PARIS—France is rolling out an official COVID-19 contact-tracing app aimed at containing fresh outbreaks as lockdown restrictions gradually ease, becoming the first major European country to deploy smartphone technology amid simmering debates over data privacy.
The StopCovid app launched on June 2 just as the French government started allowing people to once again go to restaurants and cafes, parks and beaches and museums, and monuments. It was available on Apple’s App store and the Google Play store.
