CO Exposure Notifications is the official Exposure Notifications app of Colorado and the Colorado Department of Public Health and Environment. Exposure Notifications is a voluntary new service developed in partnership with Google and Apple to help slow the spread of COVID-19. No GPS, location information or personal identifiers will ever be collected, stored or shared by this service.

CO Exposure Notifications can quickly notify you if you've likely been exposed to COVID-19. Knowing about a potential exposure allows you to reduce the risk to your family, friends, neighbors and community.

By enabling Exposure Notifications, whenever you are within 6 feet of someone for at least 10 minutes, both phones will exchange secure, anonymous tokens using Bluetooth. If another user you’ve been near tests positive for COVID-19, they can upload their result to the app which will send a push notification to you and anyone else their phone has exchanged tokens with recently, notifying you to a possible exposure.

If you test positive, you can easily and anonymously notify others to help stop the spread of COVID-19.
