Privacy & Cookie Notice

Last updated: October 10, 2026.

Calculator inputs

This calculator runs in your browser. Our calculator code does not transmit your wall measurements or roll settings, set cookies, store projects in local storage, or load analytics. Example links contain a reference to a prefilled worked room in the URL. URLs can appear in browser history and hosting request logs, so do not put personal or confidential information into calculator links.

Hosting and technical data

The site is intended to be hosted on Cloudflare Pages. When you request a page, the hosting provider processes technical information needed to deliver and protect the site, such as your IP address and request details. Its practices are described in the Cloudflare privacy policy. We do not promise that infrastructure processes no data simply because the calculator is local.

Contact email

If you email [email protected], the address, message, and any attachments you provide will be processed to respond and investigate the issue. Send only the information needed for your question. You may email the same address to ask about or request deletion of correspondence we retain; some records may need to be kept for legitimate operational obligations.

Cookies and future Google advertising

There are currently no Google ads, advertising tags, or Google advertising cookies installed by this site. We intend to use Google AdSense in the future and will update this notice and the applicable privacy controls before activating ads.

If enabled, Google and other third-party advertising vendors may use cookies or similar identifiers to serve, measure, and personalize ads based on visits to this and other websites. Google's advertising cookies can help Google and its partners deliver ads using browsing activity. Non-personalized advertising may also use cookies for measurement and other advertising purposes. Any other ad vendors used will be identified when introduced.

You can control personalized Google advertising through Google My Ad Center. Information on how Google processes partner-site data is available in Google's partner-site notice. Participating third-party vendors' personalization choices are available through Digital Advertising Alliance choices. Browser settings can block or delete cookies. Those settings may affect other sites and may need to be applied separately on each browser or device.

Changes and questions

This notice describes the current release and the proposed advertising use separately. New advertising or analytics features will require a revised notice and appropriate consent or opt-out controls before use. For privacy questions, email [email protected].
