Your calculator inputs

Every calculation on CalcVitals happens in your own browser. The figures you type are never sent to us, saved by us, or shared by us. There are no accounts and no sign-ups.

Advertising

This site is supported by advertising served by Google AdSense. Google and its partners may use cookies to serve ads based on your prior visits to this and other websites. You can opt out of personalised advertising at Google Ads Settings, and learn how Google uses data from sites that use its services at policies.google.com.

Analytics

We may use privacy-respecting aggregate analytics to count page visits. Aggregate counts never include the values you enter into a calculator.

Embedded calculators

Sites that embed our calculators load them from calcvitals.com; the same in-browser rule applies — inputs stay in the visitor's browser.
