 There are several network architectures commonly used to relay messages between users. These networks can provide different different privacy guarantees, which is why it's worth considering your [threat model](https://en.wikipedia.org/wiki/Threat_model) when making a decision about which app to use.

 A messenger using [anonymous routing](https://doi.org/10.1007/978-1-4419-5906-5_628) hides either the identity of the sender, the receiver, or evidence that they have been communicating. Ideally, a messenger should hide all three.
