As teens spend more time on social media apps, parents,and advocacy groups have urged tech companies to focus more heavily on issues such as cyberbullying, child exploitation and mental health. was also sued in April over allegations the video app illegally collects and use children's data, claims the company said "lack merit."
TikTok said users who are 16 or 17 years old will have their direct messages set to "No one" by default when they first join TikTok. Currently, TikTok's direct messaging settings are set to "Friends" by default, meaning that users can receive messages from followers they follow back. Teenagers who've never used direct messaging will also receive a prompt asking them to review their privacy settings. TikTok already disables messaging for users under 16 years old.
The company is also limiting when teens receive push notifications that could entice them to spend more time on TikTok. Users between the ages of 13 to 15 won't receive push notifications after 9 p.m. Teens who are 16 or 17 will have push notifications disabled at 10 p.m.
TikTok is also introducing new pop-ups meant to make teenagers more aware of the app's privacy settings. When teens under 16 are about to publish their first video, they'll also see a pop-up that asks who they want to let watch the video.
Teens 16 to 17 will also see a pop-up if they turn on video downloads. The prompt will tell the users that enabling this option means other people will be able to download their videos and share them on other platforms. Video downloads are disabled for account holders under 16.
The new controlsannounced come after the company in January made accounts for people under 16 private by default.
"Our priority is to ensure teens on TikTok have a safe and age-appropriate experience as they create and share on our platform," said TikTok's global minor-safety policy lead, Tracy Elizabeth.
Other social media companies, including, have also rolled out more safety features aimed at protecting teenagers.
