I've noticed that my school Google account's Chrome was still active on another desktop while I was home watching YouTube. Is there a way this would let my school see what I'm doing on my personal browsers, or send any of my data back to them?

A quick tip: if you want to keep things private, turn off YouTube history on your Google account page. That way, they shouldn't be able to see your viewing habits.
It really depends on the operating system you're on. If you're using ChromeOS or Android and your school account is signed in with sync turned on, it can share quite a bit of data like bookmarks, history, and even passwords across devices. Plus, it tracks more than just your browsing, including app usage and interactions with Google services. You can see this data in your Google My Activity.
If you're on Mac or Windows, it's mostly limited to what you do in Chrome itself, like history and searches, and doesn't extend to your entire system.
Nope, they can't spy on another device that's on your network. Your activities on another machine won't be visible to your school unless you're logged into your account there.
