COVID Alert NJ is New Jersey's free and secure mobile app that anonymously alerts users if they have been in close contact with someone who has tested positive for COVID-19. The app also provides users with up-to-date information on New Jersey reopening news, key COVID-19 metrics, and a user-friendly symptom tracking tool. COVID Alert NJ uses Bluetooth proximity technology. The app will never record any identifying data. All users will remain anonymous. When your app senses a close contact, your phone will exchange a secure random code with the close contact's phone. Each day, the app will compare your list of close contact codes to the list of codes associated with positive COVID-19 app users. If there's a match you will get an Exposure Alert, along with appropriate next steps. It's important to note that your location and name are never disclosed
