Also the only way that they can track you from an iPad is if they have created the iCloud account and it's been put onto the iPad. This way they can track exactly where the iPad is. They can also wipe all of the data hands free. The one thing they can't do is look at what's on your iPad. Also if you're using it on their wifi they can't track who's doing what, names don't appear on wifi traffic.
