Apple Notes is the note-taking app included with Apple devices, showing the same notes on Mac, iPhone and iPad through iCloud. Users create notes with formatting, lists and tables, add photos, videos, PDFs and other attachments, draw with the Markup palette, record audio with a searchable transcript and have calculations solved inline. Notes can be organised with folders, smart folders, tags and pinning, locked with a password and shared with others. The app is part of the Apple ecosystem and is not used separately from the devices or iCloud.
Apple is a US company headquartered in Cupertino, California. By default, notes in iCloud are encrypted in transit and on the server, with Apple holding the keys. With the optional Advanced Data Protection feature, notes are end-to-end encrypted and only your trusted devices hold the keys; some metadata, such as creation and modification dates, remains under standard protection. The software is not open source and cannot be self-hosted.
