Baby Vault – Track your newborn’s data locally without backend or cloud storage

Summary: Baby Vault is a local-first Progressive Web App that tracks newborn feeds, sleep, and growth without uploading data to any server. It stores all information in the browser’s IndexedDB, ensuring data privacy and offline functionality. The app includes a medical-grade "Doctor's Report" summarizing key metrics for pediatricians and supports JSON export/import for data portability.

What it does

Baby Vault records newborn care data entirely on the device, working offline and in Wi-Fi dead zones. It provides a single-page report summarizing feeds, output, and growth over the past week for medical use.

Who it's for

It is designed for new parents who want to track their baby’s health data privately without relying on cloud services or accounts.

Why it matters

It solves privacy concerns by keeping all data local and accessible without internet, while offering a clear, exportable summary for pediatricians.
