Privacy

Your calculations never leave your browser

Every calculator on this site runs entirely in your browser. The dimensions, prices and labels you type are never transmitted to us, because there is no server to transmit them to — these pages are static files.

What is stored on your device

When you use a calculator, your most recent project is saved in your browser's local storage so it is still there when you come back. It holds only the values you entered. It stays on that device, is never sent anywhere, and you can clear it with the "Start fresh" button or by clearing your browser's site data.

Your project is also encoded into the page's address so you can bookmark or share it. That means a link you share contains the dimensions and prices in that project — worth knowing before you send one to someone.

Accounts

There are none. There is nothing to sign up for and no email address to give us.

Advertising

This site does not currently serve advertising. When it does, this page will name the network and link to its privacy policy before any ad script runs.

Analytics

No third-party analytics or tracking scripts are loaded. If that changes, this page will say so first.
