Koronavilkku is Finland's official coronavirus application, which aims to prevent the spread of COVID-19. Your privacy is strongly protected. The Finnish Institute for Health and Welfare is responsible for the app.

Koronavilkku looks for nearby phones that have the same app installed. If someone you have previously met reports via Koronavilkku that they have COVID-19, you receive an exposure notification. If you are diagnosed with COVID-19, you can report this anonymously using the app.

The app is intended for all ages. If you are a minor, talk to your guardian before downloading the application.


The use of Koronavilkku is voluntary. You can stop using the app at any time by removing it from your phone.


- Data about encounters collected by the app is only stored on your device. The saved data will be deleted after 21 days or when you uninstall the application.
- Your identity is encrypted using random identification codes.
- The app does not collect location data.

What’s New

Version 2.3.0

In order to function, Koronavilkku needs permission to display notifications. After updating, open the app and make sure "Koronavilkku is active" is displayed in the home view.

The application now uses a new version of the exposure notification system. This improves the accuracy of identifying potential exposures. In addition, instead of estimating an individual encounter, the total risk of encounters that have occurred during the same day is calculated. The update will also speed up the delivery of exposure notifications, as data can now be delivered six times a day.

Hyvä appi

Joku sanoi, että ei voi vaihtaa kieltä. Mene puhelimen asetuksiin (hammasratas) ja etsi sieltä Koronavilkku listasta. Siellä voi vaihtaa kielen.

Iphone 6

Tätä ei pysty lataamaan iphone 6 tai vanhempiin malleihin koska niihin ei ole päivityksiä enään nii kuin uudenpiin.
