iOS 27.3 Safari adds Global Privacy Control, but sites can ignore it

The iOS 27.3 beta quietly adds a Safari switch that tells every site not to sell or share your data. It won't kill cookie banners in Europe, though.

Apple has slipped a privacy switch into the iOS 27.3 beta, and it didn't mention it in the release notes. Safari now has a Global Privacy Control option that asks every site you visit not to sell or share your data.

Nick Heer spotted it on his blog Pixel Envy, and 9to5Mac followed on November 11. You'll find it under Settings > Apps > Safari > Advanced, as "Use Global Privacy Control". It is off by default, and it sits far from Safari's other anti-tracking protections, which Heer isn't thrilled about. Apple warns that some sites may work badly or not at all with it on. The help page linked from the setting currently leads to a page not found. It should go live with the final release, which also brings vertical tabs and an adaptive dark mode to Safari.

What is Global Privacy Control?

GPC is a signal the browser sends to each site you load. It was designed in 2020 by researchers including Sebastian Zimmeck of Wesleyan University and Ashkan Soltani, a former FTC chief technologist, with backing from the EFF. Firefox, Brave and DuckDuckGo's browser already support it. Chrome and Edge don't.

It may remind you of Do Not Track, the 2010s signal many people switched on and almost no site respected. GPC has legal weight in five US states. In California, the CCPA treats it as a valid refusal of data sales.

Will it remove cookie banners in Europe?

No. No European rule currently forces sites to honour the signal, so a site that receives it will still show its GDPR banner, which is what counts in the EU.

Europe came close to going further. The European Commission's Digital Omnibus, presented on November 19, 2025, proposed an automated browser-level signal every site would have to respect. On June 18, 2026, the EU Council dropped the measure, backed by France, Germany and Poland. Ad-funded media feared for their revenue.

Apple's version also only lets you refuse. Heer imagines a future where you state your preference once and never see a banner again, but a setting that can only say no is a long way from that.
