Introduction to iCloud

iCloud is the service from Apple that securely stores your photos, files, notes, passwords, and other data in the cloud and keeps it up to date across all your devices, automatically. iCloud also makes it easy to share photos, files, notes, and more with friends and family. You can also back up your iPhone or iPad using iCloud.

iCloud includes a free email account and 5 GB of free storage for your data. For more storage and additional features, you can subscribe to iCloud+.

Seamlessly integrated

iCloud is built into each Apple device. To set up iCloud, you just sign in to your Apple Account on your device, then choose which apps you want to use with iCloud and which iCloud features you want to turn on or off. You can customize these settings for each device. You can also access information stored in iCloud on a Windows device using iCloud for Windows and in a web browser at iCloud.com.

Learn how to customize settings on each device and how to sign in to iCloud.com.

All your information, always up to date

When you use iCloud, you can access your photos, files, passwords, and other data on any device you choose. Because your data is stored in the cloud and not on a single device, it stays up to date everywhere.

For example, if you turn on iCloud Photos on your iPhone and Mac, you see the same photos on both devices. And if you take a new photo or delete one from the Photos app on your iPhone, those changes appear in Photos on your Mac.

Learn about the different apps and features that use iCloud and how iCloud keeps information up to date.

Safe and secure storage

Data stored in iCloud is encrypted, and with two-factor authentication, your account can only be accessed on devices you trust.

Share with friends and family

You can share information stored in iCloud and collaborate with others. You decide who can view your content and who can make changes. If collaborators make edits to the content, everyone sees them in real time.
