Coronalert application

The Coronalert application is an initiative of the Belgian authorities. This free app for your mobile phone is an additional tool in the fight against the coronavirus (Covid-19).

Users of the Coronalert app:

  • find out if they have been in close contact with another Coronalert user who tested positive for the coronavirus, without knowing who it is
  • anonymously warn their close contacts when they themselves test positive for the coronavirus
  • together ensure faster contact tracing
  • help to stop spreading the virus


Coronalert never contains information about:

  • your identity
  • the people you have met
  • the locations you visited
  • people who test positive for the coronavirus
