Law enforcers with court warrants could access data from Hong Kong’s Covid-19 risk exposure app for crime detection purposes, according to security and legal experts, despite officials stressing it would only be used for contact tracing.

While concerns about possible abuses of the app resurfaced after officials announced that patrons of restaurants and some other venues would be asked to use it from Thursday, analysts said the information could only be accessed if it was stored by a third party, and the court would apply the same stringent standards it did for other devices that stored personal data when handling warrant applications.

The Office of the Government Chief Information Officer on Tuesday also reiterated that records of the “Leave Home Safe” app were only stored on users’ devices, while warning the public against downloading fake programmes with similar interfaces.

Officials on Tuesday announced the easing of strict social-distancing rules from Thursday including allowing restaurants to offer dine-in services until 10pm, while cinemas, massage parlours, gyms and theme parks will also be allowed to reopen. But patrons must either use the app to record their visits or otherwise provide details for potential contact-tracing purposes.

App downloads have exceeded 840,000 since it was released in mid-November and more than 70,000 venues had signed up as of Tuesday. The app requires users’ permission to access a device’s camera, mobile network and storage.
