A consent receipt management system is configured to: (1) automatically cause a prior, validly received consent to expire (e.g., in response to a triggering event); and (2) in response to causing the previously received consent to expire, automatically trigger a recapture of consent. In particular embodiments, the system may, for example, be configured to cause a prior, validly received consent to expire in response to one or more triggering events such as: (1) a passage of a particular amount of time since the system received the valid consent (e.g., a particular number of days, weeks, months, etc.); (2) one or more changes to a purpose of the data collection for which consent was received; (3) one or more changes to a privacy policy associated with the consent; (4) one or more changes to one or more rules that govern the collection or demonstration of validly received consent; etc.
