A consent system enables a consumer to save consent choices so that the publisher can retrieve the consumer consent choices when the consumer visits the publisher site, without requiring the consumer to make additional selections corresponding to consent choices. The consumer can save consent choices as a consent system first party cookie or in an account at the consent system. The consumer can save consent choices when visiting a publisher site or by accessing the consent system. The publisher can retrieve the consumer consent choices from the consent system first party cookie or from the account at the consent system. Multiple publishers can retrieve the consumer consent choices saved in an account with the consent system, enabling “cross-platform consent.”
