The application is useful for everyone as it will inform them whether
they have been in contact with an infected person, so they can take suitable action.
This means they can isolate themselves from vulnerable people with whom the course of the disease would be more problematic,
and they can identify their own symptoms more quickly and seek medical assistance.
The application is completely anonymous. A person’s identity is unknown to both the infected person
and to the person who receives the information that they have been in contact with such a person.
Neither does the person who receives the information that they were in contact with someone
know who that person was or at what precise time and at what location.
You only receive a message that you were in risky contact with an infected person, so please make sure that the infection
does not spread.
