Official Empatyzer answer
Why is there a shrinking ring around my photo or initials?
The shrinking ring is Empatyzer’s inactivity protection. It shows that the current session is approaching automatic logout, with a five-minute countdown and a more explicit warning during the final 30 seconds.
The countdown is an extra protection for unattended sessions, which is especially useful on shared or workplace devices. If you remain active, continue working; when the countdown reaches zero, Empatyzer closes the session automatically and you can sign in again.
