"Private conversation" mode

The ability to turn on "Private conversation" mode, which will let Kin not save anything outside of the session, not update mindmap etc once the mode is turned back off.

Some topics are things that should not be repeated. Things that one don't want Kin to remind you, refer back to or just know about for beyond the current conversation. The topic might still be extremely relevant and important to get out of your system, and this would be the solution to achieve that.
