iCloud

iCloud is Apple's cloud storage and computing service, integrated across iPhone, iPad, Mac, Apple Watch, and Windows PCs. It automatically backs up photos, videos, documents, contacts, calendars, and app data, syncing them across all of a user's Apple devices. The service is aimed at individual consumers and families who own Apple hardware and want their content accessible and up to date on every device. Core features include iCloud Photos, iCloud Drive for file storage and sharing, Find My for locating lost devices, and Keychain for securely storing passwords and payment information. Storage plans range from a free tier to paid subscriptions that increase capacity and can be shared among family members through Family Sharing.
