Isn't the whole point of disappearing/delete-able messages that you leave the meaning in your recipient's brain but not on your phones? So if a third party later tries to read your chat logs they won't see anything (sensitive). I think it's assumed that your recipient is not malicious. I swear at some point there was a warning saying that if you enable disappearing messages it wouldn't prevent your recipient (or you) from simply taking a screenshot of the messages.
