Signing in stores a token on your device to keep you signed in. Social sign-in also uses a five-minute cookie to check that the login return matches the browser that started it. If you switch between the light and dark theme we remember that too, because you asked for it. We use no advertising trackers and no analytics cookies. We do count visits in a pseudonymous way, with our own counter and a self-hosted Umami, and Do Not Track or Global Privacy Control turns that off. Your answer here is saved so we do not ask again; at the moment it does not change what the site does.
