If you wish to ask websites to respect your privacy, you can use the “Tell websites not to sell or share my data” setting. This option is built on top of the Global Privacy Control (GPC). GPC is respected by increasing numbers of sites and enforced with legislation in some regions. To learn more about this, please read Global Privacy Control.
So those sites can look at that.
Ohh it’s forced by law in some countries, sounds better ngl.
