WhatsApp is a free instant messaging app with up to 2 billion active monthly users worldwide. Using an internet connection, the app allows users to send messages to contacts added to their WhatsApp account either individually or in group chats. Users must verify their account with a standard mobile phone number to start using the app. There are no parental controls available through the app, but there are a range of privacy settings that users can change to help control who they contact and what information is shared.

WhatsApp now sits alongside Instagram, Facebook and Messenger under the parent company Meta.  Meta replaces Facebook as the leading company/brand in this group, and the Meta branding is likely to become increasingly visible on all of these apps.  


The minimum age restriction for WhatsApp users is 16, however it does not have any rigorous age verification methods.

WhatsApp is a messaging app for those looking for convenience as well as enhanced privacy and security. It is especially convenient for users to connect with friends as it syncs to your phone contacts and connects you to their WhatsApp profiles.  The app is incredibly user friendly and the ability to set up individual and group chats is appealing for teens. WhatsApp groups are extremely popular with young people, especially within school communities for year groups, classes and individual friendship groups. However, some young people feel that lots of bullying occurs on the platform within larger group chats, with participants sharing personal content and screen shots of other conversations.


  • This allows users to share text, photos and video updates with their contacts that disappears after 24 hours. To send and receive status updates, users need their contact’s number saved in their phone.

  • The main feature of WhatsApp is the ability to have individual or group chats with contacts saved in your phone.

  • This is the user who sets up a group chat. This is the only user who can add or remove participants and change or add additional group administrators. Individual users can leave a group without needing the ‘Group admin’ to intervene.

  • Providing you have an internet connection, users can call a contact on WhatsApp. This can be either an audio or video call with an individual or groups of up to 8 people.

  • WhatsApp allows users to share photos and videos with their contacts. This can be either through access to the camera or by sharing photos and videos from the camera roll on the phone.

  • Instead of sending text messages, users can record voice messages by holding down the microphone icon in the chat function.

  • This term refers to the small cartoon faces with various expressions users can send to each other. The list of Emoji options now includes people, buildings, animals, foods, symbols and more.

  • As well as sending text and emojis, users can also send Gifs to their contacts. A Gif is an animated image without sound.

  • This allows users to send an image to be seen once. Once viewed it is automatically deleted from both devices.  

  • The blue double tick that appears next to a message once the recipient has read it.

  • This tells other users the last time you used WhatsApp or if you’re online.


Like other messaging apps, a lot of personal stories, messages and pictures are shared by users on WhatsApp - these are not moderated. The best way to manage the content your child is exposed to is to ensure they are only connecting with people they know, rather than strangers. Ensure the privacy settings have been set to ‘My contacts only’, rather than ‘Everyone’. It is also possible your child may stumble across inappropriate content in the form of bad language or mature content in their messages. By restricting who your child can access on the platform, your child is less likely to experience language or behaviour that is not suitable for their age. However, it should be acknowledged that your child may still be exposed to inappropriate content by their known contacts.

As WhatsApp has an age restriction of 16, it does not include any real parental control settings. Like many other social media apps, some children sign up to WhatsApp when they are under the suggested age limit. This is a risk as WhatsApp defaults to ‘Everyone’ on many of its privacy features, which means all users on the platform can view personal information, chat and share images without any filters in place. Speak to your child about the risks of connecting with strangers and explain the importance of not sharing any personal or identifiable information on their profile or within chats. Remind them to tell you if they have been asked more personal questions or to chat privately in a way that makes them feel uncomfortable. Changing the privacy settings to sharing only with ‘My contacts’ is recommended. It is recommended that younger users should also change their group privacy settings to ‘My contacts’, to avoid unknown contacts from adding them to group chats.

If your child has their own WhatsApp account, it is important for you and them to be aware of what they share and the impact this will have on their digital footprint. Ensure your child knows it can be difficult to keep ownership of any content once it has been shared online, as content can easily be copied and reposted without their knowledge and can then become difficult to remove from the internet.

The ‘View once’ feature on WhatsApp could pose a risk to some users. This feature may be conducive of bullying behaviours, with some users feeling they are not culpable if the message can’t be viewed again. Remind your child that the receiver can easily screen shot the message before it disappears, so they should be careful about any message they send or share.

One of the features of WhatsApp is its use of end-to-end encryption. This means that only those with access to the phones of the sender and receiver of a message can access them - not even WhatsApp itself can gain access to messages. Whilst this is an attractive security feature for many adults, it has caused problems for law enforcement when trying to access the message records of victims and suspects involved in child exploitation cases. Changing the privacy settings to sharing only with ‘My Contacts’ is once again recommended.

WhatsApp users should be aware of how ‘Read receipts’ and ‘Last seen’ are designed to keep users on the platform for as long as possible. Speak to your child about how platforms are designed to be compulsive in this way and encourage them to disable these features to give them a break from constant messaging.


  • All accounts default to a setting where any WhatsApp user can see your ‘Read receipts’, ‘Last seen’, ‘About’ and profile photo. WhatsApp gives users the option to choose who they share their information with by selecting one of the following options: ‘Everyone’, ‘My contacts’, ‘My contacts except’ and ‘Nobody’. The app also requires background location for the ‘Live location’ feature, which can be managed on your phone’s settings.

    • Go to the user you want to report either by searching or scrolling through your chat list.
    • Tap on their name at the top of the page.

  • To help limit the pressure for young people to be online and respond to messages straight away, WhatsApp has some settings to help manage usage. ‘Read receipts’ tell other users when you have read a message and ‘Last seen’ refers to the last time a contact used WhatsApp.

    To turn off ‘Read receipts’:

    • Open the app and selectSettings’ at the bottom of the page.
    • Select ‘Account’ and tap on ‘Privacy’.
    • Scroll down to ‘Read receipts’ and toggle the button off.

    To turn off ‘Last seen’:

    • Open the app and selectSettings’ at the bottom of the page.
    • Select ‘Account’ and tap on ‘Privacy’.
    • Tap on the ‘Last seen’option and select ‘Nobody’.

End-to-end encryption can make the app particularly appealing to those who wish to communicate securely. However, this feature could be used by adults who want to develop a relationship with a child to potentially harm or abuse them. Try to make sure your child is only using WhatsApp to communicate with other users that they know and trust.
