Exposure Notifications will help your government’s public health authority alert you if you’ve been exposed to COVID-19.

About Exposure Notifications

Google and Apple jointly created the Exposure Notifications System out of a shared sense of responsibility to help governments and our global community fight this pandemic through contact tracing.

Exposure Notifications on your smartphone enable contact tracing apps to send you a notification if you’ve likely been exposed to COVID-19. Contact tracing apps will be developed by your local public health authority, not by Google or Apple.

How this technology works

Public health authorities around the world are building apps that use the Exposure Notifications System to help their contact tracing efforts. You can find the app for your area (if available) in your app store.

Once you opt-in to the notification system, the Exposure Notifications System will generate a random ID for your device. To help ensure these random IDs can’t be used to identify you or your location, they change every 10-20 minutes.

Your phone and the phones around you will work in the background to exchange these privacy-preserving random IDs via Bluetooth. You do not need to have the app open for this process to take place.

Your phone periodically checks all the random IDs associated with positive COVID-19 cases against its own list.

If there’s a match, the app will notify you with further instructions from your public health authority on how to keep you and the people around you safe.

Designed to protect your privacy

We understand that the success of this approach depends on people feeling confident that their private information is protected. The Exposure Notifications System was built with your privacy and security central to the design. Your identity is not shared with other users, Google, or Apple. Learn more.
