Apple Watch Sleep Tracking in watchOS 27: Every Confirmed Change for Series 12 and Ultra 4
Apple Watch Series 12 and Apple Watch Ultra 4 both list a sleep score and sleep apnea notifications, and both add an overnight vitals view that compares Recovery HRV with your personal baseline.

Apple Watch Recovery HRV vs Overall HRV: What Apple Says Separates the Two
Apple Watch Series 12 and Apple Watch Ultra 4 measure heart rate variability every five minutes, and Apple reports the result in two named forms: Recovery HRV, which it ties to daily stress and recovery, and overall HRV.

Apple says its new movement evaluations use the iPhone camera to assess flexibility, strength, balance, movement mechanics and VO2 max, and that the whole process runs entirely on device with no video recorded, stored or shared.

Apple Intelligence Data Handling: Eight Questions Apple's Own Pages Do Not Answer
Apple has published more about Apple Intelligence data handling in footnotes than in documentation.

Private Cloud Compute: The Two Promises Apple Publishes About Your Data, and the Ones It Does Not
Apple publishes two sentences of substance about Private Cloud Compute, and both describe what does not happen to your data.

Where Apple Intelligence Runs in iOS 27: On Device, in Private Cloud Compute, and Nowhere Else Apple Names
