Tell everyone you know about it. This app is available for iOS and Android phones and the more people that use it, the safer we are.
How long does it take to download and set-up?
It takes less than five minutes to download and set-up the app as long as you are on a network. Because Guam Covid Alert does not ask for any identifiable information, the user only needs to enable exposure notifications to run in the background. No account needs to be created, as this information isn’t needed to protect you or your community.
How does it work?
You download the app from Apple App Store or Google Play to your phone and opt-in to the notification system and turn on bluetooth. From there, it assigns your phone a privacy-preserving “random key” that changes every 10-20 mins. As you go about your day, your phone exchanges these anonymous keys with other phones to track exposure to one another.
If you test positive, you will be given a verification code from DPHSS.. After entering the code, you can choose to upload the list of the keys your phone has sent out in the last 14 days to our secure cloud server. This list of keys is not identified by any personal information about you. It simply is an anonymous list of numbers. Once a day your phone and everyone else’s phone will download the list of all the keys from people who tested positive. The keys will be compared and if there is a match, meaning if you were near someone in the last 14 days who has tested positive, you will receive a notification that you may have been exposed.
The notification will include suggestions for what you can do to help protect others in your family and community.For example – staying at home for 14 days. You can protect others from infection which plays a large part in revitalizing our economy.
How is my privacy being protected?
These randomly generated keys are stored on your phone, you choose to share them, if you are diagnosed. You are in control of this information. No other information is collected or shared by the app. You will never be contacted by Public Health because of a notification on the app. Google and Apple made it so anonymous that none of this information exists in the app. Any contact you receive from Guam DPHSS is based on the laboratory reporting and traditional “manual” contact tracing through interviews.
How does Guam Covid Alert protect my privacy?
The information the app exchanges with other phones is a simple anonymous number called a key. In addition, the app is very limited in what it does. Specifically, Guam Covid Alert:
- Never requires personal information such as your name or address
- Never tracks your location
- Never sends information to the government without your direct permission
- Never sends information to Apple or Google
- Never accesses other information on your phone
Will Apple and Google collect information about me from Guam Covid Alert?
No. Apple and Google will not collect any information about you from the Guam Covid Alert app.
How do I know that you aren’t tracking me and my whereabouts?
Google and Apple began working together to ensure that they could stop the pandemic by having phones talk together through random generated keys, but not able to share any personal information. To ensure this transparency the code has been developed as public, open source code so all developers have visibility into the functionality and data collected (only keys).
What data does this app collect?
The app preserves an individual’s privacy and does not ask for any personally identifiable information, like a person’s name, email or phone number. Using clever cryptograph, users’ generate sets of keys that rotate at different frequencies that are hard to decipher. These randomly generated keys are saved for 14 days on your phone and then deleted. No location or personal information is shared. The exposure notification alert will share some information about the exposure – like approximately how long you were exposed. Nothing more.
How do users obtain the test verification code?
If a user has an onset of symptoms and is tested, depending on the results (positive, likely, or negative), the health authority generates a code for them.
What happens after a user enters the verification code?
Depending on whether the code indicates a confirmed positive, a likely positive test, or a confirmed negative test, the user will be provided with guidance about what next steps to take, provided by the Department of Public Health and Social Services (for example, quarantine, schedule a contact-tracing interview, continue taking one’s temperature, etc.).
Is there an expiration date for each verification code?
Yes this time is set by DPHSS. If your code is expired, please reach out to DPHSS to get a new one.
