Apple iCloud

Apple iCloud by Apple Inc. is a cloud service that securely stores your photos, files, passwords, and more, and keeps them up to date across your iPhone, iPad, Mac, Apple Watch, Apple TV, and Windows PC. With seamless integration into Apple’s apps and operating systems, iCloud makes it simple to back up devices, sync important information, collaborate in real time, and access your content anywhere via the iCloud.com web app.

Key features:

• iCloud Drive: Store, organize, and share files and folders; collaborate on documents with iWork and other supported apps.
• Photos: Safely store your entire photo and video library with iCloud Photos; create Shared Albums and an iCloud Shared Photo Library for family and friends.
• Sync and backup: Keep Contacts, Calendars, Notes, Reminders, Safari data, and Messages in iCloud in sync; back up iPhone and iPad automatically over Wi‑Fi.
• Mail and passwords: Use iCloud Mail with your @icloud.com address; iCloud Keychain securely syncs passwords, passkeys, and payment info.
• Find My: Locate lost devices and share locations with trusted people.
• Family Sharing: Share storage and eligible subscriptions with up to five family members, with built‑in parental controls.
• iCloud+ (premium): Get more storage plus features like Private Relay (in supported regions), Hide My Email, custom email domains, and HomeKit Secure Video support.

Privacy and security:

• Data is protected with industry‑standard security; many categories—including Health data and iCloud Keychain—use end‑to‑end encryption.
• With Advanced Data Protection enabled, most iCloud data is end‑to‑end encrypted. (iCloud Mail, Contacts, and Calendar are excluded for interoperability.)

Availability and plans:

• Works on Apple devices, Windows via the iCloud for Windows app, and the web at iCloud.com.
• Includes 5 GB of free storage; iCloud+ offers larger storage plans you can share with your family.
