Hi @ChenchenXu. You can use the SDK pretty much anywhere. But your question is not one that can be answered here. You need to check with Apple (or any other App Store) to determine what their policy is. I don’t know why they wouldn’t allow it, but each one has its own terms of service that you are required to understand.
