It is likely simmilar to paid apps that have market checks built in. Currently Rio is only available on the Amazon market, it is a check to keep people from getting the app from warez sites and to drive people to use the Amazon market. I doubt it is sending data to amazon I was able to start it up just fine while my phone is in airplane mode.
