STAYAWAY COVID is the official COVID-19 exposure notification app for Portugal. It runs on mobile phones and is intended to support the country in its efforts to screen for COVID-19. By monitoring your most recent contacts, the app allows you to know, simply and safely, whether you have been exposed to the disease. The STAYAWAY COVID app is entirely voluntary and free and at no time requires access to your identity or personal data.
Once installed, the mobile phone indicates its presence to all nearby devices using random identifiers, not disclosing any personal information. The information shared between devices allows STAYAWAY COVID to know the mobile phones one has been close to, how close and for how long. The World Health Organisation considers that an exposure within 2 meters and longer than 15 minutes to someone with COVID-19 presents a high contagion risk.
