APDL is "data everywhere" meaning it is synced across all of your devices that you are signed in with your NC Software account.  We use a custom built, high speed secure reliable enterprise data sync system we engineered at NC Software.  We do not use Apple's iCloud system which has been troublesome, unreliable, and broken such as in the iOS 8 upgrade.  With the NC Software sync system you will find your data quickly synced to the cloud and across devices.  In addition APDL's advanced sync system is also a data backup.  APDL data is backed up multiple times daily and we can restore a user's data on request.
