Yes, you will lose the data if you delete/uninstall the app without synching to a browser DMM account or to another mobile device.

If you're having black screen on your 2nd mobile device, try making sure you have sufficient space for the data to download and make sure your internet is stable or fast enough. Try and wait at least 5 to 15mins (depending on your internet connection) to see if there's any sakura spinning during black screen.
