COVID Alert

COVID_Alert_Logo

COVID Alert is a mobile application developed to help mitigate the spread of COVID-19 by notifying users of potential exposure to the SARS-CoV-2 virus. The app uses Bluetooth technology to exchange anonymous codes with nearby phones, allowing users to be informed if they have been in close contact with someone who has tested positive for COVID-19.

Development and Launch

COVID Alert was developed by the Government of Canada in collaboration with provincial and territorial governments. The app was officially launched on July 31, 2020. It is available for download on both iOS and Android platforms.

Functionality

The app operates by using Bluetooth Low Energy (BLE) to exchange random codes with other phones that have the app installed. If a user tests positive for COVID-19, they can choose to upload their random codes to a central server. Other users' apps will periodically check this server and notify them if they have been in close contact with a positive case.

Privacy and Security

COVID Alert is designed with privacy in mind. It does not collect or share any personal information or location data. The app uses anonymous codes that change frequently to ensure user privacy. All data is stored locally on the user's device and is deleted after 14 days.

Adoption and Usage

The app has been promoted by various levels of government and public health officials as a tool to help reduce the spread of COVID-19. Adoption rates have varied across different regions, with some areas seeing higher usage than others.
