A European consumer rights group has filed a complaint that accused the popular short-video app TikTok of violating the rights of its users and exposing underage viewers to inappropriate material.
The complaint, filed to the European Commission Wednesday, jeopardizes TikTok’s standing in the 27-nation market, which supplies roughly one-seventh of the ByteDance Ltd.-owned app’s total users worldwide. It also puts the company at risk of being fined as much as 4% of its global annual sales under EU data protection rules.
