Your measurements stay in your browser

Calculator inputs are processed on your device. This site does not send them to a database, save project histories, or require an account. Reloading a page clears entered values.

Hosting and third parties

The hosting provider may process technical information such as IP addresses and request logs to deliver and protect the site. This site currently adds no advertising, analytics, tracking cookies or external fonts. Hosting-platform access or session mechanisms are separate from calculator functionality.

Copying and printing

Copy uses your device clipboard when you request it. Printing uses your browser’s print dialog. Be mindful of where you paste or save your estimates.

Future changes

If advertising or analytics are added, this notice and any required consent controls must be updated first.
