GDPR

Definition

GDPR (General Data Protection Regulation) is the EU's data protection regulation (2018). It covers any company worldwide processing EU citizens' data. Fines reach 4% of global revenue or €20M — whichever is higher. Notice + consent + DPA + DPO appointment + 72-hour breach notification are mandatory.

Detailed explanation

7 core principles: lawfulness, purpose limitation, data minimization, accuracy, retention, integrity + confidentiality, accountability. Each principle requires separate documentation.

Data subject rights (8): information, access, rectification, erasure ('right to be forgotten'), restriction, portability, objection, opt-out from automated decisions. 30-day response window for each.

Software compliance: consent banner (granular categories), data export (machine-readable), delete-on-request, audit log, encryption at rest + in transit, DPO (Data Protection Officer) appointment (250+ employees).

Mandatory for companies with EU customers — if you sell from Turkey into the EU, GDPR compliance is required, KVKK alone is not enough. Standard Contractual Clauses (SCC) + EU representative may be required.
