1. Agreement and provider
These Terms govern your use of yoyolingo, provided by HappyCalf Media LLC, 30 N Gould St Ste N, Sheridan, WY 82801, United States (“we,” “us,” or “yoyolingo”). By creating an account, purchasing a plan, or using the service, you agree to these Terms.
2. Eligibility and service regions
The Services are intended only for users who are at least 18 years old. By creating an account or using the Services, you represent that you are at least 18 years old. Persons under 18 are not permitted to use or register for the Services. We may restrict or close an account if we reasonably believe that this requirement has not been met.
At launch, account registration, online services, and paid plans are offered in Japan, South Korea, the United States, Canada, Australia, New Zealand, Hong Kong, Singapore, Malaysia, Mexico, Argentina, Colombia, and Brazil. They are not offered, marketed, or sold to persons located in the European Economic Area (“EEA”), comprising the 27 European Union Member States, Norway, Iceland, and Liechtenstein, or the United Kingdom. Availability in other markets may vary, and we may decline registration or payment where applicable restrictions prevent us from providing the Services.
3. The service
yoyolingo is a desktop language-learning tool for media you import. It can prepare audio or video for sentence-by-sentence playback, vary speed and repetition, show or generate subtitles and translations, provide vocabulary definitions, and export saved words. Machine-generated transcriptions, translations, pronunciations, and definitions can be inaccurate and are learning aids, not professional advice.
4. Your media and acceptable use
You are responsible for ensuring that you may lawfully access and use media you import. You must not use yoyolingo to infringe copyright, bypass DRM or access controls, distribute unauthorized copies, break the law, harm others, interfere with the service, probe its security, or misuse automated systems. yoyolingo does not supply, search, or host third-party media catalogs.
5. Accounts and security
You must provide accurate account information, confirm that you meet the age requirement, and protect access to your email and devices. Tell us promptly about suspected unauthorized use. We may restrict or suspend access when reasonably necessary to protect users, the Services, or comply with law.
6. Plans, promotional credits, renewal, and payment
Plan terms, translation allowances, validity periods, and renewal behavior are shown before purchase. “Translation minutes” means the aggregate duration of translated media, not application usage time.
Eligible new users may claim a one-time introductory allowance of 200 minutes of AI translation use, valid for 7 days from activation. During registration, a user may optionally enter a referral code. When a valid referral code is redeemed, the invited user and the referring user may each receive 200 minutes of promotional AI translation use, valid for 7 days. A referral code may be redeemed only once, and each eligible referring user may be issued no more than two referral codes. Promotional credits are non-transferable, have no cash value, may not be sold or exchanged, and do not automatically renew. We may withhold, adjust, or revoke promotional credits where reasonably necessary to prevent fraud, abuse, error, or violation of these Terms.
Monthly Membership automatically renews each Paddle billing period until cancelled and includes 50 hours of translated media in each monthly allowance period. Its standard allowance refreshes when Paddle starts the next paid billing period, and unused standard allowance does not carry forward. 30-Day Membership is a one-time product valid for 30 days from activation and includes one 50-hour standard translation allowance with no scheduled refresh.
Six-Month Membership is a one-time product valid for 6 months from activation, and Annual Membership is a one-time product valid for 12 months from activation. Expiration falls on the corresponding UTC date and time; if the destination month has no corresponding date, expiration falls on that month’s final day at the same UTC time. Each product includes 50 hours of translated media in each monthly allowance period: the first period starts at activation and the allowance refreshes on each monthly anniversary of the original activation date. If a month has no corresponding date, that month’s allowance boundary falls on its final day at the same UTC time; later boundaries remain anchored to the original activation date. No new allowance is granted at expiration, and unused standard allowance does not carry into the next period.
Translation Top-Up is a one-time add-on available only to users with an active membership. It includes 25 translation hours. Its balance may be used only while the underlying membership remains active or in an applicable grace period, and expires 30 days after purchase regardless of membership status. Standard membership allowance is used before Translation Top-Up balance; if more than one Translation Top-Up is active, the balance that expires first is used first. 30-Day Membership, Six-Month Membership, Annual Membership, and Translation Top-Up do not automatically renew. The applicable price, billing period, renewal terms, and cancellation method will be displayed before purchase.
Payments are processed through Paddle, which may act as merchant of record for applicable transactions. Payment methods, taxes, billing, receipts, refunds, and chargebacks are subject to the information displayed at checkout, the applicable Paddle terms, and mandatory consumer rights.
7. Cancellation and refunds
You may cancel Monthly Membership at any time by logging in to your account and using the subscription-management link to access the Paddle Customer Portal. Cancellation takes effect at the end of the then-current paid term. 30-Day Membership, Six-Month Membership, Annual Membership, and Translation Top-Up do not require cancellation because they do not automatically renew. Refunds are governed by our Refund Policy, Paddle’s checkout terms, and mandatory consumer rights in your location.
8. Intellectual property
We and our licensors retain rights in the application, branding, software, design, and service. You retain rights you hold in your imported media and learning data. These Terms grant a limited, personal, non-transferable right to use yoyolingo while your access is valid.
9. Availability and changes
We may update the service for security, compatibility, legal, or product reasons. Online features can be unavailable due to maintenance, networks, providers, or events outside our control. We will provide reasonable notice of material changes when required, including by posting an updated version and, where required, by email.
10. Disclaimers and liability
To the maximum extent permitted by law, the service is provided “as is” and “as available.” We do not guarantee uninterrupted operation or error-free AI output. Nothing excludes liability or consumer rights that cannot lawfully be excluded. To the extent permitted by law, HappyCalf Media LLC is not liable for indirect, incidental, special, consequential, or lost-profit damages arising from use of the service.
11. Governing law and disputes
These Terms are governed by the laws of Wyoming, United States, without regard to conflict-of-law rules. Courts located in Sheridan County, Wyoming have jurisdiction, except where mandatory consumer law gives you the right to bring a claim elsewhere. Before filing a claim, please contact us and allow a reasonable opportunity to resolve it informally.
