What assurances can the First Minister give users of the new test and protect app that our contact information will be held securely and that privacy will be respected at all times?

I am getting a running commentary on download from the Deputy First Minister, who tells me that more than a quarter of a million people in Scotland have now signed up to the app, which is fantastic. I thank everybody who has done that, and I ask those who have not to please do so.

Privacy and confidentiality have been at the centre of the development of the app. I am not a technical expert but, in summary, the app does not track a person’s location; it generates random codes that tell whether they have been in contact with someone within 2m for 15 minutes or more. Those codes are retained for only 14 days, I think, but they allow people to be notified. There is no passing on of data; in fact, very minimal data is collected by the app. Of course, if you are told that you have been in close contact with somebody who has tested positive, you have no idea who that person is, and when the person who tests positive puts their testing code into the app, they do not know who will be notified. Anonymity, confidentiality and privacy are built into the app, and that is an important assurance for people.
