Confidentiality and data protection are an integral part of the basic philosophy of SocialPass. The solution is of course much more confidential than paper lists which are visible to everyone! When installing SocialPass, your data remains on your phone and is not in the cloud. The information about your presence in a location is stored on a server in Zurich, Switzerland for 14 days and is then automatically deleted. Only the cantonal doctor can access or request that the details be transmitted to him/her if he/she deems it necessary. All information is encrypted with a 256-bit key. They cannot be read, including your Qrcode. No data is used or shared for advertising purposes.
