An add-on is a product or feature that you make available to your customers in the context of your app: for example, currency to be used in an app or game, new maps or weapons for a game, the ability to use your app without ads, or digital content such as music or videos for apps that have the ability to offer that type of content. Every app and add-on has an associated license that indicates whether the user is entitled to use the app or add-on. If the user is entitled to use the app or add-on as a trial, the license also provides additional info about the trial.
