Glad that you like the app

I'm not sure to get exactly what you mean by "export this data". If you mean export the wav files, then you were on the good direction with copying the weblink to your PC's browser.
The page showed should display a list of all your loops with some details (length in seconds, last modification date), and for each loop there is 4 colored little rectangle on top of each other which correspond to your 4 tracks.

If that's not what you would like to do, I think I need more explanation on what kind of data you want to export.
