🛡️ Comprehensive Privacy Policy & Data Governance Charter

Strictly Compliant with the IT Act 2000, IT Rules 2021, DPDP Act 2023, GDPR, CCPA & Google AdSense Publisher Policies

✅ Effective Date: 01 October 2026 | Last Reviewed & Verified: October 2026

Executive Summary (सारांश): At BR DOT HUB (https://www.brdothub.in), your digital privacy is engineered directly into our technical architecture. Unlike traditional platforms that harvest and store student records on vulnerable central servers, BR DOT HUB utilizes a Decentralized Client-Side LocalStorage & IndexedDB Architecture. Your academic profile, mock test scores, bookmarks, and attempt histories remain stored directly inside your own device's browser. This Privacy Policy explains step-by-step how our platform works, how your data is handled across our CBT engine, AI Assistant, and Google AdSense advertising network, and how you can exercise 100% control over your digital footprint.

1.1 Binding Agreement & Explicit Consent: Welcome to BR DOT HUB. By accessing, browsing, registering a local profile, installing our Progressive Web Application (PWA), attempting Computer-Based Tests (CBT), or interacting with our "Ask AI" educational assistant, you explicitly acknowledge and consent to the data handling practices, cookie disclosures, and privacy safeguards detailed in this policy. If you do not agree with any provision of this Privacy Policy, please discontinue using the platform immediately and clear your browser's local storage and cache. (BR DOT HUB का उपयोग करके, आप इस गोपनीयता नीति में बताए गए सभी डेटा सुरक्षा नियमों, कुकीज़ और शर्तों से अपनी पूर्ण सहमति व्यक्त करते हैं।)

1.2 Applicability & Platform Scope: This Privacy Policy governs all sub-pages, study modules, Markdown study notes, JSON-powered mock test engines, daily rapid quizzes, leaderboard interfaces, and Progressive Web Application (PWA) installations associated with the domain https://www.brdothub.in, owned and operated by Niraj Kumar (Founder & Lead Developer), headquartered at Biharsharif, Nalanda, Bihar, India (PIN: 803101).

1.3 Statutory Compliance Framework: This document is drafted and enforced in strict accordance with applicable Indian and international data protection statutes:

The Digital Personal Data Protection Act, 2023 (DPDP Act, 2023): Ensuring lawful, transparent, and consent-based processing of digital personal data of individuals ("Data Principals") by BR DOT HUB ("Data Fiduciary").

The Information Technology Act, 2000 (Section 43A & Section 72A): Implementing Reasonable Security Practices and Procedures (RSPP) to prevent unauthorized access or disclosure of sensitive information.

The Information Technology (Intermediary Guidelines and Digital Media Ethics Code) Rules, 2021: Maintaining a transparent Grievance Redressal Mechanism with strict acknowledgment and resolution timelines.

International Privacy Standards (GDPR, UK GDPR, CCPA/CPRA & Google EU User Consent Policy): Providing global users with full transparency regarding third-party advertising cookies, cross-border API transmissions, and data erasure rights.

⚙️ Section 2: Step-by-Step Data Architecture — How BR DOT HUB Works (हमारा डेटा सिस्टम कैसे काम करता है)

To ensure complete transparency for students, parents, regulatory authorities, and advertising partners, below is the exact step-by-step technical workflow of how data is generated, stored, and processed when you use BR DOT HUB:

Step 1 — Voluntary Local Profile Initialization (प्रोफ़ाइल निर्माण): When you first visit BR DOT HUB, you may optionally enter basic academic identifiers—such as your Name, Age Group, Target Competitive Exam (e.g., Bihar Police, BSSC, RRB NTPC, Group D, ALP, SSC MTS/GD/CGL), and optional Avatar/Photo. This input is processed exclusively by client-side JavaScript inside your web browser.

Step 2 — Decentralized Client-Side Storage via LocalStorage & IndexedDB (ब्राउज़र में सुरक्षित स्टोरेज): Instead of transmitting your personal profile or test history to a centralized cloud database (such as SQL/NoSQL external servers), our application serializes your profile preferences, bookmarked questions, milestone badges, and CBT attempt scorecards into JSON objects and stores them directly inside your device's HTML5 window.localStorage and IndexedDB containers. (आपका नाम, टारगेट एग्जाम, बुकमार्क और टेस्ट स्कोर हमारे किसी पब्लिक क्लाउड सर्वर पर अपलोड नहीं होते, बल्कि आपके ही मोबाइल या कंप्यूटर के ब्राउज़र में सुरक्षित रहते हैं।)

Step 3 — Edge Content Delivery & Offline PWA Caching (तेज़ लोडिंग और ऑफलाइन कैशिंग): When you open a study note (.md) or a mock test (.json), our Service Worker and Edge Content Delivery Network (CDN) cache the static educational assets locally on your device. This ensures ultra-fast sub-second page transitions even on low-bandwidth 2G/3G rural networks without exposing your personal identity.

Step 4 — Genuine Human Leaderboard Sync (लीडरबोर्ड और रैंक गणना): When you submit a CBT Mock Test or Live Quiz and opt to participate in public peer rankings, only minimal, non-sensitive academic metrics (your chosen Display Name, Test ID, Marks Scored, Accuracy Percentage, and Time Taken) are processed to compute your percentile and rank among authentic human aspirants.

Step 5 — Instant One-Click Data Erasure (एक क्लिक में डेटा डिलीट करना): Because your core records reside on your device, clicking the "Delete Profile / Clear Data" button in your dashboard immediately executes localStorage.clear() and purges your IndexedDB containers, permanently wiping your profile, photo, and test history within milliseconds.

🗄️ Section 3: Categories of Information Collected & Purpose of Processing (संकलित डेटा के प्रकार और उद्देश्य)

Data Category	Specific Data Elements	Storage Location	Exact Purpose of Processing
1. Voluntary Academic Profile Data	Candidate Name, Age, Target Exam Category, Optional Profile Picture	Client Device (`LocalStorage` / `IndexedDB`)	Personalizing dashboard greetings, filtering relevant exam modules, and generating scorecard headers.
2. CBT & Quiz Telemetry	Attempted Questions, Selected Options, Time Spent per Question, Negative Marking Deductions, Bookmarks	Client Device (`LocalStorage` / `IndexedDB`)	Calculating diagnostic accuracy, tracking historical progress, and enabling revision of bookmarked questions.
3. Communication & Support Data	Email Address, Phone Number (only if voluntarily emailed or submitted for support/alerts)	Encrypted Official Email Inbox	Resolving technical bugs, answering answer-key queries, sending critical platform updates, PWA installation alerts, or OTP verifications.
4. Device & Network Log Data	Anonymized IP Address, Browser Type/Version, OS Version, Screen Resolution, Referring/Exit Pages, Timestamps	Edge CDN & Security Firewall Logs	Optimizing responsive mobile/desktop UI, enforcing rate-limiting, preventing automated scraping, and mitigating DDoS attacks.
5. Advertising & Analytics Cookies	Google DoubleClick DART Cookie, AdSense Identifiers, Aggregated Page-View Metrics	Browser Cookie Store (Managed by Consent Settings)	Displaying non-intrusive advertisements via Google AdSense to keep our study materials free for students, and measuring site traffic.

3.1 Strict "Zero Data Sale" Policy: BR DOT HUB strictly adheres to a Zero Data Sale Policy. We NEVER sell, rent, lease, trade, or monetize your personal contact details or academic records to third-party telemarketers, coaching institutes, or data brokers under any circumstances. (हम किसी भी छात्र का निजी डेटा किसी भी कोचिंग संस्थान या मार्केटिंग कंपनी को कभी नहीं बेचते हैं।)

🤖 Section 4: Third-Party AI Data Processing & API Transmission ("Ask AI" Feature)

4.1 Step-by-Step External API Routing: BR DOT HUB integrates an interactive "Ask AI" academic doubt-solving assistant powered by external Large Language Model (LLM) APIs (such as Google Gemini API, OpenAI APIs, or equivalent foundational AI engines). When you type an academic question into the AI chat box and press send:

Your textual query is encrypted in transit using industry-standard HTTPS / TLS 1.3 cryptographic protocols.

The prompt is transmitted via secure API gateway to the respective third-party AI provider strictly to generate a contextual educational explanation, formula derivation, or bilingual summary.

The generated academic response is streamed back to your browser for immediate reading.

4.2 Data Minimization & Strict PII Warning: Our API integration is engineered with strict Data Minimization. We do NOT bundle your local profile details (such as your Name, Roll Number, Exact Geolocation, or CBT Test Scores) with your AI prompts. However, students are strictly warned NEVER to type Personally Identifiable Information (PII)—including Aadhaar numbers, PAN card details, bank account numbers, UPI PINs, passwords, private phone numbers, or home addresses—into the AI chat box. BR DOT HUB bears zero legal liability for any data retention, training usage, or security incidents occurring on the external infrastructure of third-party AI providers. (छात्रों को सख्त हिदायत दी जाती है कि वे AI चैटबॉक्स में केवल पढ़ाई से जुड़े सवाल पूछें और कभी भी अपना आधार नंबर, बैंक डिटेल, पासवर्ड या निजी जानकारी दर्ज न करें।)

4.3 Cross-Border API Processing Acknowledgment: By utilizing the "Ask AI" tool, you explicitly acknowledge and consent that your text prompt may be processed on cloud inference servers located outside the Republic of India, governed by the respective security and privacy frameworks of those global technology providers.

To sustain server infrastructure, research high-quality study materials, and provide free CBT mock tests to thousands of students across India without charging mandatory subscription fees, BR DOT HUB displays advertisements served by Google AdSense and certified third-party advertising partners.
