Curfew for 14 year old

What would you guys say is an appropriate summer curfew for a 14 year old girl? Living in the city btw if that makes a difference. I'm preparing to convince my parents to enstate a curfew for me and I would like to know what you think is reasonable, or if it is reasonable at all... Thanks for your help!

(Edit: the reason that I want a curfew is just so i know when i need to be home as opposed to having to check in with my parents every 30 minutes letting them know where i am and when ill be home )
