Unsubscribe to Pandora paid app

I recently thought that I'd unsubscribe to the Pandora paid app since I can use it in Android etc. How do I do this? Does deleting the app by default unsubscribe me? (Not that I really think that is the case, I just put that forward.) I'd appreciate any help that anyone can give me to save me about $5 bucks a month. (I thought that I'd try to budget a little harder, since I really don't save enough money.)
