Privacy policy
Last updated 3 November 2026.
Conversions stay on your device
All unit, number-base and text-case conversions run in your browser. The values you type are not sent to our servers.
Local storage
We store your theme choice, conversion history and saved conversions in your browser’s local storage so they are there when you return. You can clear them at any time from the universal converter or through your browser settings.
Currency rates
When you open a currency page, your browser requests exchange rates from the Frankfurter API (api.frankfurter.dev). That request reveals your IP address to the API provider, as any web request does.
Advertising and analytics
We do not currently show advertising. If we introduce ads (for example Google AdSense), this policy will be updated before they go live, and consent will be requested where required by law. We do not currently use analytics cookies.
