That is a Chinese level of data monitoring.
Although I don't see inside leg measurement and favourite sexual position, almost everything else is on there. And this is just for students?!
The more information you hold, the more of a honeypot you are. You should never store data you don't need. If you do genuinely need it, store it on a system that is not connected to the internet in any way, or better still, on paper in a file in a locked room.
You are painting a target on your back and on the back of everyone you hold data on if you demand that much data and then store it on a system connected to the internet.
It would be nice if folk in relevant positions read about this and audited the information they held, and the way they held it, erased anything they didn't need and moved the rest offline. But that never seems to happen. Maybe the fines need to be much larger, and levied upon the individuals responsible for data storage as well as the companies they work for.
