Deleting the app
When the App is deleted, all locally-stored data in the App will be deleted. A user will no longer be able to share the stored logs should they be contacted by a contact tracer. They need to re-install and set up the App again to participate in TraceTogether.
Switching Phones
If you've changed your phone and retained your original mobile number, no worries. You can download TraceTogether on your new phone and register with your mobile number. The TraceTogether data in your previous phone will not be ported over to your new phone. It will stay in your previous phone for 25 days, after which it'll be deleted.
Changing Phone Number
As of version 2.10.0, users are able to change their contact number via their profile page (More > Your Profile) on their TraceTogether App. Amend your number and perform the OTP verification, to reflect it successfully and enable timely contact tracing.
