Get DC's free DC COVID Alert Notice (DC CAN) to help protect your community while protecting your privacy.
How It Works
STEP 1Let's get started:
- For Android devices, you can find the app on Google Play. Android users will also receive a notification from the Play Store.
- For iPhones, opt-in to Exposure Notifications in your device settings.
STEP 2Once 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.
STEP 3Your 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.
STEP 4Your phone periodically checks all the random IDs associated with positive COVID-19 cases against its own list.
STEP 5If there’s a match, you will receive a COVID-19 exposure notification, with further instructions from DC Health on how to keep you and the people around you safe.
