The Department uses social media websites and other kinds of third-party websites. The Department uses social media websites to interact with foreign constituencies and engage in public diplomacy worldwide. Social media websites are used to publicize embassy and Department events, and engage with members of the public in foreign countries. The Department also uses web measurement and customization technologies to measure the number of visitors to our websites and their various sections and to help make our websites more useful to visitors. In such cases, the third-party application may request an email address, username, password, and geographic location for account registration purposes. The Department of State does not use third-party websites to solicit and collect PII from individuals. Any PII passively collected by the third-party website will not be transmitted or stored by the Department; no PII will be disclosed, sold or transferred to any other entity outside the Department, u
