Detailed explanation

Core concepts: Data controller (decides which data is processed for what), data processor (processes on behalf of controller), data subject (the individual). Based on Law 6698 + Authority decisions.

5 obligations: (1) Privacy notice (KVKK Article 10), (2) Explicit consent (Article 5), (3) VERBIS registration (50+ employees or $1M+ revenue), (4) Retention policy, (5) Security measures (HTTPS, encryption, RBAC, audit log).

Difference vs GDPR: Similar in structure but KVKK is Turkey-specific. Cross-border EU transfer needs extra mechanisms + Turkey-specific explicit consent format + lower fines than EU (KVKK $67K, GDPR 4% global revenue).

For websites: privacy notice + cookie banner (3+ categories) + form-based explicit consent + 12-month log retention + KVKK form (data subject request). New 2026: extra notice + PII redaction for sites using AI/LLM.
