Privacy policy

Last updated October 17, 2026: added analytics.

What we collect

Nothing that identifies you. This site has no accounts, no comment forms and no advertising scripts, and it sets no cookies. The email signup shown on some pages is not live and does not collect or store anything.

Analytics

We use Cloudflare Web Analytics to count visits and see which pages are useful and how quickly they load. Cloudflare says it does not use cookies or browser storage for this and does not fingerprint visitors by IP address or browser details. It reports things like the page you viewed, the site that referred you, and page load times, and we only see totals. Read Cloudflare's description of what Web Analytics collects.

Hosting

The site is hosted on Cloudflare. Like any web host, Cloudflare processes technical request data (such as IP addresses) to deliver pages and protect against abuse. See Cloudflare's privacy policy for details.

Links to other sites

We link to government agencies, certification directories and retailers. When you follow a link, that site's privacy policy applies. Our links to radon monitors are affiliate links, which let the retailer know you came from this site.

Changes

If we ever start collecting information, such as newsletter signups, we'll update this page first and ask for your consent where required.
