Abstract: In the digital age, mobile information technology is advancing rapidly and mobile applications have become an indispensable aspect of people’s professional and personal lives. In order to safeguard users’ personal information, the government mandates that mobile application companies should establish privacy policies. Nevertheless, due to various reasons, these policies have not fulfilled their intended functionality. This paper explores  the essence and characteristic of APP privacy policies, analyzing the challenges associated with acquiring user approval, processing the thirdparty SDK information collection, and anonymization technology. Additionally, by examining the practice of protecting personal information in Europe and America, we can pinpoint a course for combining public and private legal protection of personal information. To address the challenges present  in APP privacy policies, China ought to focus on cultivating corporate selfregulation, augmenting private remedies, and enhancing public law enforcement.

摘要： 数字时代下移动信息技术飞速发展，移动应用已经成为人们工作和生活中不可或缺的一部分.为保护用户个人信息，国家强制要求移动应用企业制定个人信息保护政策.然而，由于多种原因，个人信息保护政策并没有发挥预期的功能.探讨了APP个人信息保护政策的概念与性质，分析了APP在获取用户同意、第三方SDK信息收集处理以及匿名化技术等方面存在的问题.同时，通过研究欧美个人信息保护经验，可以找到个人信息公私法融合保护的路径.为解决APP个人信息保护政策中存在的问题，我国应从鼓励企业自律、强化私力救济和健全公力执法3方面入手.
