🛡️ Valora — Sensitive Data Guard

Valora is a powerful Data Loss Prevention (DLP) solution designed to protect sensitive information from leaking into third-party AI platforms like ChatGPT, Google Gemini, and Claude.

Built for Everyone: Whether you are an enterprise seeking to enforce corporate data policies or an individual user looking to protect your personal privacy, Valora operates through a real-time Chrome extension that actively monitors user input. It identifies and auto-masks generic Personally Identifiable Information (PII) alongside custom keywords before the data ever leaves the browser.

🚀 Key Features

  • Real-time AI Platform Monitoring: Silently runs on AI interfaces (ChatGPT, Claude, Gemini) scanning for violations on the fly.
  • Dual Modes of Operation:
    • Enterprise Mode: Multi-tenant architecture for organizations. Configure custom domains, keywords, and rule bypasses via an Admin Dashboard. Features automated auto-masking for company secrets.
    • Individual Mode: Perfect for personal safety. Protects everyday users from accidentally pasting credit cards, SSNs, API keys, or personal emails into AI models. Includes a generous free tier (up to 50 scans).
  • Smart Auto-Masking: Automatically replaces custom company keywords with inline asterisks (***), ensuring context is retained while protecting sensitive variables.
  • General PII Protection: Built-in detection for standard sensitive data (Credit Cards, SSNs, API Keys, Emails, Phone Numbers).
  • Admin Dashboard Analytics (Enterprise): A modern, dark-mode React Dashboard featuring rich charts, timeline views, Top Offender lists, and platform usage metrics.
  • Active User Heartbeats: Tracks active employee usage daily. Includes an automated chron job that emails administrators and users if they disable or abandon the protection extension.

📂 Project Structure

This repository contains the complete Valora ecosystem, divided into three main applications:

  1. valora-admin/ (Frontend Dashboard)

    • A responsive, beautifully crafted Vite + React frontend dashboard.
    • Allows organization admins to track violations, manage rules, invite employees, and view rich data visualizations (Recharts).

  2. valora-backend/ (Node.js API)

    • An Express & MongoDB backend handling authentication, rule delivery, and logging.
    • Multi-tenancy enabled via organizational scoping (orgId).
    • Includes automated cron jobs (inactivityChecker.js) using Nodemailer to alert inactive employees.

  3. valora-extension-v2/ (Chrome Extension)

    • A Manifest V3 Chrome Extension.
    • Communicates seamlessly with the backend via background.js and uses a localized algorithm in content.js/detector.js to execute real-time regex matching and UI interceptions (blocking the send button, showing warning modals).

🛠️ Tech Stack

  • Frontend: React, Vite, CSS Modules, Recharts
  • Backend: Node.js, Express, MongoDB, Mongoose, JWT Authentication
  • Extension: Vanilla JavaScript, Chrome Extension API (Manifest V3)
  • Utilities: Nodemailer (SMTP alerting), Dotenv

🚦 Getting Started

Prerequisites

  • Node.js (v18+ recommended)
  • MongoDB Database (Local or MongoDB Atlas)

1. Setup the Backend

cd valora-backend
npm install

Create a .env file in the valora-backend directory:

MONGO_URI=mongodb://127.0.0.1:27017/valoraPORT=5000JWT_SECRET=your_jwt_secretSMTP_HOST=smtp.gmail.comSMTP_PORT=587SMTP_USER=your_email@gmail.comSMTP_PASS=your_app_passwordSMTP_FROM=your_email@gmail.comINACTIVITY_DAYS=3

Run the server:

npm run dev

2. Setup the Admin Dashboard

cd valora-admin
npm install

Run the development server:

npm run dev

3. Load the Chrome Extension

  1. Open Google Chrome and navigate to chrome://extensions/
  2. Enable "Developer mode" in the top right corner.
  3. Click "Load unpacked" and select the valora-extension-v2 folder.
  4. Click the Valora puzzle piece icon in your browser to sign in to your Employee or Admin account.

🔒 Security & Privacy First

Valora's detection runs entirely inside the user's browser via the extension's content scripts. Keystrokes are never logged to the server. The backend only receives metadata when a violation policy is breached (e.g., the platform used and the type of data matched), ensuring maximum user privacy.

Developed for robust data compliance and enterprise AI safety.

🛡️ Valora — Sensitive Data Guard
Valora is a powerful Data Loss Prevention (DLP) solution designed to protect sensitive information from leaking into third-party AI platforms like ChatGPT, Google Gemini, and Claude.
Built for Everyone: Whether you are an enterprise seeking to enforce corporate data policies or an individual user looking to protect your personal privacy, Valora operates through a real-time Chrome extension that actively monitors user input. It identifies and auto-masks generic Personally Identifiable Information (PII) alongside custom keywords before the data ever leaves the browser.
🚀 Key Features
  • Real-time AI Platform Monitoring: Silently runs on AI interfaces (ChatGPT, Claude, Gemini) scanning for violations on the fly.
  • Dual Modes of Operation:

    • Enterprise Mode: Multi-tenant architecture for organizations. Configure custom domains, keywords, and rule bypasses via an Admin Dashboard. Features automated auto-masking for company secrets.
    • Individual Mode: Perfect for personal safety. Protects everyday users from accidentally pasting credit cards, SSNs, API keys, or personal emails into AI models. Includes a generous free tier (up to 50 scans).
  • Smart Auto-Masking: Automatically replaces custom company keywords with inline asterisks (***), ensuring context is retained while protecting sensitive variables.
  • General PII Protection: Built-in detection for standard sensitive data (Credit Cards, SSNs, API Keys, Emails, Phone Numbers).
  • Admin Dashboard Analytics (Enterprise): A modern, dark-mode React Dashboard featuring rich charts, timeline views, Top Offender lists, and platform usage metrics.
  • Active User Heartbeats: Tracks active employee usage daily. Includes an automated chron job that emails administrators and users if they disable or abandon the protection extension.
📂 Project Structure
This repository contains the complete Valora ecosystem, divided into three main applications:
  1. valora-admin/ (Frontend Dashboard)
    • A responsive, beautifully crafted Vite + React frontend dashboard.
    • Allows organization admins to track violations, manage rules, invite employees, and view rich data visualizations (Recharts).
  2. valora-backend/ (Node.js API)
    • An Express & MongoDB backend handling authentication, rule delivery, and logging.
    • Multi-tenancy enabled via organizational scoping (orgId).
    • Includes automated cron jobs (inactivityChecker.js) using Nodemailer to alert inactive employees.
  3. valora-extension-v2/ (Chrome Extension)
    • A Manifest V3 Chrome Extension.
    • Communicates seamlessly with the backend via background.js and uses a localized algorithm in content.js/detector.js to execute real-time regex matching and UI interceptions (blocking the send button, showing warning modals).
🛠️ Tech Stack
  • Frontend: React, Vite, CSS Modules, Recharts
  • Backend: Node.js, Express, MongoDB, Mongoose, JWT Authentication
  • Extension: Vanilla JavaScript, Chrome Extension API (Manifest V3)
  • Utilities: Nodemailer (SMTP alerting), Dotenv
🚦 Getting Started
Prerequisites
  • Node.js (v18+ recommended)
  • MongoDB Database (Local or MongoDB Atlas)
1. Setup the Backend
cd valora-backend
npm install
Create a .env file in the valora-backend directory:
MONGO_URI=mongodb://127.0.0.1:27017/valoraPORT=5000JWT_SECRET=your_jwt_secretSMTP_HOST=smtp.gmail.comSMTP_PORT=587SMTP_USER=your_email@gmail.comSMTP_PASS=your_app_passwordSMTP_FROM=your_email@gmail.comINACTIVITY_DAYS=3
Run the server:
npm run dev
2. Setup the Admin Dashboard
cd valora-admin
npm install
Run the development server:
npm run dev
3. Load the Chrome Extension
  1. Open Google Chrome and navigate to chrome://extensions/
  2. Enable "Developer mode" in the top right corner.
  3. Click "Load unpacked" and select the valora-extension-v2 folder.
  4. Click the Valora puzzle piece icon in your browser to sign in to your Employee or Admin account.
🔒 Security & Privacy First
Valora's detection runs entirely inside the user's browser via the extension's content scripts. Keystrokes are never logged to the server. The backend only receives metadata when a violation policy is breached (e.g., the platform used and the type of data matched), ensuring maximum user privacy.
Developed for robust data compliance and enterprise AI safety.
