Consent is required before setting _pk_ses. The ICO treats analytics cookies as non-essential.

CCPA/CPRA (California)

Disclose _pk_ses in your privacy policy and honour opt-out requests, including the Global Privacy Control signal, if the analytics data is shared or sold.

Managing _pk_ses with a Consent Banner

A consent management platform keeps _pk_ses blocked until the visitor opts in to the analytics 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.
