One of my priorities is end user privacy so I'm trying to minimize how much access my service would have to the users library of photos.

Rather than me scan all of the photos I'd prefer the user manually select them. Plus, you get the bonus feature of also getting to review your own photos again :) I find a lot of the time I never go back and look at photos I take. I'm trying to evoke feelings of printing photos and putting them in an album. Digital is no substitute for physical, but if I can get close I'll take it haha

I am considering some ease of use features like library scanning / tagging maybe on an opt-in basis perhaps.
