CA Notify is the official COVID-19 exposure notification app endorsed by the California Department of Public Health (CDPH). The app, created in collaboration with Google, Apple, the California Department of Technology, and the University of California, is designed to help slow the spread of the virus. By utilizing the Google Apple Exposure Notification API, CA Notify supports the State's COVID-19 prevention program as well as local contact tracing efforts.
The app is voluntary and free to use. Its effectiveness is directly linked to the number of people who install and activate it. Once installed, the app exchanges anonymous keys with other devices using Bluetooth technology. The keys are long random strings of characters that do not contain personal information. The app records the duration, date, and signal strength of the exposure to estimate the distance between the devices. The keys are only kept on the user's own device to ensure privacy, and they are deleted after 14 days.
If a user tests positive for COVID-19, they can activate the notification function in the app using a verification code. Other users who came in close contact with the infected person for 15 minutes or more within six feet will receive a notification of possible exposure. The app provides guidance on what to do next.
To prevent false positive reports, users must use the verification code to report a positive result via the app. The California Department of Public Health wants users to trust that any exposure notification they receive through the app is verified.
The app is designed to protect users' privacy and does not collect personal data or track location. The CA Notify Privacy Policy is available at https://canotify.ca.gov/privacy.
Laboratory results for all individuals who test positive for COVID-19 are routinely sent to public health authorities to support disease control activities such as case investigation and contact tracing. This process is independent of the app.
By downloading and activating CA Notify, users can help their family, friends, and community stop the spread of COVID-19.
