How many times is the word privacy mentioned in the Constitution (considering articles and amendments)?

The word "privacy" is not explicitly mentioned in the United States Constitution, including both the Articles and the Amendments. However, the concept of privacy has been interpreted through various amendments, particularly the First, Third, Fourth, and Ninth Amendments. Legal scholars often cite these amendments in discussions about rights to privacy, such as the protection against unreasonable searches and seizures and the implied right to privacy in personal matters.

While the term itself does not appear, court decisions, particularly in the context of the substantive due process and the right to privacy, have played a significant role in shaping the understanding of privacy as it relates to constitutional law.
