Deleting a sketchy app

So recently I downloaded an app. Didn’t thought much about it. Started using it, it asked permission for camera microphone and photos. Since the app is all about stuff like that I allowed access. But then I read some articles and reviews that said: it’s listening to you... it’s tracking you.. etc. Creeped out by the situation I deleted the app. But my question is did I really delete all my data from that sketchy app? After all, it isn’t connected to my iCloud Facebook game center or any thing. If you are wondering what app I downloaded then it’s this app called zepeto. Seemed cool at first. Got creeped out later on.
