What is iCloud?
iCloud securely stores your photos, videos, documents, music, apps, and more—and keeps them updated across all your devices. With iCloud, you can easily share photos, calendars, locations, and more with friends and family. You can even use iCloud to help you find your device if you lose it.
To get started, just set up iCloud on your Mac, and on your iOS devices, Apple Watch, Apple TV, and Windows computer, too.
To set up iCloud on your iOS device, Apple TV, or Windows computer, see the Apple Support article Set up iCloud on all your devices.
Here are some ways you can use iCloud.
