You can use privacy settings in Windows 8 to allow programs
to access your location or your name and account picture. For
example, you might want a mapping app to have access to
your location so that it can display directions from where you
are to another location. Or, you might want to allow websites
you go to regularly to recognize you and greet you by name
when you visit.

If you or your child are concerned that an individual might
want to know where you are at any point in time, you are more at
risk if you carry a laptop or tablet device with you, and you might
consider blocking this access. However, for most people, this feature
simply adds convenience when using certain applications.
