Note about sensitive data
Sensitive IDs - any field marked as a sensitive ID will be replaced with a random alphanumeric code. This code will be consistent within forms; that is if you are treating owner_id as a sensitive field and owner_id is the same in 10 form submissions, then it will be replaced with the same code in all of the form submissions.
Sensitive dates - dates are shifted by up to one month, randomly. However the length of the shift is consistent within a given form or case. So if in one form you ask both mother's date of birth and child's date of birth, both dates will be shifted by the same number.
