Keeping data meta, I think, is a good way to go. No identity attached, no personal photos. Just all info going from A to B. So it's folk-able. I really like the toggle(switch) buttons, I hope it's not linking to external service (oh it is).
I had put thoughts so much on this kind of apps and it's abandon because I wasn't able to think of how it's monetized.

Can I ask where's your data/pricing from, if your source is not secret?
