Privacy Policy

What we collect

The calculators run entirely in your browser. The measurements, prices and settings you enter are never uploaded to our servers.

Like most websites, our hosting provider may keep standard server logs (such as IP address, browser type and the pages visited) for security and to keep the site running.

Analytics

We use Cloudflare Web Analytics to count visits and see which pages are popular. It does not use cookies, does not track you across other websites and does not collect personal information. See Cloudflare Web Analytics for details.

Advertising and cookies

This site does not currently display advertising or load Google AdSense code. We do not currently provide an advertising consent message or a cookie-settings control.

If we introduce advertising, we will update this policy to describe the providers, cookies and controls actually in use, and implement the consent mechanism required for the regions where ads will be served before enabling them.

Children

Our pages are written for parents, teachers and other adults. This site does not knowingly collect personal information from children.
