TikTok has been fined £12.7m for failing to protect the privacy of children, the UK's data watchdog has said.
Ednews reports citing BBC that an investigation conducted by the Information Commissioner's Office (ICO) found the video-sharing app breached data protection law.
It says the breaches happened between May 2018 and July 2020.
TikTok says it disagrees with the ICO's decision.
It is one of the largest fines the regulator has issued. However, it is still half of what the ICO threatened last year.
In September, the watchdog issued TikTok with a "notice of intent" - a precursor to handing down a potential fine.
The ICO estimates that TikTok allowed up to 1.4 million UK children under 13 to use its platform in 2020, despite its own rules not allowing children that age to create an account.
UK data protection law says that platforms that use personal data when offering information to children under 13 must have parental consent.
