CPRA: California's privacy framework

The California Privacy Rights Act (CPRA) amended and expanded the CCPA, adding a right to limit sensitive personal information, a 'sharing' opt-out for cross-context behavioural advertising, data-minimisation and retention duties, and a dedicated regulator, the California Privacy Protection Agency. This page explains, educationally, what the CPRA changed for analytics.

What the CPRA added

Building on the CCPA, the CPRA introduced a new category of 'sensitive personal information' with a right to limit its use, a 'sharing' opt-out aimed specifically at cross-context behavioural advertising, express data-minimisation and storage-limitation principles, a right to correct inaccurate data, and the California Privacy Protection Agency (CPPA) to enforce and write regulations.

Effect on analytics and ads

For measurement, the most consequential change is the 'sharing' concept: tags that pass identifiers to third parties for cross-context behavioural advertising can require a Do Not Sell or Share path and must honour opt-out preference signals like Global Privacy Control. Retention and minimisation duties also push toward collecting and keeping only what the disclosed purpose needs — which aligns with first-party, purpose-limited measurement.

How it appears in analytics and logs

Ad or analytics tags disclosing identifiers for cross-context advertising fall under CPRA 'sharing', so a missing opt-out or honoured GPC signal is a compliance gap.

Diagnostic use case

Map your California data flows against CPRA's sharing opt-out, sensitive-data limits, and retention duties to identify analytics or ad tags that need controls.

What WebmasterID can help detect

WebmasterID's first-party model with no cross-context advertising avoids the 'sharing' activity CPRA's opt-out targets.
