TikTok: App introduces screen-time limits for under-18s
TikTok has introduced a new daily screen-time limit for people under 18.
This means that teenagers will be only allowed to use the app for an hour a day - and if they go over this limit they will have to enter a password.
However, people will be able to opt out, which means not everyone will have to do it if they don't want to.

TikTok's screen-time plan
Tiktok currently does not have any limits for users' screen-time. However, last year the app introduced a screen break feature.
After a long time scrolling, you would get a screen pop up that warned you to take a break. It was aimed to help people control how much time they spent on the app in one go.
Lots of smartphones have features where you can check how much time you're spending on certain apps, and you can often set limits, but TikTok's new feature is aimed specifically at under-18s.
If they use the feature, it stops under-18s can't spend more than an hour a day on the app.
However, users can choose not to use the screen-time limits if they want to, and can override the screen break with a code if they choose to.
If a teenager uses the app with this feature turned off, they will still get a notification from TikTok encouraging them to use parental controls.

Does TikTok have parental controls?
Currently, parents or guardians can use the Family Pairing option on TikTok, which means they can set their own screen-time limits.
It also means anyone singed up to it can see how the app is used, and how often.
As well as this, Family Pairing users can decide whether teenagers can search for videos, message people, or make sure the things they are seeing on TikTok are safe.
What is being said about it?
TikTok's rules say no-one under 13 should be using the app, 44% of eight to 12-year-olds in the UK use the app.
Cormac Keenan is in charge of trust and safety at TikTok. He said they spoke to tech and children's health experts to choose the one hour limit.
However, others think time limits are not enough and that the company needs to do more to prevent children seeing inappropriate and harmful content.
