What we collect

Nothing through the site itself. There are no accounts and no forms that send data. The site does not use cookies, analytics or advertising.

The numbers you enter in the calculators are processed in your browser and are not sent to us or to anyone else.

Data stored on your device

Your choice of metric or imperial units is saved in your browser's local storage so the site remembers it. It never leaves your device, and you can delete it at any time by clearing this site's data in your browser.

Hosting

The site is hosted by Cloudflare Pages. Like any web host, it may record technical data such as your IP address and browser type in server logs in order to deliver and protect the site. See the host's own privacy policy for details.

If you email us

We use your email address and message only to reply to you.

Changes to this policy

If we add analytics or advertising in the future, we will update this policy before they go live and, where the law requires it, ask for your consent first.

Your rights

Depending on where you live, you may have the right to access, correct or delete personal data, or to object to its use. Write to us at the address above.
