What you send
The domain and selected evidence window are sent to the Is It Blocked? Cloudflare Worker. As with any web request, Cloudflare processes connection metadata such as your IP address to deliver and protect the service.

We process the check, not a profile of you.
Is It Blocked? is designed as a small public lookup service. It does not use advertising trackers or build a profile from the domains you check.
What happens when you check a website
Only the information needed to run and protect the check is processed. The details below separate what you send, what is cached, and what the public pages do not collect.
What measurement services receive
Our server sends the website name, date window, and—when needed—a country code to the measurement services used for the report. Those requests come from our server, not directly from your browser.
What is cached
Successful domain reports may be temporarily cached at Cloudflare's edge. A small public hot-domain list may be cached in KV for up to 24 hours. Results are not attached to an account or user profile.
Normal page views
Background research references are not contacted during a normal page view or website check. The browser talks only to Is It Blocked? for report data.
Cookies and analytics
The public site does not set analytics, advertising, or preference cookies. The separate operator dashboard is not part of the public browsing experience.
Alerts page
The alerts page reads the same saved update as the world map. It does not create a subscription, collect an email address, or register a webhook.
Internal page data
The website uses same-origin, application-internal data requests to render reports and maps. They are not offered as a public integration service and do not create an API-user profile.
Service policies
Hosting and measurement services process limited request data under their own policies. Is It Blocked? does not add advertising identifiers or an account ID to those requests.
