Justice Department sues TikTok, alleging data collection from minors

The Department of Justice (DOJ) has accused TikTok of violating a law that protects children's online privacy and breaching a previous settlement with another federal agency. The lawsuit, filed with the Federal Trade Commission (FTC) in California, alleges that TikTok and its parent company, ByteDance, failed to obtain parental consent before collecting personal information from children under 13. The previous settlement involved Musically, which merged with TikTok after being acquired by ByteDance. TikTok is also accused of sharing children's data with Facebook and an analytics company called Apps Flyer.
