Offline-first as an architectural decision for a mobile app

The real-world AuraHarmony project illustrates the architectural consequences of a consistent offline-first strategy: core functionality remains on the device, the main application flow does not depend on a cloud service, and no tracking infrastructure is required. Privacy is treated as an architectural decision rather than an afterthought.

Architecture principles

Offline first: Local processing
Core function: No cloud dependency
Privacy: No tracking
Platforms: iOS / Android
