Terms and Conditions

Effective date: September 27, 2026 Last updated: September 27, 2026

These Terms and Conditions (“Terms”) govern your use of the Avocards mobile applications, websites and related services (the “Service”). The Service is provided by CALEAVO (“Avocards”, “we”, “us”, or “our”).

By creating an account, purchasing a product or using the Service, you agree to these Terms and our Privacy Policy. If you do not agree, do not use the Service.

1. Operator

CALEAVO 8th floor, Number F870 191 Dongbaekjungang-ro, Giheung-gu Yongin, Gyeonggi 17006, Republic of Korea info@caleavo.com +82 10-2683-5235

2. Eligibility and accounts

Avocards is not directed to children under 13. You must be at least 13, or the higher minimum age required in your country, to create an account without verifiable parental permission. If you are under the age of legal majority where you live, a parent or legal guardian must review and accept these Terms for you.

You must provide accurate account information, protect your credentials and promptly tell us if you suspect unauthorised access. You are responsible for activity performed through your account unless applicable law provides otherwise. You may not create accounts through automated means, impersonate another person or evade a suspension.

3. The learning service

Avocards provides flashcards, lessons, review games, audio, K-pop learning material, scanning, custom cards, AI-assisted tools and related progress features. Some features work offline; synchronisation, generation, public content, purchases and other features require an internet connection.

Learning content may contain errors or regional differences. Avocards is an educational aid, not a certification programme or a substitute for a qualified teacher, translator or other professional. Please report errors so we can review them.

We may improve, replace or discontinue a feature. If a change materially affects a paid service, we will provide the notice or remedy required by applicable law.

4. Premium, subscriptions and purchases

Some features require Premium, a subscription, a lifetime product or virtual items. The app shows the current price, billing period, trial terms and included benefits before purchase. Prices and availability can vary by platform, country and tax rules.

Mobile purchases are processed by Apple App Store or Google Play, not directly by Avocards. Their payment, cancellation and refund rules apply in addition to mandatory consumer law.

• An auto-renewable subscription renews for the displayed period unless you cancel it through your Apple or Google account before the renewal deadline shown by the store.
• Uninstalling Avocards or deleting your Avocards account does not cancel store billing.
• You can restore eligible purchases using the store account that made the purchase.
• Refund requests are handled by Apple or Google unless applicable law requires Avocards to provide a remedy.
• A lifetime product provides access for the supported lifetime of that product and account; it does not guarantee that every current or future feature will remain unchanged forever.

Nothing in these Terms limits a mandatory cancellation, refund, conformity or other consumer right.

5. Coins, hints, credits and rewards

Coins, hints, AI credits, streak shields, XP and similar items are limited licences to use features inside Avocards. They are not money, property, a stored-value account or a transferable financial instrument. They cannot be exchanged for cash, sold or transferred unless Avocards expressly provides that function.

We may set earning rules, balances, daily limits and abuse protections. We will not remove purchased virtual items arbitrarily, but may correct duplicate, fraudulent or erroneous grants and may change free reward mechanics with reasonable notice where appropriate. Unused virtual items may be lost when an account is deleted.

6. AI features

Avocards offers optional AI features through a third-party provider, currently OpenAI. Choosing Generate or Analyse requests that Avocards send the content described below to OpenAI for processing. If you do not want content sent to OpenAI, do not use the AI feature.

Grammar analysis

Grammar analysis sends the sentence you submit and language instructions to generate an explanation. Do not submit confidential or sensitive personal information. The result may be incomplete or wrong and should be independently checked before important use.

Dialog generation

Dialog generation sends selected vocabulary and language context to produce a practice dialog, translations and annotations. Generated conversations are fictional unless the feature clearly says otherwise.

AI-generated custom cards

AI custom-card generation sends the word, optional meaning, selected language and necessary instructions to generate definitions, examples, translations and related content. If you save an AI-generated card as public, Avocards may translate it into supported languages, generate pronunciation audio, moderate it and make it searchable by other users.

Scanning

Scan import recognises text from an image on your device and sends recognised text to Avocards to find cards and resolve conflicts. We do not claim ownership of the source image. You must have the right to process the material you scan.

AI limitations

AI outputs may be inaccurate, outdated, offensive, incomplete or unsuitable for your context. They are provided for language-learning assistance and are not legal, medical, financial or other professional advice. Do not rely on AI output where an error could cause harm. We may limit generation, apply quotas, reject unsafe requests or remove generated content.

You remain responsible for reviewing content before saving, sharing or relying on it. To the extent permitted by law, Avocards does not guarantee that an AI output is unique or that the same or similar output will not be generated for another user.

7. Your content and custom cards

You retain the rights you have in content you submit. You confirm that you have the rights and permissions needed to submit and use it.

Private content

Manual custom cards are private by default. You grant Avocards a limited, worldwide licence to host, copy, process, translate, back up and display private content only as needed to operate, secure and improve the requested Service for you.

Public content

When you deliberately publish a card, category or other contribution, you grant Avocards a non-exclusive, worldwide, royalty-free licence to host, reproduce, format, translate, generate related audio, display, distribute and make that public content available through the Service. The licence lasts while the content remains public and for a reasonable operational period afterward, except that copies lawfully saved into another user’s collection and anonymised catalogue records may remain where permitted by law.

Publishing does not transfer ownership to Avocards. You can request removal, but removal may not retract copies already independently saved or information we must retain by law. Our Privacy Policy explains the treatment of personal information.

We may review, reject, label, restrict or remove content that violates these Terms or may harm the Service or its users. Moderation is not a guarantee that all content is accurate, safe or lawful.

8. Acceptable use

You must not:

• violate law or another person’s privacy, publicity, copyright, trademark or other rights;
• upload malware or attempt to access accounts, systems or data without permission;
• scrape, copy, resell or systematically extract the Service or catalogue except as expressly allowed;
• reverse engineer or bypass access, rate, payment, moderation or security controls except where law expressly permits it;
• use automation to create accounts, generate abusive load, manipulate rewards or obtain more credits than allowed;
• publish harassment, threats, hate, sexual exploitation, unlawful obscenity, dangerous instructions or personal information without permission;
• use the Service or AI features to deceive, impersonate, defraud or cause harm; or
• interfere with other users or the operation of the Service.

We may investigate suspected violations and restrict or suspend access proportionately. Where appropriate, we will give notice and an opportunity to appeal, unless doing so would create a security or legal risk.

9. Avocards content and intellectual property

The Service, software, design, branding and Avocards-created catalogue are owned by or licensed to CALEAVO and protected by applicable law. Subject to these Terms, we grant you a personal, limited, non-exclusive, non-transferable and revocable licence to use the Service for lawful personal learning.

Dictionary entries, audio, videos, music, lyrics, images and other third-party materials remain subject to their owners’ rights and licences. Availability of a third-party link or embedded item does not mean Avocards owns or endorses it.

If you believe content infringes your rights, email info@caleavo.com with your contact details, identification of the work and material, its location, the basis of your claim and a good-faith statement that the information is accurate. We may request additional verification.

10. Advertising, links and third-party services

The free Service may contain advertising. The Service also relies on Apple, Google, OpenAI, RevenueCat, OneSignal and other third-party services described in the Privacy Policy. Their own terms may apply. Avocards is not responsible for an unrelated third-party website or service merely because the Service links to or interoperates with it.

11. Account deletion, suspension and termination

You may stop using the Service at any time. To delete your account and associated data, use Settings > Remove personal data or follow the Account and Data Deletion instructions. Cancel any store subscription separately before deletion.

We may suspend or terminate access when reasonably necessary to address fraud, abuse, legal risk, non-payment, security threats or a material breach of these Terms. We will use proportionate measures and provide notice where reasonably possible and legally permitted.

After termination, rights that by their nature must continue—including payment obligations already incurred, intellectual-property protections, public-content licences, disclaimers and dispute provisions—survive. Data is handled as described in the Privacy Policy.

12. Availability and disclaimers

We work to keep Avocards available and reliable, but the Service may be interrupted by maintenance, connectivity, provider failures or events outside our reasonable control. To the maximum extent allowed by law, the Service is provided “as is” and “as available” without a promise that it will always be uninterrupted, error-free or suitable for every learning goal.

These disclaimers do not exclude warranties, remedies or responsibilities that cannot legally be excluded, including mandatory consumer protections.

13. Limitation of liability

Nothing in these Terms excludes liability for fraud, wilful misconduct, gross negligence, death or personal injury caused by negligence, or any other liability that cannot be excluded under applicable law.

To the extent permitted by law, CALEAVO is not liable for indirect or consequential loss, loss of opportunity, or loss caused by reliance on learning or AI output when such loss was not reasonably foreseeable when you accepted these Terms. Any limitation is subject to the mandatory consumer law that applies to you.

14. Indemnity for business or unlawful use

If you use the Service on behalf of a business, or your intentional unlawful conduct causes a third-party claim against CALEAVO, you agree to reimburse reasonable losses and costs resulting from that conduct to the extent permitted by law. This section does not apply where prohibited by consumer law and does not require you to cover losses caused by CALEAVO.

15. Governing law and disputes

These Terms are governed by the laws of the Republic of Korea, without depriving you of mandatory protections that apply in your country of residence.

Please contact info@caleavo.com first so we can try to resolve a dispute informally. If it cannot be resolved, disputes may be brought before the courts having jurisdiction under applicable Korean procedural law, unless mandatory consumer law allows you to bring a claim in another competent court. Nothing here prevents either party from seeking urgent protective relief or using an applicable consumer dispute-resolution process.

16. Changes to these Terms

We may update these Terms to reflect legal, security or product changes. We will update the date above and provide reasonable advance notice of a material adverse change where required. If you do not agree to revised Terms, stop using the Service and, if desired, delete your account before they take effect. Changes do not retroactively reduce rights already accrued unless law permits it.

17. General provisions

If a provision is unenforceable, it will be adjusted only as much as needed and the remaining provisions continue. Our failure to enforce a provision is not a waiver. We may assign these Terms as part of a merger, reorganisation or transfer of the Service with appropriate notice and protection; you may not transfer your account or rights without our permission.

The English version is the controlling version unless local law requires otherwise. A translated version is provided for convenience and should be interpreted consistently with the English version.
