HONG KONG—In the latest move to curb screen time for younger Chinese users, ByteDance Ltd., the maker of the hit short-video mobile app TikTok, said that it would restrict access to Douyin, the Chinese version of the app, to 40 minutes a day for users under 14 years old.
Douyin’s “youth mode,” which follows the imposition of new limits on younger Chinese users’ access to online videogames, will restrict under-14s to using the app between 6 a.m. and 10 p.m. The app will be inaccessible to all users in that age group outside of those hours.
