“By design, Signal does not have a record of your contacts, social graph, conversation list, location, user avatar, user profile name, group memberships, group titles, or group avatars,” Joshua Lund, a Signal developer wrote. “The end-to-end encrypted contents of every message and voice/video call are protected by keys that are entirely inaccessible to us. In most cases now we don’t even have access to who is messaging whom.”
Lund is referring to a recent law passed in Australia that will fine companies that do not comply with government demands for encrypted data up to AUS$10 million.
