Privacy policy

Last updated: June 2026.

The short version

Our calculators run entirely in your browser. The dimensions and figures you enter are never transmitted to or stored on our servers.

Information we collect

We do not ask you to create an account or submit personal information to use the calculators. We collect standard, anonymous analytics (such as which pages are visited) to understand which tools are useful and improve the site.

Cookies and advertising

This site is supported by advertising served by Google AdSense. Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to this and other websites. Google's use of advertising cookies enables it and its partners to serve ads based on your visits to our site and/or other sites on the internet.

You may opt out of personalised advertising by visiting Google Ads Settings. For more on how Google uses data when you use our partners' sites or apps, see Google's policies. Where required, a consent banner lets you accept or decline non-essential cookies.
