TikTok will need to reach deep into its pockets after the Irish data watchdog hit the social video platform with a massive 530 million euro ($600 million) fine on Friday. Ireland's Data Protection Commission charged the company with violating Europe's strict privacy laws by not doing enough to ensure that anyone's data transferred to China is properly protected from government surveillance.

Ireland’s data privacy watchdog fined the social-video app for failing to guarantee that user data sent to China was protected from government surveillance.

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.
