The sites in the second group are a switch away so that installing Guardpup asks only for the best-known sites; your browser asks you once when you turn them on. Tested: we have seen Guardpup catch a made-up key on that site. Being tested: Guardpup runs there and we are confirming it by hand. If it ever can’t see a site’s message box, its toolbar icon says so.
How We Keep It Working
AI sites change their pages often. An automatic check visits the sites above, pastes a made-up key into the message box (it never sends anything) and confirms Guardpup catches it. If a site changes in a way Guardpup can't see, its toolbar icon shows a red ! on that site so you're never unknowingly unprotected, and we fix it as fast as we can. Pro gets the fix without waiting for an update; everyone else gets it in the next update.
