First of all we can ensure that the only info we have from you is your name, email (if you granted us permission) and game progression and we have not and will never share any of your data with third parties.
If you still want us to delete your data, it's easy. The only thing we need is your Facebook user ID for our game (this id is only valid for this specific game, so you can trust we won't use for anything else). You can easily find it by following this steps: https://www.facebook.com/help/1397933243846983.
Once you have got your user ID, send an email to firstname.lastname@example.org with the subject Aliens in Chains Data Deletion Request and include that ID in the body of the message. We'll reach you shortly after to confirm your request.
Thank you for trying our game.
