[email protected] - Here are a few interesting details about the maximally privacy-friendly protocol design:

Everything related to synchronization between devices is completely end-to-end encrypted

Message recipients do not know from which device a message was sent

The Mediator Server of a device group does not know the corresponding Threema ID

The Chat Server only sees the IP address of the Mediator Server, but not the IP address of the end devices
