Privacy

Effective November 15, 2026. Materials is a browser-based calculator site operated as part of Designs24hr. We do not collect, store or keep any personal data or records.

Calculator information

Calculations run in your browser. Calculator inputs stay in your browser and are not sent to us or saved by us. If you save an estimate, a project name or a PDF paper size on this device, that information stays in your browser only. You can clear it with the project-list control or your browser settings.

PDF downloads and sharing

PDF documents are assembled in your browser. Downloading a PDF saves a file on your device. Choosing Share PDF may send that file to an app or service you choose on your device. If sharing is unavailable, the site downloads the PDF instead.

Analytics and advertising

Google Analytics and Google AdSense may set their own cookies. See Google advertising technologies and Google ad settings to opt out.

Your choices

You can use the calculators without saving a project list, and you can clear a saved list in the app or in your browser. For questions about this policy, see Contact.
