""No contact tracing app can be fully effective until there is widespread, free, and quick testing and equitable access to health care,” said Jennifer Granick, surveillance and cybersecurity counsel at the American Civil Liberties Union. “These systems also can’t be effective if people don’t trust them. People will only trust these systems if they protect privacy, remain voluntary, and store data on an individual's device, not a centralized repository.”
“At the same time, we must be realistic that such contact tracing methods are likely to exclude many vulnerable members of society who lack access to technology and are already being disproportionately impacted by the pandemic,” Granick said. “We will remain vigilant moving forward to make sure any contact tracing app remains voluntary and decentralized, and used only for public health purposes and only for the duration of this pandemic.""
