I believe Google's patent/trademark search engine is most popular.

But I don't mean just Google. Also any other popular patent/trademark search engines.

My Q:

Can someone point me to privacy policy(s) which guarantee the public that not one other person other than the person searching for "keywords" (which may be a DEAD GIVEAWAY of his/her idea) has access to search terms,

...on any/all of the most popular patent/trademark search engines?

Or if this topic has already been discussed on these forums, I'd appreciate the link, and apologize for the topic rehash.
