Precise location data, for example GPS signals, device sensors, Wi-Fi access points, and cell tower locations may be collected when you use certain Apple services or features such as Find My, Maps, and location-based features of the App Store.
Precise location data can reveal highly sensitive information about a person's daily routine, home, workplace, medical visits, religious practices, and associations, making it one of the most privacy-sensitive data types collected.
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.
