A simple digital Taplist solution

This is pretty neat and priced just right for my cheapness. The only thing I'd love to see is getting the data to stick. I was looking to run it on my Raspberry Pi that runs CraftBeerPi which I use to manage my fermentation Freezer and my kegerator. Thought I'd put a display on it as it sits on my kegerator. However, I then thought why not put it on my Synology NAS as a website... alas the persistent data gets me.
So any thoughts on persisting data between the Pi, phone, and my computer would be fantastic. I can reverse proxy the NAS to my wordpress/website, that would be helpful.
