Apple collects health metrics such as heart rate, fitness activity, and other sensor data from Apple Watch and iPhone if you use health features or research apps — this is some of the most sensitive personal data Apple handles.

Health data is among the most sensitive categories of personal information under GDPR Article 9 and state biometric privacy laws, and its collection creates heightened legal obligations and privacy risks for users.
(1) REGULATORY FRAMEWORK: Health data constitutes 'special category' data under GDPR Art. 9, requiring explicit consent (Art. 9(2)(a)) or another specific derogation — enforced by EU DPAs including the Irish DPC. In the US, if Apple provides services to HIPAA-covered entities, health data may constitute PHI under 45 CFR Parts 160/164; however Apple's consumer health features are generally not HIPAA-covered absent a BAA. FTC Act Section 5 and the FTC's 2023 Health Breach Notification Rule (16 CFR Part 318) apply to unauthorized disclosure of consumer health data. Illinois BIPA (740 ILCS 14) may apply if biometric identifiers are collected via sensors. (2)
