<p>We have prioritised security and privacy at all stages of the National Health Service COVID-19 app’s development. An initial Data Protection Impact Assessment and a privacy notice have already been published on 7 May and, to ensure ongoing transparency, these will be updated as the app develops. A member of the Information Commissioner’s Office (ICO) staff has been working alongside the NHSX team since 23 March and the ICO’s most recent thinking on this matter is published and updated frequently on their website. The Ethics Advisory Board of the NHS COVID-19 app has published a letter to the Secretary of State summarising its advice in relation to the COVID-19 application. A copy of the letter is attached.</p>
