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 __cfduid 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 __cfduid must be disclosed in your privacy policy.
Managing __cfduid with a Consent Banner
A consent management platform lists __cfduid 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.
