What we collect

Nothing you type into our calculators is sent to our servers. All calculations run entirely in your browser. Material calculators keep one draft per material in your tab's browser session storage, including dimensions, product details, project name, notes and paper size, so you can leave a page and return. Drafts are not synced to an account or another device. Use “Clear draft & start new” in the calculator to remove that material's draft; your browser may also restore session data when restoring a closed tab or session.

We use standard server logs (IP address, browser type, page visited, timestamp) for security and performance purposes. These are not sold or shared with third parties.

Cookies

We do not use tracking cookies or third-party analytics at this time.

External links

When we link to partner sites (contractors, retailers), those sites have their own privacy policies. We do not share your information with them before you click.
