These Terms and Conditions (the "Terms") form a legally binding contract between Sigmoid Vedanta Technologies (the "Company", "we", "our" or "us") and you, the user (the "User" or "you") of the Rig Veda – Sacred Knowledge Portal (the "Service"). By accessing or using the Service in any manner, you confirm that you have read, understood and agreed to be bound by these Terms, our Privacy Policy and the description of the Service set out at Services.

1. Acceptance & eligibility

These Terms take effect when you first access the Service, register an account, make a payment, or accept them by ticking a check-box or signing up. You must be at least 18 years of age and competent to enter into a binding contract under the Indian Contract Act, 1872. If you use the Service on behalf of an organisation, you represent that you are duly authorised to bind that organisation, and "you" refers to that organisation as well.

2. Accounts & access

1. You agree to provide accurate, current and complete information when creating an account and to keep it updated.
2. You are responsible for safeguarding your credentials. We will treat any action taken through your account as taken by you.
3. We may suspend or terminate accounts that breach these Terms, that appear to engage in fraudulent or abusive conduct, or that are inactive for a prolonged period, without prior notice.

3. Licence & permitted use

Subject to your compliance with these Terms, we grant you a limited, revocable, non-exclusive, non-transferable and non-sublicensable licence to access and use the Service for personal, non-commercial study, research and devotional purposes. You shall not, and shall not permit any third party to:

• reverse-engineer, decompile or disassemble any part of the Service;

4. Purchases, refunds & access term

1. Paid tiers (currently Pro and Pro Max) unlock additional features as described at /pricing. Each paid tier is a one-time purchase, with no automatic renewal. Pricing, taxes and entitlements may change from time to time; the version in force at the time of your purchase applies.
2. Access term. Subject to clause 8 below, a one-time purchase grants you a non-transferable right to access the purchased tier for a default term of up to two (2) to three (3) years from the date of successful payment, as determined by the Company in its sole discretion. The Company is under no obligation to extend, renew or continue access beyond the term in force at any given time, and is under no obligation to offer any minimum period of access.
3. Reactivation. Upon expiry of the access term, you will revert to the free tier. You may write to us at sigmoidtechnologies@gmail.com to request reactivation. Reactivation is at the Company's sole discretion and may or may not involve a further fee; the Company's then-current reactivation policy (if any) will apply.
4. Payments are processed by Razorpay Software Private Limited and other third-party processors. You authorise us and our processors to charge the payment method you provide for the one-time purchase amount shown at checkout.
5. Refunds are at the sole discretion of the Company. Fees paid for a completed one-time purchase are non-refundable as a matter of right. The Company may, in its sole and absolute discretion and without setting any precedent, issue a full, partial or pro-rated refund where it considers it appropriate to do so. No User shall have any entitlement to a refund except as expressly granted in writing by the Company or as strictly required by applicable law.
6. Free-tier limits, including allowed mandalas and daily chat quotas, are subject to change at our sole discretion.

5. User content & conduct

The Service allows you to submit chat messages, queries, contact-form enquiries and other content ("User Content"). You retain ownership of your User Content but grant us a worldwide, royalty-free, sublicensable licence to host, store, process, transmit and use it to operate, secure, improve and provide the Service, and to enforce these Terms. You represent that your User Content does not infringe third-party rights and is not unlawful, defamatory, obscene or otherwise objectionable.

6. Intellectual property

All software, models, embeddings, knowledge-graph structures, visualisations, designs, trade marks, the name "Sigmoid Vedanta", and all other proprietary material on the Service are owned by, or licensed to, the Company. The Rig Veda hymns themselves are in the public domain; our curated translations, commentary, indexes, embeddings, knowledge graph and software are not.

7. AI-generated content

Parts of the Service rely on large language models and retrieval-augmented generation. AI outputs may be inaccurate, incomplete or out of date and must not be relied upon as religious instruction, scholarly authority, legal advice, medical advice or any other form of professional advice. You are solely responsible for any decisions you make on the basis of AI-generated content.

8. Service availability & discontinuation

1. No minimum guarantee. The Service is offered on a commercially reasonable best-effort basis only. The Company makes no representation, warranty or commitment as to any minimum uptime, minimum service level, minimum lifetime of the Service, or minimum continuity of any specific feature.
2. Right to discontinue. The Company reserves the unconditional right, at its sole and absolute discretion and at any time, to suspend, modify, restrict, limit, degrade or permanently discontinue the Service (in whole or in part, and either generally or for any individual User), with or without prior notice to you and with or without cause. Without limiting the foregoing, the Company may take the Service offline at any time and without prior intimation to any User.
3. Effect on paid users. If the Service is discontinued (in whole or in part) before the expiry of your access term, you will not be entitled to any compensation, damages, credit, set-off or refund as a matter of right; any consideration shown by the Company is governed by clause 4 (refunds are entirely at the Company's discretion).
4. No reliance. You acknowledge that you have not relied on any promise, representation or assurance (whether oral, written or implied) as to the future availability, longevity or feature set of the Service, and that the consideration you have paid takes account of the discretionary nature of continued access.

9. Warranties & disclaimers

The Service is provided "as is" and "as available" without warranties of any kind, whether express, implied or statutory, including warranties of merchantability, fitness for a particular purpose, accuracy, reliability or non-infringement. We do not warrant that the Service will be uninterrupted, error-free, secure or free of harmful components, or that it will remain available for any minimum duration.

10. Limitation of liability

To the maximum extent permitted by law, the Company, its directors, employees, contractors, partners and affiliates shall not be liable for any indirect, incidental, special, consequential, punitive or exemplary damages (including loss of profits, data, goodwill or anticipated savings) arising out of or in connection with your use of, or inability to use, the Service. The Company's aggregate liability for all claims arising in any twelve-month period shall not exceed the amounts you have actually paid to the Company for the Service in that period, or INR 5,000, whichever is lower.

11. Indemnity

Without prejudice to clause 8 (under which the Company may discontinue the Service entirely at any time and without notice), the Company may suspend or terminate your individual access to the Service immediately and without notice, with or without cause, including (but not limited to) for any breach of these Terms, suspected fraud or abuse, prolonged inactivity, or where required by law or by a competent authority. Upon termination, the licences granted to you in clause 3 cease, but clauses 4, 5, 6, 7, 8, 9, 10, 11, 13 and 15 survive.

13. Governing law & jurisdiction
