What It Does

Everything a stacker needs

Import your invoices, track your holdings, and watch your portfolio value in real time. No manual data entry required.

PDF Invoice Import

Drop in invoices from APMEX and SD Bullion. Metal type, weight, quantity, and price are parsed automatically. Accessories and non-metal items are filtered out.

Order History

Full order ledger with vendor, date, and line item detail. Filter by vendor, metal type, or year. Sort by any column. Expand any order to see exactly what was purchased.

Live Spot Prices

Fetches current spot prices for gold, silver, and copper via yfinance. Market value and gain or loss are calculated instantly for each metal and for the full vault.

Portfolio Summary

Per-metal totals showing ounces held, average cost per oz, current market value, and gain or loss. Vault-wide totals displayed at the top of the tab.

Analytics Charts

Three embedded charts: cumulative spending by metal over time, total oz held per metal, and annual spending breakdown by year. All rendered locally with matplotlib.

Product Holdings

Aggregated product breakdown showing every unique product, its total units, total oz, and average cost per unit. Filter by product name or metal type and sort any column.

Encrypted Backups

AES-128 encrypted backup and restore with password protection. Your holdings data is safe even if the backup file is stored offsite.

Dark and Light Themes

Full theme support built in. Switch between dark and light modes from the application menu at any time.

How It Works

Your stack stays private

QuietVault stores everything in a local SQLite database on your machine. The only network calls are spot price lookups, which send nothing but commodity ticker symbols.

Runs entirely on your machine
Python desktop application with PyQt6. No server, no Docker, no internet required for core features.
Encrypted backups
AES-128 encryption with PBKDF2 key derivation. Password protected, portable, and safe to store anywhere.
No accounts, no telemetry
No sign up, no login, no tracking. The app never phones home. Spot price lookups are read-only calls that send nothing personal.
