Contact tracing app not sharing user data with police

It followed news that the contact details of people told to self-isolate by the NHS Test and Trace scheme would be shared with the police

The developers of the Covid-19 contact-tracing app for England and Wales have stressed that none of the data it uses will be shared with the police.

It followed news that the contact details of people told to self-isolate by the NHS Test and Trace scheme in England would be shared with the police “on a case-by-case basis”.

However, the app operates independently of this system.

The Covid contact-tracing app has been downloaded more than 18m times since it launched in September.

The news from NHS Test and Trace on Sunday led to worried app users taking to social media to say they would delete the app over privacy concerns.

The Department for Health and Social Care told the BBC that neither the police nor the government received any data from the app.

In a tweet, the official account for the NHS Covid-19 app said the app cannot be used to track your location, for law enforcement, or to monitor self-isolation and social distancing.

Recommendations to self-isolate which come via the app are not legally enforceable – unlike an instruction by phone call from NHS Test and Trace.

The app has been built so that not only is all the data it collects anonymised, but it also only exists on individual handsets.

By its very design the app’s data can’t be shared, it’s held locally on the phone, commented Prof Alan Woodward, a computer scientist from Surrey University. Even if the police did get hold of it, it’s all anonymised so it wouldn’t mean anything to them.
