A method may include receiving a consent-processing request at a consent management platform from a content-presentation device, and using an identifier string in the request to establish a secure interactive session configured for user selection of consent options associated with a particular consent package of the platform, where the package may include identifiers of consent features of a media distribution system that require user consent in order to be activated for the device. The platform may then receive, via the interactive session, user consent data including a respective consent choice for each of one or more consent options, where each respective consent choice indicates acceptance or rejection of consent to activating an associated consent feature identified with the particular consent package. The received respective consent choices may be stored in a database of the consent management platform. Corresponding data may be stored in a whitelist on the content-presentation device.
