Privacy Policy

Short version: the calculators run locally in your browser and the numbers you type stay there.

What we collect

No accounts, no sign-ups, no personal data forms. Values entered into a calculator are processed in the page and are not transmitted to a server or saved between visits.

Cookies

No advertising or tracking cookies are set by the calculators themselves.

Server logs

Standard web server logs (IP address, user agent, requested URL) may be recorded by the hosting provider for security and reliability.
