The US Department of Justice sued TikTok today, accusing the short-video platform of illegally collecting data on millions of kids and demanding a permanent injunction "to put an end to TikTok’s unlawful massive-scale invasions of children’s privacy."

The DOJ said that TikTok had violated the Children’s Online Privacy Protection Act of 1998 (COPPA) and the Children’s Online Privacy Protection Rule (COPPA Rule), claiming that TikTok allowed kids "to create and access accounts without their parents’ knowledge or consent," collected "data from those children," and failed to "comply with parents’ requests to delete their children’s accounts and information."

The COPPA Rule requires TikTok to prove that it does not target kids as its primary audience, the DOJ said, and TikTok claims to satisfy that "by requiring users creating accounts to report their birthdates."
