Terms of Use and User Agreement

1. Operator and Contracting Party

The Platform is owned and operated by Dr. Mohammad Yousuf Jamal, carrying on business as a sole proprietor under the trade name "YarvixLab" ("YarvixLab", "we", "us" or "our"). The current principal business address and official contact particulars are displayed in the Contact or Legal Notice section of the Platform and, where applicable, on invoices. The user, purchaser, learner and, where applicable, the learner's parent or lawful guardian are referred to as "you" or "your".

Dr. Mohammad Yousuf Jamal is the contracting party. The same legal name should appear consistently on invoices, payment receipts, applicable tax records and the payment-gateway account. YarvixLab is the trade name of the business and is not a separate legal entity.

2. Acceptance and Order of Documents

You accept these Terms by clicking an acceptance checkbox, creating an account, making a purchase, downloading or installing an application, or continuing to use the Platform after being given a reasonable opportunity to review these Terms. If you do not agree, do not use or purchase the Platform.

Your order summary, the access period and product description displayed at checkout, any plan-specific terms, the Refund and Cancellation Policy, and the Privacy Policy form part of the agreement. If there is a conflict, the checkout page and order confirmation control for price, purchased content and access period; the Refund and Cancellation Policy controls for refund procedure; the Privacy Policy controls for personal-data processing; and these Terms control for all remaining matters. Mandatory law always prevails.

3. Eligibility and Learners Under 18

A person may enter into a purchase contract only if legally competent to contract. A learner under 18 may use the Platform only with the involvement, permission and supervision of a parent or lawful guardian. The parent or guardian must make or authorise purchases and must provide any consent required for processing the learner's personal data.

We may request reasonable age, identity or parental-authority verification where required by law or necessary to protect learners. If valid consent or verification is not provided, we may restrict account features, decline a purchase or suspend personal-data processing, while honouring any non-waivable rights relating to an existing paid order.

4. What the Platform Provides

YarvixLab provides educational Physics content and learning tools, which may include concept animations, interactive labs, core concepts, derivations, formula explorers, solved examples, guided practice, independent practice, quizzes, real-world applications, units and constants, shortcuts, and learning-scope summaries.

Offerings may include a free chapter, individual chapter access, grouped or class-level access, a complete-course bundle, a fixed-term plan, or another clearly described product. Features, content depth and availability may differ by product, device, location and release version. The exact paid entitlement is only what is described in the checkout page and order confirmation.

5. Purchases, Prices and Payment

Prices, taxes, currency, access period and included content will be shown before payment. You authorise us and our payment service providers to process the amount shown for the selected order. Payments may be accepted through UPI, cards or other methods made available at checkout. A payment service provider is not the provider of the educational content.

An order is confirmed only after successful payment authorisation and issuance of an order confirmation or activation of access. If money is debited but access is not activated, contact the Grievance Officer with the transaction reference. Duplicate payments will be refunded after verification. Currency-conversion, bank, card or cross-border charges imposed by a third party are your responsibility unless applicable law states otherwise.

We may correct an obvious pricing or description error before accepting an order. We will not increase the price of an already accepted fixed-price order retrospectively. Any future recurring plan will require clear affirmative consent and will disclose the renewal amount and cancellation method before enrolment; no recurring billing applies unless expressly selected by you.

6. Access Period; No Lifetime or Perpetual-Service Promise

Every paid product is a limited right of access for the period expressly displayed at checkout and repeated in the order confirmation (the "Access Period"). We do not promise access for the user's lifetime, the owner's lifetime, or forever. Words such as "buy", "purchase" or "complete course" describe the selected digital access package and do not transfer ownership of the Platform or create a perpetual hosting, maintenance, update or support obligation.

If no Access Period is displayed at checkout, do not complete the purchase and contact us for clarification. No lifetime or perpetual access may be inferred from silence, advertising shorthand, a one-time payment, prior availability, or continued use after purchase.

Access ends automatically when the Access Period expires, when the relevant offering is lawfully terminated under these Terms, or when access can no longer be provided because of a lawful discontinuation described below. Continued access after expiry is not a waiver and may be removed without creating a renewal or permanent right.

7. Personal Licence and Access Restrictions

Subject to payment and compliance with these Terms, we grant you a limited, personal, revocable, non-exclusive, non-transferable and non-sublicensable licence to access the purchased content during the Access Period for the learner's private educational use. Each account is for one learner unless a family, school or institutional plan expressly states otherwise.

You must not share credentials; resell, rent or transfer access; reproduce or redistribute substantial content; publish answer banks; screen-record or download content except through an authorised feature; remove watermarks or rights notices; scrape or systematically extract content; train an AI or machine-learning model on Platform content; reverse engineer the Platform; bypass payment or access controls; interfere with security; introduce malicious code; impersonate another person; or use the Platform for an unlawful, abusive or commercially competing purpose.

8. Free Content, Trials and Promotions

Free chapters, previews, trials, coupons and promotional access may be introduced, changed, limited or withdrawn at any time. They do not create a right to future free content or a promise that the same features will remain free. Promotional terms shown with an offer apply in addition to these Terms. We may prevent repeated or abusive use of trials or promotions.

9. Refunds, Cancellations and Failed Access

Digital educational access may be made available immediately after payment. Except where our Refund and Cancellation Policy or applicable law provides otherwise, a change of mind after access has been activated or content has been materially used does not automatically qualify for a refund.

We will consider a refund or other legally appropriate remedy for a duplicate charge, payment without activation, material misdescription, or a verified material technical failure that we are unable to resolve within a reasonable time after receiving sufficient information. Refund requests must be made through the current refund or support contact method displayed on the Platform and include the order reference and a description of the issue. Approved refunds will be sent to the original payment method within the period required by applicable law and payment-system rules.

Nothing in these Terms limits a remedy, refund or complaint right that cannot lawfully be excluded. A separate Refund and Cancellation Policy must be displayed before payment and will provide the operational time limits and process.

10. Educational Purpose; No Result Guarantee

The Platform is an educational aid and not a school, university, examination authority, professional certification body, personalised tutor, engineering consultancy or safety service. It does not replace formal instruction, prescribed textbooks, teacher guidance or independent study.

We do not guarantee marks, grades, ranks, admissions, examination selection, completion, improvement, scholarships, employment or any other academic or career outcome. Results depend on many factors outside our control, including the learner's effort, prior knowledge, curriculum, examination pattern and use of the Platform. Progress indicators, quiz scores and recommendations are informational and may not reflect official assessment standards.

11. Accuracy, Simulations and Responsible Use

We use reasonable efforts to prepare accurate content, but educational material may contain errors, omissions, simplifications or outdated references. Simulations and animations may use idealised models, rounded values, assumed conditions or approximations and may differ from real-world measurements. You should verify important formulas, constants and conclusions against authoritative sources and report suspected errors to us.

Platform content must not be used as the sole basis for laboratory safety, medical, legal, financial, engineering, construction, industrial or other high-risk decisions. Do not attempt a physical experiment without appropriate equipment, supervision and safety procedures.

12. Availability, Maintenance, Changes and Discontinuation

The Platform is provided through evolving technology and depends on hosting, networks, devices, browsers, app stores, payment systems and third-party services. We do not guarantee uninterrupted, error-free, secure or universally compatible operation. Maintenance, security incidents, connectivity failures, legal requirements and events outside our reasonable control may interrupt access.

We may correct, update, replace, reorganise or remove content and features; change technical requirements; suspend new sales; or discontinue all or part of the Platform for educational, technical, security, legal or commercial reasons. We have no obligation to operate, host, maintain, update or support the Platform indefinitely or for any person's lifetime.

For a planned material discontinuation that substantially prevents use of paid content during an unexpired Access Period, we will use reasonable efforts to give advance notice and, where required by applicable law, offer a legally appropriate remedy such as continued access for a transition period, comparable replacement access, or a proportionate refund for the materially unavailable remainder. Advance notice may not be possible for emergencies, security threats, insolvency, loss of essential third-party services, force majeure or a binding legal or regulatory requirement.

13. Website, App and Device Requirements

You are responsible for a compatible device, supported browser or operating system, internet connection, data charges and software updates. We may stop supporting older devices, browsers or operating-system versions where reasonably necessary for security or functionality.

A future mobile application may require updates and device permissions that are explained when requested. If obtained through an app store, the app-store terms also apply. The app store may distribute the application or process payments but is not responsible for our educational content, support or promises, except to the extent its own mandatory terms state otherwise.

14. Accounts and Account Security

You must provide accurate information, keep it current, protect login credentials and promptly notify us of suspected unauthorised use. You are responsible for activity through your account to the extent caused by your failure to use reasonable security. We may use reasonable measures to detect account sharing, fraud, security threats or abuse.

Do not create an account using another person's identity or contact details without authority. We may merge, restrict or remove duplicate, fraudulent or compromised accounts after reasonable verification, subject to applicable law and paid-access rights.

15. Intellectual Property

The Platform and its content, including text, questions, explanations, audiovisual material, animations, simulations, code, interface, design, databases, branding, logos and compilations, are owned by or licensed to us and are protected by applicable intellectual-property laws. Except for the limited licence in these Terms, no right, title or interest is transferred to you.

If you send feedback or suggestions, you grant us a worldwide, royalty-free, transferable, sublicensable and perpetual licence to use them without obligation to compensate you, provided we do not publicly identify you without permission. This clause does not transfer ownership of your personal data.

16. Third-Party Services and Links

The Platform may use or link to third-party hosting, analytics, authentication, content-delivery, payment, communication or app-store services. Their independent terms and privacy practices may apply. We are not responsible for a third party's independent service, content, outage, security or decision, but this does not remove any responsibility that applicable law places on us for selecting or using service providers.

17. Privacy and Data Security

Our Privacy Policy explains what personal data we collect, why we use it, how long we retain it, service providers and transfers, security measures, learner and parent choices, and how to exercise applicable data rights. The Privacy Policy is incorporated into these Terms but consent to unrelated optional data processing will be obtained separately where required.

We apply reasonable safeguards, but no online system is completely secure and we cannot guarantee that a cyberattack, unauthorised act or technical failure will never occur. This security statement does not reduce any statutory security, breach-notification, child-data or grievance obligation. A parent or guardian must provide verifiable consent for a child's personal data where applicable law requires it.

18. Suspension and Termination

We may warn, restrict, suspend or terminate access where we reasonably believe there is non-payment, fraud, credential sharing, infringement, unlawful conduct, a serious security risk, abuse of the Platform, or a material breach of these Terms. Where appropriate, we will provide notice and an opportunity to cure; immediate action may be taken for urgent security, legal, child-safety or fraud concerns.

If we terminate for your material breach, you may lose remaining access without refund to the extent permitted by law. If we terminate without your breach and this materially prevents paid use during an unexpired Access Period, we will provide any remedy required by applicable law. Clauses that by their nature should survive, including intellectual property, disclaimers, liability, indemnity and dispute provisions, remain effective.

19. Disclaimer of Warranties

To the maximum extent permitted by law, the Platform is provided on an "as available" basis. We disclaim implied warranties or conditions of uninterrupted availability, fitness for a particular academic objective, compatibility, error-free operation and non-infringement, except where a warranty or condition cannot lawfully be excluded. Specific written promises in an accepted order remain binding.

20. Limitation of Liability

To the maximum extent permitted by law, we will not be liable for indirect, incidental, special, exemplary, punitive or consequential loss; loss of marks, rank, admission, opportunity, profit, goodwill or data; or loss caused by an examination decision, reliance on an idealised simulation, an unsupported device, your internet connection, your breach, or a third party outside our reasonable control.

To the maximum extent permitted by law, our aggregate liability arising from or relating to the Platform, an order and these Terms will not exceed the total amount actually paid to us by the claimant for the affected offering during the 12 months immediately preceding the event giving rise to the claim.

Nothing in these Terms excludes or limits liability for fraud, fraudulent misrepresentation, wilful misconduct, gross negligence, death or personal injury caused by negligence where such liability cannot be excluded, a statutory personal-data obligation, or any consumer right or other liability that applicable law does not permit us to exclude or limit.

21. Indemnity for Misuse

To the extent permitted by law, you will indemnify and hold us harmless from third-party claims, losses and reasonable costs arising directly from your unlawful commercial redistribution of content, infringement of third-party rights, malicious interference with the Platform, or material breach of the access restrictions. This clause does not require a consumer to indemnify us for our own breach, negligence or unlawful conduct. For a minor's account, this obligation applies to the accepting parent or lawful guardian to the extent legally enforceable.

22. Complaints and Grievance Redressal

Questions, access issues, refund requests and complaints may be sent to the Grievance Officer below. Please include your name, order or account reference, the issue and the remedy requested. We will acknowledge a consumer complaint within 48 hours and aim to redress it within one month, or within any shorter period required by applicable law.

Grievance Officer: Dr. Mohammad Yousuf Jamal | Designation: Proprietor. The current official email address, phone number, postal address and service hours are displayed in the Contact or Legal Notice section of the Platform. Notices sent through the published grievance channel will be treated as notices to YarvixLab.

You may also use any consumer commission, National Consumer Helpline, data-protection authority or other statutory forum available to you. These Terms do not require you to waive a non-waivable complaint or remedy.

23. Governing Law and Disputes

These Terms are governed by the laws of India, without regard to conflict-of-law rules. Before formal proceedings, the parties should attempt in good faith to resolve the dispute through the Grievance Officer for at least 30 days, unless urgent relief or a statutory limitation period requires earlier action.

Subject to mandatory consumer jurisdiction and other non-waivable rights, the courts having jurisdiction under applicable law will have jurisdiction. A consumer may approach a competent consumer commission or other authority as permitted by law. A dispute that is legally arbitrable and is not pursued through a mandatory consumer mechanism may, by mutual written agreement after the dispute arises, be referred to a sole arbitrator under the Arbitration and Conciliation Act, 1996. The parties will agree the seat in writing; proceedings will be in English, and costs will be allocated by the arbitrator.

If you access the Platform outside India, you are responsible for local-law compliance. Any mandatory consumer protection in your country that cannot be waived will continue to apply.

24. Changes to These Terms

We may update these Terms for legal, security, technical or business reasons. The revised version will show a new last-updated date. We will provide reasonable notice of a material change and seek fresh acceptance where required. Changes apply prospectively and will not retrospectively remove a paid entitlement or statutory right. If you do not agree to a material update, you may stop using the Platform and contact us about any unexpired paid access affected by the change.

25. General Terms

These Terms and the incorporated documents are the entire agreement about the Platform and replace prior oral or written statements on the same subject, except for a specific written promise in an accepted order. Our failure to enforce a clause is not a waiver. If a clause is invalid or unenforceable, it will be limited to the minimum extent necessary and the remaining clauses will continue.

You may not assign or transfer your account or agreement without our prior written consent. We may assign the agreement as part of a genuine reorganisation, financing, merger or sale of the Platform, provided the successor assumes the applicable obligations and your mandatory rights are not reduced. Nothing creates a partnership, employment, agency or fiduciary relationship between you and us.

We are not responsible for delay or failure caused by events beyond our reasonable control, including natural disaster, epidemic, war, civil disorder, governmental action, court order, widespread network or cloud failure, cyberattack despite reasonable safeguards, labour disruption or loss of an essential third-party service, but this does not remove remedies required by mandatory law.
