No, not through the 2ndLine app!
The app does not trace your phone device. Further, we do not share the user's reserved 2ndLine numbers with anyone. In case approached by a user, we request a basic device configuration and reserved number only to provide solutions/support.
Also, we do not maintain any kind of directory service so there is no possibility for any person tracing to a user from the phone number.
Further, our infrastructure is highly secure with industry-standard measures.
