How to Uninstall the Trello Desktop App
Removing the Trello Desktop app is as easy as using the default "Remove Programs" tool on windows, or deleting the app from your "Applications" folder on a Mac. To fully remove the app and app data from your system, use the steps below.
1. Go to your system's container directory ( Finder -> Go -> Go to Folder ... > "~/Library/Containers/").
2. Remove your com.atlassian.trello directory by dragging it to the trash.
Go to your system's application support directory (Enter %APPDATA% in the address bar of your Windows Explorer). 2. Delete your “com.atlassian.trello” directory.
3. Delete the “Trello” directory.
