Yes, I remember. The most important thing in storing cryptocurrency is a creation of a special key. This process happens entirely on your device, not on Lumi wallet servers. Private keys are under client control, they are never sent or stored outside of your device.Therefore, when you generate a new wallet, you are responsible for safely backing it up. The Lumi wallet has multi-function (Holding, sending, receiving and in-wallet exchange), multi-assets and multi-token.
