Terms of Use

Effective date: 1 October 2026
Last updated: 11 October 2026

These Terms of Use ("Terms") are a binding agreement between you and Uroš Rajčić, a natural person (not a registered company), of Nemanjina 61, 12000 Požarevac, Serbia, publishing the App under the BeerCounter developer account ("ClinQuiz", "we", "us", "our"). They govern your access to and use of the ClinQuiz: Medical Case Quiz mobile application, its home-screen widget, the website at clin-quiz.com, and every related feature, content and service (together, the "App").

PLEASE READ THESE TERMS CAREFULLY. SECTION 2 (NOT MEDICAL ADVICE), SECTION 3 (NO GUARANTEE OF ACCURACY), SECTION 13 (DISCLAIMER OF WARRANTIES), SECTION 14 (LIMITATION OF LIABILITY) AND SECTION 15 (INDEMNITY) LIMIT OUR RESPONSIBILITY TO YOU. BY CREATING AN ACCOUNT, OR BY DOWNLOADING, OPENING OR USING THE APP, YOU CONFIRM THAT YOU HAVE READ, UNDERSTOOD AND ACCEPTED THESE TERMS AND OUR PRIVACY POLICY. IF YOU DO NOT AGREE, DO NOT USE THE APP.

1. What the App is

1.1. ClinQuiz is a game: an educational-entertainment quiz in which you read simulated ("fictional") clinical scenarios, "buy" investigations with in-game points, and try to guess a diagnosis. Scores, points, streaks, leaderboards, ranks, ranked duels, ratings and statistics are game mechanics only.

1.2. All cases are simulated. Patients, histories, findings, images, laboratory values, scenarios and outcomes are invented or adapted for the purpose of the game. Any resemblance to a real person, living or dead, or to a real clinical event is coincidental.

1.3. The App is intended as a light, supplementary study and entertainment tool for adults, primarily medical students and healthcare professionals. It is not a medical device, a clinical decision-support tool, a diagnostic tool, an accredited course, a continuing medical education (CME/CPD) activity, an exam-preparation product with any guaranteed result, or a substitute for textbooks, clinical guidelines, supervision or professional training.

2. NOT MEDICAL ADVICE

2.1. Nothing in the App is medical advice, a diagnosis, a treatment recommendation, or a professional opinion of any kind. All content, including case text, diagnoses, "correct answers", explanations, teaching breakdowns, management and treatment descriptions, drug names, doses, reference ranges, ICD codes and any other information (together, "Content"), is provided for general informational, educational and entertainment purposes only.

2.2. Do not use the App, or anything you learned from it, to diagnose, treat, manage, triage or make any decision about any real patient, including yourself, your family or anyone else. Clinical decisions must always be based on your own professional judgement, current official clinical guidelines, the product information of any medicine, the rules of your institution, and appropriate supervision.

2.3. Using the App does not create a doctor–patient, therapist–patient or any other healthcare-professional relationship between you and us, our authors, reviewers, contributors or anyone else.

2.4. If you have, or think you may have, a medical problem, contact a qualified healthcare provider. In an emergency, call your local emergency number (for example 112 in Europe/Serbia or 911 in the US) immediately. Never disregard professional medical advice or delay seeking it because of something you saw in the App.

2.5. You use the Content entirely at your own risk. You are solely responsible for any use you make of it.

3. NO GUARANTEE OF ACCURACY

3.1. Medicine changes constantly, and practice differs between countries and institutions. We do not warrant, represent or guarantee that any Content is accurate, complete, correct, current, reliable, consistent with any guideline or curriculum, or suitable for any purpose. Content may contain errors, omissions, simplifications, outdated information, typos, wrong values, wrong units or wrong answers. Several diagnoses may be plausible for the same case, and the answer the App accepts as "correct" may be incomplete or wrong.

3.2. Some Content, including translations into languages other than English, may be created, adapted or translated with the help of automated tools, including artificial-intelligence systems, and may not have been reviewed by a medical professional. Translations may differ from the English original; if they conflict, neither version is guaranteed to be correct.

3.3. The way the App judges your answer (for example spelling tolerance, synonyms and accepted aliases) is automated and may reject a correct answer or accept a wrong one. A score, a rank, a streak or a "correct" result says nothing about your real clinical knowledge or competence and is not a qualification, certificate, grade or evidence of skill. You may not present it as such.

3.4. We may, but are not obliged to, correct, change, re-score or remove any Content at any time without notice. We are not obliged to re-calculate or restore scores, points or leaderboard positions affected by an error.

3.5. You can report a suspected error through the in-app feedback. Reporting does not oblige us to respond or make any change.

4. Eligibility and accounts

4.1. You must be at least 18 years old to use the App, create an account or make any purchase. The App is not directed to children.

4.2. You may create an account with an email address and password, or with Sign in with Apple or Google Sign-In. You must give accurate information and keep it up to date. You are responsible for keeping your credentials confidential and for all activity under your account. Tell us immediately at support@clin-quiz.com if you suspect unauthorised use.

4.3. One person, one account. Accounts are personal and may not be sold, transferred, shared or rented.

4.4. You may delete your account at any time in Profile → Delete account. Deletion is permanent and cannot be undone; your progress, points, streaks, colleagues and unused in-game benefits, including specialty packs you bought, are lost (see Section 8.7). Deleting your account does not cancel a store subscription — see Section 8.

5. Your conduct

You agree not to:

a) use the App for any clinical, diagnostic, therapeutic or other real-world medical purpose;
b) choose a display name, or submit a comment or other material, that is unlawful, offensive, hateful, harassing, sexual, defamatory, misleading, impersonates any person or organisation (including falsely claiming a professional title), infringes anyone's rights, or contains personal or health data about any real person, including patients;
c) harass, spam or abuse other users, including through colleague requests or duel challenges;
d) cheat, manipulate scores or leaderboards, exploit bugs, use automated means (bots, scripts, scrapers), or create multiple accounts;
e) copy, scrape, download in bulk, republish, sell or otherwise extract the Content or any database of the App, or use it to train or feed any artificial-intelligence or machine-learning model;
f) reverse engineer, decompile, disassemble, or attempt to derive the source code of the App, except where the law expressly permits this despite this restriction;
g) interfere with, overload, probe, scan or test the vulnerability of the App or its servers, or bypass any security, access control, paywall or usage limit;
h) use the App in breach of any applicable law or of the terms of the Apple App Store or Google Play.

We may, at our sole discretion and without prior notice, remove or change any display name or submitted material, reset scores, remove you from leaderboards, and suspend or terminate your account if we believe you have breached these Terms, or to protect the App, other users or us.

6. Material you submit

6.1. When you rate a case, write a comment or feedback, or otherwise submit material ("Submissions"), you confirm that you have the right to do so and that it contains no personal or health data about any real person.

6.2. You grant us a worldwide, perpetual, irrevocable, royalty-free, transferable and sub-licensable licence to use, copy, modify, translate, publish and otherwise exploit your Submissions for operating, improving and promoting the App, without any obligation to credit or pay you. We may use feedback and suggestions freely. We have no obligation to store, publish or act on any Submission. This licence is subject to the Privacy Policy and your right to erasure: when you delete your account we delete the text of your feedback comments.

7. Social features and visibility

7.1. Your display name, avatar, country and game statistics (points, rank, streaks, solved cases and similar) are visible to other users in leaderboards, colleague lists, search and player profiles. Do not use your full real name as a display name if you do not want it to be public.

7.2. Other users are not our employees or agents. We do not verify their identity, profession or qualifications and are not responsible for their conduct.

7.3. If you share a result card or link outside the App, you do so voluntarily and at your own risk; the recipient platform's own terms apply.

7.4. Ranked duels. When no other player is available at your level, you may be matched with a recorded run of another player's earlier duel (a "ghost") or with an AI practice opponent. Ghost and AI opponents play under the same rules and scoring as live players, and results against them count toward your rating. We do not indicate which opponents are live. Your own duel runs may be replayed to other players as ghosts under your display name, avatar, country and rank; you can turn this off at any time in Profile → Ranked duels. A replay shows how you progressed through each case and your result, never the diagnoses you typed.

7.5. Fair play in duels. During a live duel, keep the App open on the match. Leaving it for more than a few seconds (for example switching to another app or locking your phone), losing the connection for a similar time, or leaving the match counts as a loss. If you repeatedly fail to confirm matches you were offered, matchmaking may be paused for a few minutes. If our automated checks flag unusual play, rating changes may be paused while we review it. Contact us if you think a result was recorded wrongly.

7.6. Friendly duels. You can challenge a colleague to a friendly duel. They are notified (by push notification if they have enabled it) and can accept or decline within two minutes. Friendly duels follow the same rules as ranked duels, but they do not change your rating, do not use your free daily duels and are never replayed as ghosts. To prevent spam, we may limit how often you can challenge the same colleague.

8. Purchases, subscriptions and in-game items

8.1. Some features or content (for example "Pro" access or specialty packs) may be offered for payment, as a one-time purchase or an auto-renewing subscription. When offered, "Pro" is sold as a monthly or annual subscription, specialty packs as one-time purchases, and a free plan may include a daily limit of cases and of ranked duels. We do not guarantee that a live opponent is available for a ranked duel at any given time (see 7.4). Prices, billing periods, content and features are shown in the App before you buy, are shown in your local currency, and include applicable taxes where the store adds them. They may change for future billing periods; where a price increase needs your consent, Apple or Google will ask for it, and if you do not consent the subscription ends at the end of the current period. We may also offer free periods, promotions or free-tier limits, and change or end them at any time.

8.2. All payments are processed by Apple (App Store) or Google (Google Play), not by us, under their terms. We never see your card details. Subscriptions renew automatically at the end of each period unless you cancel at least 24 hours before the period ends, in your store account settings (iOS: Settings → Apple ID → Subscriptions; Android: Google Play → Payments & subscriptions). Uninstalling the App or deleting your account does not cancel a subscription.

8.3. Refunds are handled by Apple or Google under their policies. Except where mandatory law requires otherwise, we do not grant refunds, credits or pro-rated amounts, including for partially used periods, unused content, Content you consider inaccurate, or accounts suspended or terminated for breach of these Terms. This does not affect the rights a consumer has by mandatory law if paid digital content or a digital service does not conform to what was agreed (for example repair, price reduction or termination).

8.4. Statutory right of withdrawal (EU/EEA, Serbia and similar laws): when you buy digital content or a digital service that is supplied immediately, you expressly request immediate supply and acknowledge that you lose your right of withdrawal once supply has begun, to the extent the law permits.

8.5. Points, scores, streaks, ranks, ratings, "gifts", free cases and other in-game items have no monetary value, are not your property, cannot be exchanged for money or transferred, and may be changed, reset or removed by us at any time without compensation.

8.6. Paid access gives you access to the App as it exists from time to time. We do not guarantee any particular number of cases, update frequency, feature or availability of any specific content.

8.7. Your purchases and your account. Paid access is linked to your ClinQuiz account and to the Apple or Google account used to buy it. A subscription bought in one store does not carry over to the other store. If you reinstall the App or sign in on a new device, use "Restore purchases" in the App. If you delete your ClinQuiz account, you lose the paid access and packs linked to it, and we cannot restore them.

8.8. Refunds and reversed payments. If Apple or Google refunds or reverses a payment, we may withdraw the access it paid for.

9. Intellectual property

9.1. The App, the Content, cases, texts, images, design, logo, the name "ClinQuiz", software and databases are owned by us or our licensors and are protected by copyright, database, trademark and other laws. All rights not expressly granted are reserved.

9.2. We grant you a personal, limited, revocable, non-exclusive, non-transferable, non-sublicensable licence to install and use the App on devices you own or control, for your personal, non-commercial use, in accordance with these Terms and the rules of the store you downloaded it from. You may not use the Content for commercial teaching, publications, question banks, courses or other products.

10. Third-party services

The App relies on third parties (for example Apple, Google, RevenueCat, Expo, hosting and email providers — see the Privacy Policy). Their services are governed by their own terms, and we are not responsible for their availability, acts or omissions. Links to external websites are provided for convenience only; we do not endorse or control them.

11. Availability, changes and beta features

11.1. The App is provided on an "as available" basis. We do not guarantee that it will be uninterrupted, secure, timely, error-free or free of viruses, or that your data, progress or scores will never be lost. It may require an internet connection and a recent operating-system version, and we may require you to update the App to continue using it.

11.2. We may change, add, remove, suspend or discontinue any part of the App, any feature or any Content, temporarily or permanently, at any time, with or without notice, and without liability to you. Features marked as beta, preview or test are provided without any commitment.

12. Suspension and termination

12.1. You may stop using the App at any time.

12.2. We may suspend or terminate your access or account at any time, with or without notice, if you breach these Terms, if required by law, to protect other users, or if we discontinue the App. Where you paid for a subscription and we discontinue the App for reasons unrelated to your conduct, your only remedy is any refund that mandatory law or the relevant store's policy provides.

12.3. Sections 2, 3, 6, 8.5, 9, 13–19 survive termination.

13. DISCLAIMER OF WARRANTIES

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE APP AND ALL CONTENT ARE PROVIDED "AS IS" AND "AS AVAILABLE", WITH ALL FAULTS AND WITHOUT WARRANTY OF ANY KIND. WE, OUR OWNERS, DIRECTORS, EMPLOYEES, CONTRACTORS, AUTHORS, CONTENT REVIEWERS, LICENSORS AND SUPPLIERS (THE "CLINQUIZ PARTIES") EXPRESSLY DISCLAIM ALL WARRANTIES, WHETHER EXPRESS, IMPLIED, STATUTORY OR OTHERWISE, INCLUDING ANY WARRANTY OF ACCURACY, COMPLETENESS, CURRENCY, RELIABILITY, MERCHANTABILITY, SATISFACTORY QUALITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, NON-INFRINGEMENT, AND ANY WARRANTY ARISING FROM COURSE OF DEALING OR USAGE. NO ADVICE OR INFORMATION, WHETHER ORAL OR WRITTEN, OBTAINED FROM US OR THROUGH THE APP CREATES ANY WARRANTY NOT EXPRESSLY STATED IN THESE TERMS.

If you are a consumer, this Section does not limit your statutory rights if paid digital content or a digital service does not conform to what was agreed.

14. LIMITATION OF LIABILITY

14.1. TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE CLINQUIZ PARTIES SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUE, DATA, PROGRESS, GOODWILL, OPPORTUNITY, EXAM RESULTS, ACADEMIC OR PROFESSIONAL STANDING, OR FOR ANY PERSONAL INJURY, ILLNESS, DEATH OR HARM TO ANY PERSON OR PATIENT, ARISING OUT OF OR IN CONNECTION WITH THE APP, THE CONTENT, ANY ERROR OR INACCURACY IN IT, ANY DECISION OR ACTION TAKEN IN RELIANCE ON IT, THE CONDUCT OF OTHER USERS, OR THESE TERMS, WHETHER BASED ON CONTRACT, TORT (INCLUDING NEGLIGENCE), STRICT LIABILITY OR ANY OTHER THEORY, EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

14.2. TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE TOTAL AGGREGATE LIABILITY OF THE CLINQUIZ PARTIES FOR ALL CLAIMS ARISING OUT OF OR RELATING TO THE APP OR THESE TERMS SHALL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU ACTUALLY PAID FOR THE APP IN THE TWELVE (12) MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM, AND (B) FIFTY EUROS (EUR 50).

14.3. Nothing in these Terms excludes or limits liability that cannot be excluded or limited under applicable law, such as liability for any damage caused intentionally or by gross negligence, for fraud, for death or personal injury, or your mandatory statutory rights as a consumer (including those for non-conforming digital content). In jurisdictions that do not allow certain exclusions or limitations, our liability is limited to the smallest extent the law permits.

15. Indemnity

If you use the App other than as a consumer, or in breach of Section 2 or 5, and to the extent permitted by law, you agree to defend, indemnify and hold harmless the ClinQuiz Parties from and against any claims, liabilities, damages, losses, costs and expenses (including reasonable legal fees) arising out of or related to: (a) your use or misuse of the App or the Content, including any use for real patient care; (b) your Submissions or display name; (c) your breach of these Terms or of any law; or (d) your violation of any right of a third party. A consumer is liable to us only to the extent the law provides.

16. Changes to these Terms

We may update these Terms. If a change is material, we will notify you in the App or by email at least 30 days before it takes effect (or sooner where a law or an urgent security need requires). If you do not agree, you can stop using the App and delete your account before the change takes effect; if you keep using the App afterwards, the updated Terms apply to you. A change does not affect a purchase you have already made for the period you have paid for.

17. Governing law and disputes

17.1. These Terms, and any dispute or claim arising out of or in connection with them or the App, are governed by the laws of the Republic of Serbia, excluding its conflict-of-law rules and the UN Convention on Contracts for the International Sale of Goods.

17.2. The courts with jurisdiction in Požarevac, Serbia have exclusive jurisdiction, except that if you are a consumer habitually resident in the EU/EEA or another country whose mandatory law gives you the right to sue or be sued in your home courts or to rely on the protection of your local law, you keep that right. If you are a consumer in Serbia, you may also bring a claim in the court competent for your place of residence.

17.3. We encourage you to contact us first at support@clin-quiz.com; we will try in good faith to resolve the matter informally within 30 days. This does not limit your right to go to court or to a consumer-dispute body at any time. EU consumers may also use the EU's online dispute resolution information at https://consumer-redress.ec.europa.eu/ (we are not obliged to participate in alternative dispute resolution unless the law requires it).

18. Apple App Store and Google Play

18.1. If you downloaded the App from the Apple App Store, you and we acknowledge that: (a) these Terms are concluded between you and us only, not with Apple Inc. ("Apple"), and we, not Apple, are solely responsible for the App and its content; (b) your licence is limited to use on Apple-branded products that you own or control, as permitted by the Usage Rules in the Apple Media Services Terms and Conditions, except that the App may be accessed by other accounts associated with you via Family Sharing where applicable; (c) Apple has no obligation to provide any maintenance or support for the App; (d) in the event of any failure of the App to conform to any applicable warranty, you may notify Apple and Apple will refund the purchase price (if any) for the App to you, and to the maximum extent permitted by law Apple has no other warranty obligation with respect to the App; (e) we, not Apple, are responsible for addressing any claims by you or a third party relating to the App or your possession or use of it, including product-liability claims, claims that the App fails to conform to any legal or regulatory requirement, and claims under consumer-protection, privacy or similar legislation; (f) in the event of any third-party claim that the App or your possession and use of it infringes that third party's intellectual-property rights, we, not Apple, are solely responsible for the investigation, defence, settlement and discharge of that claim; (g) you represent and warrant that you are not located in a country subject to a U.S. Government embargo or designated as "terrorist supporting", and you are not listed on any U.S. Government list of prohibited or restricted parties; (h) you must comply with applicable third-party terms of agreement when using the App; and (i) Apple and its subsidiaries are third-party beneficiaries of these Terms and, upon your acceptance, Apple will have the right (and will be deemed to have accepted the right) to enforce these Terms against you as a third-party beneficiary.

18.2. If you downloaded the App from Google Play, the Google Play Terms of Service also apply to your download and purchases. Google is not a party to these Terms and is not responsible for the App.

19. General

19.1. Entire agreement. These Terms and the Privacy Policy are the entire agreement between you and us regarding the App and supersede any prior agreements.

19.2. Severability. If any provision is held invalid or unenforceable, it will be enforced to the maximum extent permitted and the remaining provisions remain in full force.

19.3. No waiver. Our failure to enforce any right is not a waiver of it.

19.4. Assignment. You may not assign or transfer these Terms. We may assign or transfer them, in whole or in part, including in connection with a merger, acquisition or sale of assets.

19.5. Force majeure. We are not liable for any delay or failure caused by events beyond our reasonable control.

19.6. Language. These Terms may be provided in several languages. If there is any conflict, the English version prevails, except that if you are a consumer in Serbia, the Serbian version prevails, and except where other mandatory law requires otherwise.

19.7. Contact. Uroš Rajčić, Nemanjina 61, 12000 Požarevac, Serbia, email: support@clin-quiz.com.
