The UUID is used to create passphrases for the blockchain wallet with a local currency that is automatically selected based on the device's location, region, and language. For maximum security, the passphrases are stored in a secure enclave and backed up to the user's private cloud, provided by Apple and Google. Asdra does not store any data on its server. The user can access the information associated with the passphrases, create additional backups, and remove online backups at any time.
