    Uninstall

    Does everything above and asks for confirmation. It runs only when nothing else is in progress.

What stays

  • Your messages and labels in Outlook stay untouched. If you want, you can delete the categories from Outlook (here is how).
  • Exports stay where you saved them.
  • The license file and the trial counter stay in ~/Library/Application Support/Klasor/ (license.json and trial-ledger.txt), so the trial doesn’t restart on a reinstall. On the last uninstall page you can tick “Also delete the license and the trial counter from this Mac”; an ended trial stays ended anyway, because the server remembers it. If you have an active license and you’re moving it to another Mac, deactivate it first on the license page.

If the app no longer starts

Drag Klasor.app from Applications to the Trash, then delete the folder ~/Library/Application Support/Klasor/ and the file ~/Library/LaunchAgents/ro.engineerio.klasor.plist by hand.
