The U.S. Department of Justice (DOJ) accused TikTok of gathering Americans’ data on sensitive content and censored topics. The department said TikTok’s Chinese owner, ByteDance, had TikTok gather information about users’ views on social issues — including gun control, abortion and religion.

In a document filed Friday, July 26, the DOJ said an internal web system called Lark — which allows TikTok employees to communicate directly with ByteDance — was used to gather the information. DOJ lawyers said the information was stored on Chinese servers and accessible by ByteDance employees in China.
