Privacy & Oversharing
How children can accidentally reveal too much personal information online, and practical steps to help them protect their privacy.
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's behaviour
- • 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.
