COVapp gives you the opportunity to participate in scientific research. When you have created an account (emailaddres and phonenumber for 2-step verification login), you can login and use the app. The app doesnt collect any personal information. You can fill in a daily diary (list of symptoms) and see information about the virus and see FAQ about it. When you start, you have to give your consent, else you cant fill in the daily diary and the app doesnt collect this data. The app does not collect any other data from your device, other then the you manually enter (symtpoms).
