@hafeez-ullah-khan for that you need to keep track of your purchases in your own server, for iOS you may validate without server by using this method validateReceiptIos But having your own Server is recommended

For Android it's not possible to check without server. you have to have server in order to validate android receipt.

Yes @codal-hkrishnani is right. Logically, you need to match with some unique userId so that the purchased items can be tracked.
