Im creating a small Game for Android and iOS where users can buy contingent per inApp purchase.
What is the best way to save this contingent, to persist after reinstallation without a own server?
Since there is no similar feature in Android as there is in IOS for the keychain, there will probably be no secure option without having your own server.
