RadonGrade (radongrade.com) respects your privacy. You do not need an account, and we do not ask for personal information to use this site. ZIP codes you type into the lookup are matched in your browser against a static data file; they are not sent to us.

Analytics

We use Google Analytics to understand aggregate traffic (pages viewed, general region, device type, which links are clicked). This data is not used to identify you individually. Analytics load only after you accept cookies in the consent banner.

Cookies

We use a small number of cookies for analytics and to remember your cookie choice. You can decline non-essential cookies with the banner and clear cookies at any time in your browser.

Advertising

We may display advertising through Google AdSense. Google and its partners may use cookies to serve ads based on prior visits to this or other websites. You can opt out of personalized advertising at Google Ads Settings.

Affiliate links

We link to products on Amazon and, when enrolled, on manufacturer sites using affiliate links. Clicking one may set cookies governed by the merchant's own privacy policy (for example Amazon's). We receive aggregate commission reporting only, never your purchase details.

Data we store

We do not run a database of visitors. If you email us, we keep the correspondence only as long as needed to respond. See also our Terms of Use and Disclaimer.
