France's Virus Tracing App Ready to Go, Parliament to Vote Associated Press PARIS - French lawmakers were set to vote Wednesday on whether to endorse a contact-tracing app designed to contain the spread of the coronavirus amid sharp debate over privacy concerns. If approved, France's StopCovid app will be made available to users on a voluntary basis starting Monday. The government committed to honoring the result of the non-binding parliamentary vote. French privacy watchdog CNIL backed the app this week, stating the technology "won't lead to creating a list of infected people but only a list of contacts using pseudonymous data. It does respect the concept of data protection." The app uses Bluetooth signals on mobile phones to trace individuals that people infected with the virus had contact with and informs them of potential exposure so they can self-isolate. It will store anonymous data in a government-run centralized database for 14 days before erasing it. How Contact Tracing Apps work .
