Consent Record Audit
Issues detectedConsent record stored after interaction
GDPR Art. 7(1)No consent record written — cannot prove consent was given
No CMP consent cookie or localStorage entry was found after the consent interaction. GDPR requires controllers to demonstrate consent was given.
Consent withdrawal mechanism accessible
GDPR Art. 7(3)Cookie settings link / floating button found
Why this matters
Under GDPR Article 7, controllers must be able to demonstrate that consent was given (Art. 7(1)) and ensure users can withdraw consent at any time, as easily as giving it (Art. 7(3)). Sites with no consent record or no withdrawal mechanism cannot legally rely on consent as a lawful basis.
