What is WI Exposure Notification?

WI Exposure Notification is a smartphone app that uses Bluetooth Low Energy technology to help stop the spread of COVID-19 in Wisconsin. Once you activate the app, your phone exchanges anonymous signals with other phones that are near it for at least 15 minutes. If somebody who has the app tests positive for COVID-19, they can then send an alert using the app to those other phones. This will allow people who are close contacts to quickly get the care they need and avoid exposing others to the virus.

DHS is committed to protecting your privacy. WI Exposure Notification does not gather:
