Q: Personal information for watch

Hi

Health and activity data is shared to the Health app on your iPhone and can also be viewed in the Activity app on your iPhone.

It is not shared with any other apps without your permission.

It is not included within iPhone backups unless they are encrypted (iCloud backups are encrypted as standard).

Further information about Apple's privacy management features - including for Location Services data - is available via the links below.

Measures include your iPhone asking for your permission before giving any app access to your GPS / location information, including apps on your paired Apple Watch:
