When you're away from the prying eyes of others, you have privacy — you're alone, secluded, and not in the public eye.
Sometimes you just don't want to be bothered by anyone, so you seek a place where you can be alone with your thoughts, free from distractions or intrusions. When that's the case, you are seeking privacy: private space and time away from others. Privacy has always been an issue for celebrities, who are followed around by photographers. If you value your privacy, don't run for office: politicians give up their privacy when they run for election.
