Terms of Use
Last updated 21 October 2026
These terms apply when you use Primer at primer.tirukamal.com, a service of Tirukamal Innovative Solutions Private Limited (“we”, “us”). By using Primer, you agree to them.
1. What Primer is
Primer turns a topic into a set of study questions grouped by perspective and level. The questions are free. Written answers to the questions are paid, either for one topic or with a plan.
Questions and answers are written by AI models from Anthropic and OpenAI, with web searches where a topic needs current information. They can contain mistakes. Primer is a study aid. It is not medical, legal, financial or other professional advice; check anything important with a qualified person or a reliable source.
2. Who can use it
You must be 18 or older, or use Primer with the consent of a parent or guardian.
3. Your account
- You sign in with a one-time code sent to your email address. Keep access to that email secure, as anyone who can read it can sign in as you.
- Give a real email address that you control. One account is for one person.
4. Topics are public
When you build a primer, the topic you type and the questions written for it are shown publicly on Primer and may appear in the list of recent primers. Don’t type personal, confidential or sensitive information as a topic. Answers are shown only to people who have unlocked them.
5. Prices and payment
- Prices are shown in Indian rupees on the pricing page and before you pay. They are the full amount you pay. We are not registered for GST at present, so no GST is charged; if that changes, we will tell you before GST is added to any payment.
- Payments are processed by Razorpay. We don’t see or store your card, UPI or bank details.
- One-topic purchases unlock the answers for that topic, with no time limit while Primer runs. Plans unlock answers for a set number of topics within their period (for example, 20 topics in 30 days). Unused topics expire at the end of the period. Plans don’t renew automatically.
- Payments are non-refundable except as set out in our Cancellation and Refund Policy or where the law requires a refund.
- We may change prices and plans. A change doesn’t affect anything you have already paid for.
6. Fair use
You agree not to:
- use Primer for anything unlawful, or to build primers meant to harass, defame or harm anyone;
- try to get around limits, payments or security, or use automated tools to scrape or overload Primer;
- resell or republish answers in bulk, or present them as your own professional advice.
You may use questions and answers for your own study, teaching and notes.
7. Availability and changes
We work to keep Primer available, but we don’t promise it will always be uninterrupted or error-free. We may add, change or remove features, and limit how many free primers can be built in a period.
8. Our intellectual property
Primer’s software, design, name and logo belong to Tirukamal Innovative Solutions Private Limited.
9. Disclaimers and liability
Apart from what these terms expressly say, Primer is provided “as is”, without warranties of any kind, to the extent the law allows. We are not liable for indirect or consequential losses, or for decisions you make based on its content. Our total liability for any claim is limited to the amount you paid us in the 12 months before the claim arose.
10. Suspension
You can stop using Primer at any time. We may suspend an account that breaks these terms or puts Primer or other users at risk.
11. Governing law
These terms are governed by the laws of India. The courts at Pune, Maharashtra have exclusive jurisdiction over any dispute relating to them or Primer.
12. Changes to these terms
We may update these terms. If a change is significant, we will say so on Primer or by email before it takes effect.
