iCloud offers free email, contacts, calendar, and other features that are easy to set up and use. With iCloud, you can share family purchases, back up your iOS and iPadOS devices, and find your lost devices.
iCloud stores your photos and videos, documents, music, calendars, contacts, and more. It automatically keeps your content up to date on all your iOS devices, iPadOS devices, and computers where you’re signed in with the same Apple ID.
iCloud is available on Mac computers, iPhone, iPad, iPod touch, and Apple TV, and Windows computers with iCloud for Windows installed. Some iCloud features have minimum system requirements. See the Apple Support article System requirements for iCloud.
Note: iCloud may not be available in all countries or regions, and iCloud features may vary by area. See iCloud, the best place for all your photos, files, and more.
