MI COVID Alert is the COVID-19 exposure notification app supported by the Michigan Department of Health and Human Services (MDHHS), in partnership with SpringML, Google, and Apple. This app uses Bluetooth Low Energy (BLE) API framework created through a unique collaboration between Apple and Google.

Your personal use of MI COVID Alert helps inform others of possible exposure to COVID-19 if they are suspected of having been within close proximity to someone who has tested positive. When you download MI COVID Alert, you are helping your community stay ahead of any potential surge in COVID-19 cases.

How MI COVID Alert Works:
Once downloaded, users of the app who have enabled it will exchange anonymous Bluetooth “keys” (random alpha-numeric codes that represent a Bluetooth signal) with other MI COVID Alert users.
If someone reports that they tested positive for COVID-19, the app will search for other users who shared the Bluetooth Low Energy (BLE) signal. The BLE signals are date-stamped and MI COVID Alert estimates how close the two devices were based on signal strength. If the timeframe was at least 15 minutes and the estimated distance was within six feet, then the other user receives a notification of a possible exposure. Names of users and locations of possible exposure are never tracked and never shared.

The BLE framework within MI COVID Alert will run in the background, even if the exposure notification app is closed. It will not drain the device battery at a rate faster than other apps that use normal Bluetooth and/or are open and running continuously.

How MI COVID Alert Protects Your Privacy:
MDHHS takes your privacy very seriously. This is why we chose to use the Apple and Google BLE framework. No personal data or location tracking occurs within MI COVID Alert.

MDHHS and local public health staff follow up with persons who have a positive COVID-19 laboratory report. Public health will provide MI COVID Alert users with a validation pin. That validation pin must be entered into the app to report a notification of possible exposure to other users. This prevents people from falsely reporting positive results, which could generate false exposure notifications.

If you have the current Apple or Google operating system installed on your device, you may have noticed that Exposure Notifications are now included. You cannot enable this function until you have downloaded MI COVID Alert. Apple and Google will delete the exposure notification service tools from their respective operating systems once the pandemic reaches a point that public health no longer requires the use of this technology.

Thank you for downloading MI COVID Alert! Together, we can protect our family, friends, and communities.

Protects Your Privacy!

The way these contact tracing apps work is actually quite interesting. Somewhat counterintuitively, its able to do its job effectively without violating your privacy.

It doesn't track your location, it doesn't know your name or anything about you, it doesn't know the identities of the people you've come into contact with, and it doesn't spread any information about who you are to others.

Very awesome to know that we can keep ourselves safe during a public health crisis without having to give up our privacy.

Needed it

Its been a long since other states have released similar apps. I have been waiting for this app because it could help notify people who have been in close contact with someone testing positive such as in the grocery store.

Doesn’t do the job intended - failed for me

I was at the Clinton Township mi clerks office on 10-21, stood in line went to several desks talked to three people at clerks office. The one who handed my ballot to me didn’t have a mask on.
I get home later that day turn on evening news to find that right after I left, it was discovered the clerk and other people who work there had Covid and didn’t report it. The office was shut down right around an hour after I left and is closed for next 5 days...during an election...and I was exposed having been there.

I waited for this app to alert me, I mean it was on the news! It’s reported! I was there for hours!
They closed the township offices due to it!

But this morning I looked...app still says “no exposures”. It is unreliable and just failed the most simple test. Who put this thing out?
