Hi,
I thought I'd flag this up - I've been talking to my 12 yr old about social media just this week & used a lot of the resources from the NSPCC to get across safety & privacy etc. They've now made an app to use which is pretty straight forwards & easy to use. I have limited use of social media so found it useful to find out more on apps/sites I don't use/haven't heard of etc.
If you search for NetAware on App Store you should find it.
