Just a heads up regarding the latest version of the app. It doesn’t provide cross device syncing yet, but it allows you to sign in to your Google Drive account and have all your data automatically backed up to make sure they are safe at all time. It also makes restoring the data on a new device really easy.
You can go into Settings/Backup to enable this and sign-in

I think you can now synchronize with Google drive without having to pay anymore. It's like a hidden storage like what's app is using or so.
