How does it work?

Once you activate CA COVID Notify, it does all the work. All you do is keep your bluetooth on. You will only receive alerts if you were in close contact with someone who tests positive for COVID-19. Your privacy is protected as your identity is not known and your location is not tracked.

Imagine that two people have Exposure Notifications turned on. If they come within six feet of each other for 15 minutes or more within a day, their phones will exchange keys (randomly generated numbers) that log that close interaction.

If one person later tests positive for COVID-19 and agrees to share that information with CA COVID Notify, then the other will receive an alert that they have been exposed.

Participating campuses are: UC San Diego, UCSFH, UC Davis, UC Berkeley, Berkeley Lab, UCLA, UC Riverside, and UC Santa Barbara.

It depends on how many people you interact with, how many individuals use Exposure Notifications on their phones, and how many of them have a positive diagnosis. You can expect to get a weekly notification from the service confirming it is still running on your phone.

You will be notified once the COVID positive individual authorizes Exposure Notifications to send out an alert. How quickly you receive the notification will depend on when that person received a positive result and how quickly the information was uploaded. You can be notified of any exposure that happened within the last 14 days.

If you have exchanged keys with someone that has reported a positive diagnosis, you will receive a push notification to alert you. This notification will include instructions on your next steps and who to contact.

Your positive test result will only result in Exposure Notifications if you opt in and upload your result to the system. Even then, your personal information is not collected, stored or shared by the exposure notification system.

No. Your positive test result will only result in Exposure Notifications if you opt in and upload your result to the system.
