Secure Receipt Scraper & Dashboard

Nex Receipt Vault is a production-ready, Manifest V3 Chrome extension designed for privacy-first purchase tracking. It eliminates the need for intrusive bank connections by capturing order data directly from browser confirmation pages. This skill provides the complete, working source code—originally a shipped product—built on a vanilla JS, HTML, and CSS architecture.

What it does

The extension monitors active tabs for order-confirmation patterns. Once detected, its specialized extraction engine parses merchant details, itemized lists, totals, and dates. All data is stored locally on the user's device. The included popup provides a comprehensive spending dashboard and history view. Key features include:

• Multi-Platform Detectors: Pre-built support for Amazon, Shopify, WooCommerce, and more.
• Intelligent Classification: Distinguishes between standard pages and valid receipts.
• Zero-Build Workflow: Edit and reload instantly without npm or bundlers.
• Privacy-Centric: No accounts, no servers, and no third-party data access.

Why use this skill?

Building reliable web scrapers that survive DOM changes is difficult. This skill saves days of development by providing a field-tested architecture for DOM-based data extraction. It serves as both a functional tool and a masterclass in professional extension development, covering everything from background service workers to local storage persistence.
