BERLIN — Better late than sorry.

That’s the spirit in which Germany — home to some of the world’s longest-standing privacy protections — launched a smartphone app on Tuesday that warns people if they have come into contact with someone infected with the coronavirus.

“The app we’re presenting today is unique,” said Helge Braun, who leads Angela Merkel’s chancellery and oversees Germany’s digital policy portfolio, as he presented the app. “Citizens can rest assured that we put high standards in place, both when it comes to data protection and cybersecurity.”

The German app, whose use is voluntary, analyzes short-range Bluetooth signals between cell phones to alert people who have been close to an infected person for more than 15 minutes.

The launch comes after governments around the world have rolled out similar tools to help contain the virus’ spread.

The promotional push aims to avoid a scenario like in neighboring France, where one week after Paris launched an application only 2 percent of all French people actively use it.

But Berlin, having watched similar efforts in other countries fall apart, has been determined to avoid such pitfalls by extensively testing its app for privacy and cybersecurity failings.

The government is also determined to convince Germans to download the app, with the country’s 30 largest companies on the Frankfurt Stock Exchange expected to publicly embrace it this week.

Stress testing

In order to prevent backlash over privacy concerns — which led Norway to suspend the use of its app earlier this week — Berlin took far-reaching measures.

Tuesday’s launch follows a two-month delay after Merkel’s government decided in late April to overhaul initial plans over a warning from hundreds of experts warning about privacy and cybersecurity shortcomings.

As a result, Berlin commissioned home-grown technology companies Deutsche Telekom and SAP to develop a new app from scratch.

Based on an approach championed by U.S. tech giants Apple and Google, the app does not save information from all users in one place. Rather, the vast majority of information collected by the app is stored on users’ phones and automatically deleted after 14 days — a solution privacy experts say is more effective, albeit not perfect, in protecting sensitive information.

To add another layer of security, the app encrypts the data it collects.

This design, privacy experts say, makes the German software less invasive than apps launched in other countries, some of which also access and analyze location data, GPS movement data or data collected by fitness apps.

Germany’s effort also stems from an unprecedented open-source collaboration. SAP and Deutsche Telekom regularly published their source code online, leading to more than 2,100 submissions with feedback from technology experts how to improve it, which were incorporated in the final design.

“There has never been a public project giving outsiders as much insights into its development,” SAP Chief Technology Officer’s Jürgen Müller said.

The next big goal is to get to a point at which different apps across Europe will be able to communicate with each other and trace potential infections, German officials stressed Tuesday.

The European Union’s coordination group of national health authorities announced they had agreed on how national apps could exchange data with one another to allow people to use them across borders.

Prevention

Germany, with a population 83 million, has recorded about 188,000 cases of coronavirus and fewer than 8,900 deaths — a relatively low number which experts attribute to widespread testing, a robust health system and a lockdown introduced in mid-March.

But as many restrictions have been lifted and the rate of new infections is slowly climbing again, tracking cases will be one key factor in preventing another large-scale outbreak, experts say. Officials believe Germany’s new contact-tracing app will help in that respect.

“With the app we can identify, with a certain probability, additional potential infections that previously slipped through the cracks,” said Lothar Wieler, who leads the Robert Koch Institute, Germany’s national disease center.

Health Minister Jens Spahn added that the use of the app would significantly speed up the time it takes until people are informed they might have been exposed to the virus.

“The app can help warn those who have been in contact with infected individuals more quickly than previously possible — and every hour counts in the fight against the virus,” he said.

The great challenge is to convince Germans to download and use the voluntary app.

In a recent survey, over 40 percent of all Germans opposed to using the app said they wouldn’t use it over concerns what will happen to their data.

“We’ve done everything within our power to ease those doubts,” SAP’s Jürgen Müller said.

On Tuesday morning, the country’s chief privacy watchdog, Federal Data Protection Commissioner Ulrich Kelber, gave the app his blessing, releasing a statement in which he called the safeguards implemented in the app’s design “sufficient.”

U.K. Prime Minister Boris Johnson announced a £120 million scheme to provide food vouchers for children during the summer, following a campaign by England and Manchester United footballer Marcus Rashford.

The government had originally said the scheme would not be extended during the six-week summer break, but had come under increasing pressure to change course.

Rashford had spent several days urging politicians to make sure pupils could continue to access the national voucher scheme — which was introduced in March to help poorer families feed their children when schools were closed because of the coronavirus. In an open letter to MPs on Monday, the Manchester United striker spoke of his experience of relying on free school meals and food banks.

“Owing to the corona pandemic, the PM fully understands that children and parents face an entirely unprecedented situation over the summer,” Johnson’s spokesperson said when announcing the “Covid summer food fund” for pupils in England, the Guardian reported. The support works out at about £15 a week per recipient and the vouchers can be redeemed at supermarkets.

“The prime minister welcomes Marcus Rashford’s contribution to the debate around poverty, and respects the fact that he has been using his profile as a sportsman to highlight important issues,” the spokesperson said.

“Just look at what we can do when we come together,” Rashford, 22, wrote on Twitter in response.

I don’t even know what to say.
Just look at what we can do when we come together, THIS is England in 2020.

Labour leader Keir Starmer said the move was a “welcome U-turn,” the BBC reported.
