Alaska Covid ENX

Alaska COVID ENX (also known as Alaska COVID Exposure Notifications) was a free tool that worked on smartphones to alert users if they may have been exposed to COVID-19 without sharing any personal information. It is completely private and doesn’t know who you are or track where you go.

Thank you for using Alaska COVID ENX.

Together we helped to slow the spread of COVID-19 in Alaska. Alaska COVID ENX was installed on approximately 200,000 devices and generated about 70,000 anonymous exposure notifications to alert others of possible exposure to COVID-19.

Alaska COVID ENX and many exposure notifications applications across the country will be discontinued on May 11, 2023, when the Public Health Emergency ends. Beginning May 11, 2023, your phone will no longer notify you if you were near someone who tested positive for COVID-19. Your privacy is protected, and no GPS location or personally identifiable information was collected or stored. 

We encourage you to continue to follow the Alaska Department of Health COVID-19 guidance:

How does it work?

Alaska COVID ENX is an innovative, collaborative system developed by Apple and Google that uses the Bluetooth technology on smartphones to exchange anonymous “pings” between users. If an individual later tests positive for COVID-19, Alaska COVID ENX automatically and anonymously notifies the other pinged users of their possible exposure. This empowers Alaskans to act quickly if they come into contact with an individual who tested positive for the virus, slowing down the spread of the virus in the community.

The system is anonymous and is opt-in. No locations are tracked. It doesn’t know your name and your identity will never be revealed to anyone. The service will never collect, transmit or store any of your personal information.
