Apple iWork is Apple's office suite, made up of Pages (word processing and page layout), Numbers (spreadsheets) and Keynote (presentations). The apps run natively on Mac, iPad and iPhone, and web versions are available through iCloud in a browser. All three support real-time collaboration, and Pages and Numbers also let people join from a PC. On macOS and iOS iWork has been free since 2017; extra content and AI features come with the Apple Creator Studio subscription. Documents are stored in iCloud Drive.
Apple is a publicly listed company headquartered in Cupertino, California, and iWork is proprietary software. Apple states that both Apple and third-party data centres may be used for iCloud; its documentation describes no choice of region. By default, iCloud data is encrypted in transit and at rest, with keys held by Apple. With the optional Advanced Data Protection, iWork documents are end-to-end encrypted, but shared iWork collaboration is not covered. As a US company, Apple is relevant for the CLOUD Act.
