Yusi encrypted chat software is one of the few encryption software in China. End-to-end encryption is one of the internationally recognized highly confidential data transmission technologies, which is used in users' chat messages to ensure the privacy and security of information. This encryption method ensures that the chat content is only stored in your and your friends' terminal devices, and only you can view it. Therefore, there will be no eavesdropping and monitoring of user privacy by third parties such as developers, operators and contractors.

At the same time, as a secure and private chat software, Yusi app has many other functions to ensure the privacy of the chat, such as screen capture reminder (any party in the chat takes a screen capture, and the system automatically intercepts the reminder), burn after reading, and two-way withdrawal (the chat records of both parties cannot be recovered for unlimited time).
