Calculations run in your own browser. Normal calculations do not upload your inputs. A share link places inputs in the URL: anyone with it can read them, and opening it sends that URL to the hosting server. Avoid sharing sensitive personal or financial information. Currency conversion separately requests public exchange rates.

Ads and analytics

Free pages show ads from third-party networks such as Carbon Ads, EthicalAds or Google AdSense. These partners may use cookies or similar technologies to serve and measure ads. Visitors in regions that require consent will be asked before personalized ads load.
