Whatever you open here stays on the device by itself. One press and the site fetches this whole language pair, with all its exercises — once, and after that you can practise on the train, in the waiting room and on the plane without a connection. It tells you first how much that is and checks whether there is room. Your progress was only ever stored here anyway.
