We allow the app/website developer to add html attributes to the form to send it to the Rownd hub if they choose. In the future, we will be a bit smarter to get it all, but right now it is more manual. Of course, if you don't want Rownd Hub to store it, it does not have to.
What about the data they collect outside of your app. The point is that you cannot say anything about that, but it sounds like you do, which is false advertising.
