Douyin, China’s version of TikTok, will limit the use of the platform for children to 40 minutes a day.

The rules will apply to users under 14, who have been authenticated using their real names, and who will be able to access it between 06:00 and 22:00.

Parent company Bytedance announced the app’s Youth Mode in a blog post, saying it is the first short-video company in the industry to have these limits.

It comes as China cracks down on teenagers’ use of technology.

According to Douyin’s user agreement, there is no minimum age on the platform, but under 18s must obtain the consent of a legal guardian. On sister app TikTok the minimum age is 13.

Popular Chinese messaging app WeChat, owned by tech giant Tencent, also has a youth model that limits young users’ access to games, as well as disabling the app’s payments function and the ability to find and broadcast a user’s physical location.

Earlier this month, Facebook-owned Instagram said it would start verifying the ages of its users in an effort to limit interactions between children and adult strangers on the app after UK legislators introduced new rules that oblige social media companies to take underage users’ “best interests” into account or face heavy fines.
