Help (how do I delete my account) – Twenty - Hang w/ Your Friends Review

Okay first of all, I downloaded this app a long time ago and I deleted it. My little sister got it yesterday and she was looking through it and told me it was kind of weird because it showed all her friends EXACT LOCATION. It also showed my name... mind you I deleted that app months ago but it still gives my location to this day. I was trying to figure out how to delete my account but I couldn’t find how to anywhere. Developer, how do I delete my account? The app kind of just creeps me out because it still has my location after I deleted it a long time ago. Thanks.
