Plain-English summary. This is a summary for convenience only — the numbered sections below are the binding agreement.
Professor explains text you select and helps you remember it. You keep ownership of everything you write and save. We charge for Pro. Payments are final and non-refundable — there is a permanent free tier so you can judge the Service before paying, and cancelling before a renewal keeps your access to the end of the term you already paid for. Your statutory consumer rights still apply. Professor uses AI, so it can be wrong — don't rely on it for legal, medical, or financial decisions. If something goes wrong, what we owe you is capped. Indian law applies, and the courts at Mumbai hear disputes.
The Professor browser extension, the readwithprofessor.com website, the web dashboard, and all related services (together, the "Service") are provided by Leanora Ventures Pvt Ltd, a private limited company incorporated under the Companies Act, 2013 (India) ("Leanora", "we", "us", "our"). "Professor" is a product and brand name of Leanora.
"You" means the individual or entity using the Service.
By installing the Professor extension, creating an account, or otherwise using the Service, you agree to these Terms of Service ("Terms") and to our Privacy Policy, which is incorporated into these Terms by reference. If you do not agree, do not use the Service.
If you use the Service on behalf of an organisation, you represent that you are authorised to bind that organisation, and "you" refers to that organisation.
You must be at least 18 years old and legally capable of entering into a binding contract to hold an account. This reflects the Indian Contract Act, 1872, under which an agreement with a minor is void.
If you are under 18, you may use the Service only through an account held and supervised by a parent or legal guardian who accepts these Terms on your behalf and is responsible for your use. We do not knowingly permit users under 13 to use the Service at all. See §14 of the Privacy Policy.
Professor lets you select text on a web page and receive an AI-generated explanation, and lets you save what you learn as flashcards, notes, captured images ("snips"), visuals, and subjects, with the source page recorded. Paid features are described on our pricing page.
The Service is a study aid. It is not professional advice of any kind — legal, medical, financial, tax, or otherwise — and no professional relationship is created by your use of it.
Sign-in is provided through Clerk. You are responsible for maintaining the confidentiality of your credentials and for all activity under your account. Notify us promptly at support@readwithprofessor.com if you believe your account has been compromised.
You may not share, sell, or transfer your account, or use another person's account without permission.
The free tier provides a limited daily allowance of AI explanations and creations, and displays a limited window of lookup history. Current limits are published on the pricing page and in the product. We may change free-tier limits, with reasonable notice for material reductions. Free tiers may also be subject to fair-use protections against automated or abusive consumption (§12).
Pro subscriptions are offered monthly or annually, as selected at checkout, and renew automatically for successive periods until cancelled.
Merchant of Record. Payments are processed by Lemon Squeezy, which acts as the Merchant of Record for the transaction. Lemon Squeezy is the seller of record, and calculates, collects, and remits applicable sales tax, VAT, and GST in your jurisdiction. Lemon Squeezy's terms apply to the payment transaction. We never receive or store your full card details.
Prices are stated exclusive of taxes unless shown otherwise at checkout. We may change prices for future billing periods on at least 30 days' notice; the change takes effect at your next renewal, and you may cancel before then to avoid it.
Cancellation. You may cancel at any time through the customer portal or by emailing us. Cancellation takes effect at the end of the current billing period; you keep Pro access until then, and you are not charged again.
Failed payments. If a renewal payment fails, we may suspend Pro features until payment succeeds, and may downgrade the account to the free tier after a reasonable retry period.
8.1 Payments are final. All payments for the Service — first payments and renewals alike — are final and non-refundable, except as set out in section 8.2 or required by section 8.3. Professor has a permanent free tier, so you can use the Service and judge whether it is worth paying for before you pay anything.
8.2 Refunds at our discretion. We may refund a payment at our discretion, and we will look at any request sent to support@readwithprofessor.com. We would normally expect to refund where a charge was taken in error, where you were charged after cancelling, or where a fault on our side prevented you from using what you paid for. A refund granted in one instance does not create a right to a refund on any later payment, and we may decline a request, and decline to sell you a further subscription, where the pattern of your account indicates this discretion is being used to obtain the Service without paying for it. Where a payment is refunded, your Pro access ends immediately.
8.3 Your statutory rights. Section 8.1 does not override rights you have under the mandatory consumer law of your country of residence, and where those rights apply they prevail over this section.
In particular, if you are a consumer in the European Union or United Kingdom, you have a statutory right to withdraw from a distance contract within 14 days of entering into it. That right arises when you first subscribe; it does not arise again each time an existing subscription renews. Because you ask us to begin providing the Service immediately on purchase, we may, where you exercise that right, deduct an amount proportionate to the Service already supplied to you up to the point of withdrawal, as permitted by the Consumer Rights Directive and the UK Consumer Contracts Regulations.
Nothing in this section affects any other right you may have under applicable law, including any right arising where a subscription renewed without the advance notice that law requires.
8.4 Cancelling instead. Because payments are final, cancelling in time is how you avoid a charge you do not want. You can cancel at any time (§7). Cancelling stops the next payment and leaves your Pro access in place until the end of the term you have already paid for, so cancelling early costs you nothing. Before an annual subscription renews, we send a reminder to the email address on your account in advance of the charge, so that you have notice while you can still act on it. Cancelling is not itself a request for a refund of a payment already taken.
8.5 How refunds are paid. Where a refund is granted, it is issued through Lemon Squeezy, as Merchant of Record, to the original payment method, normally within 5–10 business days.
"Your Content" means the text you select for explanation, and the flashcards, notes, snips, visuals, subjects, tags, and other material you create or store in the Service.
You own Your Content. We claim no ownership in it.
You grant us a worldwide, non-exclusive, royalty-free licence to host, store, reproduce, transmit, display, and adapt Your Content solely to operate, secure, and support the Service for you — including transmitting it to the AI providers listed in the Privacy Policy in order to generate the output you requested. This licence exists only to run the product; it ends when you delete the content or your account, subject to the retention periods in the Privacy Policy.
We do not use Your Content to train AI models, and we do not sell it or share it for advertising.
You are responsible for Your Content, and you represent that you have the necessary rights to submit it and that doing so does not infringe any third party's rights or violate any law.
"Output" means the explanations, generated flashcards, summaries, visuals, and infographics the Service returns to you.
Accuracy. Output is generated by large language models and image models. It may be inaccurate, incomplete, outdated, or misleading, and may misdescribe the source material. You must independently verify anything you rely on. We make no warranty as to the accuracy or fitness of Output (§18).
Rights. As between you and us, and to the extent we hold any rights in Output, we assign them to you, so you may use Output for personal, educational, or internal business purposes. This assignment does not extend to any part of the Output derived from third-party source material you supplied (§11), and does not grant rights we do not hold. Output is not unique — similar input may produce similar output for other users.
No professional advice. Output must not be used as a substitute for advice from a qualified professional, and must not be used to make legal, medical, financial, or safety-critical decisions.
Professor operates on content you choose to select on pages you visit. You are responsible for ensuring that your selection, capture, storage, and export of third-party material — including copyrighted text, images, and material behind a paywall or licence — is permitted by law and by the terms of the site concerned. Professor records source URLs to support provenance and fair dealing, not to authorise copying.
If you believe material stored in the Service infringes your copyright, email support@readwithprofessor.com with the work concerned, the material complained of, your contact details, and a statement of good-faith belief. We will investigate and remove infringing material where appropriate, and may terminate accounts of repeat infringers.
You agree not to:
We may investigate suspected breaches and take the measures in §17.
The Service — including the extension, website, dashboard, backend, user interface, design system, documentation, the "Professor" name and logo, and all related intellectual property — is owned by Leanora Ventures Pvt Ltd and its licensors, and is protected by copyright, trade mark, and other laws.
Subject to these Terms, we grant you a limited, revocable, non-exclusive, non-transferable licence to install and use the Service for your own use. All rights not expressly granted are reserved. You may not use our name or marks without our prior written consent.
If you send us suggestions, feature requests, or other feedback, you grant us a perpetual, irrevocable, worldwide, royalty-free licence to use it without restriction or compensation. We are not obliged to keep feedback confidential.
The Service depends on third parties — including Anthropic, Google, Cloudflare, Clerk, Lemon Squeezy, Plausible, and Sentry — as described in the Privacy Policy. We are not responsible for their acts, omissions, availability, or terms, and their terms may apply to you independently.
The extension is distributed through the Chrome Web Store. Your use of that store is governed by Google's terms; Google is not a party to these Terms and has no obligation to support the Service.
We aim to keep the Service available but do not guarantee uninterrupted or error-free operation. We may modify, add, or remove features, and may impose or adjust technical limits, at any time.
If we discontinue the Service or materially degrade a paid feature, we will give at least 30 days' notice where reasonably practicable, provide a means to export your data, and refund the unused portion of any prepaid subscription period on a pro-rata basis.
By you. You may stop using the Service and delete your account at any time (Dashboard → Settings → Danger Zone), which deletes your data as described in the Data Deletion Policy.
By us. We may suspend or terminate your access, with notice where practicable, if you materially breach these Terms, if required by law, or to protect the Service or its users from security or abuse risk. Where a breach is capable of remedy and the risk allows, we will give you a reasonable opportunity to remedy it first.
On termination for reasons other than your breach, we will refund the unused portion of any prepaid period. On termination, §§9 (as to licences already granted), 13, 14, 18, 19, 20, 23 and 25 survive.
To the maximum extent permitted by applicable law, the Service and all Output are provided "as is" and "as available", without warranty of any kind, whether express, implied, or statutory — including any implied warranty of merchantability, fitness for a particular purpose, accuracy, title, or non-infringement.
We do not warrant that the Service will be uninterrupted, secure, or error-free, that Output will be accurate or complete, or that defects will be corrected.
Nothing in this section limits rights that cannot be excluded under the law applicable to you as a consumer. Some jurisdictions do not allow the exclusion of implied warranties, so parts of this section may not apply to you.
19.1 Excluded losses. To the maximum extent permitted by applicable law, neither party will be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for loss of profits, revenue, goodwill, business opportunity, or data, arising out of or relating to the Service, however caused and on any theory of liability, even if advised of the possibility of such damages.
19.2 Liability cap. To the maximum extent permitted by applicable law, our total aggregate liability arising out of or relating to these Terms or the Service — whether in contract, tort (including negligence), statute, or otherwise — will not exceed the greater of:
Multiple claims do not enlarge this cap.
19.3 Exceptions. Nothing in these Terms excludes or limits either party's liability for: death or personal injury caused by negligence; fraud or fraudulent misrepresentation; wilful misconduct or gross negligence; your breach of §12 (acceptable use) or your payment obligations; or any other liability that cannot lawfully be excluded or limited.
19.4 Consumers. If you are a consumer, you have legal rights that cannot be excluded, and this section applies only to the extent permitted by the consumer law applicable to you. In particular, we do not limit liability for a failure to supply the Service with reasonable care and skill where the applicable law forbids it.
19.5 Basis of the bargain. The pricing of the Service reflects this allocation of risk, and these limitations apply even if a limited remedy fails of its essential purpose.
20.1 By you. You will indemnify, defend, and hold harmless Leanora Ventures Pvt Ltd, its directors, officers, employees, and contractors from and against any third-party claim, demand, action, or proceeding, and any resulting losses, liabilities, damages, penalties, and reasonable legal costs, arising out of or relating to:
20.2 Procedure. We will notify you promptly of any claim for which we seek indemnity, give you sole control of its defence and settlement (except that you may not settle in a way that admits our liability or imposes a non-monetary obligation on us without our written consent), and provide reasonable cooperation at your expense. We may participate in the defence with counsel of our own choosing at our own cost.
20.3 Consumers. If you are a consumer, this section applies only to the extent permitted by the consumer law applicable to you, and never in respect of matters outside your control.
Our processing of personal data is described in the Privacy Policy, which forms part of these Terms and sets out the legal bases, retention periods, international transfer safeguards, your rights, and the Data Deletion Policy.
Where you use the Service to process personal data of others in a business capacity such that we act as a processor on your behalf, contact us to put a data processing agreement in place before doing so.
You represent that you are not located in, ordinarily resident in, or acting on behalf of a person in a country or territory subject to comprehensive trade sanctions, and that you are not a person designated on any applicable restricted-party list. You will not use or export the Service in violation of applicable export control or sanctions laws.
These Terms and any dispute or claim arising out of or in connection with them (including non-contractual disputes) are governed by the laws of India, without regard to conflict-of-law rules.
The courts at Mumbai, Maharashtra, India have exclusive jurisdiction to settle any such dispute, and both parties submit to that jurisdiction.
Consumers. If you are a consumer resident outside India, this clause does not deprive you of the protection of mandatory consumer-protection provisions of the law of your country of residence, nor of your right to bring proceedings in the courts of that country where the applicable law gives you that right. Nothing here limits your right to complain to a data protection or consumer authority in your jurisdiction.
The United Nations Convention on Contracts for the International Sale of Goods does not apply.
We may update these Terms. For material changes we will give at least 30 days' notice before they take effect — by email to the address on your account, or by a prominent notice in the Service — and update the "Last updated" date above.
Changes are not retroactive. If you do not accept a material change, you may cancel before it takes effect and we will refund the unused portion of any prepaid period. Continued use after the effective date constitutes acceptance.
These Terms and the Privacy Policy are the entire agreement between you and us regarding the Service, and supersede all prior understandings on that subject.
If any provision is held invalid or unenforceable, it will be modified to the minimum extent necessary to make it enforceable, or severed if it cannot be, and the remaining provisions continue in full force.
A failure to enforce a provision is not a waiver of the right to enforce it later.
You may not assign or transfer these Terms without our prior written consent. We may assign them to an affiliate or in connection with a merger, acquisition, or sale of assets, on notice to you.
Neither party is liable for a failure or delay in performance caused by events beyond its reasonable control, including acts of God, war, terrorism, civil unrest, epidemic, labour dispute, failure of a utility or telecommunications network, or failure of a third-party provider or cloud platform.
These Terms do not confer rights on any person who is not a party to them, except that §§19 and 20 benefit our directors, officers, employees, and contractors.
We may give notice by email to the address on your account or by posting in the Service. You give notice to us at support@readwithprofessor.com.
Nothing in these Terms creates a partnership, joint venture, agency, or employment relationship.
These Terms are drafted in English. Any translation is provided for convenience; the English version governs.
