When my kids went away to college it was something of a relief. They were on their own. I would not know where they were, who they were with, how late they were staying out, or any of the stuff I was much more aware of when they were living at home.

I never GPS tracked them even when they were younger. They got inexpensive Android smartphones in 8th grade, with a talk about what to watch out for. I didn't read their email or text messages, I didn't lurk on their school website checking grades every day. If a teacher or administrator emailed me, I'd deal with that, but otherwise I tried to let them learn to run their lives. They made some mistakes. That's how you grow.
