Another thing. Don't you have a bad feeling uploading images of your kids, conveniently tagged with their age, to a random web service that promises to delete the images without even revealing the makers?
I mean yes, it looks legitimate and you can find a person on Twitter who seems to be the maker of it, but that's not a guarantee for the safety of the uploaded images. I'm not a data paranoid, but careless sharing my kids' images with a random service like that crosses a border.
