Use the GuideSafe™ Exposure Notification app to anonymously share a positive COVID-19 test result — and be anonymously notified of your own possible exposure to someone who later reports a positive COVID-19 test result — all without sharing anyone’s identity. The app protects your privacy while giving you the power to protect your health, your family’s and your community’s.

Using the app is easy:

Step one: Download the GuideSafe™ Exposure Notification app and enable Bluetooth.

Step two: If you have tested positive for COVID-19, you can choose to report it. Your test will be verified by the Alabama Department of Public Health.

Step three: Those who may have been in close contact with you in the last 14 days will be notified they were near someone with a positive test, but they won’t know who or where. Your identity and location remain completely anonymous, and your personal information isn’t disclosed, no matter what.

Why it’s important

Stopping the spread of COVID-19 is essential to helping our communities, schools and businesses reopen and stay open. When someone tests positive for COVID-19, contact tracers with the Alabama Department of Public Health will help notify those the person has been near — but they won’t know every person’s close contacts. The more people who use the app, the better the ability to notify those who have been exposed.

How it works

When you are within about six feet of others, phones using the GuideSafe™ Exposure Notification app exchange encrypted, anonymous codes via low-energy Bluetooth. If you test positive for COVID-19, those with whom you came in close contact — defined as within six feet for at least 15 minutes over the last 14 days — will get an anonymous notification that they were exposed. The notification they get is completely anonymous — they will not know who tested positive, the time, or the location — only the date of the possible exposure.

Your privacy is our priority

The GuideSafe™ Exposure Notification app was developed by the Alabama Department of Public Health in cooperation with the University of Alabama at Birmingham and MotionMobs, using technology from a collaboration between Apple and Google. Users of the app exchange anonymous codes among their phones using Bluetooth — no location data is ever stored or exchanged, and your personal information is never shared.

What’s New

Spread the app, not COVID. For this version of the GuideSafe™ app, we've made some minor improvements to help you better understand exposure dates and what to do if you receive an exposure.

Privacy-preserving COVID contact tracing

This is the official Alabama Department of Public Health privacy-preserving Covid contact tracing app. Apple and Google teamed up to create a framework which preserves privacy, does not track your location, and yet can let you know if you may have been exposed.

At some point, Apple and Google will introduce this technology into the operating system, encouraging, but not requiring adoption.

This looks like a great implementation and is part of the way forward.

Great concept and needed tool - but does not work.

***Update*** My husband tested positive 2 days ago and immediately reported it on the app. I still show “no exposure” and he has reported 2-3 times to be sure it went through.

I am SO thankful for the work done on this app. I feel completely safe using it, no names or emails or any information needed - it just uses a low blue tooth signal to know when in range of the app on another device - if which the owner happens to develop COVID-19 and clicks that anonymously on the app then I’ll get an alert if I’ve been in that range in the last 2 weeks. This is a much needed tool to help safely interact and do day to day things like errands and work. I hope a lot of people use this app to help prevent community spread of Covid as restrictions loosen.

This is a good step

This is just another tool in the fight. If anyone has privacy concerns they need to read-up on Apple and Google’s mechanism for making this work anonymously. It’s very elegant and functions in a way which makes it nearly impossible identify or track users. Don’t just trust me, read what the privacy researchers and encryption engineers have to say about it.
