The absence of a cookie banner on websites directly contravenes several international data privacy regulations, including the General Data Protection Regulation (GDPR) in the European Union, the Lei Geral de Proteção de Dados (LGPD) in Brazil, and the Personal Information Protection and Electronic Documents Act (PIPEDA) in Canada. These frameworks require explicit user consent before any personal data is collected via cookies.
Non-compliance with these laws results in clear legal and financial consequences. According to Article 7 of the GDPR, “the controller shall be able to demonstrate that the data subject has consented to processing of his or her personal data” (GDPR, Art. 7). Without a cookie banner, websites cannot prove such consent, exposing them to enforcement action. Similarly, the LGPD states that “the processing of personal data may only take place with the data subject’s free, informed and unambiguous consent”. PIPEDA also mandates “meaningful consent” for all collection and use of personal information (PIPEDA, Principle 3).
Key risks and observed consequences include:
Summary of findings from regulatory guidance and case law:
In conclusion, the lack of a cookie banner constitutes a clear violation of major privacy laws, with well-documented financial, reputational, and operational repercussions for organizations. Failure to comply is consistently met with regulatory enforcement and substantial penalties.
