As little as possible, and never sold or profiled.
A tool that grades other sites on privacy should set the example itself. So: privacy-friendly analytics, no accounts, and as little data as possible.
Privacy-friendly, self-hosted analytics
We do count page views, but with self-hosted Plausible on our own server, not a service like Google Analytics. It sets no cookies, collects no personal data and never follows you across sites, so it needs no consent banner. It is proof that you can understand your traffic without tracking people. The only cookie here is a functional language cookie (Dutch or English).
What we do process
Only your IP address, held briefly in memory, to limit too many checks in a short time. It is not stored and not tied to a profile. There are no accounts.
Security reports
If this site's own security policy is ever violated, your browser sends a short technical report to our error monitor (in the EU) so we notice. That fires only on such a rare event and carries no personal data beyond what any web request already includes.
The site you enter
We fetch it to inspect and grade it. We do not keep its content, unless you freeze a report yourself; then we store the URL and the result so the snapshot stays shareable.
Nothing sold, nothing profiled
We sell no data, build no profiles and show no ads. What you check stays yours.
