tracing apps

Tracing apps are digital tools designed to help identify and notify individuals who have been near someone infected with a contagious disease, like COVID-19. They use Bluetooth technology to anonymously detect and record close contacts with other users' devices. If a person tests positive, the app can notify those who have been in close proximity, enabling timely guidance and self-isolation to prevent further spread. These apps prioritize privacy by not sharing personal data and function as a supplementary measure alongside health guidelines.
