A universal opt-in/opt-out client allows a user to connect to the APIs for various different sites which have the user's data. The universal client orchestrates opting out on any of the site lists provided by default, or sites which the user selects. The universal client enables the user to select total or partial opt-ins or opt-outs with granular control, on one or more web or decentralized sites, where the user may wish to allow some uses of data and access to data but would also like to restrict others. When a user is calibrating their privacy and data settings, a company or site may provide reasons and incentives for the user to allow access to certain data. This allows users to have simultaneous global control over their personal data while enabling the user to receive compensation for the use of their personal data, and allowing companies to have access to better data.
