The ePrivacy Directive particularises and complements the GDPR for electronic communications. Where the Directive has a special rule, such as Article 5(3) terminal-equipment storage/access, Article 6 traffic data, Article 9 location data, or Article 13 direct marketing, that special rule must be applied rather than replaced by a generic GDPR lawful basis.
GDPR still matters. It governs personal-data processing that is not specifically covered by the ePrivacy special rule, including later analysis, enrichment, sharing, retention, profiling, security logging, data-subject rights, controller and processor roles, international transfers, and accountability. If Article 5(3) consent is invalid, the later GDPR processing that depends on that collection may also be defective.
Does GDPR Article 6 replace ePrivacy cookie consent?
No. If Article 5(3) requires consent for storing or accessing information in terminal equipment, a GDPR lawful basis cannot replace that ePrivacy access rule. GDPR lawful-basis analysis applies to later personal-data processing that is not itself governed by a more specific ePrivacy rule.
Who enforces ePrivacy issues?
Member States designate the competent authority or authorities for national ePrivacy rules. Data protection authorities enforce the GDPR, and may enforce national ePrivacy rules only where national law gives them that competence.
