Consent Requirement

This cookie is classified as necessary and typically does not require consent. It is essential for basic website functionality.

Consent Requirements by Regulation

GDPR & ePrivacy (EU)

Exempt from prior consent under the strictly necessary exemption (ePrivacy Directive Article 5(3)), provided cart_sig is genuinely required for the service the visitor requested. It must still be listed in your cookie policy.

UK GDPR & PECR

Exempt from consent under PECR Regulation 6(4) when strictly necessary. Disclosure in your cookie policy is still required.

CCPA/CPRA (California)

No opt-out is required for strictly necessary cookies, but cart_sig must be disclosed in your privacy policy.

Managing cart_sig with a Consent Banner

A consent management platform lists cart_sig in the banner's cookie table under the necessary category. Because it is strictly necessary, it stays active without an opt-in, but disclosing it keeps your cookie policy accurate. Kukie.io's scanner detects it automatically and keeps the disclosure up to date as your site changes.
