Line app is extremely popular among kids and teens due to its wider variety of features and functionalities under one platform.

But is Line safe for kids?

Line app is not just an instant messaging and video calling app but also a social media app with timelines for sharing posts.

Your kid may already use Line app to chat with friends, make free video and voice calls, share posts on his timelines, and much more.

As parents, you should be aware of the risks involved in using Line app for kids. We will also illustrate how parents can keep their kids safe on Line app.

Is Line App Safe for Kids?

Unfortunately, Line app is not very safe for kids. There are various safety and security concerns for kids that parents should know about and take steps to avoid.

  • Cyberbullying
  • Kids and teens are prone to cyberbullying on any and all messaging and social media platforms, and Line app is no exception. Since kids can share posts on their timelines, friends and strangers can pass bullying comments.

    Besides, in group chats, cyberbullying is a common occurrence. This can demotivate kids, push them to depression, be socially isolated and force them to take life-threatening steps.

  • Exposure to Adult Contents
  • There is no dearth of adult content on Line app. Adult content is shared on timelines and sent through messages. Exposure to such mature content at such young age can divert the minds of the kids and bring about behavioral changes. There is a lack of Line chat security to block adult content for kids to stop them from coming across them.

  • Addictions
  • Apart from chatting with friends and sharing posts, Line app lets kids create cool stickers and funky avatars. In fact, Line Play is a social network platform to create awesome avatars and show them off. Besides, there are social games available that make the kids stay glued to Line app all the time.

    Naturally, an addiction grows in them, and they lose their concentrate on study and other essential activities. This can have adverse effects on their physical health, mental development, and behavior.

  • Child Predators
  • Child predators refer to those Line users who create fake profiles to lure kids into believing their fake personalities. Once they gain the trust of the targeted kids, they start to exploit the kids for sexual and monetary purposes.

    They may ask kids to share their intimate photos, threaten them to share their parents' financial details, and likewise. Therefore, parents need to monitor their kid's Line account regularly to identify child predators and report them immediately.

  • Information Leak
  • Line app is completely free to use and it earns revenue by sharing user data with third parties who use them for targeted advertisement. However, users have the right to allow or deny Line app from sharing their private data.

    But kids are not aware of this, and they give the app the permissions to share everything with third parties. Naturally, if those shared private data get breached by hackers, your kid's Line account and private messages and media files can be exposed.

3. Teach and Have Open Conversation with Kids

Parents should have a very friendly relationship with their kids from an early age. This encourages the kids to share everything in their lives with their parents.

Here are the main points parents should teach their kids to avoid the online dangers originating while using social media and messaging apps like Line.


Parents should make their kids aware of the dangers in the online world, especially Line messenger security concerns. Instead of strict orders, you should explain why talking to strangers should be avoided at all costs.

They should know how strangers scam people and hack their accounts and the aftereffects. Similarly, they should understand what cyberbullying is and what they should do when they are bullied.

Right and Wrong

You should teach your kids which things are appropriate and which things are inappropriate for their age. They should know which contents they can check and which contents are matured for them, and they should avoid at all costs.

You should teach them the steps to perform like blocking users on the Line app who are sending inappropriate texts and photos.

have conversation with kids


You should explain to your kid that you are giving him a smartphone so that he uses it responsibly and only for the tasks he is supposed to. You should disclose that you are going to monitor his phone activities remotely.

Explain how disappointed you would be if you find out that he used the phone or Line app irresponsibly for things he is not supposed to do like chatting with strangers, sending inappropriate texts and photos, not blocking strangers instantly, and likewise.

Open Conversation

Lastly, you can always encourage open conversations to find out what your kid did throughout the day starting from physical to online activities. Lack of proper conversations creates a gap in the parents-kids relationship.

When kids come across situations on Line app like cyberbullying, blackmailing, sexual harassment, they cannot confess their state of mind with their parents leading to depression and even suicide.


The answer to the question "Is Line safe for kids?" is no. The app itself is feature-rich and fun to use for kids. But there are safety and privacy concerns whereby kids could be subject to cyberbullying and exposed to adult content and child predators.

That is why a parental monitoring and control app is absolutely mandatory. We recommend you opt for KidsGuard Pro for Android or iOS as applicable.
