With TousAntiCovid, you are in control of your data!

TousAntiCovid does not require any personal information to be installed and run. The application can be uninstalled at any time and its use will never be made mandatory.

Exclusive local storage of your documents

As long as you do not declare yourself positive for Covid-19, the application checks the server to see if its own crypto-identifiers are among those available on the server and not the other way around.

Moreover, during a control on the national territory or when travelling, the competent authorities (authorised personnel, police) can access your certificates with the TAC Verif application. Only the authenticity of the certificate's signature is then verified by a dedicated server of IN Groupe (Imprimerie Nationale).
