Money help

Briana

So I am 15, I have a job and a bank account owned by solely me and I just have a few questions about money and parents:

1. If I buy something with my money can my parents still take it away? (Shoes, AirPods, posters)

2. Can my parents still take money from me like it’s theirs?

3. If I’ve gone out shopping and bought stuff that I like can they make me return it or like take away my “money privileges”?

4. If I pay a professional to pierce my ears/dye my hair can they make me undo it?

Sorry I’m just not sure where to post this
