GoGuardian sucks and it blocks everything. It can also track your Chromebook's location whether you are at home or on vacation. Guardian makes it hard to keep passwords and private conversations to ourselves since teachers can see everything and EVERYTHING on our computers. It's like someone watching everything you do. Even though the point is to restrict people from doing certain things, there are other ways to work around that. The funny thing is, once my teacher had an assignment on our Chromebooks, but the website was restricted and the teacher didn't know the password. So GoGuardian just stinks.
