New apps come out all the time and it's up to all of us, teachers, staff, students and parents to be aware of online dangers and do what we can to protect against them.
There are too many apps that could pose a risk to list here, so the safest approach is to use parental controls on your child's, phone, tablet or computer so that you can decide which apps can be downloaded. You can then look up each app online to understand it more and make an informed decision about whether it is safe for your child.
