Whether you are using a social networking site, internet dating or just chatting on a forum, the chances are you are putting personal information online. Once it's out there, you may not be able to control what happens to it. This could pose a risk to your privacy or even your personal safety.
So before you create a profile, post a picture or tell the online world what you're doing, think about how to make sure you're safe online.
The ICO has produced web pages about how people - particularly young people - can protect their personal details when using social networking sites.
You can also read our It’s your information leaflet entitled Using social networking sites safely.
