Privacy policies and practical jokes
This sounds like a lot of legalese. Clearly, it was not meant to be read or understood by the mere mortal. Here is my translation of the same in easy English.
"We will not sell or rent your information. However we may sell or rent it to either an affiliate or (a very long way to say) if we get acquired. An affiliate means, (if you are not convinced or confused by the acquired bit) any person or organisation whom we directly or indirectly 'control'. Control means anyone who is our shareholder or whom we have a contract with (and, pray, how do decide to sell unless you have a contract?)."
In even simpler English, it means we can do whatever we want with your information as long we have a contract with whoever we want to sell it to.
I did not register myself on the site, of course. Learning for the day? Security consultants must learn to walk the talk!
