I’m 20 and my parents are still tracking me

So my parents made me and my siblings get this app called Life360 when I was 18. I’m a good kid. I get good grades and I tell them where I’m going and who with at all times. At first, I didn’t care because I was still in high school and I had no social life. Now I’m in my second year of college. I still get good grades, tell them what’s going on, and call them almost everyday. I’ve done nothing to lose their trust. I also joined a few clubs and got a boyfriend towards the end of last school year! My parents are now questioning every little thing I do. I feel like they don’t trust me anymore! I got a new phone and my location was off for the app because it didn’t ask me to set the location yet and I didn’t know it was off. My dad then texted me “turn your Life360 app back on.” And I said “It switched to only when I use the app. I don’t know if it did it when I got the new phone.” He said “It just turned back on. Why are you a liar? What are you hiding from us?” Then I sent him a pic of me doing laundry and said “you caught me!” That was when I started to realize what control the app had on the trust my parents had for me. Then I was in my developmental psychology class and the topics were types of parenting styles. My professor asked what types of parents we think we have. I said authoritarian and she asked why. I told her about the app and her eyes went wide open and her jaw dropped! Like it actually dropped because of that! She tried to respond nice and polite and say “oh that’s a little odd.” And she moved away from the subject. That’s when I realized this was not normal at all! Then two nights ago, I was going to my friend’s house to sleepover there because I didn’t have class the next day and neither did she, so we thought why not?! I texted my parents I was going there and they FREAKED! Now I go to a lot of parties late at night and I go to club lacrosse tournaments out of town and they’ve never questioned me. I always tell them what I’m doing. It was 9:30 at night and my parents said “I don’t like this! It’s too late! Are you sure that’s where you’re going?! Are you lying?! Do you really not have class tomorrow?!” I felt like all trust was just lost that night. I’m going to tell them I want to be taken off the app, but I’m afraid they’re going to turn off my cell service or they’re gonna pull me out of school or something. I need help finding a way to say this because I can’t live with this app anymore. It’s ruining my relationship with them. What should I do?!
