>Riot/Mobile explicitly warns and prompts you to opt in if you try to discover contacts by email/phone number. It looks like this on Android
This is way better than the behavior of proprietary programs, but I'd much prefer if the program actively discouraged uploading private information. I can deny the permission myself, but there's not much I can do about other people's behavior, and with the way Riot currently works they are going to end up uploading my personal information.
A client that isn't even able to access contacts is one of my top wishes for Matrix right now. As soon as that appears I'm going to start recommending it to everyone over miniVector.
