The more people use the app, the more effective it will be in curbing transmission.

The COVID Alert app runs in the background on your device without hampering or interrupting your day-to-day activities.

  • The app uses Bluetooth on smartphones to determine how far away you are from other people using the app.
  • It exchanges random codes every five minutes with app users nearby. The random codes cannot be used to identify you or to determine your location.
  • The app stores the codes on your telephone for 14 days.

Every day, when your device connects to the Internet, the COVID Alert app will match your random codes and those of individuals who have indicated through the app that they have tested positive.

Even if the app finds matches, it is impossible to link them to individuals. Your identity remains confidential.

If the app finds matching codes, this means that within the past several days, you have been less than 2 metres away for more than 15 minutes from an app user who has in the meantime tested positive. You will, therefore, receive an exposure notification.

  • The notification will indicate that you have potentially been in contact with COVID-19.
  • It will indicate the steps to follow.

No personal information or location data is shared. It is, therefore, impossible to know when and where you were in contact with an infected individual.

If you have tested positive and public health authorities have contacted you, you can request a one-time key. Informing other users that you have received a positive result is entirely voluntary. It is your decision to request a one-time key and to share your diagnosis.

To do so:

  • promptly call the telephone number indicated in the app;
  • make note of the key that you receive once your identity and test result have been verified;
  • enter the key in the app within 24 hours, after which it will expire.

Please note that only persons who have received a call from public health concerning a positive diagnosis on the COVID-19 screening test may be given a one-time code. A verification will be done by a staff member and you will be asked for identification information.

If you are not fully satisfied with the services provided when you request a one-time key, you may communicate with the official responsible for complaints at the following email address: Your complaint will be handled with full confidentiality.

Even if you choose to communicate your positive result, COVID Alert will not share any information that can identify you. You are in charge of making your own decisions. It is up to you to decide if you wish to share this diagnosis. Your anonymity will always be maintained.

If you receive a notification, this will mean that in the last several days, you have been near a person who had COVID-19, and who authorized the app to notify other users confidentially.

A notification does not mean that you have been infected with COVID-19.
