TikTok is facing legal challenges from the former children's commissioner for England over how it uses children's data. The claim is filed on behalf of millions of UK and EU children who have used the video-sharing app. TikTok takes children's phone numbers, videos, exact location and biometric data, without sufficient warning, transparency or the necessary parental consent required by law. The children could each be owed thousands of pounds. TikTok said the case was without merit and would fight it. In 2019, TikTok was fined $5.7m by the Federal Trade Commission for mishandling children's data. Also, South Korea fined them because of how they collected children's data, and they were investigated by the UK's information commissioner's office because Musical.ly, which is incorporated into TikTok, was hosting content published by users aged under 13. 13.44% of British 8- to 12-year-olds use TikTok, despite its policies forbidding under-13s on the platform.
