I don't get it either. How is this different than a "left luggage" place? A coupla' years ago, I landed at Heathrow, dropped off my luggage at the left luggage shop, travelled through Europe for two weeks, went back to Heathrow, picked up my luggage and flew back home. Just google "left luggage near me" when you land somewhere. No need for an app that is most likely (not necessarily nefariously) tracking you.
