How to uninstall Notion Calendar on Mac
Notion Calendar keeps your events on the calendar accounts you connected (Google, Outlook or iCloud), so removing the app does not touch them. What stays on this Mac is the app's own local data and preferences. This guide covers the official .zip download from notion.com and the Homebrew cask notion-calendar.
Quit and remove the app
Quit Notion Calendar from its menu bar icon, then open Applications in Finder and move Notion Calendar.app to the Trash. The app was renamed from Cron to Notion Calendar in 2024, and its bundle id is still com.cron.electron, so look for that id rather than a "Cron" folder when you check the locations below.
Where Notion Calendar keeps its data
In Finder, press Shift + Command + G and open each location that exists.
| Location | What it holds | What to do |
|---|---|---|
~/Library/Application Support/Notion Calendar |
The app's local Electron data | Listed but not selected by default; keep it if you plan to reinstall, otherwise remove it after quitting |
~/Library/Preferences/com.cron.electron.plist |
App preferences | Selected by default, removed with the app |
~/Library/Saved Application State/com.cron.electron.savedState |
Saved window state | Selected by default, removed with the app |
Check the result
pgrep -il "notion calendar"
ls -d ~/Library/Application\ Support/"Notion Calendar" ~/Library/Preferences/com.cron.electron.plist
No output from pgrep means Notion Calendar is not running. For ls, "No such file or directory" means that path is already gone; a printed path means it is still on disk, which is expected for the Application Support folder if you chose to keep it.
If you installed it with Homebrew
Mole skips --zap when its list reaches unchecked or shared data, and still cleans the leftovers you selected.
The notion-calendar cask's zap list covers ~/Library/Application Support/Notion Calendar, ~/Library/Preferences/com.cron.electron.plist and ~/Library/Saved Application State/com.cron.electron.savedState. Because the Application Support folder is listed but not selected by default, Mole leaves --zap out of its own removal unless you tick that row first.
Running brew uninstall --cask --zap notion-calendar yourself moves all three paths to the Trash, whatever you had ticked in Mole. To keep the settings folder, tick nothing extra and instead run:
brew uninstall --cask notion-calendar
Account and subscription
Removing the app does not sign you out of Google, Outlook or iCloud, and it does not cancel a Notion Calendar or Notion subscription. Manage those from your Notion account settings or the relevant calendar provider.
What Mole lists
For a Notion Calendar app installed from the official download:
~/Library/Application Support/Notion Calendaris listed but not selected by default, the same as any Application Support folder named after an app's display name rather than its bundle id.~/Library/Preferences/com.cron.electron.plistand~/Library/Saved Application State/com.cron.electron.savedStateare selected by default because they are keyed to the app's bundle id.
For a Homebrew install, the zap list reaches the unselected Application Support folder, so Mole leaves --zap out and that row stays your choice.
What this test covered
Notion Calendar 1.139.0 was installed from the official zip and uninstalled on September 19, 2026, with an official Mole build (277) and Full Disk Access, as part of a ten-app batch. The app and the rows Mole selects by default went to the Trash; the Application Support folder was an unticked review row and stayed on disk.
