Mentron Crack BITS WILP — AI-ML Field Guide

The short version

Four things worth knowing

We never see your card or UPI details. The payment is completed on Razorpay’s servers. We receive a payment reference and the amount.
Your progress is stored against your account, not in your browser — so you can pick up on another device.
If course chat is enabled and you use it, your question goes to Google’s Gemini API. The providers below also process the data needed to host and operate the site.
We do not sell, rent or share your data for advertising, and we run no advertising or analytics trackers.

The detail

What we collect

What	The fields	Why
Your account	Email address. Your password is stored by our authentication provider as a hash — we never receive or store it.	To sign you in and to tie a purchase to you.
Your purchase	Course, payment reference, payment id, amount in paise, and the date.	To give you access, to show it at your account, and to keep the sales record the law requires.
Your session	A random session token, a short label for how the session started (“web-login”, and so on), and timestamps. It is not a device fingerprint.	To enforce the one-device-at-a-time rule.
Your progress	Which pages you marked complete, which practice questions you ticked, whether a worked example is revealed, and how far through a walkthrough you are.	To resume where you left off on another device.
Your chat	Your questions, the answers, the citations behind them, your preferred mode, the topics you have seen, and a run log (which step ran, how long it took, whether it failed). The run log stores identifiers and scores, not the text of the textbook chunks.	To answer you, to keep a history you can come back to, and to find out when something breaks.
Your error reports	The page, the category, your note, and the sentence you had selected when you pressed the button. Anonymous reports also store a hash of your network address, used only to slow down spam.	To find and fix the error you reported.
A cheat-sheet request	Your email address, the requested sheet and the capture time, stored in our database. The endpoint logs the sheet and storage outcome, not your email address.	To record your request. The sheet opens on the site; no email is sent and this form does not subscribe you to marketing updates.
Rate-limit counters	Your account or a pseudonymous hash of your network address, the endpoint, and a count inside a short time window. Anonymous report and cheat-sheet requests use the hash.	To stop abuse without getting in your way.

Third parties

Who else sees it

Our database and authentication provider. It holds the rows above on our behalf, in a region outside India (Seoul), under a processing agreement.
Razorpay. It takes the card or UPI details, confirms the payment, and hands back a reference. It does not see your course progress.
Google, if you use the course chat. Your question text is sent to the Gemini API to be embedded and answered.
The retrieved textbook passages go with it. If you never open the chat, nothing is sent.
Our hosting provider. It sees the requests that reach the site, including your network address, as any web host does.

We do not use advertising networks, tracking pixels, or third-party analytics scripts. We do not sell or rent your data.

What is stored on your device

Sign-in cookies. Keep you signed in and help manage one active device at a time.
Display preferences. Your browser remembers your light, dark or system theme.
Local study data. Flashcard reviews and Brain Dump notes stay in this browser. They do not automatically sync across devices.
Chat, if enabled. Your browser may remember a chat shortcut; the conversation is stored on our servers.

You can clear this data in your browser’s site settings. This may sign you out and remove local study notes or review history. Account-saved course progress is stored separately. We do not use advertising cookies or fingerprinting.

Retention

How long we keep it

Purchase records — for as long as accounting and tax law requires us to keep a record of a sale.
Everything else — progress, chat history, profile, reports — stays until you delete it or close your account.
Server logs — kept for a short operational window and then rotated away.
Cheat-sheet requests are stored separately from accounts. They remain until removed during maintenance or at your request; closing an account does not automatically remove them. Email us to request deletion using the address you supplied.

Your call

Your rights

Ask what we hold. Write to us and we will tell you what is stored against your account.
Ask us to correct it. If something is wrong, we will fix it.
Ask us to delete it. We delete your progress, chat history and profile on request. You can also ask us to remove a cheat-sheet request, including without an account.
Purchase records are the exception. We keep what the law requires, and we say so rather than pretend otherwise.
Withdraw consent. For anything that is not a purchase record, stopping the processing stops the collection.

Write to nithish.s@mentron.in. We acknowledge within 48 hours and respond within 30 days.

How it is kept

Security

Row-level security on every table. A query signed in as you can only read your own rows.
The service-role key never reaches the browser.It is server-only, and the pages are compiled without it.
No card data anywhere in our systems. It goes straight to Razorpay and never touches our database.
Payments are verified by signature. A webhook that does not verify is rejected.

Changes

If this page changes

If we change what we collect or who we share it with, this page changes first, with a new date at the top. If the change affects what you have already given us, we will write to you before it takes effect.
