This GPC Chrome Extension enables the Global Privacy Control opt-out signal and evaluates how websites respond to the setting
This Global Privacy Control Chrome Extension enables the GPC setting and evaluates whether whether websites honor the opt-out setting by providing transparency into the personal data shared with third parties.
The right for website visitors to opt-out of the sale of personal information is a hallmark of data privacy laws such as the California Consumer Privacy Act (CCPA). Regulators are accelerating enforcement against companies that do not honor the Global Privacy Control (GPC) signal as a valid opt-out. "Under law, [GPC] must be honored by covered businesses as a valid consumer request to stop the sale of personal information." https://oag.ca.gov/privacy/ccpa"
For developers and IT teams, this extension helps understand and debug how webpages respond to the GPC signal. Diagnostic capabilities include:
- Validate the GPC signal was set and the website response is consistent with the GPC specification
- Diagnose website behavior including whether the GPC signal was read by the page
- Debug whether personal data is shared by examining information provided to third parties using beacons and cookies.

- Works perfectly, from what I've seen the devs have great response time to bugs and other issues. Even better that I haven't had to write one, so if I could give more than 5 stars I would.
- Rome Williams
- The idea is a good one in theory, but in practice the recognition mechanism is overly specific. If the confirmation code doesn't come back an exact match, the result will be an incorrect 'fail' (false negative). There are a growing number of websites that have GPC enablement: United, Sixt, Honda, Toyota, Subaru, Fiat, and many others, but this extension is not providing an affirmative response to those compliant sites. The New York Times site gets a green light, but that's the only one I found in my sample size. So if you are a consumer or state privacy regulator using this to try and determine if a privacy election is being honored by a company, be forewarned that it doesn't necessarily give you an accurate answer.

- Previously knocked a few stars off because of a small but important bug with the signal. *However*, the devs not only fixed it almost immediately, they also tracked me down on another account because my email was deactivated, to let me know. Honestly shocking how responsive they are. Most of my paid products don't have that level of service. So 5 stars for the extension, and would recommend their business as well if anyone needs it.

- The extension works as described! The developer worked with me to fix an issue where the list of scripts did not appear. Now I can copy the list to share in reports. Thank you!

- Hi Delson, The extension is really good and works fine There is a minor issue though, whenever the enable GPC option is checked and unchecked, the details are not visible right away even if the page is reloaded. The extension needs to be reopened again for the details to show and it seems to be checking GPC compliance on chrome:// or file:// type urls where it is supposed to do nothing. Also I am confused with the way the headers are set when you are using declarativeNetRequest to set the GPC header, the extension is applying it to all resource types like images,fonts,stylesheets as well is that intended and really necessary? Thanks. Rutuj Runwal, Creator - RR Adblocker

- It is quite good but it does not actually add Sec-Gpc header to requests! So it wont work on websited that use backend to detect GPC. Please fix it. UPD: seems to be fixed now! The devs are great!

- hi Delson, I saw your reply. But it's still like what Vict said, `Sec-Gpc` is indeed not set in the header. My device is a Mac with version 13.3.1 and Chrome with version 112. I can reproduce the same problem on another Windows device, and another colleague of mine has also reported the same issue. Maybe you should verify this issue on a clean machine? https://imgur.com/a/eccVDl7
