Global Privacy Control (GPC) Signal Detection

Automatically detect and respect the Global Privacy Control signal sent by browsers, ensuring compliance with US state privacy laws and building trust with privacy-conscious visitors.

What it does:

• Detect GPC signal from visitor's browser (navigator.globalPrivacyControl)

• Automatically apply "Do Not Sell/Share" preferences when GPC is enabled

• Block advertising and targeting cookies for GPC-enabled visitors

• Integrate with Google Consent Mode v2 (GPC → ad_storage: denied)

• Log GPC detections for compliance documentation

Why it matters:

• Legal compliance – California (CCPA/CPRA), Colorado, Connecticut, and other US states legally require websites to honor GPC signals

• Future-proof – GPC is becoming a W3C standard with growing browser adoption (Firefox, Brave, DuckDuckGo, Safari extensions)

• User trust – Show privacy-conscious visitors that you respect their preferences

• Avoid penalties – Non-compliance with GPC requirements can result in regulatory fines

Features included:

• Real-time GPC signal detection

• Configurable rules (apply for US visitors only or globally)

• Dashboard analytics showing GPC signal statistics

• Optional banner text customization for GPC-detected visitors
