If your build is not using encryption, use the key string value in your Info.plist file so you don't have to provide export compliance information with your next build.
Is your app designed to use cryptography or does it contain or incorporate cryptography? (Select Yes even if your app is only utilizing the encryption available in iOS or macOS.)
