Koronavilkku is now compatible with several European contact tracing applications

Publication date 8 Jan 2021

A new version of the Koronavilkku app has been released yesterday on the 7th of January. Version 2.0 enables data transmission between Koronavilkku and several other European contact tracing applications for COVID-19. 

A Koronavilkku user can now be notified of possible exposure even if the person reporting the infection uses another European contact tracing application. Similarly, if a user is diagnosed with coronavirus, they can share this information to other countries’ contact tracing applications if they wish.  

“Koronavilkku's compatibility with other applications helps to break transmission chains and prevents the epidemic from spreading even when application users travel between countries”, says Aleksi Yrttiaho, Director of Information Services at the Finnish Institute for Health and Welfare. 

Secure user privacy 

The person reporting their infection decides whether to allow sharing the information across borders. The user cannot be identified from the shared data. The data is sent through a secure gateway service produced and provided by the European Commission. The National Cyber Security Centre of the Finnish Transport and Communications Agency has assessed the system's data security.  

Provisions on the use and disclosure of the data are laid down in the Communicable Diseases Act. The current legislation allowing cross-border use is in force until 31 December 2021. 

On most phones, Koronavilkku updates automatically. However, we recommend that you make sure that the app has been updated. You can check by visiting the app store (Google Play or Apple App Store). 

Compatibility between applications in different European countries has been developed with EU funding. Currently, the compatibility area includes Germany, Italy, Ireland, Spain, Latvia, Croatia, Denmark, the Netherlands and Poland.
