How to Review your Apple Watch’s security

Check your privacy

Since your Watch will share the health settings, location services, contacts, and analytics collected by your iPhone, first make sure you lock all these down. Open Settings on your iPhone and tap Privacy.

Turn off Fitness data

Privacy settings can be adjusted to stop your Watch sharing your motion and fitness data. To do this, open the Watch app on your iPhone, then tap My Watch > Privacy and select “Motion & Fitness.”

Check Activation Lock

Protect your Watch against theft by ensuring the Activation Lock is on. Tap “My Watch,” select your watch name at the top of the screen and tap “i.” If you can see “Find My Apple Watch,” the Lock is activated.

Alter the settings

You can turn Location Services off and see which apps request access to your contacts and health data. Under Analytics, you can turn off “Share iPhone & Watch Analytics.” There’s also a “Share iCloud Analytics” option.

Move the sliders

Within “Motion & Fitness” you’ll see two options — one that allows the Watch to monitor your heart rate and another that determines your step and fitness levels. You can turn both of these off.

Disable the Watch

If those words don’t appear, see our sidebar for how to set up Find My iPhone. Log in when prompted, and you can locate your Watch on a map, play a sound to help you find it, remotely erase it, or enter Lost Mode.
