1. Overview & Commitment

Welcome to RRB Success. We respect your privacy and are committed to protecting the personal information you share with us. This Privacy Policy explains how we collect, use, store, and safeguard your data when you use our mobile application and backend services.

2. Information We Collect

We collect only the minimal information necessary to deliver, personalize, and maintain your exam preparation experience:

Account Credentials: When you register an account, we collect your full name, email address, password hash (encrypted securely using bcrypt), and generate a unique user identifier (UUID).
Authentication & Session Data: We issue secure JSON Web Tokens (JWT) for session authentication. Passwords are never stored in plain text. All data transmission between your app and server is encrypted using TLS 1.3 HTTPS protocols.
Study Progress & App Data: We store your exam selections, chapter completion progress, practice workout logs, CBT mock test scores, and performance analytics on our secure servers to track your learning journey. For registered, authenticated accounts, your study bookmarks, spaced revision schedules, and diagnostic mistake notebook entries are synchronized securely to our cloud database to enable seamless cross-device learning; for guest users, these remain strictly local on your device's private application storage.
Google Play Billing Data: When you purchase an exam subscription (e.g. ₹299/month per exam), purchase transactions and subscription entitlements are processed securely by Google Play Services. RRB Success receives confirmation tokens and entitlement status. We do not collect or store credit cards, bank accounts, or financial credentials.
AdMob Advertising Identifiers: Google AdMob SDK displays non-intrusive advertisements in accordance with our policy-driven rules (including ads-free grace periods for guest/new users and ad-blocking on protected chapter content). AdMob may collect anonymous device advertising IDs (GAID), IP address, and standard diagnostic logs for ad delivery, fraud detection, and frequency capping.

3. How We Use Your Information

Your data is strictly utilized for legitimate educational operational purposes:

To maintain, personalize, and synchronize your exam preparation progress across devices.
To verify subscription status and unlock entitled exam study materials via Google Play Billing.
To send essential transactional notifications (such as password reset links) via ZeptoMail.
To ensure platform security, prevent unauthorized access, and enforce rate limits.
To serve policy-driven, non-intrusive advertisements via Google AdMob where applicable.

4. Transactional Communications

We send transactional emails (such as account verification and password reset requests) using ZeptoMail (Zoho Corporation) from support@pijush.in. We do not sell your email address to third parties or send unsolicited marketing emails.

5. Data Retention & Security

Your personal account data and study records are stored in a secure PostgreSQL database on isolated production servers (api.pijush.in). We enforce Strict Transport Security (HSTS), CORS restrictions, rate-limiting, and standard security headers.

Your information is retained for as long as your account remains active. You may request account deletion at any time.

6. Account Deletion Rights

You have the absolute right to delete your account and associated personal data. You can delete your account inside the mobile app (under Profile Settings) or submit a deletion request online at Account Deletion Page.

Upon deletion request processing, your profile data, email, password hash, server-stored study records, test history, and synchronized cloud bookmarks/revision entries are immediately and permanently purged from our active database (0 days retention for personal records). Client-local cached data stored on your device can be cleared at any time by clearing application data or uninstalling the app.
