FAQ Bluezone
What is Bluezone?
The app is to protect the community against COVID-19 pandemic, helping bring the life back to normal. Viet Nam’s Ministry of Information and Communications and Ministry of Health, under the direction by the Prime Minister, have deployed the app called “Electronic mask Bluezone” to smartphones.
Bluezone shall alert if you had close contact with people who have COVID-19, thereby minimizing the spread of the virus to the community, helping people return to their normal life.
When there is a new case of infection, you can learn whether you had close contact with this case or not simply by accessing Bluezone. The more people install Bluezone, there more effective it is. Let’s challenge the virus with the strength of our community. Let’s try to get every smartphone around Viet Nam installed with Bluezone in a month, so that our community will be protected.
With each person installing the app for themselves and getting the smartphones of 3 other people installed with Bluezone, in a month, the whole Viet Nam will get protected. The Ministry of Information and Communications and the Ministry of Health recommend that the whole country install Bluezone for themselves and for 3 others.
Why does Bluezone ask for access to photos, media and files?
Bluezone only uses "access to files" permission to write the history of "close contacts" on the device memory. Even so, according to Google policy, the device automatically recommends "allowing access to photos, media and files" even if Bluezone does not use the other permissions. You need to accept these to be able to record "close contacts".
Does Bluezone collect user locations?
Bluezone does not collect or use user location. When you install Bluezone on Android and activate Bluetooth, the device will ask for location permission, this is due to Google's policy which will automatically ask for location permission when turning on Bluetooth BLE. However, Bluezone does not use that permission.

Does Bluezone store user information?
Bluezone only stores data on users' devices, absolutely does not upload such data to the server, and does not collect location information. Bluezone only records when and how long two people meet, it doesn’t know where they meet. Bluezone users will remain anonymous by using the ID generated by the system itself.
Must the device always turn Bluetooth on?
For Bluezone to work properly, the phone must always turn on Bluetooth. However, Bluezone uses the Bluetooth Low Energy technology (BLE) to save battery, so users can feel secure to use it.
Is there any harm if the phone is always on Bluetooth in the community?
This is like using Wifi in the community because both Bluetooth and Wifi work on 2.4 GHz. Users can be completely secure to use it as normal.
If Bluetooth is on, can my phone be easily hacked?
Bluetooth is a connection standard that is widely used today and has proven to be secure.
What if the people don't have Bluetooth devices or they don't turn it on? How to monitor this issue?
Turning on Bluetooth is the right of each individual. In order to protect themselves and their community, the people should use Bluezone regularly. If users turn off Bluetooth, assuming they are in contact with someone infected with COVID-19, this contact will not be recorded. If the number of users is large enough, even those who do not use smartphones are also protected.
How will Bluezone handle the cases that do not use smartphones, for example the elderly?
When the number of users is large enough, the community will be protected including those who do not use smartphones.
Do infected people install this Bluezone? If they don't use Bluezone, how can there be data to find out people who have been in close contact with them?
In some cases, even if an infected person does not use Bluezone, but if he/she turns on Bluetooth, other devices that install Bluezone can still recognize the contact with that person.
Is this Bluezone practical, because not everyone turns on Bluetooth?
Turning on Bluetooth is the right of each individual. In order to protect themselves and their community, the people should use Bluezone regularly. If users turn off Bluetooth, assuming they are in contact with someone infected with COVID-19, this contact will not be recorded. If the number of users is large enough, even those who do not use smartphones are also protected.
Does this Bluezone drain the battery?
Bluezone uses Bluetooth Low Energy technology to save battery, so users can feel secure to use it.
Does Bluezone work in the background, or do I have to turn it on every time I go somewhere?
Bluezone will remain active even the screen is off. Please note that Bluetooth must always be on to ensure adequate contact recording. Bluezone uses Bluetooth Low Energy technology to save battery, so users can feel secure to use it.
In case there is data, will Bluezone have the function of signaling "you are approaching COVID-19"?
According to the rule, a person who has been identified as infected with COVID-19 will be put in quarantine and get treatment, so there is no way you can accidentally "get close" to such a person and Bluezone does not have this feature as well.
What solutions do other countries in the world use? What are the outstanding characteristics of Bluezone over these solutions?
In the world, Singapore, and DuBai also use BLE technology to control the contacts of the people. When using the software, the people must correctly declare their phone numbers and must be authenticated by health authoritities. Despite using the same technology, Android phone users will not have the data in contact with users of IOS phones and vice versa, resulting in limited accuracy of information.
With Bluezone, you only need to install it on smartphone and turn on Bluetooth, every contact will be recorded. Not only that, Bluezone does not require personal information, and it only stores data on the user's device, absolutely not on the server, and it doesn’t collect locations. Bluezone only records how long and when two people meet each other, but it doesn’t know where they meet. Bluezone users will remain anonymous by using the ID generated by the system itself.
Bluetooth is also the solution that Europe, the US and Singapore have started to research and apply in fighting against the COVID-19 pandemic, especially for the purpose of helping life return to normal after the peak of the pandemic. In particular, a week ago, two technology companies that own 99% of smartphone users in the world, Apple and Google, shook hands to jointly develop an app using Bluetooth BLE for fighting against COVID-19 pandemic. However, it’s not until the middle of May to have the first tests and it is expected for many more months to have actual products.
