Starting on Wednesday, Apple will allow US users to download all of their data from the company, following a GDPR-mandated feature for EU citizens that launched in May. The download tool is accessible from the company’s Data and Privacy page, and it encompasses device-syncing data like iCloud bookmarks as well as iTunes purchases and retail-level information like your Apple Care support history. Users will have to authenticate with their Apple ID before receiving the data.

The new availability comes as part of the launch of a revamped privacy page, which emphasizes Apple’s data-retention policies and differential privacy efforts. The new page encourages users to turn on two-factor authentication and gives them the option to opt out of targeted ads and notifications from Apple. The company’s use of differential privacy has expanded to many of the new features introduced with iOS 12, including Memoji characteristics like hair length and Screen Time’s classification of specific websites.
