What this site collects
Nothing that identifies you. The calculator runs entirely in your browser; the dimensions you enter are never sent to a server. The “copy link” button puts your inputs in the page address so you can share or bookmark the result, and that address stays with you.
Cookies and storage
The site sets no cookies and uses no analytics or advertising scripts at this time. If that changes, this page will say so and a consent banner will be shown where the law requires it.
Fonts and hosting
Fonts are served from this site's own server, not from Google. Server logs record the IP address and requested page for a short time for security and error analysis only.
