Number of Users Requesting to Deregister from TraceTogether Programme
Prime Minister's OfficeSpeakers
Summary
This question concerns the number of individuals requesting deregistration from the TraceTogether programme and the procedures for notifying them of data deletion. Ms He Ting Ru inquired about these statistics, to which Minister Vivian Balakrishnan responded that 1,155 users had deregistered as of April 2021. Minister Vivian Balakrishnan explained that app users receive SMS notifications and token users receive on-the-spot confirmation, with registration data deleted within five working days. He noted that while local data is removed after 25 days, uploaded records are retained for public health necessity until the pandemic is over. Under the COVID-19 (Temporary Measures) Act, all personally identifiable data must be deleted once the Minister specifies a date following the pandemic's conclusion.
Transcript
4 Ms He Ting Ru asked the Prime Minister (a) how many users have requested to be deregistered from the TraceTogether programme; and (b) whether the users making the requests will be notified that their data has been deleted following their request.
Dr Vivian Balakrishnan (for the Prime Minister): As of the 30 April 2021, there were 4,923,054 individuals on board the TraceTogether (TT) programme, or approximately 92% of the population above the age of six years. As of the same date, only 1,155 users (or 0.021% of the population above the age of six years) had requested deregistration from the TT programme.
TT App users who apply to deregister will be sent a SMS confirming that their request has been received. For users returning the TT Token, the officer receiving the token at the Community Centre will provide confirmation of the deregistration on the spot.
All TT registration data, including NRIC or contact number, is deleted from the TT server within three to five working days. Consequently, any data previously exchanged with other TT devices cannot be decrypted any longer. When the user uninstalls the app, all previously collected data will also be permanently deleted from the smartphone. In any case, all data is deleted from TT devices automatically after 25 days.
If a user had previously been identified as a close contact and uploaded his or her data to the Government’s server for contact tracing purposes, these records are retained. This is essential for public health reasons. Notwithstanding this, subsection 82(9) of the COVID-19 (Temporary Measures) Act allows the Minister to specify a date, once the pandemic is over, after which all personally identifiable contact tracing data must be deleted as soon as reasonably practicable.
