For users of Nebo on the Android and Windows platforms and Nebo Pro on iOS, once you have set up your MyScript account, and signed into your cloud account you can begin syncing your notes, but only Dropbox will let you see your .nebo files in the cloud. Note that these files cannot be opened or modified outside of Nebo.
With Google Drive and iCloud, your notebooks are synced across your devices, but it happens without any visible traces in the cloud. This means you can't access your .nebo files from Google Drive or iCloud. For general information about the sync feature, visit our dedicated article.
Auto-sync is enabled by default, but you can switch it off in Settings. Auto-sync doesn't back up your content, you will need to use the in-app Backup feature in Settings if you want to back up your Nebo library.
