Privacy
The estimator runs in your browser. It doesn't set cookies, and it never asks for your name, email or address.
What your browser keeps
Your browser's local storage holds your unit choice, shape and waste setting (ce_units, ce_shape, ce_waste), so the page reopens the way you left it. Your measurements are never sent to us. They appear in the page address only so that you can share it.
What gets counted
A small usage note goes to the server that belongs to this site. It covers the device type and the shape used, plus which page was viewed and the site that sent you. It stores no measurements, and nothing in it names you. For security and traffic totals, our host holds standard request logs covering the IP address, browser and page.
Your privacy choices
There are no ads, no third-party scripts and no tracking pixels, and we never sell or share data. There's nothing to opt out of. If you clear this site's storage in your browser, the three saved settings go away.
