MyDeepStack: Bullion Tracker

Your precious metals portfolio, organized by purchase lot, always up to date, and private by design. MyDeepStack tracks what your stack is worth right now: gold, silver, and platinum at live spot prices, shown in your currency, with no account required and no portfolio data sent to us. Built for stackers who want a clear ledger, useful cost analytics, and strong privacy without maintaining a spreadsheet. Track coins, bars, rounds, and constitutional silver by metal, item, weight, quantity, and purchase lot. Repeated purchases roll up into one clean holding summary while every individual lot keeps its own date, cost method, source, and notes. See current value, cost basis, P&L, return percentage, purchase economics, gold/silver ratio, and historical charts at a glance. Private by design: - Your stack is stored in an encrypted file on your device — never uploaded, never collected - Optional App Lock: require Face ID, Touch ID, or your passcode to open the app - Portfolio values are hidden from the app switcher when App Lock is on - Your encrypted stack rides inside your phone's own backups so a new phone gets it back — or flip on Local Storage Only to exclude it from backups and pin the key to that device - Zero data collection. No account. No servers.
