Terms of Use

Willys Flashcard App, Exam Library and willysflashcards.com · Effective Date: June 18, 2026 · Last Updated: October 25, 2026

These Terms of Use (“Terms”) are an agreement between you and Coastal Dune Labs LLC, a Florida limited liability company (“Coastal Dune Labs,” “we,” “us,” or “our”). They govern your use of Willys Flashcard App (“Willys,” the “Application,” or the “App”), an iPhone, iPad, and Mac application we develop and publish; the ready-made study decks built into the App (the “Exam Library” or “Library Content,” defined in Section 4); and our website at willysflashcards.com (the “Website”), including its flashcard library pages. Together these are the “Services.”

By downloading, installing, or using the Application, by starting a subscription, or by using the Website, you agree to these Terms and to our Privacy Policy. If you do not agree, do not use the Services.

1. Eligibility

You must be old enough to hold your own Apple Account in your country (13 in the United States) to use the Application, and you must be old enough to form a binding contract under the law where you live, or be using the Services with the permission and supervision of a parent or legal guardian who agrees to these Terms on your behalf. Use of the Services is void where prohibited.

2. License to the Application

Subject to your compliance with these Terms and the Apple Licensed Application End User License Agreement (the “Apple Standard EULA”), we grant you a limited, non-exclusive, non-transferable, revocable license to download and use the Application for your personal, non-commercial use on any Apple-branded device that you own or control, as permitted by the App Store Usage Rules. All rights not expressly granted are reserved.

3. Your Content

Willys is a study tool. The flashcards, decks, text, images, audio recordings, imported documents, and other materials you create or import (“Your Content”) belong to you. Coastal Dune Labs does not access, collect, transmit, or store Your Content on our servers — we operate no servers that receive it. You are solely responsible for Your Content, including ensuring you have the right to use any material (such as PDFs, images, or decks made by others) you import, and for maintaining your own backups in accordance with Section 10.

If you send us feedback, suggestions, bug reports, or corrections to Library Content (“Feedback”), you give us a perpetual, irrevocable, worldwide, royalty-free license to use, reproduce, modify, and distribute the Feedback for any purpose, including shipping it in a future version of the App or the Exam Library, without any obligation or compensation to you. Do not send us Feedback that you do not have the right to share.

4. The Exam Library

4.1 What it is

The Application includes an optional library of ready-made study decks for school courses, standardized tests, licensing exams, professional certifications, and language exams (the “Exam Library”; the decks, cards, outlines, diagrams, audio, and other material in it, including the free samples shown on the Website, are “Library Content”). Library Content is written by or for Coastal Dune Labs as independent study notes. It is not official exam material, has not been reviewed or approved by any exam owner, school, or licensing body, and is not affiliated with, sponsored by, or endorsed by any of them.

4.2 Your license to Library Content

Subject to these Terms, we grant you a limited, non-exclusive, non-transferable, non-sublicensable, revocable license to study Library Content within the Application, on devices you own or control, for your personal, non-commercial education. Library Content is licensed, not sold. Some Library Content (“Pro Content”) is available only with an active Willys Pro subscription (Section 7); when your subscription ends, your license to Pro Content ends and the App may remove it from your library, except for any free sample decks.

4.3 What you may not do with Library Content

Except as expressly permitted by these Terms, by a license notice on a specific deck, or by law that cannot be excluded by contract, you may not: (a) copy, export, extract, scrape, screen-capture in bulk, or otherwise reproduce Library Content outside the Application, or circumvent any feature of the Application that limits export, sharing, or backup of Library Content; (b) share, distribute, publish, post, upload, sell, rent, lend, sublicense, or otherwise make Library Content available to anyone else, including on other flashcard or study platforms, file-sharing services, marketplaces, forums, or social media; (c) use Library Content for any commercial purpose, including teaching for a fee, tutoring businesses, test-preparation services, or advertising; (d) use Library Content, in whole or in part, to train, fine-tune, evaluate, or prompt any machine-learning or artificial-intelligence model, or to build any dataset, index, or competing product; (e) remove, alter, or obscure any copyright, trademark, source, or license notice in Library Content; or (f) present Library Content as official material of any exam owner. Editing a card in your own library for your own study is permitted; the result remains Library Content under this Section.

4.4 Accuracy; no warranty for Library Content

Library Content is written with care and checked against the sources each deck lists, but it may contain errors or omissions, exam syllabi and the laws, rules, standards, dosages, figures, and facts they cover change over time, and no study aid can anticipate what appears on your exam. Library Content is provided for general educational purposes only. It is not medical, nursing, pharmaceutical, legal, financial, tax, investment, engineering, driving, safety, or other professional advice, and it is not a substitute for your course, your teacher, the exam owner’s own publications, or a qualified professional. You are responsible for verifying any Library Content you rely on, particularly for clinical, legal, financial, or safety-related decisions. We do not guarantee that Library Content is complete, current, or free of errors, or that studying it will lead to any grade, score, pass, license, or certification. Section 13 (Disclaimer of Warranties) and Section 14 (Limitation of Liability) apply to Library Content in full.

4.5 Third-party marks

Exam, course, and certification names (for example AP®, SAT®, MCAT®, NCLEX-RN®, CFA®, GRE®, MBE®, PMP®, CompTIA®, AWS, JLPT, HSK, TOPIK) are the trademarks or service marks of their respective owners. We use them only to describe what a deck prepares you for. None of those owners is affiliated with, sponsors, or endorses Willys, Coastal Dune Labs, or any Library Content, and each exam shelf in the App and each exam page on the Website carries the notice its owner asks for. These Terms grant you no right to use any trademark.

4.6 Open-licensed material in Library Content

Some Library Content incorporates or was checked against third-party material published under an open license (for example public-domain U.S. government works or Creative Commons material), identified in the deck’s sources or in the App’s attributions. Nothing in these Terms limits any rights the applicable open license grants you in that third-party material; to the extent of any conflict, the open license governs that material.

4.7 Changes, versions, and errors

We may add, correct, reorganize, re-version, or withdraw any Library Content at any time without notice, including when an exam’s outline changes or an error is reported. A corrected deck ships as a new version in a future update of the App; we do not promise to correct any particular item or to keep any deck available. If you find a mistake, please tell us through our contact page.

5. AI-Generated Content

5.1 Apple Intelligence Processing

Willys can generate flashcards from text and PDFs using Apple Intelligence. Depending on your device and operating system, generation runs on your device or on Apple’s Private Cloud Compute; either way the content you provide for generation, including PDF text and prompts, is handled only by Apple’s model and is not sent to Coastal Dune Labs or any other party. Apple Intelligence is governed by Apple’s own terms and privacy policy.

5.2 No Guarantee of Accuracy

AI-generated flashcards may be inaccurate, incomplete, or misleading. They are provided as a drafting convenience only. You are responsible for reviewing and verifying all generated content before relying on it. Do not rely on AI-generated cards as an authoritative source, particularly when studying for examinations, certifications, or professional, medical, legal, or financial purposes. Cards you generate are Your Content; you are responsible for ensuring the material you give the model is yours to use.

5.3 Availability

AI features depend on device hardware and operating-system support for Apple Intelligence and may be unavailable on some devices or require a model download.

6. Educational Tool — No Warranty of Outcomes; Academic Integrity

Willys is a study aid provided for general informational and educational purposes only. It is not professional, medical, legal, financial, or other expert advice. We do not guarantee any particular learning outcome, retention result, grade, exam pass, license, or certification, whether from Your Content, AI-generated content, or Library Content. You are responsible for the accuracy of the study material you create and for independently verifying any information you rely on.

You are responsible for complying with the rules of your school, employer, and exam provider. Do not use the Services during an exam or assessment where outside aids are not allowed, and do not use them to obtain, reproduce, or share live or confidential exam questions.

7. Subscriptions and Purchases

Willys Pro. Some features and Pro Content require a paid subscription (“Willys Pro”). The current price, billing period, and any free-trial offer are shown in the App before you subscribe. The features included in Willys Pro may change over time; we will not materially reduce what a current subscription includes without notice.

Billing through Apple. Subscriptions are purchased from and billed by Apple through your Apple Account, under Apple’s terms. We do not receive or store your payment details. Payment is charged to your Apple Account at confirmation of purchase, or at the end of any free trial unless you cancel at least 24 hours before the trial ends.

Automatic renewal. Subscriptions renew automatically for the same period at the then-current price unless you cancel at least 24 hours before the end of the current period. You can manage or cancel your subscription at any time in your device’s Settings under your Apple Account → Subscriptions. Deleting the App does not cancel a subscription. Cancellation takes effect at the end of the current billing period; you keep Pro access until then.

Price changes. We may change subscription prices. Apple will notify you before a price increase takes effect and, where required, ask you to agree to it; if you do not agree, your subscription will end at the close of the current period.

Refunds. Because Apple processes all payments, refund requests are handled by Apple under its refund policy, which you can access at reportaproblem.apple.com. Except where the law requires otherwise, we cannot issue refunds ourselves, and we do not offer refunds or credits for partial periods, unused time, downgrades, or Library Content you did not use.

Free features. We may offer parts of the Services for free, with limits that we may change at any time. We may also offer promotional pricing or trials to some users and not others.

8. Acceptable Use

You agree not to: (a) use the Services for any unlawful purpose or in violation of the rights of others; (b) infringe intellectual-property rights in material you import, generate, or share; (c) interfere with, disrupt, damage, overload, or impair the Services or any service they rely on; (d) circumvent any security, access-control, subscription, export-protection, or content-protection feature; (e) reverse engineer, decompile, or attempt to extract the source code, encryption keys, or bundled content of the Application, except to the extent applicable law expressly permits; (f) access the Website or its content by automated means (including crawlers, scrapers, or bulk-download tools) other than public search engines indexing pages we have not excluded, or extract Website content for datasets, AI training, or republication; (g) misrepresent your affiliation with Coastal Dune Labs or any exam owner, or use our name or marks without permission; or (h) use the Services to build, train, or improve a competing product.

9. Intellectual Property

The Application, the Library Content, the Website, and all associated content, design, text, graphics, audio, source code, trademarks, and other intellectual property are the property of Coastal Dune Labs and our licensors and are protected by copyright, trademark, and other laws. Facts and ideas are free for anyone to use; our selection, arrangement, and expression of them are not. Except for the limited licenses in Sections 2 and 4.2, no rights are transferred to you. You may not copy, modify, distribute, sell, lease, sublicense, or create derivative works of the Services except to the extent applicable law expressly prohibits such restriction. “Willys” and the Willys bear logo are trademarks of Coastal Dune Labs LLC.

10. Data Storage and Backups

Your Content is stored locally on your device. We do not maintain or operate any server that stores, mirrors, or backs up Your Content, and we cannot recover data stored on your device.

If you enable optional iCloud synchronization, Your Content is transmitted to and stored in your personal iCloud account, operated by Apple Inc. and governed by your agreement with Apple. We have no control over iCloud and are not responsible for any iCloud delay, conflict, partial sync, missed sync, corruption, deletion, or outage that affects Your Content.

The Application provides a backup export feature. We strongly recommend that you generate and save backups on a regular basis and store them in a location independent of your device. Storing exported backups securely is your sole responsibility and is your primary protection against data loss. Subject to Section 14, we are not liable for any loss of data, however caused.

11. Copyright Complaints

We respect the intellectual-property rights of others and expect the same of you. If you believe that Library Content or anything on the Website infringes a copyright you own or control, send us a notice through our contact page (choose “Something else”) that includes: (a) identification of the copyrighted work; (b) the deck name or Website URL of the material you believe infringes it; (c) your name, mailing address, and email address; (d) a statement that you have a good-faith belief that the use is not authorized by the copyright owner, its agent, or the law; (e) a statement, under penalty of perjury, that the information in your notice is accurate and that you are the owner or authorized to act for the owner; and (f) your physical or electronic signature. We will review every complete notice and remove or correct material where appropriate. Knowingly misrepresenting that material is infringing may expose you to liability under 17 U.S.C. § 512(f).

12. The Website

The Website describes the Application and lets you study free samples of Library Content in your browser on its flashcard library pages. You may study those samples as often as you like for your personal, non-commercial study; teachers may share links to the library pages with their students; and anyone may quote a card or two when discussing or reviewing the library, with a link back to the deck page. Otherwise the samples are Library Content like any other: Sections 4.3 and 8 apply to them, so do not copy them in bulk, republish them elsewhere (link to the deck page instead), or use them to train AI models. Website content may contain inaccuracies or typographical errors and may be changed or removed at any time. The Website may link to third-party sites and services (including the App Store); we do not control them and are not responsible for their content or practices. Messages you send through the contact form are handled as described in our Privacy Policy.

13. Disclaimer of Warranties

THE SERVICES, INCLUDING THE APPLICATION, THE LIBRARY CONTENT, AI-GENERATED CONTENT, AND THE WEBSITE, ARE PROVIDED “AS IS” AND “AS AVAILABLE,” WITH ALL FAULTS AND WITHOUT WARRANTY OF ANY KIND. TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, COASTAL DUNE LABS AND ITS LICENSORS DISCLAIM ALL WARRANTIES, EXPRESS, IMPLIED, OR STATUTORY, INCLUDING IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, ACCURACY, AND NON-INFRINGEMENT, AND ANY WARRANTIES ARISING FROM COURSE OF DEALING OR USAGE OF TRADE. WE DO NOT WARRANT THAT THE SERVICES WILL BE UNINTERRUPTED, TIMELY, SECURE, OR ERROR-FREE; THAT LIBRARY CONTENT OR AI-GENERATED CONTENT WILL BE ACCURATE, COMPLETE, CURRENT, OR SUITABLE FOR ANY PARTICULAR EXAM, COURSE, OR PURPOSE; THAT ANY DEFECT WILL BE CORRECTED; OR THAT YOUR DATA WILL BE PRESERVED OR RECOVERABLE. YOU USE THE SERVICES AT YOUR OWN RISK. NO ADVICE OR INFORMATION, WHETHER ORAL OR WRITTEN, OBTAINED FROM US OR THROUGH THE SERVICES CREATES ANY WARRANTY NOT EXPRESSLY STATED IN THESE TERMS. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OF IMPLIED WARRANTIES, SO SOME OF THE ABOVE MAY NOT APPLY TO YOU.

14. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT WILL COASTAL DUNE LABS, ITS MEMBERS, MANAGERS, EMPLOYEES, CONTRACTORS, OR LICENSORS BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUE, DATA, GOODWILL, OR USE, OR FOR ANY EXAM FAILURE, LOST TUITION OR EXAM FEES, LOST EMPLOYMENT OR LICENSURE, OR COST OF SUBSTITUTE MATERIALS, OR FOR ANY DAMAGES CAUSED BY THIRD-PARTY SERVICES YOU ACCESS THROUGH THE SERVICES (INCLUDING THE APP STORE, ICLOUD, AND APPLE INTELLIGENCE), ARISING OUT OF OR RELATING TO THESE TERMS OR THE SERVICES, WHETHER BASED ON WARRANTY, CONTRACT, TORT (INCLUDING NEGLIGENCE), STATUTE, OR ANY OTHER THEORY, AND EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, OUR TOTAL CUMULATIVE LIABILITY TO YOU FOR ALL CLAIMS ARISING OUT OF OR RELATING TO THESE TERMS OR THE SERVICES, TAKEN TOGETHER, WILL NOT EXCEED THE GREATER OF (A) THE TOTAL AMOUNT YOU ACTUALLY PAID FOR THE SERVICES (INCLUDING WILLYS PRO SUBSCRIPTION FEES PAID THROUGH APPLE), LESS ANY REFUNDS, IN THE TWELVE (12) MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM AND (B) TEN UNITED STATES DOLLARS (USD $10.00). IF YOU HAVE USED ONLY FREE FEATURES OF THE SERVICES, YOUR SOLE AND EXCLUSIVE REMEDY FOR ANY DISSATISFACTION WITH THE SERVICES, BEYOND THAT AMOUNT, IS TO STOP USING THEM. THE LIMITATIONS IN THIS SECTION ARE AN ESSENTIAL BASIS OF THE BARGAIN BETWEEN YOU AND US AND APPLY EVEN IF ANY LIMITED REMEDY FAILS OF ITS ESSENTIAL PURPOSE. SOME JURISDICTIONS DO NOT ALLOW CERTAIN EXCLUSIONS OR LIMITATIONS; IN THOSE JURISDICTIONS, OUR LIABILITY IS LIMITED TO THE MAXIMUM EXTENT PERMITTED BY LAW. NOTHING IN THESE TERMS EXCLUDES LIABILITY THAT CANNOT BE EXCLUDED BY LAW, INCLUDING FOR FRAUD OR FOR DEATH OR PERSONAL INJURY CAUSED BY NEGLIGENCE WHERE THE LAW SO PROVIDES.

15. Indemnification

To the extent permitted by law, you agree to defend, indemnify, and hold harmless Coastal Dune Labs and its members, managers, employees, contractors, and licensors from and against any claims, liabilities, damages, losses, and expenses, including reasonable attorneys’ fees, arising out of or related to (a) Your Content, including any claim that it infringes or misappropriates a third party’s rights; (b) your use or redistribution of Library Content in breach of Section 4; (c) your violation of these Terms or of any law; or (d) any dispute between you and a third party, including an exam owner, school, or employer, relating to your use of the Services. We may assume the exclusive defense and control of any matter subject to indemnification, in which case you agree to cooperate with us.

16. Apple App Store Provisions

These Terms are between you and Coastal Dune Labs only, not with Apple Inc. (“Apple”). Apple is not responsible for the Application or its content and has no obligation to provide maintenance or support services; any support we provide is described on our contact page. In the event of any failure of the Application to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price, if any; Apple has no other warranty obligation with respect to the Application, and any other claims, losses, liabilities, damages, costs, or expenses attributable to a failure to conform to a warranty are our responsibility, subject to these Terms. Apple is not responsible for addressing any claims by you or any third party relating to the Application or your use of it, including product-liability claims, claims that the Application fails to conform to any legal or regulatory requirement, consumer-protection or similar claims, and claims arising under Apple’s App Store Review Guidelines or similar rules; and if a third party claims that the Application or your use of it infringes that party’s intellectual-property rights, we, not Apple, are responsible for the investigation, defense, settlement, and discharge of that claim, subject to these Terms. You must comply with any applicable third-party terms when using the Application (for example, Apple’s terms for iCloud and Apple Intelligence). You represent that you are not located in a country subject to a U.S. Government embargo or designated as a “terrorist supporting” country, and that you are not on any U.S. Government list of prohibited or restricted parties. Apple and its subsidiaries are third-party beneficiaries of these Terms and, upon your acceptance, may enforce them against you. Your use of the Application must also comply with the App Store Usage Rules and the Apple Standard EULA, which is incorporated by reference; to the extent of any conflict, these Terms govern except where the Apple Standard EULA is more restrictive.

17. Termination

You may stop using the Services at any time; see Section 7 to cancel a subscription. We may suspend or terminate your access to the Services, or to any Library Content, at any time, with or without cause and with or without notice, including if we reasonably believe you have breached Section 4 or Section 8. Upon termination, your licenses under Sections 2 and 4.2 immediately cease; Your Content stays on your device and in your iCloud account. Sections 3, 4.3 through 4.6, 5.2, 6, 9, 11, and 13 through 20 survive termination, together with any other provision that by its nature should survive.

18. Dispute Resolution

Talk to us first. Most concerns can be resolved quickly and informally. Before starting any formal proceeding, you agree to send us a written description of the dispute and what you would like us to do through our contact page, and we agree to do the same to you at the email address associated with your message, and both of us agree to try in good faith to resolve the dispute for at least thirty (30) days after that notice.

Small claims. Either of us may bring an individual claim in a small-claims court of competent jurisdiction instead of the courts named in Section 19.

No class or representative actions; jury waiver. TO THE FULLEST EXTENT PERMITTED BY LAW, YOU AND COASTAL DUNE LABS AGREE THAT EACH MAY BRING CLAIMS AGAINST THE OTHER ONLY IN AN INDIVIDUAL CAPACITY AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY PURPORTED CLASS, COLLECTIVE, CONSOLIDATED, OR REPRESENTATIVE PROCEEDING, AND THAT EACH KNOWINGLY AND VOLUNTARILY WAIVES ANY RIGHT TO A TRIAL BY JURY. If this paragraph is found unenforceable as to a particular claim, it is severed as to that claim only.

Time limit. To the extent permitted by law, any claim arising out of or relating to these Terms or the Services must be filed within one (1) year after it arose, or it is permanently barred.

19. Governing Law and Venue

These Terms and any dispute arising out of or relating to them or the Services are governed by the laws of the State of Florida and applicable U.S. federal law, without regard to conflict-of-law principles. Subject to Section 18, any such dispute will be brought exclusively in the state or federal courts located in Pinellas County, Florida, and you consent to that jurisdiction and venue. If you live in a jurisdiction whose consumer-protection law gives you rights that cannot be waived by contract, nothing in these Terms limits those rights.

20. Other Provisions

Changes to these Terms. We may update these Terms from time to time. If we make material changes, we will update the “Last Updated” date and may provide notice through the Application or the Website. Your continued use of the Services after the updated Terms take effect constitutes your acceptance; if you do not agree, stop using the Services and cancel any subscription before its next renewal.

Changes to the Services. We may change, limit, or discontinue any part of the Services, including any feature, free tier, or Library Content, at any time. We will try to give notice of changes that materially reduce what a current subscription includes.

General. If any provision of these Terms is held invalid or unenforceable, that provision will be enforced to the maximum extent permitted by law and the remaining provisions will continue in full force. Our failure to enforce any provision is not a waiver. You may not assign these Terms without our prior written consent; we may assign these Terms, in whole or in part, at any time, including to a successor of our business. Except for Apple as described in Section 16, there are no third-party beneficiaries of these Terms. These Terms, together with our Privacy Policy, constitute the entire agreement between you and Coastal Dune Labs regarding the Services and supersede any prior agreement on the subject. Section headings are for convenience only.
