Apple's advertising platform uses your behavioral data to target ads, and while Apple claims to use less data than competitors, users should understand their opt-out options and the scope of data used for advertising purposes.
Apple collects a broad range of personal data including location, health and fitness information, financial data, voice recordings, and browsing and search history across its entire ecosystem of devices and services, and shares this information with Apple subsidiaries worldwide, app developers, business partners, and advertisers. While Apple publicly commits to not selling personal data, the policy permits extensive intra-group sharing and third-party disclosures that may not be fully transparent to average consumers. You can review, download, correct, or delete your personal data by visiting privacy.apple.com and signing in with your Apple ID.
