The app is designed to the highest standards of data privacy and data security. The app does not access or track your location. It only records your distance from other phones that have the NHS Test and Trace app installed. This data is held on your phone.
If you choose to use the venue check in function, your phone will hold protected data about which venues you checked into, and at what time.
The NHS and the government will not have access to any of this data. They cannot use the app to track your location, for law enforcement, or to monitor self-isolation and social distancing.
The app does record the following:
- Contact tracing data, including how long you're close to another app user and the date and time of these encounters. It records the signal strength of other anonymous app users’ Bluetooth to work out how far apart you are. Contact tracing data will stay on your phone for 14 days.
- Venue check in data. This is protected data about which venues you checked in to and at what time. This data never leaves your phone and is automatically deleted after 21 days.
- Your postcode district, which is the first part of your postcode before the space. Read more about how the app uses your postcode district.
For more information about the data used by the app, see the Privacy Notice.
