⚙️ 2. Step-by-Step Guide: How Our Support & Bug Resolution Workflow Operates (हमारी शिकायत और सहायता प्रक्रिया कैसे काम करती है)

To help our engineering and academic teams resolve your issue as fast as possible, please follow this simple 4-step workflow when reaching out to us:

Step 1 — Identify Your Query Category & Subject Line (सही विषय का चुनाव करें):

For Answer Key or Study Note Corrections: Email [supportbrdothub@gmail.com](mailto:supportbrdothub@gmail.com) with the subject line [Academic Review] - Exam Name & Test/Note Title. Include the exact Question Number, what you believe the correct answer is, and a photo or citation from an NCERT/standard textbook.

For Technical Glitches (CBT Timer, UI, or PWA Issues): Email [supportbrdothub@gmail.com](mailto:supportbrdothub@gmail.com) with the subject line [Tech Support] - Device & Browser Name. Mention your device model (e.g., Android Chrome) and attach a screenshot of the screen if possible.

For Leaderboard Appeal (Flagged Attempt): If your CBT attempt was marked 'Disputed' due to accidental tab-switching or a network drop, email [adminbrdothub@gmail.com](mailto:adminbrdothub@gmail.com) within 7 calendar days with your Profile Name and Test Name.

Step 2 — Automated & Manual Ticket Logging (टिकट पंजीकरण - 24 घंटे के भीतर): Once your email reaches our helpdesk, our support team logs your query and sends an electronic acknowledgment within 24 hours.

Step 3 — Academic / Technical Audit (जांच और सुधार): For academic queries, our subject matter reviewers cross-check the question against official answer keys and NCERT sources. For technical issues, our lead developer inspects the client-side routing or JSON schema.

Step 4 — Resolution & Live Deployment (समाधान और अपडेट): Verified corrections are pushed directly to our live repository (master.json / Markdown files), and a confirmation reply is sent to your email address.

⚖️ 3. Statutory Grievance Redressal Mechanism (कानूनी शिकायत निवारण तंत्र)

❓ 4. Quick Self-Service Troubleshooting FAQ (त्वरित समाधान प्रश्नोत्तरी)

Q1: How can I delete my saved profile and test history? (मैं अपना प्रोफ़ाइल और टेस्ट रिकॉर्ड कैसे मिटा सकता हूँ?)

Answer: Because your profile and test scores are stored locally inside your own browser, simply go to your Dashboard Settings and click the "Delete Profile" button, or clear your browser's site data for brdothub.in. Your data will be wiped instantaneously.

Q2: Why did my previous CBT test history disappear after I formatted my phone or cleared Chrome cache? (फ़ोन फॉर्मेट या ब्राउज़र क्लियर करने पर मेरा पुराना रिकॉर्ड क्यों हट गया?)

Answer: To guarantee 100% student privacy, BR DOT HUB uses a Decentralized LocalStorage Architecture rather than storing your personal test records on external cloud servers. Clearing browser storage removes local records permanently.

Q3: How can I manage or opt out of personalized Google AdSense ads? (मैं विज्ञापनों की सेटिंग कैसे बदल सकता हूँ?)

Answer: You can customize or opt out of personalized Google ads anytime by visiting https://adssettings.google.com, as explained in Section 5 of our [Privacy Policy](/privacy).
