Development Philosophy

"Security is not about secrecy — it's about trust, design, and verification. Building tools that empower users with privacy and control over their digital lives."

$ cat philosophy.txt
# Trust through transparency
# Security by design, not by default
# Privacy as a fundamental right
# Code that empowers, not enslaves
