Terms of Service

1. Eligibility

By using the Service you confirm that you:

• are at least 14 years old — and, if you are under 18 or under the age of majority where you live, that you use the Service with the consent and supervision of a parent or legal guardian, who accepts these Terms on your behalf;
• are at least 18 years old if you buy a plan or credits;
• have read and agree to these Terms, our Privacy Policy (melunox.com/legal/privacy) and our Acceptable Use Policy (melunox.com/legal/acceptable-use);
• have the authority to bind the organisation, if you use the Service on behalf of one — “you” then means that organisation.

You may not use the Service if the law forbids it, or if we have previously suspended your account.

2. Where the Service is offered

The Service is not offered in mainland China (the People’s Republic of China, excluding the Hong Kong SAR, the Macao SAR and Taiwan). Please do not create an account, make a purchase or use the Service from mainland China. We may decline, suspend or close accounts we have reason to believe are used from there.

You are responsible for complying with the laws that apply where you are.

3. The Service

Melunox is an AI-powered platform for making music: writing and editing lyrics, generating songs and instrumentals, cover art and music videos, separating vocals and stems, converting audio to MIDI, reading sheet music, and related tools. It is a digital software-as-a-service product delivered over the internet.

The Service is digital and intangible. Plans and credits are delivered to your account as soon as payment is confirmed, which is why refunds are limited as set out under “Refunds” below.

The Service relies on third-party AI models and the providers that host them. They are listed, by feature, on our AI Models page (melunox.com/legal/ai-models). Their availability affects ours: when one is unavailable, a request may be handled by another model listed for the same purpose. We will tell you promptly about significant disruptions. Melunox is independent and is not affiliated with or endorsed by any model provider.

4. Your account

You must give accurate information when you register and keep it up to date. You are responsible for keeping your sign-in credentials confidential and for everything done under your account.

• Tell us immediately at security@melunox.com if you suspect unauthorised use of your account.
• Do not share your credentials with anyone.
• Keep the email address on your account current — receipts and billing notices go there.

5. Plans and credits

We offer a free plan; subscription plans (Base, Pro and Ultra, billed monthly or yearly) that include a monthly allowance of credits; and credit packs, bought one at a time while you have an active subscription. Current plans, prices and what each includes are on our Pricing page (melunox.com/pricing).

Credits are spent on generation features at the price shown in the product before you start an action. Credits have no cash value, cannot be transferred, sold or exchanged for money, and are not a stored-value product.

We may change plans, features or prices. A price change for an existing subscription takes effect from your next billing period, after at least 14 days’ notice by email; you can cancel before it applies.

6. Billing and payment

Orders are processed by our online reseller and Merchant of Record, Waffo Pancake (Waffo.com Limited), which sells plans and credit packs to you on our behalf, charges your payment method, issues your receipt, handles order-related enquiries and returns, and handles applicable sales taxes. Your card statement may show Waffo Pancake and/or MELUNOX.

Subscriptions — recurring authorisation. By subscribing, you expressly authorise us, through Waffo Pancake, to charge your payment method at the start of each billing period (monthly or yearly) for the plan’s price plus applicable taxes, until you cancel as described under “Cancellation”. Subscriptions renew automatically at the end of each billing period unless cancelled. We email yearly subscribers a reminder about 7 days before each renewal.

Credit packs. Each credit pack is a one-time purchase authorised at checkout. We do not offer automatic top-ups.

Taxes. Prices on the Pricing page are in US dollars and exclude applicable taxes unless stated. Taxes such as VAT, GST or sales tax are calculated at checkout from your location and shown before you pay.

Failed payments. If a renewal payment fails, your subscription may be marked past due and its plan credits withheld until payment succeeds; Waffo Pancake may retry the charge.

7. Cancellation

You can cancel your subscription at any time:

• online, under Account → Billing → Cancel subscription (recommended); or
• by email from the address on your account to support@melunox.com. We confirm cancellation by email.

Cancellation takes effect at the end of the current billing period: you keep your plan and its credits until then, and you will not be charged again. Credit packs bought separately are not affected and stay in your balance.

8. Refunds

Because plans and credits are delivered immediately, payments are generally non-refundable, except as follows.

Subscriptions:

• First-time subscribers: a full refund if you ask within 7 days of your first subscription charge and have used no more than 20% of the credits included in that billing period.
• Yearly plans: in addition, within 30 days of the initial yearly charge you may ask for a pro-rated refund of the whole months not yet started. After 30 days, yearly fees are non-refundable.
• Duplicate charges: always refunded in full.
• Service failure: if the Service is unavailable for 72 consecutive hours or more for reasons within our control, a pro-rated refund or credit for the affected time.
• Credit packs: a full refund within 7 days of purchase if none of that pack’s credits have been used. Credits that have been used are non-refundable.

How credits behave: plan credits are issued at the start of each monthly period (yearly plans included) and expire at its end — they do not roll over. Credit packs do not expire, and stay usable after a subscription ends. When you have both, plan credits are used first, then credit-pack credits.

Statutory rights: if the law where you live gives you a right of withdrawal or a refund — such as the 14-day right of withdrawal for consumers in the EU and UK — that right applies. By starting to use credits you ask us to begin performance immediately and acknowledge that you lose the right of withdrawal for what you have used, where the law allows this.

How to ask: email support@melunox.com with your account email, the order or transaction ID and the reason. We acknowledge within 2 business days and process eligible refunds within 5–10 business days, to the original payment method, through Waffo Pancake.

Not refundable: billing periods already used (except as above); used credits; yearly fees after 30 days; and accounts terminated for breaching these Terms or the Acceptable Use Policy.

9. Billing disputes

If you think a charge is wrong, please contact us at support@melunox.com before disputing it with your bank or card issuer. We reply within 2 business days and correct confirmed billing errors within 5 business days.

10. Your content and the licence you grant us

“Your Content” means the inputs you submit (prompts, lyrics, uploaded files, settings) and the outputs generated for you. As between you and us, you keep all rights you have in Your Content.

You grant us a worldwide, non-exclusive, royalty-free licence to host, store, copy, process, transmit and display Your Content only to operate, secure and provide the Service to you and to the collaborators you choose. For content you publish, the licence extends to showing it to the audience you chose.

The licence ends when you delete Your Content or your account, except for copies others have already legitimately accessed, copies we must keep by law, and backups until they expire, as described in our Privacy Policy.

11. AI output and intellectual property

Ownership. As between you and us, the outputs generated from your inputs belong to you. To the extent we hold any rights in them, we assign those rights to you on generation, subject to these Terms and to the rights of third parties, including the terms of the model providers. Copyright in AI-assisted works varies by country and may be limited or unavailable; we make no promise that an output is protectable or free of third-party claims.

We never train on your content. We do not use your inputs or outputs to train, fine-tune or improve any AI model, and we never sell them. Model providers process them only to produce your output.

Quality and similarity. AI output is probabilistic. It may be imperfect or inaccurate and may resemble existing works. Review it before you rely on, release or distribute it. We do not guarantee particular results, and outputs depend on third-party models.

AI labelling. Output from the Service is AI-generated, and public song pages say so. Do not remove that label or present AI-generated work as wholly human-made where that would mislead.

Uploads. Only upload recordings, videos, images and sheet music you own or have permission to use; tools that work on an upload ask you to confirm this. Results made from an uploaded recording or video — such as covers, separated stems or lip-sync videos — are for your own use and cannot be published on Melunox.

12. Acceptable use

You must follow our Acceptable Use Policy (melunox.com/legal/acceptable-use), which sets out what may not be generated, how we moderate content, and how to report and appeal. In particular, you agree not to:

• generate or share content that is illegal, defamatory, harassing, hateful, sexually explicit or fraudulent;
• generate, distribute or facilitate deepfakes — AI-synthesised audio, video or images that impersonate a real person, including imitating an identifiable singer’s voice or using someone’s face without consent, or that mislead people about their origin;
• generate content that sexualises minors or otherwise endangers children;
• infringe anyone’s copyright, trademark, publicity, privacy or other rights, including by uploading material you have no right to use;
• produce malware, phishing content or tools for cyberattacks;
• circumvent or interfere with the Service’s security, rate limits or content filters, including with jailbreak prompts;
• resell, sublicense or share access to the Service without our written approval;
• use inputs, outputs or any part of the Service to train, fine-tune, benchmark or distil an AI model that competes with the Service;
• scrape or harvest outputs at scale beyond your own authorised use;
• present AI output as the work of a human professional where that could cause harm;
• violate any applicable law, regulation or card-network rule.

13. Moderation, suspension and termination

We screen prompts and generated content automatically and review flagged and reported content, as described in the Acceptable Use Policy. We may refuse, restrict or remove content, and limit, suspend or terminate accounts, for breach of these Terms or that Policy, for legal or security risk or suspected fraud, or where the law requires. Where practicable and lawful we tell you and offer an appeal.

If we terminate your account for a reason other than your breach, we refund the unused prepaid part of your subscription pro rata.

You can delete your account at any time in your account settings. Unused credits end with the account and are not refundable except as set out under “Refunds”. Terms that by their nature should survive termination — ownership, disclaimers, limitation of liability, indemnity, governing law — continue to apply.

14. Our intellectual property; third-party services

The Service — its software, design and the Melunox name and marks — belongs to us or our licensors. These Terms give you no rights in them beyond the limited right to use the Service.

The Service integrates third parties (AI model providers, payment processing, hosting). We are not responsible for third-party services, and your use of them may be subject to their own terms.

15. Disclaimers and limitation of liability

THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE”, WITHOUT WARRANTIES OF ANY KIND, EXPRESS, IMPLIED OR STATUTORY, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, OR THE ACCURACY OF AI OUTPUT. Some jurisdictions do not allow certain disclaimers, so some of these may not apply to you.

AI-generated content may be inaccurate, incomplete or similar to existing works. Do not rely on it for legal, medical, financial or other professional advice.

TO THE MAXIMUM EXTENT PERMITTED BY LAW, WE ARE NOT LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL OR PUNITIVE DAMAGES, OR FOR LOSS OF PROFITS, DATA OR GOODWILL. OUR TOTAL LIABILITY FOR ANY CLAIM RELATING TO THE SERVICE IS LIMITED TO THE GREATER OF THE AMOUNT YOU PAID US IN THE 12 MONTHS BEFORE THE CLAIM AND USD 100. Liability that cannot be limited by law is not limited.

16. Indemnification

To the extent the law allows, you will indemnify us against claims arising from Your Content or from your breach of these Terms or the law.

17. Governing law and disputes

These Terms are governed by the laws of the People’s Republic of China (for this purpose excluding the laws of the Hong Kong SAR, the Macao SAR and Taiwan), without regard to conflict-of-laws rules.

Before starting formal proceedings, please contact us at legal@melunox.com so we can try to resolve the matter informally.

Any dispute that cannot be resolved informally within 30 days shall be submitted to the Shenzhen Court of International Arbitration (Shenzhen Arbitration Commission) for arbitration in Shenzhen under its arbitration rules in force at the time of application. The arbitration shall be conducted in Chinese or English, and the award is final and binding on both parties.

Nothing in this section takes away the mandatory consumer protections of the country where you live.

18. Changes to these Terms

We may update these Terms. We will tell you about material changes by email at least 14 days before they take effect; the date at the top shows the current version. Continuing to use the Service after a change takes effect means you accept the updated Terms. If any provision is found unenforceable, the rest remains in effect.
