How do I restore my data if my iOS device is lost, replaced, or during re-login?

Ensure you've backed up your data in the OtoZen app (Short Cuts -> Backup Trips).

To restore your data:

Log in to your OtoZen account with the same number.
Make sure the device has the same iCloud account used for the backup.
If a backup is found, OtoZen will automatically restore all your drives.
If no backup is found, data cannot be restored as OtoZen does not store personal data on its servers.
