gpg-agent keeps running after session logout if the user chose to not launch GNOME services on session startup (Settings Manager > Session and Startup > Advanced).

thad@local:~$ loginctl list-sessions
   SESSION UID USER SEAT
       c17 1001 bob seat0
       c19 1000 thad seat0

2 sessions listed.

$ ps -u bob
  PID TTY TIME CMD
16903 ? 00:00:00 gpg-agent

$ ps aux | grep bob
bob 16903 0.0 0.0 6464 332 ? Ss 17:10 0:00 /usr/bin/gpg-agent --sh --daemon --write-env-file /home/bob/.cache/gpg-agent-info
