We mentioned everything in document file how to add database in this app and we must verify purchase code to share database files to our buyers to avoid null and scams second thing is that you already got everything on your email even our other buyers using our apps without any problem and they published our apps on Play storealso giving us good review so we didn't know why you are lying here and trying to disturb our rating. Well God Bless you. :-)
