Only you.
Your journal is not a feed. There is no public profile and no share link.
The coach sees a session so it can review that session. It does not use your journal to train. It never sees another trader’s journal.
We do not claim we cannot read it. A cloud model coaches you. That model sees the talk and cards you confirm for that session.
No exchange keys. You tell it what happened.
