Citizen, the most trusted public safety app in the US, has introduced SafeTrace in partnership with San Joaquin County to help people know if they’ve been exposed to COVID-19, and to help cities and states track potential outbreaks in an efficient, scalable way.

Get alerted when you need to get tested. - If you’ve had meaningful contact with somebody who later tests positive for COVID-19, you’ll get a notification to get tested. If you test positive, anyone you’ve been in contact with recently will be notified.

Powered by Bluetooth. - Your Bluetooth information will be used to determine nearby contact with other SafeTrace users.

Private and encrypted. - All contact tracing data is private, encrypted, and is deleted after 30 days. And, if you decide to disable SafeTrace at any time, data will be deleted within 24 hours.
