Terms of Use

Last updated: 2026-11-08

These Terms of Use (“Terms”) form a binding agreement between you and the Service Provider and govern your access to and use of WunderCards (the “Application” or “App”), including its free, paid, and AI-powered features, account and synchronization functionality, widgets, notifications, and related backend services.

The Application is developed and operated by Pavel Shorokhov, established in Germany (“Service Provider”, “we”, “us”, “our”).

By downloading, installing, accessing, or using the Application, you confirm that you have read, understood, and agree to these Terms and to our Privacy Policy (Section 19). If you do not agree, do not use the Application and uninstall it.

The Application is provided by us, not by Apple. Your agreement is with us. Apple acts only as the distribution platform (see Section 22).

1. Eligibility

You may use the Application only if you can form a legally binding contract and are at least 16 years old (or the higher minimum age required in your jurisdiction). If you are below that age, you may use the Application only with the consent and supervision of a parent or legal guardian who agrees to these Terms. By using the Application, you represent that these requirements are met.

Parents and guardians are responsible for supervising any minor’s use of the Application and for ensuring that minors do not submit personal, sensitive, unsafe, or third-party content, including through the AI or photo features.

2. What the Application Does

The Application is a flashcard and vocabulary-learning tool that lets you create, store, edit, study, and synchronize vocabulary cards and decks. It may include AI-powered features such as translation, example-sentence generation, part-of-speech detection, and voice-based and photo-based word extraction.

The Application is intended for personal, informal, non-commercial learning, including private use within your household. It is not intended for professional, commercial, or institutional use without our prior written consent.

3. No Professional Advice

The Application does not provide professional, certified, legal, medical, academic, financial, immigration, tax, linguistic, or other expert advice. AI-generated translations, examples, and other output may be inaccurate, incomplete, outdated, biased, or unsuitable.

You must not rely on the Application for legal, medical, official, certified-translation, academic, immigration, financial, tax, or professional purposes, or in any situation requiring accuracy, completeness, or professional verification. In particular, AI-generated translations may contain errors, are not certified translations, and are not a reliable sole source for academic submissions, official or immigration correspondence, or language-examination preparation. You are solely responsible for independently checking any content before relying on it.

4. License

Subject to these Terms and to the Apple Media Services Terms and Conditions, we grant you a limited, personal, non-exclusive, non-transferable, non-sublicensable, revocable license to use the Application on Apple-branded devices that you own or control, as permitted by the Usage Rules in the Apple Media Services Terms.

You may not, except where (and only to the extent) mandatory applicable law expressly permits this notwithstanding this restriction: sell, rent, lease, sublicense, distribute, publish, copy, modify, adapt, translate, reverse-engineer, decompile, disassemble, attempt to derive source code from, circumvent technical limitations of, or create derivative works based on the Application or any part of it.

All rights not expressly granted to you are reserved by the Service Provider and the relevant rights holders.

5. Accounts and Synchronization

The Application may create an anonymous account or identifier to provide functionality, synchronization, quota enforcement, and abuse prevention. You may optionally sign in with Apple or Google to preserve or synchronize your data across devices.

You are responsible for: keeping your device, Apple ID, Google account, and email account secure; the accuracy of information you provide; all activity occurring through your account or device; and maintaining your own independent backups of any important content.

We do not guarantee that accounts, sign-in, or synchronization will be available, uninterrupted, timely, error-free, or free from conflicts, delay, duplication, corruption, or loss of data.

6. AI Features

Certain features rely on third-party AI systems. AI output is generated automatically from your input and may be wrong, incomplete, biased, offensive, infringing, or otherwise unsuitable. You acknowledge that AI output is not independently verified by us, may vary between requests, and that AI features may be unavailable, delayed, limited, throttled, modified, blocked by providers, or discontinued at any time.

You must not submit to AI features any content that is illegal, harmful, abusive, or infringing, and you must not submit special-category personal data, secrets or credentials, payment data, medical, legal, or financial records, images of children, or third-party confidential or personal material, unless strictly necessary and you have the right to do so. You are solely responsible for all words, phrases, text, voice recordings, photos, and other content you submit, and for reviewing any AI output before use.

7. User Content

You retain ownership of the original content you create or submit (e.g. words, translations, examples, notes, deck names, flashcards, voice recordings, photos).

You grant us a non-exclusive, worldwide, royalty-free license to host, store, transmit, process, display, synchronize, and technically adapt that content solely as reasonably necessary to provide, operate, secure, debug, support, and maintain the Application. This includes creating technical copies, caches, and derived or aggregated metadata as reasonably necessary for operation, security, debugging, abuse prevention, quota enforcement, and service improvement, as further described in our Privacy Policy. This license ends when the relevant content is deleted from our active systems, except for content retained in backups, logs, or as required by law (see the Privacy Policy).

You represent and warrant that you have all rights necessary to submit your content and that it does not infringe any third-party right, violate any law, or contain illegal, harmful, abusive, or child-endangering material. We may remove, restrict, block, or report content where we reasonably believe it violates these Terms, the law, third-party rights, platform rules, or the security of the service.

8. Acceptable Use

You agree not to: use the Application for any illegal, harmful, fraudulent, abusive, or infringing purpose; submit illegal, defamatory, hateful, threatening, sexually explicit, child-endangering, or harassing content; circumvent subscriptions, quotas, rate limits, authentication, or access controls; use bots, scripts, scraping, automation, or bulk/programmatic access unless we expressly permit it; perform benchmarking, model or prompt extraction, security or penetration testing, load testing, or automated generation of large volumes of AI requests without our prior written consent; interfere with the operation, security, backend, AI proxy, accounts, or infrastructure of the Application; attempt unauthorized access to any accounts, systems, data, prompts, APIs, or infrastructure; reverse-engineer or tamper with the Application or backend; misuse AI features to generate harmful, illegal, infringing, or abusive content; impersonate any person or misrepresent your affiliation; or use the Application beyond ordinary personal learning use.

9. Illegal Content and Abuse Reports

If you believe that content or activity in the Application is illegal, infringing, or abusive, you may report it to support@llamonade.app. We may review, remove, restrict, preserve, or report content and account activity where reasonably necessary to comply with law, protect users, protect third-party rights, or secure the Application. We may require sufficient information to identify the content or activity and to assess your report. We are not obligated to monitor content proactively.

10. Suspension and Termination

We may, at our reasonable discretion and to the extent permitted by law, suspend, restrict, throttle, block, or terminate your access to the Application, your account, or any feature if we reasonably believe that you have violated these Terms; that your use is abusive, automated, excessive, fraudulent, or harmful; that your use creates legal, security, operational, or financial risk; that your payment, subscription, or entitlement status cannot be verified; that we are required to act by law, platform rules, or a third-party provider; or that continued access may harm the Application, other users, our providers, or us.

Where reasonably possible and legally appropriate, you may contact us about a suspension at support@llamonade.app. We are not required to disclose information that could compromise security, abuse prevention, fraud detection, legal compliance, or the rights of others. Suspension or termination may result in loss of access to data, sync, AI features, paid functionality, or content; you are responsible for keeping your own copies. You may stop using the Application at any time by uninstalling it.

11. Subscriptions and Paid Features

Subscriptions and in-app purchases are sold and processed by Apple through the App Store. Billing, renewal, cancellation, and refunds are governed by Apple’s terms, the App Store rules, and applicable law. We do not receive your full payment details and cannot cancel or refund a subscription on Apple’s behalf.

Paid features, Pro features, usage limits, AI quotas, provider routing, and included functionality may change over time. We may modify, replace, limit, or discontinue features where reasonably necessary for product, security, legal, technical, operational, or provider-related reasons. A paid subscription does not guarantee uninterrupted access to any specific feature; availability may be affected by outages, maintenance, AI-provider limits, platform restrictions, abuse-prevention measures, or technical issues. Nothing in these Terms limits any refund or other right you have under Apple’s policies or mandatory applicable law.

12. Promo Codes and Free Access

We may offer promo codes, trials, or temporary free access. Unless we expressly state otherwise, such access has no cash value, may be limited in duration or functionality, may be changed, revoked, or discontinued at any time, and does not entitle you to any refund or compensation.

13. Availability and Changes to the Application

The Application is a continuously evolving digital service. We may modify, update, suspend, limit, replace, or discontinue any part of it — including free or paid features, AI features, sync, widgets, notifications, backend services, quotas, pricing, or provider integrations — where reasonably necessary for product, security, legal, technical, operational, provider-related, or business reasons. We do not guarantee that the Application or any feature will be available, continue to exist, be compatible with any device, OS version, region, language, or network condition, or that defects will be corrected within any particular time. This Section is without prejudice to your mandatory statutory rights, including, where applicable, the statutory rules on the provision of digital products under German law.

14. Data Loss and Backups

You are responsible for keeping your own backups of any content important to you. The Application, local storage, backend sync, AI features, and third-party services may experience errors, outages, conflicts, deletion, corruption, duplication, or loss of data. The synchronization feature is not an archival backup service; you should keep independent backups of any content that is important to you, for example through your device backup. Subject to Section 16 and to the extent permitted by applicable law, we are not responsible for data loss, sync conflicts, accidental deletion, device loss, operating-system or iCloud behavior, third-party provider failures, or user error.

15. Third-Party Services

The Application relies on third-party services, which may include Apple, Google, AI providers, backend, analytics, crash-reporting, subscription-management, and edge/proxy providers. Your use of such services may be subject to their own terms and privacy policies. When using the Application, you must comply with all applicable third-party terms, including the Apple Media Services Terms and Conditions, the App Store rules, and any applicable network, device, AI-provider, or account-provider terms. Subject to Section 16, we are not responsible for third-party services, outages, decisions, restrictions, pricing, policies, model behavior, or data practices.

16. Disclaimer of Warranties

To the maximum extent permitted by applicable law, the Application is provided “as is” and “as available,” with all faults and without warranty, condition, or representation of any kind. We do not warrant that the Application, AI output, sync, backend services, subscriptions, notifications, widgets, or any content will be accurate, complete, reliable, secure, uninterrupted, error-free, available, fit for a particular purpose, or free from harmful components. You use the Application at your own risk.

Nothing in this Section excludes or limits any warranty, statutory right, or remedy that cannot be excluded or limited under mandatory applicable law, including the mandatory statutory rights of consumers and the statutory liability for defects (Gewährleistung) under German law.

17. Limitation of Liability

17.1 We are liable without limitation for: (a) intent (Vorsatz) and gross negligence (grobe Fahrlässigkeit); (b) injury to life, body, or health resulting from a negligent or intentional breach of duty by us; (c) liability under the German Product Liability Act (Produkthaftungsgesetz); (d) to the extent we have given a guarantee or fraudulently concealed a defect; and (e) any other liability that cannot be limited or excluded under mandatory law.

17.2 For damage caused by simple (ordinary) negligence, we are liable only where we breach a material contractual obligation — i.e. an obligation whose fulfilment is essential to the proper performance of the contract and on whose observance you may regularly rely (a “cardinal obligation”). In that case our liability is limited to the foreseeable damage typical for this type of contract.

17.3 Any further liability for simple negligence is excluded. In particular, and outside the cases in Section 17.1, to the maximum extent permitted by law we are not liable for indirect, incidental, special, consequential, or punitive damages, or for loss of data, profit, revenue, goodwill, or business, or for any reliance on AI-generated content.

17.4 The limitations and exclusions in this Section also apply to claims in tort to the extent permitted by law, and apply equally in favor of our legal representatives, employees, and agents (Erfüllungsgehilfen).

18. Indemnification

Where a third party brings a claim against us because of your culpable breach of these Terms, your unlawful use of the Application, content you submitted without the required rights, or your infringement of third-party rights, you will indemnify us against reasonable losses, damages, and costs (including reasonable legal costs), to the extent permitted by applicable law and only to the extent the claim was caused by your culpable conduct. This does not apply where you are not responsible for the breach.

19. Privacy

Our processing of personal data is described in our Privacy Policy:

https://wundercards.app/privacy

By using the Application, you acknowledge that personal data may be processed as described there. If you do not agree with the Privacy Policy, do not use the Application.

20. Intellectual Property

The Application — including its design, software, code, interface, branding, icons, logos, prompts, workflows, and documentation — is protected by intellectual-property and other laws and remains our property or that of our licensors. You may not use our name, branding, icons, screenshots, or other protected materials except as permitted by law or with our prior written consent. We do not warrant that AI-generated output is unique, protectable, non-infringing, or owned by you; such output may be subject to the applicable AI provider’s terms and to applicable law.

21. Feedback

If you send us ideas, suggestions, bug reports, or other feedback, you grant us, to the extent permitted by law, an unrestricted, royalty-free, perpetual, irrevocable right to use it without any obligation, payment, attribution, or confidentiality, except where otherwise agreed in writing. This does not affect your rights regarding your personal data under our Privacy Policy.

22. Apple-Specific Terms

This Section applies because the Application is licensed via the Apple App Store. In the event of any conflict between this Section and the rest of these Terms, this Section controls solely with respect to your use via Apple:

(a) These Terms are concluded between you and us only, not with Apple. We — not Apple — are solely responsible for the Application and its content.

(b) Apple has no obligation to furnish any maintenance or support for the Application.

(c) To the maximum extent permitted by applicable law, Apple has no warranty obligation with respect to the Application. In the event the Application fails to conform to any applicable warranty that cannot be disclaimed, you may notify Apple, and Apple may refund the purchase price (if any); to the maximum extent permitted by law, Apple has no other warranty obligation.

(d) 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, legal/regulatory, or consumer-protection claims; such claims are governed solely by these Terms and applicable law, subject to the responsibilities we accept under them.

(e) In the event of any third-party claim 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 such claim to the extent required by these Terms and applicable law.

(f) You represent that you are not located in a country subject to a U.S. Government embargo or designated as “terrorist-supporting,” and that you are not on any U.S. Government list of prohibited or restricted parties.

(g) Apple and its subsidiaries are third-party beneficiaries of these Terms and, upon your acceptance, have the right (and are deemed to have accepted the right) to enforce these Terms against you as a third-party beneficiary.

23. Consumer Rights and Mandatory Law

Nothing in these Terms limits or excludes your mandatory rights as a consumer under the law of your country of residence. Where any provision conflicts with mandatory consumer-protection law, that mandatory law prevails and the remaining provisions continue to apply to the maximum extent permitted.

24. Governing Law and Jurisdiction

These Terms are governed by the laws of the Federal Republic of Germany, excluding its conflict-of-law rules and the UN Convention on Contracts for the International Sale of Goods (CISG). If you are a consumer, you also benefit from the mandatory protections of the law of your country of residence, and this choice of law does not deprive you of them. Any dispute shall be subject to the competent courts of Germany, except where mandatory law allows or requires you, as a consumer, to bring or defend claims in the courts of your country of residence.

Information on consumer dispute resolution: We are not obligated and not willing to participate in dispute-resolution proceedings before a consumer arbitration board (Verbraucherschlichtungsstelle).

25. Force Majeure

We are not liable for any failure or delay in performance caused by events beyond our reasonable control, including acts of God, natural disasters, war, terrorism, civil unrest, strikes, epidemics, failures or restrictions of internet, hosting, telecommunications, platform, payment, or AI providers, governmental actions, or other force-majeure events.

26. Changes to These Terms

We may update these Terms from time to time to reflect changes in the Application, legal or regulatory requirements, provider or platform rules, or security, business, or technical needs. The “Last updated” date indicates the current version. For material changes that affect your rights, we will provide reasonable notice by appropriate means where required by law. If you do not agree to the updated Terms, you must stop using the Application and uninstall it; to the extent permitted by applicable law, your continued use after the updated Terms take effect constitutes acceptance.

27. Assignment

You may not assign or transfer your rights or obligations under these Terms without our prior written consent. We may assign or transfer ours in connection with a merger, acquisition, sale of assets, restructuring, change of service provider, or by operation of law, provided this does not unlawfully reduce your mandatory consumer rights.

28. Severability and Entire Agreement

If any provision is held invalid or unenforceable, the remaining provisions remain in effect, and the invalid provision is replaced — to the extent permitted by law — by a valid one that most closely reflects its original purpose and economic intent. These Terms, together with the Privacy Policy and any Apple terms that apply, constitute the entire agreement between you and us regarding the Application and supersede any prior understanding on that subject, except for mandatory statutory rights.
