Privacy Policy

Last updated June 9, 2026

Short version: this is a free calculator site. We don’t want your personal data and we don’t collect it.

Your calculations stay in your browser

Every calculator on this site runs entirely in your web browser. The numbers you type are used to do the math on your own device — they are never sent to us, never saved, and never shared. Close the tab and they’re gone.

The room dimensions, square footage, and material quantities you enter are used only to run the estimate on your own device — we never see your house, your project, or your numbers.

What third parties might see

• Fonts: we load typefaces from Google Fonts, which may log standard request data such as your IP address under Google’s privacy policy.
• Traffic measurement: we may use a privacy-friendly, cookie-free analytics tool (such as Cloudflare Web Analytics) to see how many people visit. It does not use cookies and does not collect personal information.
• Advertising: this site does not currently show ads. If that changes, third-party ad vendors (such as Google) may use cookies to serve ads; you can opt out at google.com/settings/ads, and this page will be updated to say so.

Affiliate links

This site currently has no affiliate relationships. Outbound “where to buy” links are plain, untracked search links — we earn nothing when you click them. If affiliate links are ever added, that relationship will be disclosed clearly on this page and next to the links themselves.

Your rights (CCPA / GDPR)

We do not sell personal information, and because the calculators run locally we hold essentially none. If you have a privacy question, email [email protected].
