# What is ChatCube?
ChatCube is a mobile encrypted messaging tool consisting of a mini server and APP. Any information and files sent and received will be end-to-end encrypted!
The Cube server is plug-and-play, can be placed at home or in the office, and can be used within 2 minutes after plugging into the network cable.
The Cube owner needs to hold a server while other users only need to install the ChatCube app. When you send and receive messages, all messages and files will be strictly encrypted and no one can steal them. Moreover, your chat data will neither remain on social platforms nor be manipulated by Big-Data-Analysis.
