In the end of year 2020 Finland shall join to the European Federation Gateway Service. The purpose of the processing in the European Federation Gateway Service is to facilitate the interoperability of national contact tracing and warning mobile applications within the federation gateway and the continuity of contact tracing in a cross-border context. For interoperability purposes participating countries act as joint controllers. This means that the designated competent national authorities or bodies of the participating EU/EEA countries control the operation of the European Federation Gateway Services together. The technical and organisational details of this cooperation are laid down in the Commission Implementing Decision (EU) 2020/1023 of 15 July 2020, which is available here:

2. Purpose of processing personal data
The mobile contact tracing app to help to break chains of infection (hereinafter the ”app”) is a System of Systems consisting of a mobile app, its back end system and a professional user interface. The purpose of the app and the processing of personal data processed by it, is to identify the close contacts of app users and to alert close contacts of potential exposure to the covid-19 coronavirus. Use of the app is voluntary.
If an app user is diagnosed by a healthcare professional as having covid-19 infection, the user receives a single-use unlock code that the user can tap into the app at their own discretion. This allows other users of the app to be notified of potential exposure to coronavirus. The information does not allow users to identify persons infected with or exposed to the virus.
If the app sends the user an alert of potential exposure, the user can, at their own discretion, report potential exposure to a healthcare professional via the Omaolo health check service or by phone. The app does not automatically send information about exposure to healthcare professionals or other authorities. The Contact Point for Cross-Border Health Care can be found here:
The Koronavilkku app shall query visited countries for the purposes of European interoperability. As an additional safety measure, user consent is also obtained before the necessary data is sent through the Federation Gateway Service to participating countries. THL shall receive data for cross-border interoperability through the gateway.
It is not possible to identify person from exchanged data and each participating country is responsible for lawful processing of data. Countries follow EU cross-border interoperability procedures that enchant your privacy rights and ensures lawfulness of data processing. National data protection authorities supervise that personal data processing is done in lawful manner.
Personal data is processed in the Koronavilkku mobile app in iOS and Android interfaces, the Koronavilkku app back end system, in professional user interfaces and systems participating interoperability through European Federation Gateway Service.
Professional credentials can be used in normal workstation software and in secure email.
The back-end system is located in the IT processing environment provided by the Social Insurance Institute of Finland (Kela).
The professional user interface is located in the IT processing environment provided by SoteDigi Oy.
