Apple has released a new data & privacy portal that can be used to download data that is linked to your Apple ID. This data can include transaction history, app history, AppleCare history, marketing data, and more. To access the portal, you need to go to https://privacy.apple.com and login with the Apple ID associated with your account. Each data category will be compiled into its own archive that you can download. For textual data, it will be delivered as a spreadsheet or in PDF, CSV, or PDF files.
