Product Philosophy
Privacy-First
Privacy is a base assumption, not a feature.
Offline-First
Apps must work, even when the connection doesn't.
Modular
Small, isolated apps with a shared codebase — testable, flexible, different flavors.
Simple First
Start simple to avoid AI overengineering — complexity grows with knowledge.
