An American student who transmitted her data to China is a new issue linking the application of Tik Tok with the Beijing government

A California university student has accused the popular video-sharing app Tik Tok in a lawsuit of transferring its user data to servers in China, despite company assurances that it does not store personal data there.

The new prosecution may deepen the legal problems faced by the US-owned application of Chinese byte Dance Technology, which operates entirely outside China, and has developed a large user base, especially among American teens.

The company is already facing a US government national security investigation over concerns about data storage and possible censorship of sensitive political content.

The lawsuit, filed in the US District Court for the Northern District of California, alleges that Tek Tok has transferred the student's statement, Misty Hong, to servers in China.

Tik Tok did not immediately respond to a request for comment on the allegations, but confirms that it stores all US user data in the United States with backup copies in Singapore.

The documents identify the alleged university student and resident of Palo Alto, California, who downloaded the TikTok app in March or April 2019 but never created an account.After months, she claims, she discovered that TikTok had created an account without her knowledge and issued A file of information about it, including biometric information from videos you’ve created but never published.

According to the lawsuit, Tik Tok recently transferred user data to two servers in China, Bigley (bugly.qq.com) and Wyoming (umeng.com), including information about the user's device and any websites visited.

Tencent (China's largest mobile phone software company) owns the Bigley server and also owns WeChat's social network, while Yuming is part of the Chinese e-commerce giant Alibaba Group.

The lawsuit also mentions that the source code from the Chinese technology giant Baidu is integrated into the Tech Talk app, as well as the code from Igexin, a Chinese advertising service discovered by security researchers in 2017 and used by developers to install spyware on a user's phone.

No legal evidence of data transfer or the presence of Baidu or iJexen source code was provided in the application. Hong and her legal representatives were not immediately available for comment.
