We got ipads from school. A friend said that the teachers have access to all of my photos and google search history? However, I'm logged into Google using the same account on Ipad cell phone and laptop so I no longer have any privacy?
That can't be right at all. This would make your school extremely criminal, because your school would violate data protection
No
Your teachers have no access to a tablet, let alone your Google account.
Your teachers only see what you upload to them online (teams or zoom, depending on what you use).
Yes, sure, but if you want to avoid that you can delete the entire history
In most browsers this is called history and can be reset / deleted under settings
