Calculator inputs
Calculator values are processed in your browser. We do not send them to a backend, save them to an account or include them in analytics. Closing or reloading the page resets unsaved input unless you opened a shared URL.
Shared links and downloaded reports
Choosing Share creates a URL fragment that contains the values you entered. Anyone receiving that link can read those values. Only share links with people you intend to see them. CSV exports are generated locally and saved to your device.
Cookies, hosting and third parties
This implementation does not set tracking cookies or load advertising or analytics scripts. The hosting service may process routine request information, such as IP addresses and browser details, to deliver and protect the website. External source links take you to sites governed by their own privacy policies.
Updates
This policy reflects the current browser-based implementation, dated September 18, 2026. It must be reviewed before adding accounts, analytics, subscriptions or other services that process personal information.
