If you lose your phone or tablet, don’t worry, your submitted data is saved in the cloud and backed up so you will not lose any of that information. If you have started forms on the device as long as they have been saved (this happens automatically every 15 seconds) they will appear on the Web Portal > Forms > Saved Forms.
When the device is replaced, simply login and your account will be setup with all saved data restored.
If the device has been set to remember the password, then you will need to access your Web Portal and change your password to ensure the account's security.
