Turning training off doesn't rewind what already happened

Being able to change a setting is useful. It doesn't necessarily mean you can undo everything that happened while it was on. Anthropic's consumer-policy FAQ says switching training off excludes stored chats from future training runs. But it says data can remain in training already underway and in models already trained. Deleting chats also excludes them from future training. That difference should be impossible to miss. People may hear “you can change your mind” and assume the whole thing is reversible. The actual promise is narrower, and customers deserve to understand it before opting in. How would you explain this limitation in one sentence on the consent screen?
