The Conversation That Never Happened: Chitchatter
Any messenger has a downside of convenience. While the correspondence is synchronized between devices, a copy of it remains somewhere on the company’s servers - sometimes encrypted, sometimes not so much, but almost always living much longer than the conversation itself. This is the norm for work chats, but there are situations when you want exactly the opposite: to talk, exchange a file - and after that there is nothing left at all, on anyone’s servers, or even in the interlocutor’s history.
