Consent Requirements by Regulation

GDPR & ePrivacy (EU)

Explicit prior consent is required before setting GN_PREF. Advertising and tracking cookies are never covered by the strictly necessary exemption.

UK GDPR & PECR

Explicit consent is required before setting GN_PREF.

CCPA/CPRA (California)

Setting GN_PREF for cross-context behavioural advertising is treated as sharing personal information: provide a "Do Not Sell or Share" opt-out and honour the Global Privacy Control signal.

Managing GN_PREF with a Consent Banner

A consent management platform keeps GN_PREF blocked until the visitor opts in to the marketing category. Kukie.io's scanner detects it automatically, categorises it, and the banner's auto-blocking holds back the script that sets it until consent is given - visitors who decline never receive it.
