Cascade.

Terms and conditions

Last updated 8 October 2026

1. Who you are contracting with

Cascade is operated by Lamaryalia Shenwary, a sole trader based in the United Kingdom, trading as Cascade, trading in England. A postal address for correspondence is available on request. Contact: support@cascade.clinic.

Using Cascade means you accept these terms. If you do not, do not use it.

2. What Cascade is, and what it is not

Cascade is an educational tool for UKMLA revision. It simulates physiology so you can see how one intervention moves a whole system, and it sets out UK guideline material alongside each condition with its source named.

It is not medical advice and it is not a clinical decision tool. The simulations are teaching models: deliberate simplifications of human physiology, tuned to make a mechanism visible rather than to predict what any real patient will do. Nothing here should be used to make a decision about a real person.

Guideline content is cross-referenced against published UK sources at the time it is written. Guidance changes. Always check the current primary source, NICE, BNF, BTS/SIGN, UKKA or whichever body applies, before relying on anything in practice. You remain responsible for your own clinical judgement and for meeting the standards of your regulator and your medical school.

Cascade is not affiliated with, endorsed by, or connected to the GMC, the Medical Schools Council, NICE, or any medical school. UKMLA is referred to only to describe what the material covers.

No promise is made about your exam result. Passing an exam depends on you.

3. Your account

• Give a real email address you can access. It is how a password reset reaches you, and losing access to it can mean losing access to your account.
• Keep your password to yourself. You are responsible for what happens under your account.
• One account per person, and one person per account. Sharing your account with somebody else is a breach of these terms and is grounds for suspension.
• Tell us promptly if you think someone else has got into your account.

4. Pricing and access

Read this section carefully, because it is the one people most often assume they know.

• £30 for 365 days of everything. It is a one-off payment. It is never auto-renewed, and no card is kept on file for a free year.
• The first 100 accounts to sign in after launch with a confirmed email address get 365 days free. You get this once per person, ever. A place is given when you sign in, not when you sign up, so an account whose email address is not yet confirmed does not hold one. A place is not handed on if an account is later deleted.
• Accounts that existed before launch get 365 days from launch day. That year is separate from the first 100.
• When a year ends, your account returns to the free tier and keeps its history. Your progress and scores stay. We will show a notice in your account from 30 days before it ends, and nothing is charged unless you choose to pay.
• Free forever: the daily case and the school leaderboard, with no account. With a free account, every playground with its free conditions and the guideline panel.
• Paying early adds 365 days on top of what is left of your current year, so you lose nothing by paying before it ends.
• What is included may grow, new body systems, new cases, and no specific future feature is promised or guaranteed.

Refunds.

• Changed your mind? You have 14 days. Email support@cascade.clinic within 14 days of paying and you get the full £30 back. No reason needed, even if you have used Cascade in that time. Your paid access ends when the refund is made.
• After 14 days there is no refund for time you have not used, with two exceptions. If Cascade is discontinued, or a substantial part of what you paid for is permanently removed, you get a refund for the whole months left on your paid year. And if Cascade is faulty or not as described, you keep your rights under the Consumer Rights Act 2015. Nothing in these terms takes away your legal rights.
• If you paid early, on top of a year you already had, a refund removes the 365 days that payment added. Any free year you already had is untouched.
• Payments are processed by Stripe and sold through Link, Stripe's checkout service. Your receipt comes from Link, and you can also ask Link support for a refund. A refund made by Link counts as a refund under these terms.
• A free year costs nothing, so there is nothing to refund.

5. Acceptable use

You may use Cascade for your own study. You may not:

• share, sell, sublicense or publish account credentials or Cascade's content;
• scrape, bulk-download, mirror or systematically extract the cases, question bank, guideline text or simulation code;
• copy the content into another product, a revision resource, a study group pack or a commercial course;
• attempt to bypass the rate limits or any access control;
• automate play, script the daily case, or otherwise manipulate a leaderboard;
• probe, attack, overload or interfere with the service or its infrastructure;
• submit anything unlawful, abusive or deliberately false through the report box, or use a display name that is offensive or impersonates somebody else.

Access may be suspended or ended for a serious or repeated breach, including sharing an account, scraping, or cheating.

Good-faith security research is welcome. Report anything you find to support@cascade.clinic before disclosing it, do not access anybody else's data, and do not degrade the service for other people. Do that and no action will be taken against you.

6. Leaderboards

Leaderboards are optional and off until you turn them on. Section 7 of the privacy policy sets out exactly what becomes visible.

Rankings are based on how many people turned up and played, not on scores, precisely so there is nothing to be gained by inflating a score. Entries, display names or accounts may be removed from a leaderboard where there is evidence of manipulation, and that judgement is Cascade's to make.

7. Content accuracy

Considerable effort goes into clinical accuracy, and every condition, drug note and Qbank rationale carries a report button for exactly this reason. Reports are read and acted on.

Errors will still exist. Cascade is provided as a study aid and no warranty is given that it is complete, current or free from mistakes. If you spot something wrong, report it, that is the fastest route to it being fixed for everyone.

8. Intellectual property

The simulations, cases, question bank, written explanations, design and code are owned by Cascade or used under licence. You get a personal, non-transferable, non-exclusive right to use them for your own study for as long as your access lasts. Nothing more is granted.

Guideline content is summarised from, and attributed to, its publishers. Those publishers retain their own rights in their material.

Anything you submit through the report box may be used to correct and improve Cascade, without payment and without attribution to you.

9. Availability

Cascade is a beta product run by one person. No uptime guarantee is given. Maintenance, outages, provider failures and breaking changes all happen, and access may be interrupted without notice.

Features may be added, changed or withdrawn. If something material to what you have paid for is withdrawn permanently, you will be given notice on the site and in your account.

10. Liability

Nothing in these terms limits liability for death or personal injury caused by negligence, for fraud or fraudulent misrepresentation, or for anything else that cannot lawfully be limited. Your statutory rights as a consumer are not affected.

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

• Cascade is not liable for any clinical decision, exam outcome, academic result or professional consequence arising from using it. It is a study aid, and section 2 says plainly what it is not;
• Cascade is not liable for loss of data, loss of study time, or losses that were not reasonably foreseeable when you bought;
• total liability for any claim connected with these terms is limited to the amount you have paid to Cascade in the twelve months before the claim.

Cascade is supplied for personal study. If you use it for business purposes, the consumer protections above do not apply to you.

11. Ending the agreement

You can stop using Cascade and delete your account at any time. Deleting your account removes your progress permanently; there is no undo.

Access may be ended for a serious breach of section 5, or if Cascade is discontinued. If Cascade is discontinued, notice will be given on the site and in your account.

12. Changes to these terms

These terms may change. The date at the top is the version in force. Material changes will be notified on the site and in your account before taking effect, and if you do not accept them you may end your access and delete your account at any time.

13. Law and disputes

These terms are governed by the law of England and Wales, and its courts have jurisdiction. If you live in another part of the UK you keep the right to bring proceedings in your own.

Please raise a complaint with support@cascade.clinic first. Most things are fixable without lawyers.
