In times of pandemic, we must do everything possible to minimize the problem. The Portuguese STAYAWAY COVID app, whose installation is voluntary, allows to identify, quickly and anonymously and by physical proximity, the networks of contagion by Covid-19. It then informs users that they have been in the same space as someone infected with the new coronavirus for the past 14 days.
Since the official launch, this application has been downloaded by more than 500 thousand Portuguese.
No, not many Portuguese have installed it yet, but it is a good start. According to the most recent figures, the STAYAWAY COVID application was downloaded by 535 thousand Portuguese. According to the information, in just three days, 7 users entered the code so that close contacts who have the application installed can be alerted.
Whoever is alerted does not know that they are infected, when they were infected or any other personal information. You simply receive an alert that you have been in contact with someone who recently tested positive for COVID-19.
Example of how the STAYAWAY COVID application works
Let's imagine that Pedro, Vítor and Francisco have the application installed and are going to have a coffee. Each of your phones will broadcast a random number every 10 minutes..
The other phones, which are listening, will record the numbers transmitted in their vicinity and also some data about the duration of the transmission and the strength of the signal they received. These numbers are deliberately large numbers, so the probability of two identical numbers spreading is very low.
Later, Francisco develops some symptoms and tests for COVID-19. If this test is positive, the doctor who validates the diagnosis provides Francisco with a 12-digit code. Francisco, if he wants, will insert this code in his application.
The latter, in turn, uses this code to deposit in a public repository the numbers (those that were generated at random) that Francisco issued in the last 14 days.
It is important to underline that all these steps are completely voluntary and that, although Francisco was assigned a code, it will be Francisco who decides to share his numbers or not.
Throughout this process, neither the personal data of the users nor any type of location data are associated with the random numbers disseminated.. So Pedro and Vítor know that they had a risky contact, but they don't know where or with whom.
In summary…
- STAYAWAY COVID app is safe
- GPS information is not used
- No contacts are identified, that is, the app labels are completely anonymous
- There is no record of the app having a negative influence on battery life.
- The application is a voluntary installation.
- No registration required
- The infected person can decide whether or not to alert other users.
