Overview of consent frameworks

CookieHub supports multiple consent frameworks to help you comply with different privacy regulations and platform requirements. A consent framework defines how user choices are collected, stored, and communicated to vendors.

A consent framework provides a structured way to:

  • Collect and manage user consent or opt-out preferences
  • Communicate these preferences to third-party vendors, ad tech platforms, or analytics tools
  • Ensure compliance with regional laws and industry standards

Frameworks standardize how consent data is shared across the ecosystem using machine-readable strings or signals.

Frameworks supported by CookieHub

CookieHub supports three frameworks:

  • CookieHub Choices

    Default framework using category-based consent. Suitable for most global privacy laws when no external signaling is required.

  • IAB Transparency and Consent Framework (TCF) 2.3

    Used for GDPR/ePrivacy compliance in the EU and UK. Required by many ad platforms (e.g., Google Ads, Meta) for personalized advertising.

  • IAB Global Privacy Platform (GPP)

    Used for US privacy laws. Supports opt-out signals for states such as California (CPRA) and Colorado (CPA).

Integrations with external systems

In addition to these frameworks, CookieHub integrates with industry tools that require specific consent signals:

  • Google Consent Mode v2

    Communicates consent status to Google tags for measurement and advertising.

  • Google Additional Consent Mode

    Handles vendors not registered with the IAB TCF.

  • Microsoft UET Consent Mode

    Sends consent signals to Microsoft advertising tags.

  • IAB US Privacy (legacy)

    Maintains backward compatibility with older US Privacy strings.

Choosing the right framework

  • Use CookieHub Choices if you do not need to send IAB strings and prefer category-based consent.
  • Use IAB TCF 2.3 if you serve personalized ads in the EU or UK through vendors that require TCF signals.
  • Use IAB GPP if you need to comply with US state privacy laws and signal opt-out preferences to vendors.
