Your measurements stay on your device

Every calculation runs in your browser. The measurements, prices and densities you enter are not sent to us or stored on a server. Copying the shopping list uses your device's clipboard only.

Your browser keeps your latest inputs in its local storage on this device, so they are still there when you come back. Use Start over to clear them, or clear this site's data in your browser settings.

Copy link puts your inputs inside the link itself, after the # sign. Browsers do not send that part of a link to the server, so the estimate travels only to the people you share the link with.

No accounts, cookies or ad trackers

The site has no sign-up, sets no cookies and does not load advertising or social-media tracking scripts. The local storage described above stays in your browser and is never read by us.

Hosting

The site is served by Cloudflare. Like any web host, Cloudflare processes technical request data such as IP address and browser type to deliver and protect the site. See Cloudflare's privacy policy for details.

Changes

If we add privacy-friendly, cookieless visitor statistics or anything else that changes how data is handled, this page will be updated first, with a new date.
