Data masking is a data security technique in which a dataset is copied but with sensitive data obfuscated.

Example:  For Mobile number 7000000012 it will be masked as 7000000XXX.

The main admin can decide which data on the panel should be visible on the UI for the sub-admin users

Areas where masking is provided:

Contacts >> All Contacts

Contacts >> List >> List of contacts

Contacts >> Segment >> List of contacts in segment

Contacts >> [Individual Contact] >> Details >> Unified view of contact

Email >> Campaign performance

SMS >> Campaign performance

All detailed report download

Activity dashboard UI & download reports

Basically, masking Email and Mobile data of end-user.
