Data we store

Unit Converter AI stores a small amount of data in your browser's local storage: your theme preference (light/dark) and, if you use the currency converter, cached exchange rates for up to one hour.

Data we do not collect

We do not collect personal information, conversion history, or analytics. All standard unit conversions run entirely in your browser and are never sent to a server.

Currency rates

The currency converter fetches exchange rates from the Frankfurter API (a free, open exchange-rate service). Only the base currency code is sent in that request — no personal data.
