. The app does not include any analytics SDKs, crash reporting tools, advertising frameworks, or tracking mechanisms.
The only third-party service used is:
Service: frankfurter.dev
Purpose: Currency exchange rates
Data Sent: None (anonymous GET request)
The app does not collect data from anyone, including children. It is safe for use by all ages.
Since all data is stored locally on your device, you can delete it at any time by:
Uninstalling the app, or
Clearing the app's data through your device settings
If we update this privacy policy, we will update the "Last updated" date above. Since the app collects no data, changes would only reflect new features.

This privacy policy applies to the Instant Converter app available on macOS, iOS, Android, and web.
