The data download that users are able to request includes purchase and app usage history, calendars, reminders, photos, and documents stored in iCloud, Apple Music and Game Center statistics, marketing history, and AppleCare support history.
The data download option arrives before the GDPR deadline and is currently limited to Apple accounts registered in the European Union, Iceland, Liechtenstein, Norway, and Switzerland, but Apple says it will roll out the service worldwide "in the coming months".
We've compiled a separate how-to outlining the steps involved in requesting the data. If you live in a country or region that's not listed above, you can still contact Apple to request a copy of your data.
The new Data & Privacy site also includes links that customers can use to update their account details, temporarily deactivate their account, or delete it permanently.
