When you purchase a subscription from a third-party developer within the App Store or a subscription to an individual publication within Apple News, Apple creates a Subscriber ID that is unique to you and the developer or publisher. We use the Subscriber ID to provide reports to the developer or publisher that include information about the subscription you purchased and your country or region of residence. This information is provided to developers so that they can understand the performance of their subscriptions.
If you cancel all of your subscriptions with a particular developer or publisher, and if you don’t resubscribe, the Subscriber ID will be reset after 180 days.
