Viber is a free messaging app that lets you text, call, share photos and send video messages to people. There’s an emphasis on privacy. The app has end-to-end encryption and you can also have Secret Chats; after your message is read it will automatically delete itself from your contact’s phone.

Our overall rating for Viber


Viber has some privacy settings available that can help keep your child safe. These are automatically set up by default when a user is 16 and under.

However, the app is end-to-end encrypted meaning that only the sender and recipient can see the contents of a message. This makes it hard to report unwanted contact and inappropriate content.

Be aware that Viber also has a feature that lets you send messages that get deleted after a set period of time.

If you decide to let your child use the app, you should make sure to explore all the privacy settings available and agree some rules around who they’re allowed to talk to on the app. We wouldn't recommend children under 16 use this app.

Safety features

There are no parental controls or safety features available on Viber. It also doesn’t ask you to verify your age.

All communications are end-to-end encrypted which means that only the sender and recipient can see the contents of the message. This makes it harder to report unwanted contact and inappropriate behaviour.

Privacy & location

Viber is end-to-end encrypted meaning that only the sender and recipient can see the chat history. You need a mobile number to sign up for Viber, however, this is automatically hidden from other users.

There are a number of privacy settings available, such as turning off online status, not allowing the app to suggest friends, managing who can add you to groups. You can also decide who can see your profile picture. Viber says that these are set to default on accounts set up by under 16s so you should make sure your child signs up with the correct age.

You can also turn off location settings within the app to prevent your child from sharing their location.

Reporting & blocking

The reporting and blocking features on Viber are easy to find. However, they vary depending on which communication feature you’re using. You should take the time to explore the different features with your child so they know what to do if they ever need to user them.

It may also be useful to have a read through the simple Viber Public Content Policy so that you and your child know what is appropriate or not on the app.


We didn’t come across anything inappropriate while exploring Viber. However, as the app has been created for users to interact with each other there is no way to control what gets shared. This means your child could be sent something inappropriate or that upsets them by another contact.

Viber also don’t use any moderation tools to stop certain content from being shared. This means that inappropriate content only gets deleted when it gets reported.

Check the privacy settings

Viber states that for accounts set up by under 16s all privacy features are turned on by default and cannot be turned off until the child is 16. Check your child’s account to make sure they’re switched on.

Top tips for staying safe

Sitting down with your child and exploring Viber together is a great way for you to learn more about the app and how your child might want to use it. It will also give you an opportunity to discuss ways they can keep safe and agree rules around who they can talk to.

Help your child think about what they share online and who sees it. Compare it to what they would be happy to share offline.

Use examples that are easy for them to understand: “You shouldn't give your number to somebody you don't know on the street. Is somebody online you don't know any different?”

Listen to their answers. And be positive and encouraging.

Remind them that they shouldn’t share private things, such as:

  • personal information, like names, emails, phone numbers, location and school names
  • other people's personal information
  • links to join private group chats
  • photos of themselves
  • photos of their body, such as sexual photos or videos.

Your child might receive something upsetting or negative on Viber. If this happens, they might want to block another user.

Viber has specific guidance on how to block a contact.

And remember to let your child know that they can always talk to you about worrying things they see online. 

Explain that you understand the internet is a great place to play, create, learn and connect. But remind them they can talk to you if anything upsets or worries them.

Reassure them that you won’t overreact – you’re just looking out for them.

It’s important to remind your child that they can talk you, another adult they trust, like a teacher, or Childline about anything they see online.
