That was my first thought, but it’s actually a library for newsreader-type apps that lets a communication happen without exposing a whistleblower (it’s like a digital deaddrop).

I had a quick look and they’re going the things they need to like certificate pinning, so even corporate-level MITM wouldn’t be seeing any unusual traffic. I assume they’re also blocking access to the screen like banking apps do, which is more secure but annoying for normal users.
