Custom fields are used to gather pieces of information about your partners via surveys. E.g., if you frequently collect partners' date of birth, you can create a birthday custom field using the date picker question type.
Create custom fields
From the left navigation bar, select [Menu] → Settings.
On the right, under Technical, select Custom Fields.
In the upper-right corner, select Create Custom Fields.
Complete the custom field information:
Name: Add a name to easily recognize the custom field when adding it to a survey.
Description: Add a custom field description to describe the data representing the custom field. This description will not be visible to the partner.
Privacy Level: Leave the privacy level as Private.
Display Type: Add the question type that best captures the data for which you are looking.
