Terms of use

The licence

• A personal, non-transferable licence. You may use the course material to study. That is the whole of what you buy.
• Access lasts as long as the course is served.Access lasts while the purchased course is served, with no scheduled expiry or renewal charge.
• The material stays ours. The textbooks it cites, and the explanations built on them, remain the work of their authors and of us.

What you may not do

• No reselling, no redistribution, no sharing. Not the PDFs, not the pages, not your account. Your licence is personal.
• No scraping or bulk copying to build a competing product, and no passing our content off as your own.
• No interference with the service. Trying to break the paywall, the session lock or the rate limits ends the licence.

This is why the course is tied to one active session at a time. The limit stops one login being resold. It is not a licence-checking scheme, and it is not aimed at you reading on two devices you own.

Sessions and the one-device rule

• One active session at a time. When you sign in somewhere new, the earlier session is ended and you are shown a recovery screen.
• You can take the seat back from that screen at any time, and it takes you straight back to where you were.
• Your account is yours. Keep your email address accurate, and tell us if you lose access to it.

Payment

• One price, one payment. Each course is bought separately, at the price shown when you paid. No subscription, no renewal.
• The price on your invoice is the price you pay.Later changes to the pricing page do not affect a purchase already made.
• Payment is handled by Razorpay. We do not receive or store your card or UPI details.
• If a payment succeeds and access does not arrive, contact us so we can restore access or review a refund under the refund policy.

Errors and corrections

This is study material, and it is re-derived rather than assumed. Where a number, a formula or an answer is wrong, we want to know and we will fix it.

Use the report button on the page. It sends the exact sentence you had selected, which is what lets us find the error instead of guessing at it.

We review reported errors and correct confirmed issues. An individual correction does not automatically qualify for a refund. Substantial access or course problems are reviewed under our refund policy and applicable consumer law.

The refund policy lists the cases.

Availability

We keep the site up and we fix what breaks. We do not promise a service level for study time, and we may change the material as the syllabus and the exam format move.

If a substantial rewrite lands on a course you have already bought, you keep access to it. You do not need to buy again.

Liability

The courses support learning and exam preparation. Results depend on your preparation and assessment; we do not guarantee a particular grade or exam outcome.

Nothing in this policy or our terms limits your rights under applicable consumer law, including any refund or other remedy you are entitled to.

You may use the applicable consumer grievance and dispute-resolution channels if an issue remains unresolved.

Governing law and jurisdiction

These terms are governed by the law of India. A consumer in India may approach the District, State or National Consumer Disputes Redressal Commission under the Consumer Protection Act, 2019.

The grievance officer named on the support page — NITHISH S — can help you resolve an issue.

If these terms change

We will change these terms only to reflect how the service actually works, and the change takes effect from the date shown on this page.

We will not change them in a way that removes a right you already had. If a change would do that we will tell you before it applies to your account.
