Privacy Policy

What we collect

Block Build Tools has no accounts and no sign-up. Every tool runs entirely in your browser: the sizes and coordinates you enter and your results are never sent to us or stored on our servers.

Hosting and logs

The site is hosted on Cloudflare, which may process standard request data such as IP address and browser type to deliver and protect the site.

Advertising and analytics

If we add advertising or analytics in the future, those providers may use cookies, and this policy will be updated to describe them before they go live.

Children

The site is a general-audience tool and does not knowingly collect personal information from anyone, including children under 13.
