Top tips for staying safe online:

Don’t post any personal information online – like your address, email address or mobile number
Think carefully before posting pictures or videos of yourself. Once you’ve put a picture of yourself online most people can see it and may be able to download it, it’s not just yours anymore
Keep your privacy settings as high as possible
Never give out your passwords
Don’t befriend people you don’t know
Don’t meet up with people you’ve met online. Speak to your parent or carer about people suggesting you do
Remember that not everyone online is who they say they are
Think carefully about what you say before you post something online
Respect other people’s views, even if you don’t agree with someone else’s views doesn’t mean you need to be rude
If you see something online that makes you feel uncomfortable, unsafe or worried: leave the website, turn off your computer if you want to and tell a trusted adult immediately.
