The NHSX coronavirus contact tracing app is being rolled out on the Isle of Wight this week, but major question marks still hang over the app. Matthew Gould, CEO of NHSX, told parliament today that the data collected by the app would be accessible to unspecified organisations as long as it was used for public health purposes. 

He said that, rather than only the NHS being able to access the data, other organisations with a legitimate public health reason might be able to as well – seemingly opening up the possibility for third parties to lay claim to the data. “I can’t give you a definitive list of exactly who would have access to the data,” said Gould. “But what I can say is, we will have proper procedures in place consistent with law that will make sure that only those who have an appropriate public health reason for seeing the data do so, and they do so under very clear conditions and criteria.”
