What we have found is that the average customer doesn't really understand privacy. They would likely not understand the difference between this and any website that puts the "256 bit SSL encryption" blurbs on checkout.
We are not a privacy first service per se, but do want to give users full control over their data, so let them opt out of things like a partnership we have where we analyze their driving data to match them with car insurance. Very few users take advantage of these settings.
I don't say this as a knock on the idea at all, but am sharing my experience of serving consumers outside of the tech scene. I wonder how you could package this value proposition for an ordinary user?
