Hey. I like my smart watch. I enjoy tracking my biometrics and being able to leave my phone, but still be able to listen to music, calls, texting, etc.
That said, I was also the kid who rocked a calculator watch in the 90’s, and I always wanted Dick Tracy’s watch.
If you chose to share that that data, or store that in the cloud, it’s E2EE / AES-256. Apple can’t decrypt it.
If Apple didn’t do this for the Health app, they’d be running foul of a lot of new and decades old laws about biometric / health data.
Also, there is little fact that Apple literally has no marketing segmentation products that utilize medical cohorts like this. They’re trying to sell an overpriced watch, accessories, and subscription services, not targeted ads.
