Keeping Your Information Private Online
Teaching children why personal information matters and how to keep it private when using the internet.
Your private information belongs to you — you get to choose who knows it.
When you are online, some information about you should stay private — just like you would not tell a stranger in the street where you live. This page helps you understand what information to keep to yourself and why it matters.
What Is Private Information?
Private information is anything that could help someone find you or pretend to be you. This includes your full name, your address, your school name, your phone number, your birthday and your passwords. Even things like a photo of you in your school uniform can tell someone where you go to school. Keep these things just for you and the grown-ups you trust.
Why Does It Matter?
Most people online are perfectly nice, but some people are not. If someone you do not know gets your private information, they could use it in ways you would not like. They might try to contact you, pretend to be you, or find out where you live. Keeping your information private helps keep you safe — it is like locking the front door of your house.
What to Do If Someone Asks
If someone online asks for your real name, where you live, what school you go to or any other private information, do not tell them. It does not matter how friendly they seem. You can say 'I am not allowed to share that' or just change the subject. If they keep asking, leave the conversation and tell a grown-up. A safe person will never pressure you to share private details.
