https://www.eff.org/wp/school-issued-devices-and-student-privacy is a good document detailing how education system exposes students to surveillance by technology companies and usually without a real choice to opt out. The case is for US but still relevant to a lot of institutes in India which use proprietary software.
The article also mentions a staff saying "Staff and student details—that is, full names and school email addresses—were passed to Google to create individual logins without consent from staff. I’m not sure about consent from parents."
This is relevant for our article.
