Privacy & Oversharing
How children can accidentally reveal too much personal information online, and practical steps to help them protect their privacy.
Privacy is the practice of a child posting too much personal information online, such as their location, school, or routines, which strangers can use to identify or target them.
What is this?
Children often share personal details online without realising the potential consequences. Information such as their full name, school, location, daily routines, and family details can be pieced together by anyone viewing their profiles. Oversharing creates opportunities for identity theft, grooming, and real-world safety risks.
How it works
Children may reveal personal information through social media bios, public posts, geotagged photos, or casual conversations in games and group chats. Even seemingly harmless details — a school uniform in a selfie, a check-in at a local venue — can help someone build a detailed picture of a child's life and whereabouts.
Warning signs
In your child
- • Posting photos or stories that include identifiable locations, school names, or home details
- • Sharing personal information freely with people they have only met online
- • Showing little concern or awareness when asked about who can see their posts
On their device
- • Public social media profiles with full name, school, and location visible
- • Geotagging enabled on the camera and social media apps
- • Friend or follower lists containing a large number of unknown contacts
Prevention steps
Review privacy settings together
Sit with your child and go through the privacy settings on every app and platform they use. Set profiles to private and disable location tagging on photos.
Teach the 'billboard test'
Ask your child: 'Would you be happy if this was displayed on a billboard outside your school?' If not, it probably should not be posted online.
Agree on what is never shared online
Create a simple list of information that is always kept private: home address, phone number, school name, daily routines, and holiday plans.
What to do if it happens
- 1Calmly help your child remove or edit any posts that contain too much personal information.
- 2Change passwords and review account security if personal details may have been compromised.
- 3Use it as a learning opportunity rather than a punishment — discuss what could be shared more safely in future.

Myths & facts
Myth: My child has nothing to hide, so oversharing isn't really a risk.
Fact: The risk isn't secrets — it's ordinary details. A school uniform in a photo, a tagged location, a birthday and a pet's name together build a picture that strangers can use to find, impersonate or manipulate a child.
Myth: If they delete a post, or use disappearing messages, it's gone.
Fact: Anything on a screen can be screenshotted, recorded or forwarded before it disappears, and platforms may keep copies. The safer working assumption is that anything shared could turn out to be permanent and public.
Myth: Oversharing only matters if strangers see it.
Fact: Friendships change, and something shared with a trusted friend at 12 can be spread around a year group at 14. It's also worth looking at your own posting — family accounts often reveal school, location and routines more clearly than the child's own profile does.
Age by age
- 8-10
Teach personal information as a category — full name, school, address, passwords, where they are right now — and practise spotting when a game or app asks for it. Keep profiles and gamertags free of real names.
- 11-13
Sit down together and look at their profile the way a stranger would: what could someone work out from the photos, tags and comments? Turn off location tagging and prune followers they don't actually know.
- 14-16
Talk about their digital footprint following them to sixth form, jobs and beyond, and about consent — not posting photos or stories about friends without asking. Be clear about the law on nude images of under-18s, and that they can always come to you first.
- 17-plus
Encourage a periodic self-audit: old posts, tagged photos, and what a search for their name turns up. Discuss how shared details feed scams and account takeovers, and the value of keeping some things offline.
