Why I built Sanctuary: A local-first, zero-tracking reflection app

Most journaling and mental wellness apps require syncing sensitive personal thoughts to cloud servers where they risk being mined or exposed. I wanted a space where user data never leaves the browser. So I built Sanctuary - a lightweight, local-first reflection vault.

Technical Highlights

• 100% Local-First: All entries and app states stay strictly inside browser local storage. Zero tracking scripts or analytics.
• Resonance Diagnostics: Dynamic, client-side SVG visualizations mapping baseline mood trends over time.
• Therapy PDF Export: Uses native CSS print styling (@media print) to generate clean offline summary reports for check-ins without sharing app access.
• Zero Overhead: Blazing fast load times with no database or cloud sync latency.

I'd love feedback from the dev community on the local storage architecture, baseline algorithms, or visual UI!
