Cookie Policy

Last updated: June 7, 2026

1. Legal Directive & Operational Scope

This Comprehensive Tracking & Cookie Consent Policy ("Policy") governs the storage, reading, and structural transmission of small client-side data packets—including HTTP cookies, web beacons, local storage arrays, and session identifiers—upon your access to the web portal https://engiprephub.in ("EngiPrepHub," "We," "Our," or "Us").

We conform strictly to global data protection laws, including the European Union’s General Data Protection Regulation (GDPR), the California Consumer Privacy Act (CCPA) as amended by the California Privacy Rights Act (CPRA), and the Indian Digital Personal Data Protection Act (DPDP Act, 2023). This Policy details why we use tracking mechanisms, how third-party platforms (like Google AdSense and Supabase) interact with your browser, and how you can exercise full control over your digital footprint on our site.

2. The Technical Science Behind Web Cookies & Persistent Objects

To help you build a solid understanding, we have compiled a quick overview of the technical architecture used by web browsers to manage state across stateless HTTP communication models:

HTTP-State Mechanics

By default, the Hypertext Transfer Protocol (HTTP) is completely stateless. Every request from your machine is treated independently. Web developers use state vectors to remember logged-in students and saved preferences across actions.

  • Standard HTTP Cookies: Key-value strings dispatched via the Set-Cookie header from origin servers. Browsers store these strings locally and append them to subsequent outbound queries in the Cookie header.
  • Local Storage & Session Storage (Web Storage API): Native client-side databases that let developers store key-value tables. Unlike cookies, Web Storage objects are never transmitted inside network headers, maximizing bandwidth efficiency.
  • Web Beacons / Tracking Pixels: Transparent 1x1 GIF images loaded from dynamic endpoints. Loading the image tells external engines (like Google metrics) that a specific IP opened our study guides.

3. Explicit Classification of Cookies Leveraged by Our Platform

We do not clutter your machine with arbitrary tracking strings. The cookies we utilize are categorized into four logical types:

Cookie Identifier & Key name Provider Domain Classification Typology Retention Lifespan Primary Purpose Description
sb-access-token Supabase Auth Strictly Necessary Session Ends Maintains your authenticated student state securely.
_ga Google Analytics Performance/Analytical 2 Years Assigns a randomized ID to track syllabus usage metrics.
__gads Google AdSense Targeting/Advertising 13 Months Delivers personalized ads in conformance with AdSense regulations.
engi-theme-preference EngiPrepHub (Local) Functional Preference Persistent Remembers your preference for dark/light mode rendering.

4. Comprehensive Disclosures Regarding Google AdSense & DoubleClick Advertising

To fund our academic resource curation, We place non-intrusive banner advertisements on public notes and syllabus layouts through Google AdSense. In doing so, Google utilizes tracking cookies to serve targeted context matches:

You can easily opt out of personalized advertising globally by visiting Google's official ad configuration portal at Ads Settings, or by using a regional privacy blocker.

5. Regional Regulatory Disclosures (Your Rights)

GDPR (European Union)

Consent First (Opt-In)

Under GDPR mandates, all non-essential analytical or targeting trackers are fully blocked by default until you click "Accept" on our consent banners. You retain the absolute right to withdraw consent at any time.

CCPA & California Rights

Do Not Sell My Info

We do not sell student profile data to data brokers. However, California law considers the integration of targeted ad trackers to be a "share" of data. Use our footer settings to toggle ad personalization.

DPDP Act (India)

Direct Transparency

In alignment with Indian DPDP Act parameters, all student personal identifiers are securely maintained under data-minimization models. No analytical processing occurs without clear context.

6. Frequently Compliance Questions (FAQs)

What happens if I block analytical and targeting cookies?

Nothing breaks. Our core notes databases, syllabus structures, search parameters, and calculators will continue to function. The only difference is that the advertisements displayed will be general, rather than tailored to your branch.

How can I clear saved cookie markers from my system right now?

Open your web browser settings and search for "Clear browsing data / Cookies". Select EngiPrepHub and click delete. This instantly flushes all cookie strings and session indices from your browser.
