I was looking for a way to move Privacy Center policies between Salesforce environments so I started looking at custom objects but nothing there really so it couldn’t be data. Next I looked at the installed packages in the org and there were 3 pieces of custom metadata listed. Maybe policies are custom metadata?
Next I created a SalesforceDX project and did a sfdx force:source:retrieve
from the Privacy Center org and boy was there a lot of custom metadata records. So my best guess is that the policies are actually custom metadata meaning it could be deployed from org to org with the metadata API. Yay!
The records are split across 3 custom metadata types:
privacycenter_Data_Object
privacycenter_Data_Field
privacycenter_Data_Policy
