It appears that Bold Apps have removed Nodal Ninja's negative review regarding selling information about clients. (I was shocked a few months ago when I found out that Shopify allows App Developers to remove negative reviews).
I have some Bold Apps, so I am contacting them directly to ask if they sell our client information. If so, I'll be uninstalling immediately. No Shopify App should be even looking at our client information - never mind selling it.
