A system and method for implementing a privacy policy in an application to be run are provided. Definitions are received for a set of fields. At least one of the fields is designated as sensitive by a default privacy policy. A user is provided with a consent editor whereby the user can consent to relaxing the default privacy policy for at least one of the sensitive fields. A consent privacy rule is generated based on the received consent. A mapping aspect is provided which identifies joins at which code of the application is to be augmented by calling a minimization service to apply the default privacy policy by generating a minimized value of data in each of the designated sensitive fields used by the application unless there is a generated consent privacy rule which authorizes relaxation of the default privacy policy for the user's data in a respective sensitive field.
