ChainVault Ledger is a standalone, offline application built for law enforcement to manage physical evidence with full chain-of-custody integrity. It records every transfer, storage, and handling event through immutable logs, assigning unique identifiers, precise timestamps, and digital signatures. Each piece of evidence receives a QR label for quick access and verification, while detailed PDF reports can be generated for audits or court submissions. The system ensures data privacy by storing all information locally in an encrypted IndexedDB, eliminating reliance on external servers or cloud services.
The application runs directly in any modern web browser without installation, supporting desktop, tablet, and mobile devices. It operates in read-only mode during previews, preventing unauthorized edits. Designed for secure, real-time use in field operations, ChainVault Ledger maintains a complete and tamper-proof audit trail. Its lightweight single-file structure simplifies deployment and reduces technical barriers, making it ideal for agencies seeking reliable, low-overhead evidence tracking.
