Is one of your parents less stricter then the other and do you think you then talk to that parent about this ? Because 14 (in my opinion) is waaaaay too old for them to be doing this.
(Like with my mum and dad, if I don't agree with something , I know my mum is a lot more likely to listen and be more understanding, where as my dad Is more irrational. )
Picking a good moment to bring this up with them when they're more relaxed, not stressed, busy or in the middle of something.
For more freedom learn to compromise with them about going out with your mates or whatever else you want to do. E.g. if they ask you to do house work, say you will (and do it) but ask If you can go out with friends or whatever? They will also need to know they can trust you so it's always good to send a text when you are out.
