A privacy management system (PMS) is disclosed for a Chief Privacy Officer (CPO) or other user to use in monitoring and/or controlling in realtime the flow of data (e.g., outflow) about the user and his/her online experience. The PMS may provide a dashboard displaying a whitelist and/or blacklist indicating what destinations/sources are blocked or allowed. The PMS includes browser-client scripting code and may also include a PMS-certified verification icon for display on webpages being monitored/controlled in realtime by the PMS.
