My school installed something called 'Securus XT' onto my laptop. I knew it was meant to be a safeguarding thing but I didn't know they would be able to see every single thing I do on my own laptop (the school didn't give it to me). They saw things I was doing at home not even on the school Wifi and it just does not seem legal. I'm 16 and live in England.
It is not illegal for anyone to install anything on your laptop - or other platform - with your consent.
You might get round that if you were too young to give legal consent… were you?
It might also be that you were not shown some part of what information should have been required for you to give "informed consent"… were you?
If you were neither too young nor not fully informed what will you rely on in court?
