Get the lowdown on what’s OK to post on socials and what you should keep to yourself.

It might seem obvious not to share your bank details online – but surely a pic of you in your school uniform is harmless? How about checking in online when you’re at your favourite local cafe with mates?

So, what’s OK to share?

Some of the following might help narrow down your identity, but probably won’t be enough to identify you:

  • Your full name
  • GIFs
  • Your pet’s name
  • Memes
  • Your nickname
  • The weather
  • Your sports and hobbies

  • Holiday plans
  • Check-in location
  • Email address
  • Your school
  • Birthday
  • Photos
  • Mobile number
  • Geotagged photos
  • Pic of concert tickets

Things you should never share

Keep these deets top secret – you don’t want them getting into the wrong hands:

  • Login and password details
  • Banking details
  • Pic of your new driver’s licence
  • Home address
  • Banking PIN
