How to uninstall Notesnook on Mac
In Notesnook, open Settings › Backup & export and create a .nnbackupz backup before removing local data. Keep the backup and its account password safe, and store your account recovery key separately. If you need notes in another app, the same help center documents export to Markdown, HTML or text; open a sample exported file before deleting anything.
The recorded test used the official Mac package; the Homebrew route below is separate.
Remove the app
Quit Notesnook and move Notesnook.app from Applications to Trash. Do not discard the only encrypted backup or local note state merely because another device displays an account name. Check that the backup can be located and the wanted notes are available before selecting the support folder.
Review local data
The path below is documented in the current Homebrew cask. In Finder, use Go › Go to Folder to inspect it. Do not remove its parent directory or another product’s data.
| Location | Decision |
|---|---|
~/Library/Application Support/Notesnook |
Cask zap location and the first-run folder removed in the recorded test. It may hold local note state; retain it until backup is verified. |
The tested package uses bundle ID org.streetwriters.notesnook. Review only files that actually appear on this Mac. A missing path needs no cleanup.

Check what remains
Run these read-only commands after quitting the app:
pgrep -il 'Notesnook'
ls -d "$HOME/Library/Application Support/Notesnook"
No process output means there is no matching process running now; it does not prove every helper is gone. A listed process needs its owner checked. If ls prints the path, that item remains and needs review. “No such file or directory” means this path is absent; a permission error means its state was not established.
If you installed it with Homebrew
The current notesnook cask has a zap list covering Notesnook support data, logs and preferences. A direct brew command with --zap applies the cask list without consulting Mole’s checkboxes. After backing up, use this command without --zap:
brew uninstall --cask notesnook
Mole checks each zap path against your selections, other installed apps, and protected locations. An unchecked, shared, or unverifiable path suppresses --zap; selected remnants can still use Mole’s own removal flow. This cask was not the recorded installation channel.
What Mole lists
Mole lists Application Support/Notesnook as an app-name review row, initially unchecked. Exact bundle-ID preferences can be selected by default. It cannot verify the contents or decryptability of your .nnbackupz file, so leave the support row unchecked until your backup is ready.
What this test covered
The official Notesnook.app 3.4.8 was removed on September 21, 2026, and a 2.3 MB Application Support/Notesnook folder was selected. No note collection was created, so the test did not verify backup, sync, recovery keys or deletion of populated note data.
