Circles - Kombucha Privacy
Unlike with other secure messaging apps, when you post something in Circles, there’s no implication that you’re expecting an immediate response. Instead, you just post whatever you want, whenever it’s convenient for you. Your friends will come along and see your post later, whenever it’s convenient for them. So in this way, it works more like a social network.
But unlike other social networks, your posts on Circles are encrypted so that they’re only readable by the people who you’ve invited and who have accepted admission into your circles. Even the service itself cannot read your messages or look at your pictures. There’s no creepy tracking or analytics running behind the scenes to sell you targeted ads. In this way, the security that you get with Circles is much more like that of an encrypted messenger app such as Signal, Wire, Threema, Element/Matrix, or WhatsApp (well, before the Facebook updates, anyway).
A group in the Circles app works pretty much like a group anywhere else. It has a well-defined set of members, and everyone who’s in the group is in the same group with everyone else. Everyone in the group can see everything posted in the group.
