Consent Requirement

This cookie is classified as functional. Under GDPR and similar regulations, explicit consent is recommended before setting this cookie.

Consent Requirements by Regulation

GDPR & ePrivacy (EU)

Consent is recommended before setting isFirstSession. Functional cookies are only exempt when strictly necessary for a feature the visitor explicitly requested, such as remembering a language choice they just made.

UK GDPR & PECR

Same position as the EU rules: obtain consent unless the cookie qualifies for the strictly necessary exemption.

CCPA/CPRA (California)

Disclose isFirstSession in your privacy policy. If the stored data is shared with third parties, opt-out requests, including the Global Privacy Control signal, must be honoured.

Managing isFirstSession with a Consent Banner

A consent management platform keeps isFirstSession blocked until the visitor opts in to the functional 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.
