There is a temporary cloud save option that allows you to transfer saves between devices with a code. But it's temporary and will be deleted very quickly!
Under the page for Save function there's a button called Upload Sync, you can upload your saves to the cloud, there's a code there that you need to remember then on the other device (the code expires in one hour), navigate to Load and you'll see a download save, type that code and you'll be able to download it!
