What if I want to capture PII in any one of the variables? What is the process?
If we are not supposed to do so, how should we take an approval for the same and whom should we contact?
While Adobe strongly recommends that you do not pass any PII information with Analytics hits, there is no filter which will remove the PII data while processing.
In case of any doubt, please contact your company's Legal team to check if it is okay to capture and pass the specific data to Adobe servers.
Agreed with Kaushalendra here - Adobe does not recommend collecting PII, and your customers/users are going to be the biggest concern when it comes to any privacy violations.
