Powerful tracking, zero compromise.
Every feature is built with two goals: making tracking effortless and keeping your data exclusively yours.
AI Voice Logging
Hold to record. AI turns natural speech into structured logs, identifying foods, symptoms, and Bristol scale automatically.
Local-First Architecture
All logs stored on-device in IndexedDB via Dexie.js. Works fully offline, syncing only when you choose (if ever).
Privacy-Centric Analytics
Correlations like 'Food vs Symptoms' are computed client-side in the browser. Zero server-side processing of your health data.
Installable PWA
Install on iOS or Android directly from the browser. Runs like a native app with fast load times and touch optimization.

Zero tracking, by design.
GutVault isn't just a privacy policy; it's a technical guarantee. We built the app so we literally cannot see your data even if we wanted to.
- No analytics, no cookies, no behavioral tracking
- No cloud storage, your logs never leave your device
- Voice processing is ephemeral, no audio is retained
