LONDON — A European Union privacy watchdog fined TikTok 530 million euros ($600 million) on Friday after a four-year investigation found that the video sharing app's data transfers to China put users at risk of spying, in breach of strict EU data privacy rules.
Ireland's Data Protection Commission also sanctioned TikTok for not being transparent with users about where their personal data was being sent and ordered the company to comply with the rules within six months.
The Irish national watchdog serves as TikTok's lead data privacy regulator in the 27-nation EU because the company's European headquarters is based in Dublin.
''TikTok failed to verify, guarantee and demonstrate that the personal data of (European) users, remotely accessed by staff in China, was afforded a level of protection essentially equivalent to that guaranteed within the EU,'' Deputy Commissioner Graham Doyle said in a statement.
TikTok said it disagreed with the decision and plans to appeal.
The company said in a blog post that the decision focuses on a ''select period'' ending in May 2023, before it embarked on a data localization project called Project Clover that involved building three data centers in Europe.
''The facts are that Project Clover has some of the most stringent data protections anywhere in the industry, including unprecedented independent oversight by NCC Group, a leading European cybersecurity firm," said Christine Grahn, TikTok's European head of public policy and government relations. ''The decision fails to fully consider these considerable data security measures.''
TikTok, whose parent company ByteDance is based in China, has been under scrutiny in Europe over how it handles personal information of its users amid concerns from Western officials that it poses a security risk over user data sent to China. In 2023, the Irish watchdog also fined the company hundreds of millions of euros in a separate child privacy investigation.
