SwissCovid is the official contact tracing app of Switzerland.
Note: Visiting the "SwissCovid Leitfaden" leaves the SwissCovid app and enters a website. The dates of the possible infection will be passed to this website, but no additional data is passed from the app to the website. Visiting the "SwissCovid Leitfaden" may allow a network traffic observer to detect that someone received an exposure notification. Also a telephony traffic observer might be able to observe the same information when the Swisscovid Infoline is called.
