Can my school legally keep my phone over night?

Yes, schools can legally keep your phone overnight if it violates school policies. Many schools have rules against using phones during class or specific school hours, and they may confiscate devices to enforce these policies. However, the school typically must follow a process, such as notifying you or your guardians, and should return the phone after a set period or at the end of the school day. It's important to check your school's specific policies regarding phone usage and confiscation.
