Show HN: The Creative Commons of Privacy Policies

Good point! Actually, those "various types of data" are explained within the complete privacy policy (http://www.iubenda.com/privacy-policy/www-iubenda-com/legal/...), but we are working on a more clever way to show the privacy policy summary. Do you have any other advice on it? To me it should look more compact, with icons and groups (similar to Facebook Apps' Authorization popup).

Also consider that the privacy policy is generated by adding the services (Google Analytics, KISSmetrics, Facebook Social Buttons, etc), and the rest is completely automatic. One of the features we are working on will allow more customization (e.g. adding the "scope" parameter for FB Apps)

Are you somehow involved in the project? I think that the approach is not so easy to understand for end users, but it can be considered as a starting point for further improvement. I'm in touch with Aza Raskin too, who released these beautiful privacy icons: http://www.azarask.in/blog/post/privacy-icons/

You can see a preview of the Privacy Policy that you can generate. I hope this helps you give us some sort of advice, if you'd find it useful, beautiful, crappy and so on :P
