University is about a lot more than the piece of paper you get at the end. If it’s of any real quality, and you are actually engaged with it, you’ll be learning from experts in your chosen field, amongst engaged and eager peers, whilst also being exposed to different viewpoints on everything from what to have for lunch through the latest innovations in your field, and adjacent ones, to the geopolitical state of the world. The people you meet, and the connections you form can, and often do, form the bedrock of your working life from then on.
All of that does make the assumption that you actively engage with university life and those around you. Make friends in different subjects, seek out your professors during office hours and talk to them about their interests, join clubs, do stupid, but ultimately harmless things.
It also assumes you are attending a ‘good’ university, rather than a profit driven degree mill, and those might be harder to find in some places than others.
Bear in mind that they already have your home address, as they sent the tablet to you, that address is geolocated, and anyone with a phobe passing near you will have enumerated any wifi networks and possibly bluetooth too and geolocated those.
They already know what devices are around you unless there’s not been a phone within range since you got them.
You were sent the tablet in order to be able to access the the app they provide. I strongly suspect that it is actually a loan, and they will want it back when you are finished with it. Given that, you shouldn’t even attempt to root it. Use it for what it is intended for, gain some benefit from that, hopefully get your massager, and return the tablet when you’re finished with it.
Unless you deliberately give them more information, there’s not much new they can gain about your environment from the tablet. What you do in the app is going to be much more valuable data to them as it’ll give them information about you and your health that they could not gain any other way.
