That's called "EdTech".. It's a huge industry of cloud providers all with very dubious privacy, which you cannot opt-out of. Much like you cannot opt-out of whatever slurpy tech your employer uses.
I found DJI's "RoboMaster" competition a little bit horrifying when seen through my cynical lens.. A bunch of kids write software on DJI's cloud platform to control toy robot tanks to battle eachother. I'm sure DJI would never ever do anything evil with that data.. right
Get the kids to teach the machine how to shoot, then tell the machine to shoot the kids.
