Privacy & Cookie Notice

Last updated: October 11, 2026.

Calculator inputs

Our calculator code runs in your browser. It does not transmit dimensions to a calculation service, save projects in local storage, set cookies, or load analytics. Example links contain a preset identifier in the URL. Page URLs may appear in browser history and hosting logs. Do not put personal information in URLs.

Hosting

The site is intended for Cloudflare Pages. A hosting provider can process your IP address, request details, and other technical data needed to deliver and protect pages. See the Cloudflare privacy policy for that provider’s practices.

Contact email

If you email [email protected], your address, message, and attachments are processed to answer the question and investigate the issue. Send only what is needed. You can use the same address to ask about retained correspondence or request deletion; operational obligations may require some records to be retained.

Cookies and advertising

No analytics, Google advertising tags, or advertising cookies are installed by this release. If advertising is introduced later, this notice and applicable privacy controls will be updated before activation.
