- This page sends you to Google's own sign-in page. That visit is between you and Google. The counter at the foot of this page cannot see it, and does not pretend to.
- Google sends you back here with a signed statement of your email address and Google account identifier. This site asks for nothing more than that.
- This page hands that statement to Firebase, the Google service where pdf-iq accounts are kept, and gets back a sign-in for this browser. The counter shows that request: a third-party request, to identitytoolkit.googleapis.com. It is the same account the Android app uses.
What is kept, where, and what can read it is set out under If you sign in on the privacy page.
Signed in with Google, in this browser. Sign out and this browser forgets Pro until you sign in again. Signing out deletes this browser's copy of the sign-in; it does not sign you out of the Android app, or of Google.
