COVID exposure notification mobile app
Governor Walz announced the availability of a new COVID-19 exposure notification mobile application, COVIDaware MN, which could slow the spread of COVID-19 by helping Minnesotans protect themselves and their loved ones. The voluntary, anonymous application will alert a user if another user with whom they have had close contact during the virus’ infectious period tests positive for COVID-19.
When Minnesotans download the app and allow notifications, COVIDaware MN generates a random, privacy-protecting key for a user’s phone. The app does not track individuals’ locations or their positions relative to one another. Using Bluetooth Low Energy (BLE) technology, the user’s phone, and the phones of other users they are near anonymously exchange these privacy-protected keys.
If a person receives a positive test, the Department of Health will provide a unique code the person may enter into the app, if they choose. If they enter the code, users with whom they’ve been within six feet for 15 or more minutes over a 24 hour period in the past 14 days will receive a notification of an exposure.
COVIDaware MN will exchange random keys with anyone who downloads COVIDaware MN or similar applications developed by other states that use the same technology framework.
