Everytime you modify your profile, you are prompted on the homepage of the mobile application to backup your identity.
When you click the "Backup" button, all the personal data stored on your mobile phone is compiled and encrypted in a binary file. Only your password can decrypt this file.
Once the file is created it is sent to the email address provided in your profile. (version 1.0)
From v1.2, additional options are available for storage of your backup file (the Myki app, iCloud, Google drive, Dropbox, etc.) You decide where to store it!
