Add your phone to the fight against COVID-19.

AlohaSafe Alert is a free, voluntary new service that helps slow the spread of COVID-19. It is the State of Hawaii’s official exposure notification app and has been developed in partnership with the Hawaii State Department of Health.

Download the AlohaSafe Alert app to get COVID-19 exposure notifications and help keep Hawaii safe and healthy – all while maintaining your privacy.

AlohaSafe Alert is:


You control whether or not you receive notifications (you can opt-in/opt-out anytime). Notifications are only triggered if minimum thresholds of exposure are met.


The app does not track your location. It anonymously keeps track of devices you’ve been in close contact with for the past 14 days. Google and Apple cannot see your identity, nor can anyone who receives an exposure alert should you test positive for COVID-19.


Anyone can download the app to their smartphone at no charge.

The app is a safe way to alert you to potential exposure to COVID-19 and help stop the spread of the virus.

How it Works

  • Download the AlohaSafe Alert app on the Apple app store or the Google Play store and run through the setup screens.
  • Your device, using Bluetooth technology, can now anonymously communicate with other phones. Devices running the AlohaSafe Alert app “ping” each other, measuring the strength of the Bluetooth signal and duration of interaction.
  • When your app senses a close contact, the two devices will exchange a secure, random, anonymous code. Location, name and any other identifiable information are never included.
  • If you test positive for COVID-19, you will be contacted by a Hawaii State Department of Health contact tracer. During your interview, let them know you have AlohaSafe Alert. You will receive a verification code to anonymously notify others who have been near you about a possible COVID-19 exposure.
  • For an exposure notification to be triggered, devices you were in proximity to in the past 14 days must meet a minimum threshold of exposure, which is a distance of 6 feet or less for a minimum of 15 minutes. The 15 minute threshold is cumulative, so a notification will be sent if you were in close contact with one or more positive individuals for a total of at least 15 minutes.

Exposure Notification

How do I alert others if I receive a positive diagnosis?

  • If you test positive for COVID-19, you will be contacted by a Hawaii State Department of Health contact tracer. During your interview, let them know you have AlohaSafe Alert. You will receive a verification code to anonymously notify others who have been near you about a possible COVID-19 exposure.

I know someone who got a positive result, why didn’t I get a notification from the app? How quickly will I be notified?

  • Exposure notifications require several criteria to be met in order to send a notification. The app must be installed on both devices, a minimum threshold of exposure needs to be met, and  the positive individual needs to upload a verification code they received from the Hawaii State Department of Health.

How quickly will I be notified if I have been exposed?

  • You will be notified once the COVID-positive individual uploads their codes with the contact tracer. You can be notified of any exposure that happened within the last 14 days.

Do I still need to talk to a Hawaii State Department of Health contact tracer? 

  • Yes. Because AlohaSafe Alert is 100% anonymous, the State will not be informed about your possible exposure to COVID-19. AlohaSafe Alert  is intended to complement traditional contact tracing  processes.


Does this work with visitors from other places?
