How safe is Sol Learn app?

There is an educational website called Sol Learn. When signing into the site they want to know my location and have access to my contact info. Why would a teaching site need both my contact info and my location? Also I tap on signing in through google, how safe is it to use my google password on a sight like this. I am new to apps and am not sure where to find information about apps, both the good, bad and informative.

Thanks Wiley

Slight mistake the site is named Solo Learn. I didn't realize the multi colored circle in the center of the name was part of the name.

Again thank you Wiley
