There is no "right to privacy" in the Constitution.
Yes there is.
Where?
In most of the first ten amendments, Alcon, and in all of them taken together.
Here. I will make this easy. Here are the first ten amendments of the U.S. Constitution:
1. Freedom of religion and expression
2. Right to bear arms
3. Quartering soldiers
4. Search and seisure
5. Rights of persons
6. Rights of accused in criminal prosecutions
7. Civil trials
8. Further guarantees in criminal cases
9. Unenmumerated rights
10. Reserved powers
Where, pray tell, does the right to privacy find itself here? If it is as simple as you seem to imply, I'm sure you'll have no trouble in compiling this information.
