• GlenCalc has no accounts, sets no cookies and runs no analytics or advertising scripts.
• The numbers you type are worked out in your browser and are never sent to us. They are kept in the page address after the # sign so you can bookmark or share the result. Browsers do not send that part of the address to any server, but anyone you send the link to can see the numbers.
• Site search runs in your browser too: what you type in the search box is not sent anywhere.
• The optional API is different: requests to it are processed on Cloudflare’s network to return the answer. GlenCalc does not store them.
• Our host, Cloudflare, processes standard request data (such as IP address and browser type) to deliver and protect the site.

If this changes, for example if we add advertising, we will update this page first. Questions: [email protected].
