How is my privacy protected?
The WI Exposure Notification app uses Google and Apple Exposure Notification
technology which has built-in safeguards for user privacy. The keys exchanged
with other smartphones are not linked to your identity or phone number, and
change every 10-20 minutes.
The WI Exposure Notification app does not collect or store physical location or
personal information. Neither location nor personal information will be shared
with the Wisconsin Department of Health Services, Google, Apple, or other app
users.
Do I have to use WI Exposure Notification?
No. The use of the WI Exposure Notification app is entirely voluntary and you
may opt in or out at any time.
How does the app know if I have COVID-19?
Users who test positive for COVID-19 will receive a text notification with a link
that when clicked, will provide the user with the ability to notify close contacts.
Your identity will not be shared with these contacts.
Will my identity be shared if I test positive?
No. The only information that will be shared with other users if you test positive
and enter your code is the date of their exposure. We need to tell people this date
so they know how long to self-quarantine.
How does the app identify close contacts?
The app only exchanges randomly generated keys with smartphones that
approximate the current criteria for close contacts (i.e., being within
approximately six feet of someone with COVID-19 for more than 15 minutes in a
day). The randomly generated keys exchanged with other smartphones are
stored and periodically checked by your phone for a link to a positive COVID-19
case. If a match is found on a contact within the previous two weeks, an
exposure notification is sent. Again, smartphones will only send the keys to other
phones that all have the app installed.
How quickly will I be notified if I’m identified as a close contact?
If an app user you have been in close contact with gets a positive COVID-19 test
result, how quickly you will be notified depends on how quickly that person uses
the app to trigger notifications to close contacts. Users who qualify as close
contacts will be anonymously notified within a day of the code submission. You
will be notified of any close contact exposure that happened within the previous
two weeks.
