Does my data save if I download a new file? Is there a way to transfer data?

There is a system called Renpy Upload / Download Synch - you get a code with upload synch and can download your saves on any other device.
On PC you can just download the new version ans play - Save files are stored somewhere else on the PC.
For Android, as long as you don't delete the app it's fine - just install the new one without deleting.
