MD COVID Alert is the official COVID-19 Exposure Notifications Express system of Maryland. MD COVID Alert uses Bluetooth Low Energy technology to quickly notify users who might have been exposed to someone who tested positive for COVID-19 with the goal of reducing infections in Maryland.  iPhone users will be able to opt in by enabling exposure notifications in their phone’s settings and selecting Maryland as their region. Android can opt in by installing the MD COVID Alert app from the Google Play Store. MD COVID Alert is available at no cost and is voluntary. Users can disable exposure notifications at any time. 

Android users can download the app from the Google Play Store by following this link.

MD COVID Alert does not collect, transmit, or store personal information of users, and the system is completely anonymous.
