Does anyone here run Google classroom on their PC?

I just learned about the program and was told to download by the tutoring group I belong to in order to continue tutoring while we are all staying at home.

Apparently the program is meant as a phone app. I did some searching and found a download from a company called Blue Stack. When I tried to install the program I got a privacy violation warning. Is this something I should worry about, or should I just install the program? Before I downloaded, I found a few other sites that led me to this screen
