问题
I understand that If a user buy something using in app purchase, it should reflect in all the devices owned by the user ( based on logged in apple id ).
But in my case I need to handle it with "our own username and not apple id". That is if user logged in to our application in multiple device, We need to handle subscription all our own.
Just to clarify, even if user logged in to two devices with same apple id but different user in our application, only the username who actually bought our subscription should get the extended access.
I believed that non-renewable subscription is what We need, but on reading a bit, I think such a subscription should reflect in all devices registered by same apple id.
So it would be great if someone could help me to select which kind of in app purchase should i choose for this scenario.
Any help appreciated. Thanks.

The kind of in app purchase for this would be preferable is non consumable. In this case user don't have to buy the product again and again. Regarding your question with your own username you can maintain the record of purchase for single user in your local server. For that what you can do is while verifying the transaction receipt from your local server which you will get on every successful transaction from apple in app purchase server. For verifying the receipt you have to send the receipt to you local server in base64 encoded format then your local server will connect to the apple server you local server will verify the receipt while sending the receipt to your local server send the session id of the user to your local server if the verification of the receipt is successful then you local server will store the purchase information in local data base. If user will login in the second device also you local server will know that this user have purchase this many item and you can sink the data in all the device in which user have logged in.
