Supernote Partner
Supernote Partner is a macOS companion app for Supernote devices that syncs notes and documents, shares content, and supports keyboard sharing.
What is Supernote Partner?
Supernote Partner is a companion app for Supernote devices on macOS that helps users access, manage, and share their notes and documents from a computer. It is designed for people who use a Supernote e-ink device and want their writing, files, and to-do items available across devices. The app supports synchronization so your Supernote content can stay up to date between the device and desktop workflow. It also includes sharing features for sending notes and documents to other people, plus Supernote Linking features such as keyboard sharing for typing on a Supernote from a Mac keyboard. For Mac users who regularly move between handwriting on a Supernote and organizing material on a computer, it works as a companion utility rather than a standalone note platform.

Safety overview
Status: Mostly safe
This is a legitimate companion app for Supernote devices. It normally needs access to your synced notes, documents, and account data to do its job, and network access is expected because synchronization and sharing are core features. If you use keyboard sharing, the app also interacts with your Mac keyboard input for that feature. Keep it only if you use a Supernote device or depend on its desktop sync workflow, and sign out before removing it from a shared Mac.
Recommendation: Keep Supernote Partner if you actively use a Supernote device and want desktop access, syncing, sharing, or keyboard sharing. If you no longer use the device or prefer other transfer methods, you can remove the app and its local data without affecting macOS itself, though you may lose locally stored synced content until you sign in again elsewhere.
