Calculator data

Calculations run in your browser. This site does not send calculator values to a server, save job history, or use browser storage for those values. Refreshing or leaving a page may reset your inputs.

Hosting

The hosting platform receives ordinary request information needed to deliver the website, such as an IP address and browser information. Private access may also involve the hosting platform’s own authentication.

Advertising and analytics

This version does not include advertising scripts, analytics trackers, affiliate tracking, or newsletter collection. If those features are introduced, this notice must be updated to reflect the services and choices provided.

Printing

Using Print opens your browser’s print dialog. Your device and selected printer control where the resulting document is stored or sent.
