Where NotchStar stores your Quick Note
NotchStar saves your Quick Note in its own preferences on your Mac, as plain text under one setting called quickNote. It is not a file in the Notes app, not in iCloud and not sent anywhere. NotchStar has no account to send it to.
What that means
- Saved as you type. There is no save button. The text is written as you edit it.
- Survives quitting. The note is still there after you close the notch, quit NotchStar or restart your Mac.
- Not in the Notes app. You will not find it there or in Spotlight under Notes.
- Not synced. A second Mac has its own empty note.
Where the file is
Mac apps keep their settings in a preferences file named after the app. For NotchStar the bundle identifier is com.notchstar.app, so the settings sit in ~/Library/Preferences/com.notchstar.app.plist. Treat that as a detail for the curious. You do not need to open it to use the note.
Privacy
The note is plain text and not encrypted, like any app preference. Do not store passwords in it. If you remove NotchStar and its preferences, the note goes with them. To empty it yourself, see how to clear the note.
More on limits is in Quick Note limits. The tool is described on the Quick Notes page.
