Core conversions are calculated in your browser. Typed deterministic conversion queries do not need to be sent to a server.

Local storage

The app can store theme, precision, favorites, conversion history and imported/custom currency-rate data in localStorage under the bqtools.convert.* namespace. You can disable or clear history from the History panel and reset preferences in your browser storage.

Currency data

Bundled reference rates are static, dated data. If a future first-party /api/rates endpoint is enabled, requesting a refresh can contact that same-origin endpoint. Imported files stay in your browser unless you separately send them elsewhere.

Analytics

This site uses Google Analytics 4 with measurement ID G-EFD3YS3VKJ for aggregate site-usage measurement. Analytics is not required for converter functionality. The analytics loader strips query strings and URL fragments from page-location and referrer values, and the application does not intentionally send typed conversion queries, conversion history, favorites, imported data or custom currency rates to Google Analytics. Google Analytics may use cookies or similar browser storage according to Google's service behavior and your browser/settings.
