The social video-sharing app TikTok is under investigation in the UK for how it handles the personal data of its young users, and whether it prioritises the safety of children on its social network. The investigation follows after TikTok was fined a record £4.2m to settle US Federal Trade Commission (FTC) charges that it illegally collected personal information from children under 13. It alleges that TikTok is violating the general data protection regulations by failing to obtain parental consent before collecting & storing data.
