How the Blocked From Here screensaver works

The saver reads the source described above and draws it on a canvas — no account, no tracking.

Web-connectivity anomalies measured by OONI volunteers on their own connections, key-less. A map of two things at once: where interference happens, and where people have installed a probe. A broken site looks much the same from outside.

It refreshes on a schedule, so what you see stays current.

Colours and any options can be changed in settings; nothing is stored beyond your own browser.
