It's not supposed to. It's more like being able to search your computer as if you were searching through an FTP server, accept that only you can access it... And anyway if it were to give information out, there isn't much that it could, and depending on the scripting, would probably be blocked by your firewall, if you have one...

But most of this is generalizations, I haven't actually tried the service or anything, at least I haven't tried it yet.
