What we collect
You don’t need an account. The measurements you type are processed in your browser and are not sent to us.
Your project list
Items you add to your project list are stored in your browser’s local storage on your device. We can’t see them. Clearing your browser data deletes them.
Share links
A share link contains your measurements after the # in the address. That part of a link is not sent to our server when someone opens it.
Analytics
If analytics are enabled, we use a cookieless, privacy-focused service that counts visits and feature use without collecting personal data.
Advertising
We may show ads from Google and its partners. 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 visits to this site and other sites. You can opt out of personalized advertising at Google Ads Settings, and learn more at how Google uses information from sites that use its services. Where required by law, we ask for consent before any advertising cookies are set.
