Privacy by Design

Overview

Integrate privacy protections into software architecture from the beginning, not as an afterthought. This skill applies Privacy by Design principles (GDPR Article 25, Cavoukian's framework) when designing databases, APIs, and user flows. Protects real users' data and builds trust.

When to Use This Skill

• Use when building apps that collect personal data (names, emails, locations, preferences)
• Use when designing database schemas, APIs, or authentication flows
• Use when the user mentions forms, user accounts, analytics, or third-party integrations
• Use when deploying to production—verify privacy controls before launch

Legal Frameworks

GDPR (EU) — Primary reference. Article 25 mandates "data protection by design and by default." Applies to EU users and often adopted globally.

CCPA (California) — Right to know, delete, opt-out of sale. Similar principles: minimize, disclose, allow control.
