The StopCovid application intended to limit the proliferation of the virus on French soil is now available for free download from the Play Store. Although its use is not compulsory, it is however strongly recommended by the public authorities. This tool could help prevent a second wave of coronavirus..
How StopCovid works
We are living in a very special time. Since the appearance of the coronavirus in late 2019 in China, several countries in the world have been subjected to total or partial containment. The movements of millions of citizens have been limited in order to stem the circulation of the virus.
To prevent a possible return of the epidemic, the public authorities have just unveiled the StopCovid application. The purpose of this tracking system is to track our movements and to be warned in the event of contact with a contaminated person, including in the case of strangers..
Once installed on your smartphone, StopCovid automatically saves the identifier (data anonymized using an encryption method) of all other users of the application located within a radius of less than one meter from you, for at least 15 minutes.
If one of the owners equipped with the StopCovid application is diagnosed positive for the coronavirus, his doctor will provide him with a QR code to scan with his smartphone. All the people he has encountered during the last 15 days will receive a notification so that they can be tested..
Important detail, its use is done on a voluntary basis. Unlike other countries, notably in Asia, the installation and use of the StopCovid application is not compulsory. Smartphones equipped with StopCovid are detected via the Bluetooth connection and not the GPS data. The application therefore does not geotag people.

The StopCovid application is now activated on your smartphone. Please note that the Bluetooth wireless connection remains active even when the screen of your smartphone is turned off. StopCovid performs tasks in the background. This may shorten the life of your phone.
