XMPP (Extensible Messaging Presence Protocol) is a decentralized model of network to facilitate instant messaging and collaboration. Decentralize means there is no central server that has access to your data. The communication is directly between the end-points.
Some of us might call it an “old school” tech probably because the XMPP clients usually have a very bad user experience or simply just because it takes time to get used to (or set it up). That’s when Dino comes to the rescue as a modern XMPP client to provide a clean and snappy user experience without compromising your privacy.
