The TraceTogether and SafeEntry systems are now no longer operating and all COVID-related personal data collected from the two platforms has been deleted, confirmed the Smart Nation Group, which is a government agency that sits under the Prime Minister's Office and is managed by the Ministry of Communications and Information.
User registration data, which was kept to enable quick rollout and registration for both systems, should a new variant emerge, has also been erased.
The only data retained was collected via the TraceTogether system and used in relation to a May 2020 murder case. This information will be held indefinitely by the Singapore Police Force to facilitate potential legal applications, should the conviction or sentence be challenged years after the case has concluded. This situation may require the police to disclose the data.
The backend infrastructures for the TraceTogether and SafeEntry systems have also been dismantled and their frontend websites shut down. In addition, the mobile apps for TraceTogether and SafeEntry Business have been removed from official app stores.
Introduced in March 2020, the TraceTogether app tapped Bluetooth signals to detect other participating mobile devices in close proximity, allowing the system to identify people who had been in close contact when needed. Data was captured, encrypted, and stored locally on the user's phone for 21 days and, when needed in contact-tracing processes, uploaded to the Health Ministry for review.
SafeEntry was used as a digital check-in system that gathered data to facilitate contact tracing of individuals, and the locations they visited, when they tested positive for COVID. QR codes were displayed at the entry and exit points of venues, such as supermarkets and shopping malls, which visitors had to scan and then input their name, national identification number, and mobile number.
