In a world where your morning coffee routine leaks more personal data than your grandparents shared in their entire lives, privacy isn’t optional—it’s survival.

Privacy by Design is a developer’s practical guide to building applications that protect user privacy from day one. Written for coders, engineers, and startup founders, this book cuts through the noise of compliance checklists and legal jargon to deliver hands-on techniques for creating privacy-first apps in the age of surveillance capitalism.

Inside, you’ll learn:
✅ Why surveillance is no longer a dystopian concept—it’s Tuesday morning.
✅ How to bake privacy into your system architecture using Ann Cavoukian’s 7 Principles.
✅ Threat modeling techniques simplified for builders (STRIDE, DREAD).
✅ Real-world cryptography you actually need: AES, Argon2, Zero-Knowledge Proofs.
✅ Secure coding patterns and architectural designs for privacy-first applications.
✅ Three complete projects:
• Secure Chat – An encrypted messaging app.
• Private Share – A peer-to-peer file sharing platform.
• Data Shredder – A file annihilation toolkit for truly deleting sensitive data.
✅ Usability and compliance strategies (GDPR, HIPAA, PCI DSS) for privacy-aware UX.

With detailed code examples in Python and JavaScript, practical checklists, and a developer-centric approach, Privacy by Design helps you move beyond theory to build systems that defend user privacy—even against nation-state adversaries.

If you’ve ever thought “I’m just building a to-do app; privacy doesn’t apply to me,” this book will change your perspective forever.

The future of digital privacy isn’t decided by governments or corporations—it’s built by developers like you. This book shows you how.
