People with strict parents please help me

Okay so my parents are kind of strict And thay put a lot of restrictions on my phone to the point I can't even do anything without them having to put password in and everything has to be 9+ only Like girl My little cousin can get games older than that And thay also made it so I can't get private browsing mode or delete anything And to be honest this just isn't fair like im old enough to not have the restrictions and to my phone to be off by 12 Like I could understand if I was 10 or something but I'm not And I already tried the thing Where I put screen recording on and try to see the password But I'm guessing Apple seen The Trick already And I have the apple 15 so they made it so you can't see the password as it's being put in on screen recording And honesty all I want to do is talk to my friends And play games that are not meant for nine year Olds So I went into settings and I found out this thing Where you can make a different account for yourself on it like a separate account for you on Safari Andy looks like anything I search on there doesn't go on to the my main account on there But I Want to Know can my parents see what I'm searching on their still Like my dad made it so our phones are connected and I'm In the Family thing or whatever so can they still see everything I search on that account Like does it go to him or no? Also any tips on how to find out the password or Get rid of the time limit thing so my phone doesn't go off by 12? Like please help I'm literally using a TV to type this right now
