TikTok has pulled out of operations in Hong Kong, according to a notice posted on its website.
From today, the app will no longer work in Hong Kong, after a new security law was imposed in the territory by China.
The company announced it would be making the move earlier this week.
The legislation has sparked fears for freedom of expression, and internet giants Google, Facebook and Twitter have put a hold on government requests for user data from Hong Kong authorities since it came into force.
"In light of recent events, we've decided to stop operations of the TikTok app in Hong Kong," the Chinese-owned firm said, becoming the first major social media platform to exit the city since the law was imposed last week.
