Documentless Biometric Finance Desktop App -- 4

I need a Windows desktop application that lets users grow their money while authenticating solely with Face ID or Touch ID—no passport scans, utility bills, or any other paperwork. At launch, a first-time user should enrol a biometric through Windows Hello; every subsequent sign-in must rely only on that biometric match.

Core flow
• Biometric enrolment → secure profile creation
• Deposit interface (bank API or manual ledger)
• Real-time balance growth calculator with configurable rate
• Withdrawal request and transaction log
• Admin dashboard for rate edits, user oversight, and audit trails

Technical expectations
The build can be in C#/.NET (WPF, WinUI) or Electron with Node.js if you prefer—so long as it hooks cleanly into Windows Hello for facial recognition and fingerprint. All sensitive data must be AES-256 encrypted at rest; API calls over TLS 1.2+. Please package the final app in an installer that runs on Windows 10 and 11 without extra dependencies.

Acceptance criteria
1. User can install, enrol biometrics, and access their account without ever supplying documents.
2. Deposits immediately reflect in the dashboard; the growth algorithm updates balances automatically at the set interval.
3. Any failed biometric attempt is logged and locked after 5 tries.
4. Source code, build instructions, and a signed installer delivered within the agreed timeframe—ASAP.
