It blocks sites that I genuinely need for school and is an invasion of privacy. Please just let me use my grammarly in peace.

This may or may not be a helpful review, but I currently attend a school that is using this extension/software and while the extension is innocent in itself when used INSIDE the school, outside the school could potentially be a different issue when the school decides to leave the proxy/filter/screensharing online outside of school hours. Sure, the features are fine when used properly with proper disabling of them after school hours, but there are risks that a teacher could potentially watch your screen outside of school which is not only the parents job but could also be categorized as a 4th amendment violation depending on when they are watching your screen. Overall, good idea but really, really bad execution.
