The right to privacy doesn't have to be in the constitution for it to exist. Read Amendment nine from the constitution below:
Amendment IX
The enumeration in the Constitution, of certain rights, shall not be construed to deny or disparage others retained by the people.
The constitution and our bill of rights is not meant to be a laundry list of what we have the right to do. The bill of rights was added to our constitution because these were the overriding concerns of people at that time. And they wanted to gurantee that the government would not deny them these rights.
The right to privacy is one of our natural, inherent rights. For example, even if the right to free speech was not listed in the bill of rights, it would still exist.
If enough busy-bodies such as yourself keep protesting though, we might have to add the right to privacy to our list of rights, since some people refuse to recognize it.
Indeed, that was the fear of some of the founders. By listing some important freedoms, they feared that eventually those listed would become assumed to be exhaustive. Although their fears have been born out, one can also say that had they not be listed at all, even those rights would now be long gone.
