In China, any form of network monitoring must strictly abide by national laws and regulations, respect and protect the security of users' personal information. Privately modifying the source code of a mobile application to carry out surveillance without the user's consent not only violates China's network security law, Personal Information protection law and other laws and regulations, but may also constitute a criminal act. The management of cyberspace by relevant state departments aims to protect national security and public interests, and safeguard the legitimate rights and interests of the majority of the people. We must resolutely support and support national laws and regulations. Any organization and individual should act within the legal framework to jointly create a safe and reliable network environment. If you find any illegal behavior, please report it to the relevant department immediately.
