Privacy & analytics

Calculations run in your browser. Our anonymous analytics records the tool ID, event type, time and a broad traffic source such as Google or direct/unknown. We do not store calculator inputs, full referrer URLs, or persistent visitor identifiers in this analytics database.

A random event ID prevents duplicate counting when a request is retried. Hosting providers still process network requests to serve the site. Browser blocking may prevent analytics.
