GDPR & ePrivacy (EU)

Prior consent is required before setting _clck. Analytics cookies are not covered by the strictly necessary exemption; only a few regulators (for example France's CNIL) allow a narrow exemption for first-party audience measurement under strict conditions.

UK GDPR & PECR

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

CCPA/CPRA (California)

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

Managing _clck with a Consent Banner

A consent management platform keeps _clck 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.
