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.

Helppo työkalu koronaa vastaan

Haluatko tietää, jos olet altistunut? Tai haluatko pystyä varoittamaan muita, jos olet sairastunut? Jos vastasit kyllä, lataa tämä sovellus. Pysäytetään korona yhdessä!

Hyvä appi

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

Hyvä sovellus

Hyvä sovellus, joka ei näytä kuluttavan kovin paljon virtaa ja tietoturva näyttäisi olevan mallillaan.
