How will the COVIDSafe app work?
A user voluntarily downloads the app from the app store. The user registers to use the app by entering a name, phone number and postcode, and selecting their age range. They will receive a confirmation SMS text message to complete the installation of the app. On the basis of this information, an encrypted reference code is generated for the app on that phone. That code is changed every 2 hours to make it even more secure.
The app uses Bluetooth to look for other devices that have the app installed. It takes a note when that occurs, securely logging the other users’ encrypted reference code. The date and time, distance and duration of the contact are generated on the user’s phone and also recorded. The location is not recorded.
This information is securely encrypted and stored on the phone.
The app uses a rolling 21 day window to allow for the maximum 14 day incubation period, and the time taken to confirm a positive test result. The rolling 21 day window allows the app to continuously note only those user contacts that occur during the coronavirus incubation window. Contacts that occurred outside of the 21 day window are automatically deleted from the user’s phone.
The contact information on the phone is not accessible by anyone (including the user of the phone), until the user is diagnosed with coronavirus and they upload the contact information to a highly secure information storage system.
The uploaded information enables state or territory health officials to contact the user and close contacts to provide advice on actions they should take to manage their health.
This cycle continues if a user of the app who was a close contact subsequently tests positive.
What will the app do?
The COVIDSafe app will allow state and territory health officials to contact you if you have been in contact with someone with COVID-19 (coronavirus). They tell you:
- what to look out for
- whether you need to quarantine
- how, when and where to get tested, and
- how you can protect yourself and your family and friends
If you become infected with coronavirus, the app will assist state and territory health officials to notify people with whom you have had close contact and advise them about self-quarantine and getting tested.
This will speed up current manual processes and make it quicker to stop the spread of the virus, particularly if restrictions are eased.
The app operates on a person’s phone as they go about their day.
It securely logs the encrypted reference codes of devices of other people who are using the app who have been in close proximity to you.
The close contact information can only be accessed by relevant health officials if there has been a positive case to help alert those who may need to be tested.
The app will never track your location.
Is there a risk that people may report false positives?
Information collected by the app that is uploaded to the highly secure information storage system will only be accessed by state and territory health officials once a user has a positive diagnosis. This positive diagnosis must be verified by health officials.
Who is a ‘close contact’ for notification purposes?
State and Territory public health officials will have the contact information for other users who have been within approximately 1.5 metres of the infected user for 15 minutes or more.
How does the app know a ‘close contact’ has occurred?
When 2 (or more) app users come into close proximity their phones exchange Bluetooth signals and make a series of ‘digital handshakes’.
The app records the encrypted reference code, time and proximity of 2 users, through the strength of the Bluetooth signals. This allows the approximate distance between the users and the duration the contact occurred to be determined once the data is uploaded to the highly secure information storage system.
The proximity for a close contact is approximately 1.5 metres, for a period of 15 minutes or more.
To be effective, users should have the app running in the background of their phone whenever they are coming into contact with people. Users of the app will receive daily notifications to ensure the app is running.
Why does the app only notify close contacts in the last 21 days?
The average incubation period for someone who contracts COVID-19 is typically 5 to 6 days, however the World Health Organization currently estimate that the incubation period can be up to 14 days.
The app uses a rolling 21-day window to allow for the maximum 14-day incubation period, and the time taken to confirm a positive test result.
The rolling 21-day window allows the app to continuously monitor only those user contacts that occur during the coronavirus incubation window.
Contacts that occurred outside of the 21-day window are automatically deleted from the user’s phone.
What information is captured by the COVIDSafe app?
The app only uses the information that’s needed to alert close contacts and allow health officials to make contact with them.
This information is only the encrypted reference code, date, time, duration and proximity of contacts.
At registration, the user provides their name, phone number and postcode, and selects their age range, which generates an encrypted code
All further information about contacts collected by the app is encrypted and stored within the app on the phone. Users cannot access contact information stored on their phone.
If the user deletes the app, all contact information is deleted.
The contact information on the phone is not accessible by anyone, unless the user is diagnosed with coronavirus and they upload the contact information to a highly secure information storage system.
Can a user or health official view the information stored on the phone including the contact log?
No. All information that is stored on the phone is digitally encrypted and cannot be accessed or viewed by any users or health officials.
Contact information older than 21 days on your phone is automatically deleted.
Can the app be used to track a user or contact?
No. It does not record an individual’s location or movements. The app only records that a contact occurred to allow health officials to contact those users to enable them to quickly self-quarantine and/or seek medical attention.
The app cannot be used to enforce quarantine or isolation restrictions or any other laws.
Commonwealth and state/territory law enforcement agencies will not be allowed to access any information from the app, unless investigating misuse of that information itself.
Do I have to use the COVIDSafe app?
No. Its use is entirely voluntary but using it will help save lives.
For the app to work, it must be running in the background on your phone. Other apps can be used at the same time.
You can delete the app from your phone at any time. This will delete all the app information from your phone.
At the end of the Australian pandemic, users will be prompted to delete the app from their phone. This will delete all app information on a person’s phone. The information contained on the highly secure information storage system will also be destroyed at the end of the pandemic.
If a user receives a close contact notification, will they be advised who the contact was?
No. This will operate in the same way as existing contact processes run by State and Territory health officials.
A phone call will be made to users who have had close contact with another user once that user is independently confirmed as having COVID-19. This phone call will be made by State or Territory health officials.
Close contact information is only available to State and Territory health officials once a user is confirmed as coronavirus positive, and the user securely uploads the information stored on their phone.
These calls will only be made to close contacts that have occurred in the 21 days before the information has been uploaded. This early notification allows users to quickly self-quarantine and seek medical attention.
Why should I use the COVIDSafe app?
Receiving early notification that you may have been exposed to coronavirus means you can be tested or go into quarantine, so your health and others’ is protected.
Without the assistance of technology, finding people who may have been exposed to the virus relies on people being able to recall who they have been around and knowing the details of every individual they have been in close contact with. In many cases, we don’t know the names and contact details of those we’ve been in close contact with (for example, at the supermarket or on the train).
The COVIDSafe app uses technology to make this process faster and more accurate.
The COVIDSafe app has been developed to ensure your information and privacy is strictly protected.
