Washington State now has a tool that can send an alert to your smartphone to notify you that you’ve been in contact with someone who has COVID-19.

In a statement released on Medium, the state writes that:

WA Notify uses privacy-preserving technology jointly developed by Google and Apple and works without collecting or revealing any location or personal data.

As with any app you need to download this feature and set up notifications.

Governor Jay Inslee said:

“We’ve deployed WA Notify in 29 languages so as many Washington residents as possible can protect themselves, their loved ones and their communities. I encourage everyone to start using WA Notify today so we can continue to work together to contain this virus.”
