I contacted some app developers, but I got no response. I have played 21 Questions, Truth Game, and Chess help?

I have played Chess, 21 Questions, and Truth Game app on Facebook. I haven't played them for a very time like two yeas. I removed some apps from my Facebook app settings. Later, I learned that app developers may have some data since I clicked "allow". A few weeks ago, I emailed to them to request for deleting all my information, but I got no response. I am not sure why. Maybe my email address is already changed on my Facebook, but I have still my old email address.

Any idea?

You can delete the app, but I don't think you'll be able to get them to delete your data

I dont think data will harm you by any means, you can now ask facebook to help you in this regard. They will assist you in removing the app from your profile or you can disallow it yourself by going to the settings section.
