StopCOVID NI Mobile App

This app, from our health service, tells you automatically if you’ve been near someone who tests positive for COVID-19.

How does the StopCOVID NI contact tracing app work?

If you are in close contact with an app user who has added a positive COVID-19 test result to their app, this app will notify you. You won’t know who, when or where.

If you test positive for COVID-19 you can add that result to this app. This will notify other app users that you have been in close contact with. The app will never reveal your identity or location.

How is my privacy protected?

If you test positive for COVID-19 you will get a code by SMS text message from ‘HSCresult‘. When you put that code into this app you will be asked to share the random IDs that your phone has been swapping with other app users over the last 14 days. If you agree, these ‘diagnosis keys’ will allow us to tell those people that they have been exposed to COVID-19.

So that you can use the app when travelling abroad we will securely share ‘diagnosis keys’ with other countries. This also means that apps used by visitors from those countries will work here.

The app will never track your identity or location, but it does collect some data. We will know the number of app users, the number of people in NI who enter ‘HSCresult’ codes, and the number of people in NI who are told that they have been exposed to COVID-19.

We need this data to prove that the app works, and to get it approved as a medical device.

To protect your privacy, and tell you as soon as possible if you’ve been exposed to COVID-19, we use automated processing. This means that no human is involved in the process, and some people are uncomfortable with that. To be able to use this app you will be asked to turn on ‘exposure notifications’. By doing this you are agreeing to the automated processing.

The app has been developed in line with expectations published by the UK ICO (Information Commissioners Office) who have published their recommendations here.

What technology is used?

The app uses technology developed by Google and Apple who are engaged in a joint effort to enable the use of Bluetooth technology to help governments and health agencies around the world reduce the spread of the virus, with user privacy and security central to the design.

Apple and Google have published details of this technology

This new technology is only available in the newest versions of the iOS and Android operating systems. For some users this will be a problem because the new operating systems are not supported on older iPhone models (iPhone 6 and earlier).
