1. Introduction & Overview
Welcome to OAV Bibina Knowledge Hub ("we", "our", "us"). We are committed to protecting the privacy of students, teachers, and visitors who access our online educational resources, notes, and study tools.
This Privacy Policy explains how information about you is collected, used, disclosed, and safeguarded when you visit our website. By using OAV Bibina Knowledge Hub, you agree to the collection and use of information in accordance with this policy.
2. Information We Collect
a. Non-Personal & Technical Data
When you browse our platform, our servers and service providers automatically collect standard web log data, including your IP address, browser type, operating system, referring URLs, pages visited, and time spent on pages.
b. Search & AI Queries
Queries entered into our quick search bar (Command Palette) and text prompts submitted to our AI Academic Assistant (Chatbot Panel) are processed to provide real-time responses and study guidance.
c. Administrative Authentication
For administrative operations, encrypted session tokens are stored via HTTP-only cookies to verify authorized access. No public user registration or personal identification is required for general student access to study notes.
3. Third-Party Integrations & Services
To provide a fast, secure, and free educational platform, we integrate several trusted third-party services. These services operate under their respective privacy policies:
We use Google AdSense (Client ID: ca-pub-4918829673874789) to display advertisements on our website.
- Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to our website or other websites.
- Google's use of advertising cookies enables it and its partners to serve ads based on your visit to our site and/or other sites on the Internet.
- Users may opt out of personalized advertising by visiting Google Ad Settings or aboutads.info.
Our platform embeds web typography from Google Fonts (fonts.googleapis.com). When your browser loads these fonts, your IP address is processed by Google to deliver the requested asset files.
Our entire infrastructure is hosted on Cloudflare, including Pages Workers, D1 Relational Databases, and R2 Object Storage for secure document downloads via signed URLs.
- Cloudflare provides CDN edge caching, DDoS security mitigation, and performance monitoring.
- Cloudflare may process operational log data (IP addresses, request headers, SSL handshakes) to secure network traffic against threat vectors.
To protect administrative actions and submission forms against automated spam and attacks, we utilize Cloudflare Turnstile. Turnstile verifies human interactions without using intrusive tracking cookies or interactive puzzle CAPTCHAs.
Our academic search assistant leverages Cloudflare Workers AI inference models to answer student study questions. Prompts submitted to the assistant are processed ephemerally to generate answers and are not linked to your personal identity or saved for public training.
