Statable GDPR Checker door Statable

See what a site sends before anyone agrees to anything.

Open the sidebar on any page and reload it. The checker watches from the first millisecond of the page load and reports what happened before the cookie banner was answered: which third-party trackers fired, which cookies were stored, and which companies received the visitor's IP address and page URL.

What you get

• A verdict with the evidence behind it — every finding names the vendor, the request and when it happened, not a score out of ten.
• What to do about it. Each finding comes with a fix, free options first: how to gate a tag behind consent, how to self-host fonts, which setting to turn on in the consent tool you already pay for.
• Cookies set before consent, with their attributes — persistence and SameSite are the difference between a load balancer's session cookie and a cross-site identifier.
• A clean check in a private window, so a consent you granted on an earlier visit does not quietly make the site look better than it is.

How it decides

Detection runs on a hand-written signature set — every rule authored from public vendor documentation and our own measurements of thousands of European sites. No third-party tracker lists are imported. The panel shows the ruleset version and signature count, so any verdict can be traced to the rules that produced it.

A tracker that waits for consent is working correctly and is reported as such. A page the checker could not measure is reported as not measured — never as clean. Absence needs a complete measurement; presence does not.

Your privacy

The extension makes no network requests. Not to us, not to anyone. There is nothing to send because every measurement is computed in your browser and discarded when the tab closes. No accounts, no storage, no analytics.

Firefox's permission summary says "Access your data for all websites" — that is what the webRequest permission needs in order to observe what a page loads. Reading requests is the measurement.

This is a technical measurement, not legal advice. It reports what a page did. Whether that is lawful depends on context this tool cannot see.
