Terms of Use.

CaseLens is a service that generates teaching case reports on real companies for use in higher-education classrooms. It is operated by Masa Concept Lab ("CaseLens", "we", "us"). These terms are the agreement between you and us for your use of the CaseLens website and everything you do with it — creating cases, buying student licences, publishing a case, and reading one.

CaseLens is an independent service. It is not published by, endorsed by, or affiliated with any university, business school, or the companies that cases are written about.

They apply alongside our Privacy Policy, which explains what we do with personal information.

By creating an account, generating a case, buying licences, or reading a case someone has shared with you, you accept these terms. If you do not accept them, please do not use CaseLens.

If you are agreeing on behalf of a university, department, or other organisation, you confirm you are authorised to bind it, and "you" means that organisation as well as you personally.

CaseLens is built for educators and their students in higher education. You must be at least 18 years old to create an account. Students you share a published case with do not need an account and are not asked to create one.

We sign you in with a single-use link sent to your email address; there is no password. That makes your email inbox the key to your account, so keep it secure, and use an address you control. We may refuse or close accounts that use disposable or throwaway email domains.

One account per person. Anything done through your account is treated as done by you, so tell us promptly if you think someone else has access to it.

Cases, teaching notes, concept explanations and suggested questions are generated by artificial intelligence from publicly available information and third-party financial data. They are teaching material, produced automatically, and they can be incomplete, out of date, or wrong.

Because of that, and to be as plain as we can about it:

• Every factual claim in a case carries an inline citation, and each case includes a section describing where its data is thin. Please read both, and verify anything you or your students intend to rely on.
• A case is not investment, financial, legal, accounting, or professional advice of any kind, and must not be used as the basis of a decision about a company or its securities.
• Companies written about in a case have no involvement in it. Nothing in a case is a statement by that company, and their names and trade marks are used only to identify and discuss them.
• Financial figures are drawn from third-party data providers and from public sources. We do not warrant that they are accurate, complete, or current.

You are the educator. You decide what reaches your class, and you remain responsible for the teaching you build on a case.

You give us a company name, and optionally your own notes, topic selections, teaching guidance, curated discussion questions, feedback, and — where annotation is enabled — highlights and margin notes. We call all of that your inputs.

Your inputs stay yours. You grant us a licence to store them, send them to the AI and data providers described in our Privacy Policy, and use them to generate, deliver and improve what you asked for. You confirm you have the right to give us what you send, and that it is not unlawful, confidential to someone else, or infringing.

Please do not put personal information about your students, or anyone else's confidential material, into a case request or teaching guidance. Nothing in CaseLens needs it.

We own the CaseLens service — the site, the pipeline, the strategy content layer, the prompts, and the branding — and nothing here transfers any of that to you.

The cases are a different matter, and deliberately so. For a case you have paid for or generated under a free first case, and for the seats you have licensed, we grant you and your licensed students a perpetual, worldwide, royalty-free licence to:

• read, copy, print, store and share the case for teaching, study and research;
• quote from it, adapt it, and build assignments, slides and assessments around it; and
• paste it into AI tools and work with it there, which the case is designed for.

What that licence does not cover is reselling it. You agree not to sell, sublicense or distribute a case as a product of its own, publish it as a case collection, or use it to build or train a competing case-generation service — and, where you give a case to students, to licence a seat for each student you give it to (see below).

You keep the copyright in anything you write yourself, including your teaching guidance, your curated questions, and your and your students' annotations.

A case you generate is private to you until you publish it. Publishing turns on a permanent public URL you can put in a syllabus or LMS, and asks you to declare how many students you are licensing it for. Anyone with that URL can read the case, so treat the link as the access control it is.

The number of seats you declare should honestly reflect the students you are giving the case to. If your class turns out larger, or you reuse the case in a later term, buy additional seats from the case page. Publishing a case and then distributing it beyond your licensed seats is a breach of these terms.

A teaching note is never shown to students, even on a published case; only the discussion questions you actively curate are.

We may publish cases of our own as public samples on the site. Those are ours, and this section does not apply to them.

Prices are shown on the pricing page and at the point of purchase, in pounds sterling. You pay per case rather than by subscription: the case itself, an optional teaching note, a per-student class licence, and an optional annotation add-on on those seats. Each account's first case is free.

The price you are shown when you confirm a purchase is the price that applies to it. We may change prices for future purchases at any time.

Payments are taken by Stripe. Your card details go to Stripe, not to us — we never see or store them. Prices include any tax we are required to charge; where you are responsible for local taxes or duties, they are yours to pay.

You are buying a digital item that is produced on demand, and generation starts as soon as you pay. By buying, you ask us to start immediately and accept that once a case has been generated it cannot be cancelled for a refund. This does not affect your statutory rights as a consumer, or the failure refunds below.

Generation can fail. When a paid case fails permanently, we refund that payment in full, automatically, and email you — you never end up paying for a case you did not get. Refunds typically appear on a statement within 5 to 10 business days.

Retrying is a new case: it is charged like any other, and refunded the same way if it also fails. A teaching note that fails to generate is refunded on the same basis.

If something has gone wrong and you have not been refunded, tell us with the feedback button on any page or email hello@caselens.cc, and we will sort it out.

Annotation — highlighting and margin notes on a case — is an optional add-on and is still in testing. Notes are saved against the browser they were written in, because students do not have accounts. Clearing cookies, switching device, or using private browsing means the notes will not be there.

So please treat annotation as a classroom convenience, not a record: it comes with one-click Markdown export, and we encourage students to export regularly. We do not guarantee that annotations will persist, and we are not liable for notes that are lost.

When using CaseLens, you agree not to:

• break the law, infringe anyone's rights, or generate material that is defamatory, harassing, or otherwise unlawful about a company or a person;
• share a case beyond the seats you have licensed, or work around any licence, payment, or access control;
• generate cases in bulk, automate access, scrape the site, or circumvent rate limits or capacity controls;
• reverse engineer the service, or use it to build a competing case-generation product;
• probe or attack the service's security, or try to reach accounts, cases, teaching notes or notes that are not yours;
• misrepresent a generated case as human-authored scholarship, or strip out the citations and limitations that let a reader judge it; or
• resell or redistribute access to CaseLens itself.

CaseLens is in beta. Cases you create are real and yours to keep, but features may change, be added, or be withdrawn, and some — annotation among them — are explicitly in testing.

We aim to keep the service available and to keep published case links working, but we do not promise uninterrupted or error-free service. Generation takes time (usually around ten minutes) and runs under capacity limits, so we cannot promise a particular turnaround.

If we discontinue a feature or the service, we will give you what notice we reasonably can, and we will not charge you for cases we cannot deliver.

Cases cite and link to third-party sources, and the service runs on third-party AI, data, email, payment and hosting providers. We do not control third-party content, and a citation is not an endorsement of it. Following an external link takes you to a site with its own terms and privacy policy.

Our Privacy Policy explains what personal information we collect, who processes it, how long we keep it, and the rights you have over it. Please read it — it forms part of your agreement with us.

You can stop using CaseLens at any time and ask us to close your account and delete your data, as described in the Privacy Policy.

We may suspend or close an account, or take down a case, if these terms are breached, if payment fails or is reversed, if we are required to by law, or if use of the service threatens its security or other users. Where the reason is not urgent, we will tell you first and give you a chance to put it right. If we close your account without cause, we will refund anything you have paid for and not received.

A case already published and licensed to a class stays available where we can reasonably keep it so, because students may be relying on it mid-term. The licences you have already bought survive the closing of your account.

Except as these terms expressly say, and to the fullest extent the law allows, CaseLens is provided as is and as available, and we exclude all implied warranties — including that the service or any case will be accurate, complete, current, fit for a particular purpose, or uninterrupted.

Nothing in these terms excludes the statutory rights of a consumer, or any liability that cannot lawfully be excluded.

We do not exclude or limit our liability for death or personal injury caused by our negligence, for fraud or fraudulent misrepresentation, or for anything else that cannot lawfully be limited.

Subject to that, and to the fullest extent the law allows:

• we are not liable for teaching, academic, commercial or financial decisions taken in reliance on a generated case, or for the accuracy of the information in one;
• we are not liable for lost profits, lost revenue, lost teaching time, reputational harm, or lost or corrupted content or annotations; and
• our total liability arising from your use of CaseLens is limited to the greater of £100 and the total amount you paid us in the twelve months before the claim arose.

These limits apply to claims in contract, tort (including negligence), and otherwise, and reflect that CaseLens is a low-cost service producing AI-generated material you are asked to verify.

If you use CaseLens in breach of these terms — distributing cases beyond your licensed seats, for instance, or putting unlawful content into an input — you agree to cover the losses, claims and reasonable costs we incur as a result. This does not apply to anything caused by our own breach or negligence, and, if you are a consumer, does not extend beyond what you are responsible for in law.

We may update these terms as the service changes. The date at the top of this page shows when we last did. For changes that materially affect you, we will give reasonable notice — by email or on the site — before they take effect, and continuing to use CaseLens afterwards means you accept them. The terms in force when you make a purchase govern that purchase.

These terms and any dispute arising from them are governed by the laws of England and Wales, and the courts of England and Wales have exclusive jurisdiction. If you are a consumer resident elsewhere, you keep the protection of your local mandatory consumer law and may bring proceedings in your own courts.

Please raise a problem with us first. Most things are quicker to fix directly than formally, and we would rather fix them.

Use the feedback button in the bottom-right corner of any page, or email us at hello@caselens.cc. Feedback goes straight to the person who built CaseLens, and we come back to you.
