The RVN Wallet connects directly to the cryptocurrency networks, where your wallets are stored. The "keys" to access your wallets are securely stored in your phone and nowhere else. The RVN Wallet will provide you with a unique "Recovery Phrase" which is a list of 12-words which can be used to recreate the keys to your wallet. If you ever lose or upgrade your phone, this 12-word Recovery Phrase is required to regain access to your funds. Please write down each word, in order, on a piece of paper. We recommend storing your 12-word Recovery Phrase in a safe, safety deposit box at a bank, or wherever you might keep passports, birth certificates, or other important documents. Anyone who has your 12-word recovery phrase can access your money, even if they don't have your wallet PIN, so keep it private and don't show it to others!
