It works great. Even my parents learned what to install and not install on their windows PC. The key being that the safety features are all on by default. But for those of us that need to run software off the beaten path, we can.
I'd love to teach my parents, but I'm still challenged by giving them indicators to determine what should or shouldn't be installed. I actually find it hard to do myself, so maybe you can help. For example: My mom likes to play Sudoku. How should she go about to determine whether it's fine to install this app: https://play.google.com/store/apps/details?id=com.easybrain.... ? How can she (or I) determine whether this data is uploading data collected on her phone or doing some other sort of shenanigans?
