Simplenote
Simplenote is a minimal cross-platform notes app from Automattic that keeps text notes synced across Mac, mobile devices, and the web.
What is Simplenote?
Simplenote is a note-taking application published by Automattic and available for Mac, iPhone, iPad, Android, Windows, Linux, and the web. Its main focus is lightweight text notes that sync automatically across devices, making it useful for quick capture, lists, drafts, and simple personal or shared notes. The service supports tags, fast search, Markdown, note history, offline editing, and collaboration on individual notes. Simplenote also lets users publish selected notes to the web as read-only pages, which is why some people encounter Simplenote links even if they do not use the app themselves. On macOS, the native app identified by com.automattic.SimplenoteMac is distributed through the Mac App Store, while Automattic also documents a separate Electron desktop build for some import and export functions. Users typically encounter its local files under standard Library locations for app containers, preferences, and caches.

Safety overview
Status: Mostly safe
Simplenote is a legitimate notes app from Automattic. It is generally safe to keep if you use it, but its content is cloud-synced and the service states that notes are encrypted in transit but not encrypted at rest, so it is not a good place for highly sensitive information such as passwords, financial data, or government ID numbers.
Recommendation: Keep it if you use Simplenote for cross-device notes or shared text notes. Remove it if you do not use the service. Before uninstalling, export or verify that your notes are synced to your account so you do not lose local changes.
