I'm going to keep my parents from tracking my phone
Why do you want to stop your parents from tracking your phone?
Because I want a life of my own.
It isn't ethical for them to spy on you and it can lead to a lack of trust in your relationship, possibly even doing irreparable damage in the long term. Talk to them about this and make sure you maintain your position of wanting to be your own person.
I'm going to spy back on my parents and check each of their bank accounts.
It will make the situation even worse. If you care for your privacy so much you should give your parents the same level of privacy. You better talk to your parents and ask them politely not to track your phone.
