Privacy

What we collect

The calculators run entirely in your browser — the roof sizes and cities you enter are not sent to us or stored anywhere.

Like most websites, our hosting provider (Cloudflare) records standard server logs (IP address, pages requested, browser type) for security and performance. We may use privacy-respecting aggregate analytics to understand which pages are useful.

Cookies and advertising

The site currently sets no tracking cookies of its own. If we introduce advertising in the future, this page will describe the providers and choices before that happens, and consent will be requested where required by law.
