Chinese-owned short video-sharing app TikTok on Thursday announced stricter privacy controls for teenagers.

A pop-up will appear asking teenagers under the age of 16 to choose who can watch their videos before they can post them. TikTok said the changes, targeted at users aged 13 to 17 years old, will be rolled out globally over the coming months.

“The process of making a TikTok is fun and creative – choosing music, picking effects, and getting the transitions right – but it is just as important to choose who that video will be shared with,” TikTok’s head of child safety public policy, Alexandra Evans, and its global head of privacy, Aruna Sharma, said in a blogpost.
