WhatsApp is the most widely used messaging app in the UK, offering text, voice, and video communication with end-to-end encryption. It also supports group chats, status updates, and file sharing. Whilst primarily used for practical family and friend communication, the lack of parental controls and content moderation means children need guidance.
Children use WhatsApp mainly for messaging friends and family, sharing photos and videos, and participating in group chats for school, sports clubs, and social groups. Group chats can become very active and sometimes involve bullying or the sharing of inappropriate content passed around peer groups.
Profile Photo Visibility
Location: Settings → Privacy → Profile Photo
Set to: My Contacts
Limits who can see your child's profile photo. Set to My Contacts to prevent strangers from viewing it.
Last Seen and Online
Location: Settings → Privacy → Last Seen and Online
Set to: My Contacts
Controls who can see when your child was last active. Reduces pressure to respond immediately and limits information available to strangers.
Group Invitations
Location: Settings → Privacy → Groups
Set to: My Contacts
Prevents unknown numbers from adding your child to group chats without their consent.
Disappearing Messages
Location: Settings → Privacy → Default Message Timer
Set to: Off (so conversations can be reviewed if needed)
Disappearing messages can prevent parents from reviewing conversations if a concern arises. Keeping this off is generally advisable.
Configure privacy settings together, ensuring profile photo, last seen, and groups are restricted to contacts only
Time: 5 minutes
Discuss what to do if they receive messages from unknown numbers or are added to unfamiliar group chats
Time: 10 minutes
Agree ground rules about what is appropriate to share in group chats, including forwarding content received from others
Time: 10 minutes
In immediate danger: call 999. For non-emergency police matters, call 101.

Myth: WhatsApp is private and encrypted, so it’s safe.
Fact: Encryption protects messages in transit but does nothing about who is in a group chat, disappearing messages, or the content shared within it. School group chats in particular are a common site of bullying and unwanted content.
Myth: Only people my child knows can message them.
Fact: Being added to group chats by acquaintances, and having ‘last seen’ or profile photo public, can expose a child to strangers. Set privacy to ‘My contacts’ and review group memberships.
Myth: Because WhatsApp is encrypted, nothing can ever be reported or proved.
Fact: Encryption stops outsiders reading messages in transit — it doesn't put behaviour beyond reach. Reporting a contact or group from inside the chat sends WhatsApp the most recent messages, screenshots still count as evidence, and schools act on what happens in class group chats all the time.
WhatsApp's minimum age in the UK is 13, so this age group is below it — even though class chats sometimes appear in the last years of primary school. Keep family messaging on your devices, and don't feel pressured just because 'everyone in the class' is in the group.
The pressure peaks when secondary school group chats form. If they're 13, set profile photo, 'last seen' and who can add them to groups to contacts only, switch on Silence Unknown Callers, and talk early about what to do when a group turns nasty: screenshot, leave, tell someone.
Group chats are where most trouble happens: forwarded images — sharing sexual images of under-18s is illegal even between peers — pile-ons, and disappearing messages used to say things without a trace. Agree they can show you anything from a chat without getting into trouble for being there.
Scams are the main hazard now: job offers from unknown numbers, impersonation messages, and account hijacks that start with 'can you send me that six-digit code?'. Two-step verification, and never sharing the verification code with anyone, covers most of it.
