For consumers, how does GPC work?
As a first step, privacy preferences can be set by the user in their browser if that browser supports the GPC standard.
The list of browsers that support GPC is continuously growing. As of this writing, this includes Firefox Nightly, Brave and DuckDuckGo. In addition to this, GPC has created a Chrome Plugin to support GPC on Chrome.
From their browser, the consumer sets their Global Privacy Control preference to
true, meaning they opt out of data sales or sharing. From the consumer’s perspective, that’s all there is to it - when the user browses future websites, their browser shares a signal that confirms the user has opted out of data sales or sharing. Your website must respect that signal and ensure the user's personal data is appropriately protected and not processed.
If you're unsure how to setup GPC support you can ask the Fides Slack Community, or get Privacy Engineering Intelligence from Ethyca now.
