What is the purpose of TousAntiCovid?

Identifying and isolating Covid-19-infected people, alerting people who have come into contact with sick people is a major challenge in stopping the spread of the virus. The application initially named StopCovid has been developed for this purpose: notify, while guaranteeing anonymity, those who have been close to a person tested positive in Covid-19 so that they can be tested in turn and confined if necessary.

The National Commission of Informatics and Freedoms (CNIL) reviewed the evolution of the application on October 23 after having given a favourable opinion to the launch of the application StopCovid on 24 April 2020 and its conditions of implementation in a notice of 26 May 2020. The CNIL considers that the application is sanitarily and proportionate, with regard to the protection of our freedoms and our personal data.

How does the application work?

Downloading the application « AllAntiCovid » on its smartphone and its use is done on a voluntary basis. Installation is therefore not mandatory and is free.

Once installed and enabled (Bluetooth enabled and notifications accepted), the application sends an alert to users who have recently been in contact with a person who voluntarily declared that they had tested positive to the coronavirus during:

  • 5 minutes to less than 1 metre;
  • 15 minutes between 1 and 2 metres

The person will then be able to consult his/her doctor to be screened quickly, to be confined to waiting for the results and to isolate himself/herself if the test proves positive in order to break the transmission chains of the virus. In case of positive result , the care and conduct to be taken shall be explained to him.

In order to protect the unknown persons he may have known, a « AllAntiCovid » having just tested positive to Covid-19 can voluntarily declare it in the application by entering a code transmitted by his doctor or the laboratory. An alert will then be sent to all users who have been in close contact with him the previous days.

Data transmitted and privacy

The application « AllAntiCovid » uses the Bluetooth signal to detect a smartphone nearby and does not use GPS tracking of people. It will not be able to tell where a person has gone.

The data transmitted is completely anonymous. The identity of the application user cannot be known. It does not have an authentication system at installation time. The application « AllAntiCovid » generates only pseudonyms that are not associated with an identified person. They are stored temporarily (15 days) on the smartphone and transmitted to other smartphones in the immediate vicinity.

The application « AllAntiCovid » is temporary, it is not destined to continue after the health crisis.
