Short version: the numbers you type stay on your device.

Calculator inputs

Every calculation runs in your browser. The measurements and prices you enter are not sent to our server or anyone else.

If you press Save, the estimate is stored only in this browser on this device, and you can delete it at any time. If you press Share, the numbers are written into the link itself, so whoever you send the link to can see them.

Offline use

The site stores copies of its own pages in your browser so they keep working without a connection. That cache holds only the site’s pages, never your numbers.

Visit statistics

We count visits with Cloudflare Web Analytics, which does not use cookies and does not track you across sites. It shows things like how many people opened a page and from which country, never what you typed.

Ads

The site does not show ads at the moment. If ads are added later, this page will say which company provides them and how to opt out.
