GDPR Compliance

This guide provides comprehensive implementation instructions for General Data Protection Regulation (GDPR) compliance using Ring DAS. It covers consent management, user rights fulfillment, data protection measures, and audit procedures.

GDPR Overview

The General Data Protection Regulation (EU 2016/679) governs the processing of personal data for EU residents. Ring DAS processes personal data as both a data processor (on behalf of publishers/advertisers) and data controller (for its own analytics and optimization).

Key GDPR Principles

Ring DAS implementation addresses all six GDPR principles:

Lawfulness, fairness, transparency - Clear consent, transparent processing
Purpose limitation - Data used only for specified purposes
Data minimization - Collect only necessary data
Accuracy - Mechanisms to correct inaccurate data
Storage limitation - Configurable retention periods
Integrity and confidentiality - Security measures and encryption

Legal Bases for Processing

Ring DAS supports multiple legal bases under GDPR Article 6:

Legal Basis	Use Case	Implementation
Consent (6.1.a)	Personalized advertising, audience targeting	CMP integration, IAB TCF v2.2
Legitimate Interest (6.1.f)	Fraud detection, security	Documented LIA, easy opt-out
Contractual Necessity (6.1.b)	Service delivery to advertisers	DPA with clients
Legal Obligation (6.1.c)	Financial records, tax compliance	Automated retention

IAB Transparency & Consent Framework (TCF) v2.2

Ring DAS is fully compliant with IAB Europe's TCF v2.2 specification.
