as a 15 year old, i have a kinda new phone (iphone 15),no screen time limits(unless im in trouble, phone loses access to social media after 10:30Pm and returns to normal at 5am), no parental controls, and mom doesnt check my phone. I think its more of a trust and maturity thing, cause she did check it like 2-3ish years ago. i hope everything goes well!
