European Union regulators have issued a warning to TikTok amid concerns that the youth-aimed app has violated children's data protection laws. TikTok has been given one month to respond to the complaint and engage with authorities on a resolution. "Areas of specific concern include hidden marketing, aggressive advertising techniques targeted at children, and certain contractual terms in TikTok's policies that could be considered misleading and confusing for consumers," according to a release by the European Commission, the EU's executive branch. "It is prohibited to target children and minors with disguised advertising such as banners in videos," added Justice Commissioner Didier Reynders.
