How do y'all deal with parents checking ur phone?

My dad saw meaking a passkey for my iCloud and for some reason he got so suspicious he took my phone and asked me to open it? I said I won't cuz it's my privacy, then I got lectured so bad and it was on my most important exams in life so it ruined my mood so bad as if I'm not already dealing with pressure and stress from them. 2 days after I get my phone but my mom checks my messages cuz they're 100% I'm talking to boys, anyway she checks find nothing.. She probably doesn't believe it cuz every time I'm on my phone she asks who I'm talking to, what I'm watching and it's soo annoying and draining tho I'm still in my exams week. I finished exams 2 days ago and thought i can relax finally but today I wake up to my mom asking me to open my phone cuz she wanna check it with my dad?? I say no so she say no phone then.?? So I deleted every yaoi thing I had on my phone while shes not looking including my chrome and my massage, then my dad comes home and tells me I need to connect my mom to every account I have in all apps and they want access to all my emails..? How do I genuinely escape this shit, mind you they never ask my brother this cuz he's soooo trusty. Even if they dont find yaoi they won't like anything I talk about with my online friends.. Do y'all have tips or smth to help?
