Ensure that my game doesn't use internet

I am making a game for Android and iOS. How do I make sure that my game does NOT use the internet?

With Android, it seems as though I have to specifically ask for permission in the manifest. Before, publishing, I will check the manifest to ensure that is does NOT request internet access. What about iOS?

 

Hello,
I'm not sure it's possible for a game to connect to internet if you do nothing for the game to connect. Internet access isn't an easy thing to do, it won't happen by accident.
There are ways to check if the device (computer, phone...) is connected to internet, but having an internet connection doesn't mean your game is connecting somewhere.
