Summary
I show how to completely uninstall a JourneyApps application on Windows and delete all residual data. First I uninstall the app through Settings → Apps using the normal Add/Remove Programs method. Then I open Explorer, enter %localappdata% and delete the folder named after the app, followed by %appdata%\Roaming where I remove the same folder. After these steps the app and all its data are gone, allowing a clean reinstall if needed.
