The Irish regulator found the video-sharing app did not 'address potential access by Chinese authorities to European Economic Area (EEA) personal data under Chinese anti-terrorism, counter-espionage and other laws.

Irish investigators said TikTok did not protect the data of users in the European Union, improperly transferring some of it to China. TikTok said it would appeal.

European Union privacy watchdogs have fined TikTok 530 million euros ($600 million). They say a four-year investigation found that the video sharing app’s data transfers to China breached strict data privacy rules.
