The Global Privacy Control (GPC) Inspector, developed by Protegis.io, is a free Chrome extension that allows users to opt-out of the sale of their personal data using the GPC signal. With the increasing importance of data privacy laws such as the California Consumer Privacy Act (CCPA), the GPC signal has become a crucial tool for website visitors to protect their personal information.

This extension not only enables users to set the GPC signal, but also provides a way to evaluate website behavior based on this setting. Users can determine which websites honor their opt-out setting and understand whether their personal data is being shared with third parties.

For developers and IT teams, the Global Privacy Control Inspector offers diagnostic capabilities to understand and debug how webpages respond to the GPC signal. It allows users to validate whether the GPC signal was set and if the website response is consistent with the GPC specification. Additionally, it helps diagnose website behavior by checking if the GPC signal was read by the page. Users can also debug whether personal data is being shared by examining the information provided to third parties through beacons and cookies.

Overall, the Global Privacy Control (GPC) Inspector is a valuable tool for individuals who want to exercise their right to opt-out of the sale of personal information and for developers and IT teams to ensure compliance with data privacy regulations.
