Privacy Policy

BuildCalc is designed to collect almost nothing. There are no accounts, no sign-ups, and nothing you type into a calculator is sent to a server.

Last updated: 10 November 2026.

What we collect

Calculator inputs: nothing. Every calculator on this site runs entirely in your browser. The measurements you type — room sizes, areas, depths — stay on your device and are never sent to us or to anyone else.

Accounts: none. There is no way to create an account on BuildCalc, so we hold no usernames, passwords or profiles.

Contact emails: if you email us at hello@buildcalc.com, we receive your email address and whatever you write. We use it only to reply to you and to fix the problem you report. We do not sell, share or add your address to any list.

Hosting and logs

BuildCalc is hosted on Cloudflare Pages. Like any web host, Cloudflare may keep standard web-server logs (for example, the pages requested and the time) for security and performance. We do not use those logs to identify individual visitors.

Cookies and third parties

BuildCalc itself sets no cookies. Some pages link out to retailers (see our Affiliate Disclosure), and those sites may set their own cookies under their own privacy policies. If advertising is added to the site in future, this policy will be updated before it goes live. See our Cookie Policy.

Children

BuildCalc is a general-audience site about home-improvement materials. We do not knowingly collect personal information from children, and there is nothing on the site that asks a child for it.

Changes

If this policy changes, the updated version will be posted here with a new “last updated” date. Questions about this policy can be sent to hello@buildcalc.com.
