Microsoft OneNote
Microsoft OneNote is a digital notebook app for capturing, organizing, and syncing notes, lists, drawings, and reference material across devices.
What is Microsoft OneNote?
Microsoft OneNote is a note-taking and information organization app that helps you keep notebooks, sections, and pages for work, school, and personal projects. It is designed for users who want a flexible place to collect typed notes, handwritten annotations, images, checklists, and research in one workspace. On Mac, OneNote is commonly used for class notes, meeting notes, project planning, and saving material that needs to stay searchable and easy to revisit. It also supports sharing notebooks with other people, which makes it useful for collaborative planning and group study. Notes can sync across supported devices and the web, so you can continue working from different locations. OneNote fits best for users who want a general-purpose digital notebook rather than a traditional word processor or document editor.

Safety overview
Status: Mostly safe
Microsoft OneNote is a mainstream note-taking app from Microsoft. Its network access, cloud sync, sign-in, and optional microphone or file access are consistent with a notes app that stores and syncs notebooks across devices. Because notes may contain personal, school, or work information, review your Microsoft account sign-in status and sharing settings if you use collaborative notebooks or store sensitive material.
Recommendation: Keep Microsoft OneNote if you use it for notes, research, classwork, meeting records, or synced notebooks across devices. If you no longer use OneNote, you can remove it like other apps, but doing so may leave your cloud notebooks in your Microsoft account and may remove locally stored offline data from this Mac.
