The NHS COVID-19 app is no longer in use and the Isle of Wight trial has now ended. This is archived information from 18 June 2020. If you still have the app, please uninstall it.

The app only requires you to use a small amount of your data when you notify us of symptoms and request a test, or if you get an alert. The rest of the time it does not require a mobile or wifi connection.

Like most apps, a small amount of data is required to download the app initially.
