Element is the name of the application (the client) and Matrix is the name of the network. A comparison to email may be helpful in understanding this; Element is the equivalent of Thunderbird, while Matrix is the equivalent of the Simple Mail Transfer Protocol (SMTP) that underlies email. Element/Matrix is not peer-to-peer; you have to trust the server. However, unlike Signal, the servers are not centralized, but rather federated - anyone can host their own. Unfortunately, the "federation model" has the trade-off that Matrix has [no metadata protection](https://web.archive.org/web/https://serpentsec.1337.cx/matrix): "Federated networks are naturally more vulnerable to metadata leaks than peer-to-peer or centralized networks". To minimize this, see Systemli's [notes on the safe use of the Matrix service](https://wiki.systemli.org/en/howto/matrix/privacy).

* "Disappearing messages" is not a feature yet, but it is coming. Message retention time can be set by the homeserver administrator, as mentioned above, and is in fact set on both of our recommended homeservers. * "Disappearing messages" is not a feature yet, but it is coming.

* One-to-one audio/video calls [are encrypted](https://matrix.org/faq/#are-voip-calls-encrypted%3F) and you can use them. Group audio/video calls are not encrypted, so don't use them. This will be fixed when [Element-call](https://github.com/vector-im/element-call) is stable. * One-to-one voice/video calls [are encrypted](https://matrix.org/faq/#are-voip-calls-encrypted%3F) and you can use them.

* The Matrix protocol itself theoretically supports [forward secrecy](/glossary#forward-secrecy), but it is [not currently supported in Element](https://github.com/vector-im/element-meta/issues/1296) because it breaks some aspects of the user experience such as key backups and shared message history. * The Matrix protocol itself theoretically supports [forward secrecy](/glossary#forward-secrecy), but it is [not currently supported in Element](https://github.com/vector-im/element-meta/issues/1296) because it breaks some aspects of the user experience such as key backups and shared message history.
