Press Release

Wisconsin DHS has released a new tool to help stop the spread of COVID-19. The free WI Exposure Notification app uses Bluetooth technology to alert users of the app if they have been in close contact with someone who has tested positive for COVID-19.

The app exchanges anonymous Bluetooth keys with other smartphones nearby that also have the app. First, when a user tests positive for COVID-19 they receive a code that they can activate through the app. The app identifies users that were exchanging Bluetooth keys at the time of exposure and meet the criteria for a close contact (i.e. being within six feet of someone for more than 15 minutes). Then an anonymous exposure notification is sent to those users to notify them that they are a close contact. In order for the app to work, Bluetooth will need to be turned on.

You will need to download or enable the app for it to work. The app can be downloaded from the Google Play Store for Android users. iPhone users with iOS version 12.5 or later can take the following steps to enable the app:

  1. Go into settings
  2. Scroll down to exposure notifications
  3. Turn on Exposure Notifications
  4. Select United State>Wisconsin

There are safeguards in place to protect user privacy. The app does not link your identity or phone number with the Bluetooth keys that are exchanged. Your physical location or personal information is not collected through the app and will not be shared with Apple, Google, Wisconsin Department of Health Services or other app users.
