Apple HealthApple is very keen to emphasize how highly it prioritizes your privacy. Data in the Health app is encrypted both on your devices and on Apple's servers, and if you have two-factor authentication turned on for your account (which you should), not even Apple can look at the health logs you've built up.You can read Apple's privacy policy here but you should also read the privacy policies of the various services you link up with Apple Health. To see which apps are currently connected to Apple Health, open the app on your device, tap your avatar in the top right corner, then choose Apps under Privacy.Note that the permissions on the next screen will be split up into write permissions—the app can add data to Apple Health—and read permissions, which means the the app can take and use data from Apple Health. You have the option to disable any permissions, to disconnect the app completely, and to fully delete all the data the app has collected—at least in terms of what has been shared with Apple Health.READ ALSO:
