Looking for no-frills loyalty (rewards) card app

[geodosch]

I'm trying to find an app that will store my barcoded shopping cards. Something like Key Ring (which I currently use), but without all the bells and whistles. I don't need the app to track my every move, and alert me when I'm near a store where there are specials, or send me circulars from my stores, or help me with my shopping lists. It seems that every one I've found has recently added these features. I just want to get rid of the dang key tags! Is that too little to ask? :-\
