Governor Newsom Announces Statewide Expansion of CA Notify, a Smart Phone Tool Designed to Slow the Spread of COVID-19

Published: Dec 07, 2020

New digital tool will officially launch on December 10

SACRAMENTO – Governor Gavin Newsom today announced the statewide launch of CA Notify, a new digital tool that will help reduce the transmission of COVID-19. Starting Thursday, December 10, Californians can opt in to receive COVID-19 notifications informing them if they have been exposed to someone who has tested positive for the virus. CA Notify is a digital tool that protects privacy and security – it does not collect device location to detect exposure and does not share a user’s identity. The tool was developed in partnership with Google and Apple and piloted with the help of the University California, San Diego and the University of California, San Francisco.

Starting Thursday, December 10, Californians can enable CA Notify in their iPhone settings or on Android phones by downloading the CA notify app from the Google Play Store. Californians may start receiving availability alerts from their phones on Thursday, December 10.

When individuals voluntarily activate CA Notify, the tool uses Bluetooth technology to exchange random codes between phones without revealing the user’s identity or location. If a CA Notify user tests positive for COVID-19, they will receive a verification code to plug into the app, if they choose. Any other CA Notify users who have been within 6 feet for 15 minutes or more of the COVID-19 positive individual will get an anonymous notification of possible exposure. CA Notify will accelerate how quickly people get notified of a possible COVID-19 exposure, giving people the information they need to make responsible decisions around quarantine and testing. Users who have tested positive for COVID-19 will get a text from the California Department of Public Health at 855-976-8462 with a code which they can enter into CA Notify triggering an alert to phones of people who may have been exposed in the previous 14 days.

CA Notify is completely voluntary and free, and is designed to protect your privacy. It does not use device location to detect exposures and does not share your identity to other users. And individuals can securely report if they test positive, so that others can be notified of exposure without indicating their identity.
