Terms of Service

1. Eligibility and account

• You must be at least 16 years old. If you are under the age of majority where you live, a parent or guardian must agree to these Terms for you.
• You must give accurate information, keep your password secret, and use one account that only you use.
• You are responsible for everything done through your account. Tell us at once at kalangedavies@gmail.com if you suspect unauthorised use.

2. The service

Yanga generates practice questions, flashcards, study plans, and performance analyses from study material you provide and from general medical topics; schedules reviews with spaced repetition; and offers optional community sharing, classmate following, and direct messaging. Features, quotas, and prices may change. We may add, alter, or withdraw features at any time, and we will give reasonable notice of changes that materially reduce a paid plan.

3. Your content and copyright

• You keep ownership of everything you upload or write ("Your Content"). You grant us a worldwide, non-exclusive, royalty-free licence to store, process, display, and transmit Your Content to our service providers solely to operate the service for you, including sending it to AI providers to generate the output you request. The licence ends when the content is deleted, except for copies in routine backups that expire on their own schedule.
• Upload only what you have the right to upload. Your own notes and lecture summaries are always fine. Do not upload textbooks, commercial question banks, publisher slides, or other copyrighted material unless you hold the rights or a licence that permits this use. You are solely responsible for Your Content and you will indemnify us for claims arising from it (Section 13).
• Copyright complaints. If you believe content on Yanga infringes your copyright, send a notice to kalangedavies@gmail.com identifying the work, the infringing material and its location, your contact details, a statement of good-faith belief, a statement under penalty of perjury that you are authorised to act, and your physical or electronic signature. We remove infringing material promptly and terminate repeat infringers.
• Generated content (questions, explanations, flashcards, analyses) created for you may be used for your personal study, including printing or exporting it. You may not resell it, publish it as a question bank, or use it to train competing models.

4. AI-generated content

Content is produced by large language models. It can contain errors, outdated guidance, or fabricated references, and it may not match your school's curriculum or the current edition of any examination. You are responsible for verifying it against authoritative sources. We provide a report button on every question and review reported items, but we do not guarantee that any item is correct.

5. Acceptable use

You agree not to:

• use the service for anything other than your own education;
• use it during, or to gain an unfair advantage in, any proctored examination;
• share, sell, or lend your account, or circumvent quotas or billing;
• scrape, crawl, bulk-download, or reverse-engineer the service or its content;
• upload malware, or content that is unlawful, infringing, harassing, hateful, sexually explicit, or that contains real patients' identifiable health information;
• impersonate anyone, or send unsolicited messages to other students;
• interfere with the service's security or other users' use of it.

6. Community and messaging conduct

Sharing to the community, following classmates, and direct messaging are optional. Be respectful. We may remove shared content and suspend or terminate accounts that violate Section 5, and we may do so without notice where necessary to protect other users. Direct messages are end-to-end encrypted, so we cannot read them; we act on reports and on the metadata we can see. Report abuse to kalangedavies@gmail.com. Blocking a user stops all contact from them.

7. Plans and billing

• Free plan: every new account starts here. Limited daily uses of each AI feature, as shown in the app. No card is required.
• Pro: $3 per month or $30 per year, billed in advance through Stripe. Subscriptions renew automatically at the end of each period until you cancel.
• Cancel anytime from Settings → Manage billing. Cancellation takes effect at the end of the period you have paid for; you keep Pro until then and keep all your content afterwards.
• Refunds are governed by our Refund Policy.
• Price changes take effect at your next renewal after at least 30 days' notice by email or in the app. If you do not agree, cancel before the renewal.
• Prices exclude any sales tax or VAT that Stripe is required to collect for your location.
• Deleting your account cancels any active subscription at the end of its current period.

8. Intellectual property

The Yanga Med QBank software, design, branding, question-writing methods, and all content we create are ours or our licensors'. Except for the personal-study rights in Section 3, no rights are granted to you. Feedback you send us may be used freely without obligation.

9. Third-party services

Payments are processed by Stripe under its own terms and privacy policy. AI output is generated by Anthropic and Google models. Other providers are listed in our Privacy Policy. We are not responsible for third-party services' availability or terms.

10. Termination

You may delete your account at any time from Settings; deletion becomes irreversible after a 48-hour grace period. We may suspend or terminate your account for breach of these Terms, for legal reasons, or if we discontinue the service, and we will refund any prepaid period we do not provide except where termination is for your breach. Sections 3 (licence to content already processed), 4, 11, 12, 13, and 14 survive termination.

11. Disclaimers

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE". TO THE FULLEST EXTENT PERMITTED BY LAW WE DISCLAIM ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, ACCURACY, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT CONTENT IS CORRECT, THAT THE SERVICE WILL BE UNINTERRUPTED OR ERROR-FREE, OR THAT USING IT WILL IMPROVE ANY EXAMINATION RESULT. NOTHING IN THE SERVICE IS MEDICAL ADVICE.

12. Limitation of liability

TO THE FULLEST EXTENT PERMITTED BY LAW, YANGA AND ITS OPERATOR, CONTRIBUTORS, AND PROVIDERS WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, DATA, OR GOODWILL, ARISING FROM OR RELATED TO THE SERVICE, INCLUDING RELIANCE ON AI-GENERATED CONTENT, EXAMINATION OUTCOMES, CLINICAL DECISIONS, OR SERVICE INTERRUPTIONS. OUR TOTAL LIABILITY FOR ALL CLAIMS IN ANY TWELVE-MONTH PERIOD IS LIMITED TO THE GREATER OF THE AMOUNT YOU PAID US IN THAT PERIOD OR FIFTY US DOLLARS (US$50). Some jurisdictions do not allow certain limitations; in those places our liability is limited to the extent the law permits. Nothing here limits liability that cannot be limited by law, including for death or personal injury caused by negligence, or for fraud.

13. Indemnification

You will defend and indemnify Yanga and its operator against claims, damages, and reasonable legal costs arising from Your Content, your breach of these Terms, or your violation of any law or third-party right.

14. Governing law and disputes

These Terms are governed by the laws of the United States and of the state in which the operator of Yanga Med QBank is domiciled, without regard to conflict-of-law rules. Before filing any claim, you agree to email kalangedavies@gmail.com describing the problem and to work with us in good faith for 30 days to resolve it. Claims that cannot be resolved informally must be brought in the courts of the operator's domicile, and you consent to their jurisdiction, except that either party may seek injunctive relief anywhere and consumers in the EU or UK may also bring claims in their home courts. Any claim must be filed within one year of the event giving rise to it, where the law allows.

15. Changes to these Terms

We may update these Terms. We will post the new version here, update the date above, and for material changes give you at least 14 days' notice in the app or by email. Continued use after the effective date is acceptance. If you do not agree, stop using the service and delete your account.

16. General

These Terms, the Privacy Policy, the Cookie Policy, and the Refund Policy are the entire agreement between us. If any provision is unenforceable, the rest remains in effect. Our failure to enforce a provision is not a waiver. You may not assign these Terms; we may assign them to a successor that operates the service. Questions: kalangedavies@gmail.com.
