We hired an external team from Eastern country. They built our mobile game app using Unity3d which we paid a lot of $K. We asked them to only use the software with bought license, not cracked one, and they said they will do it.
Now, we're ready to publish apps to official stores and I read on the net that guys from unity3d can always check if the app was made via bought license or via cracked software. If they discover it's been made with cracked software, they will ban the app and probably prosecute us.
Where can we find such tool to confirm that our software was indeed made by 100% licensed unity3d piece of software?
