We strongly suggest using the Waterspeed Cloud, login and let the app manage your data automatically. It will also give you the automatic sync with the iPad.

However, Waterspeed is able to backup your activities on your iCloud Files space, in order to recover in case you want to change the device or re-install the app and you are not connected to the Waterspeed cloud. 

Waterspeed will perform a backup automatically every day (or as soon as you open the app) on your iCloud and on "on your iPhone" Files space. So you will be able to reuse those files in the future.

You can also do a manual backup in order to get an updated one, using the tool in the Settings tab. It will save a proprietary file into your iCloud space locally and overwrite any older backup. 

Please note: Backup uses your space on the iCloud drive.

Restore: please contact the Waterspeed Support.
