COVID-19 is scary because we don’t always know who has it.
So, in addition to wearing a mask and taking other protective safety measures, download Delaware’s new official exposure notification app — COVID Alert DE — to your smartphone.
The app is free. It notifies you if you’ve been exposed to someone who has the virus (within 6 feet for 15 minutes or more) and provides step-by-step instructions on what to do.
But it never reveals your identity. You remain completely anonymous.
How the app works
The COVID Alert DE app was co-created by Google and Apple, and works in the background of your phone, so it doesn’t interrupt normal use. COVID Alert DE uses random Bluetooth keys that change every 10-20 minutes.
Once downloaded, phones with the app share these random keys anonymously if they are in close proximity.
Positive COVID-19 app users upload a special code, which allows the keys on their phone to be checked against the list of random keys they were near in the past few days.
If there is a match, COVID Alert DE alerts that individual app user by sending an alert to their phone.
Additionally, the app asks how you’re feeling each day and about any symptoms you may have. You choose what information you want to share — or not.
The app then offers you advice based on any symptoms, such as quarantining and getting tested, and it records your check-ins for up to 28 days so that you can review them or talk with your provider.
It’s that simple.
How it protects your identity
The app does not track you or your location, so your identity is always safe.
No one knows who you are, where you are, or what you’re doing.
The app only recognizes other phones that have the app, and whether another app user has tested positive for the virus.
Armed with this knowledge, you can take action to protect others in your family or community — and feel good about slowing the spread.
The more who download, the more it protects
It just makes sense. As more people download the COVID Alert DE app to their phones, more phones will be able to interact.
It’s a safer, smarter way to alert people they’ve potentially been exposed to someone who has the virus, without revealing the identity, location or movements of anybody.
Delaware isn’t the only state to officially adopt and use a notification app successfully.
Alabama, Arizona, California, Colorado, North Dakota, Oregon, Pennsylvania, North and South Carolina, Virginia, Washington and Wyoming are among the latest to join the growing list of states that have made, or will make, the app available to the public to slow the spread of COVID-19.
