The companies Apple and Google only want to support one app per country that warns that you are near someone with corona.
They want that restriction so that as many people as possible in each country can use the software. It must prevent a patchwork of apps.
The companies help app developers build programs for iOS (Apple) and Android (Google) operating systems.
The goal is to anonymously warn users if they have come into contact with a person infected with the coronavirus.
The companies say they decided to build a contact tracking system because governments had tried to build their own apps, but turned to Apple and Google for help.
The companies emphasize that apps that use the technology must be built by public health authorities.
They also require user consent, are allowed to collect only the minimum amount of data, and are not allowed to register a user’s location.
