MyMelos Terms of Service

Effective Date: October 9, 2026

Company: BitDynamic (Shenzhen) Technology Co., Ltd.

Product: MyMelos

1. Your Agreement with Us

These Terms of Service (“Terms”) form a binding agreement between you and BitDynamic (Shenzhen) Technology Co., Ltd. (“BitDynamic,” “we,” “us,” or “our”) and govern your use of MyMelos — including the mobile app, our website, the web console, MyMelos Chat, and every song generation, lyric, voice, and music feature we provide (together, the “Service”).

Please read these Terms together with our Privacy Policy before you start. By tapping “Agree,” “Sign Up,” “Log In,” or “Purchase,” or by downloading, browsing, or otherwise using the Service, you confirm that you have read and accepted these Terms. If you do not accept them, please do not use the Service.

We may revise these Terms periodically. When we do, we post the new version in the app or on our website and update the effective date above. If a revision materially changes subscription pricing, your core rights or duties, the scope of data processing, or similarly important matters, we will give you notice — through an in-app message, a notification, or an email — before it takes effect, unless the law says otherwise. Continuing to use the Service once a revision is in force means you accept it.

How to reach us:

2. What MyMelos Does

MyMelos is a creative tool built on generative artificial intelligence. It takes the material you give it — text, prompts, lyrics, images, photos, audio, voice samples, video, and style or mood settings (“Inputs”) — and produces songs, vocals, lyrics, arrangements, instrumentals, remixes, voice models, and other results (“Outputs”). We call Inputs and Outputs together “Content.”

Because AI works by probability rather than certainty, Outputs are not guaranteed to be unique. Different users who give the same or similar Inputs may receive identical, close, or hard-to-tell-apart results. Unless these Terms expressly say otherwise, the fact that the Service produced a similar Output for someone else does not, by itself, mean that BitDynamic or that other user has infringed your rights.

The Service also includes an AI assistant we call “MyMelos Chat,” which helps with prompt writing, lyrics, creative direction, settings, and guidance. Without our prior written permission, you may not use its conversation history, prompts, responses, interface behaviour, or the way the system reacts in order to train outside models, analyse competitors, reverse engineer the Service, hunt for vulnerabilities, bypass safety controls, or run adversarial tests.

2.1 Outside AI Providers

Generating a song requires specialised models, so the Service calls on outside artificial intelligence providers (“AI Providers”) as needed. Depending on the feature, your prompts, keywords, lyrics, genre or mood choices, audio, images, and other required Inputs may be passed to those providers for near-instant processing.

Our current and potential AI Providers include Suno, Inc. (music generation, vocal synthesis, and arrangement), Anthropic PBC (Claude, for prompt handling, lyric assistance, and instruction writing), and OpenAI, LLC (ChatGPT, for prompt generation, multimodal understanding, and responses). Which providers we use may change with our features, your region, model availability, and technical configuration.

Those services belong to their own providers and are subject to their terms, policies, and technical limits. Apart from the limited right to use the Service that these Terms give you, nothing here grants you ownership of or rights in any outside model, interface, system, technology, or service. How we handle personal data in this context is described in our Privacy Policy.

3. Accounts, Age, and Legal Compliance

3.1 Registering and looking after your account

Some features — saving songs, subscribing, or using advanced generation — need an account. Please give accurate, complete, and current details, and keep your sign-in credentials safe. To the extent the law allows, you are responsible for losses that result from failing to protect your credentials or to tell us promptly about suspicious activity.

If you think your account has been accessed without permission, your credentials have leaked, or you spot unusual transactions or generation activity, contact us right away at service@bitdynamic.co.

3.2 Free tiers and fair use

We may offer free tiers, trial credits, or promotional allowances with limited generation capacity. You may not collect, stack, resell, or misuse free credits by creating multiple accounts, using throwaway email addresses, sharing accounts, running scripts, bots, or crawlers, hiding behind proxy pools, using false identities, or other improper means.

If we reasonably conclude that an account is bound up with fraud, account farming, unusual transactions, billing evasion, misuse of a payment instrument, free-tier abuse, or activity that undermines platform security, we may — as the law permits — limit features, freeze credits, require verification, withdraw irregular benefits, block linked accounts, decline refunds, or take other necessary steps. Where it is reasonably practicable, we will tell the affected user the main reason, unless legal, regulatory, safety, or anti-fraud concerns say otherwise.

3.3 Age limits and younger users

The Service is for people aged 13 and over. Where the law in your country or region sets a higher minimum, that higher age applies, and if you are below it you must not sign up or use MyMelos.

Anyone aged 13 to 17, or anyone who has not yet reached the age of majority in their home jurisdiction, may only use MyMelos with a parent's or legal guardian's awareness, permission, and continued oversight. Where the law, a platform's rules, or our own risk controls call for it, we may require you or your guardian to confirm your age, your guardianship relationship, or your consent. Should that confirmation not be provided, we can suspend or restrict the features concerned.

Platform age signals (planned). To keep younger users in an age-appropriate experience, honour our duties to protect minors, and keep unsuitable features beyond their reach, we may later — where the platform supports it and where the law together with any user or guardian authorisation permits it — read the age bands, age categories, and guardian-approval outputs that tools such as Google's Play Age Signals and Apple's Declared Age Range make available. Such outputs would not ordinarily carry a full date of birth or identity paperwork. We would use them only in the ways our Privacy Policy describes: age-appropriate experiences, feature limits, safety, risk control, legal compliance, and minor protection. If those outputs are missing, not applicable, or insufficient to satisfy legal requirements, we may seek a different reasonable form of age or consent confirmation from you or your guardian.

3.4 Sanctions, export controls, and regional limits

You confirm that you do not appear on any sanctions, restricted-party, embargo, or export-control list kept by the United Nations, the United States, the European Union, the United Kingdom, China, or any other applicable authority, and that you will not use the Service in breach of export-control, trade-sanctions, anti-money-laundering, counter-terrorism-financing, or similar laws. We may lawfully restrict access by particular countries, regions, entities, or accounts.

3.5 App store terms

These Terms are between you and BitDynamic alone. Neither Apple Inc. nor Google LLC nor any of their group companies is a party to them, though if you obtained the app through their platforms you must also follow the applicable store terms. For the iOS version, to the extent the law allows, Apple and its subsidiaries may be third-party beneficiaries of the parts of these Terms that concern the Apple-distributed app.

3.6 Using the web version

When you reach the Service through our website, web app, or web console, we may use cookies, local and session storage, pixel tags, SDKs, and device identifiers to support sign-in, guard your account, deter fraud, process checkout, remember your language and region, measure performance, diagnose errors, help us improve the product, and — where the law allows — attribute marketing. Strictly necessary cookies are normally indispensable to sign-in, checkout, security, and the core features. You can control non-essential cookies through your browser or any preference tool we provide, though switching some off can stop sign-in, payment, subscription management, content saving, or the rest of the web features from working.

The web version may connect with services from Stripe, PayPal, cloud hosting, fraud screening, analytics, email, and customer support, or with other outside parties. Those parties may handle payment, security, risk-control, or technical data under their own terms and privacy policies. Our Privacy Policy explains this processing in more detail.

4. Content, Licences, and Commercial Rights

4.1 Our intellectual property

Apart from your Inputs and the rights these Terms expressly give you, everything behind the Service — the software, interfaces, models, algorithms, architecture, databases, APIs, SDKs, brand names, logos, documentation, visual design, workflows, model weights, and training methods — belongs to BitDynamic or its licensors. Without our prior written consent, you may not reproduce, alter, distribute, sell, rent, disassemble, decompile, defeat protective measures on, or otherwise make use of our intellectual property.

4.2 Your Inputs stay yours

You keep whatever rights you lawfully hold in the Inputs you submit. You confirm that you have every right, consent, and permission needed to use, upload, submit, and have us process those Inputs, and that they do not infringe or misappropriate anyone's copyright, trademark, trade secret, likeness, publicity, privacy, biometric rights, or other lawful interest.

4.3 The licence we need to run the Service

So that we can operate, maintain, secure, debug, improve, and deliver the Service, you grant BitDynamic and the suppliers we need a worldwide, non-exclusive, royalty-free licence — sublicensable only where necessary — to host, copy, cache, transmit, reformat, process, analyse, render, store, display, review, and return your Inputs and Outputs. That licence is limited to what the Service, these Terms, our safety and security needs, the features you request, our legal duties, and the protection of legitimate interests require.

Once you delete Content or close your account, we delete or anonymise it within the retention periods in the Privacy Policy, unless keeping it is reasonably necessary for legal compliance, disputes, security audits, backup rotation, anti-fraud, Content you posted publicly, or remix and collaboration features you switched on.

4.4 AI training and product improvement

Unless you give separate express consent or make the relevant Content public, we will not use your private projects, original voice recordings, voiceprints, personal voice models, Content held in a minor's account, or private material that plainly carries sensitive personal information to train, fine-tune, or develop foundation models offered to the public or to third parties.

For Outputs you choose to publish, public remixes, public settings, general prompts, feedback, aggregated or anonymised data, and data you authorise, you allow us — as the law permits — to use it to improve, test, evaluate, fine-tune, and train our models, safety systems, and features. We apply access limits, permission separation, de-identification, aggregation, anonymisation, and retention controls, as described in the Privacy Policy.

4.5 What you may do with Outputs

Paid subscribers. While your paid subscription is active, your payment is complete, and you comply with these Terms, BitDynamic assigns or grants you — to the extent it can transfer them — the rights it may hold in Outputs generated through your account during that period, so you can use them for lawful commercial purposes. This does not affect material, voices, or rights belonging to third parties, open-source licences, app store rules, or any legal limits on whether Outputs can be copyrighted, registered, protected exclusively, or used commercially.

Free and basic users. If you generate Outputs on a free tier, trial, or unpaid feature, then unless the product page says otherwise you get only a limited, non-exclusive, non-transferable, non-sublicensable licence to use them for personal, non-commercial, educational, testing, or entertainment purposes. If you put such Outputs on social media, in a community, or anywhere public, please make it clear and reasonable that the Content was made with MyMelos or includes MyMelos AI-generated material.

Whatever plan you are on, you may not turn Outputs to anything illegal, infringing, fraudulent, misleading, impersonating, defamatory, non-consensual-deepfake, child-endangering, or maliciously manipulative, or to any other purpose that breaches these Terms.

4.6 Remixing, collaboration, and public content

If you switch on remixing, collaboration, public posting, or community sharing, other people may view, comment on, share, or build derivative works from your public Content. The precise rights and permitted uses depend on the feature you turn on, the notices shown in the interface, and these Terms. You must be entitled to post the Content publicly, and you accept that public Content may be kept, reshared, or referred to by others.

4.7 AI Outputs are not unique and carry no guarantees

You accept that AI results can resemble Content produced for others, public data, everyday styles, plain prompts, or works owned by third parties. BitDynamic makes no promise that any Output is original, unique, copyrightable, registrable, free of infringement, merchantable, or suited to a particular purpose. Before putting Outputs to commercial or public use, you are responsible for checking copyright, trademark, likeness, voice, publicity, privacy, advertising, and other compliance concerns.

5. Rules of Use

You agree that you will not, and will not help anyone else to:

  1. Putting up, creating, sharing, or selling Content that breaches or misuses another party's copyright, trademark, patent, trade secret, likeness, publicity, reputation, privacy, biometric rights, or any other lawful interest;
  2. Copying, mimicking, extracting, synthesising, or passing yourself off as another person's voice, appearance, facial features, identity, or other personal traits without that person's clear permission;
  3. Producing, circulating, or helping to produce child sexual abuse material, intimate content shared without consent, malicious deepfakes, sextortion, harassment, hate, threats of violence, terrorism, human trafficking, drug crime, scams, malware, or any other unlawful or harmful material;
  4. Turning the Service to political deception, fake endorsements, impersonation of public figures or organisations, deceptive marketing, financial scams, identity theft, or anything else capable of deceiving the public;
  5. Disrupting the Service, getting around restrictions, or weakening platform security by means of scripts, bots, crawlers, bulk registrations, credential stuffing, proxy pools, API abuse, or comparable methods;
  6. Carrying out reverse engineering, decompilation, cracking, scanning, probing, or circumvention, or trying to obtain model weights, source code, private interfaces, system prompts, non-public data, or security mechanisms;
  7. Applying Service Outputs, interface behaviour, model responses, or platform data to create, train, assess, tune, or market a rival model, system, or service without our prior written consent;
  8. Introducing viruses, trojans, worms, logic bombs, malicious scripts, abnormal requests, or anything else capable of harming the Service, devices, networks, or data security;
  9. Working around regional limits, risk controls, billing systems, content-safety systems, or minor-protection measures through VPNs, proxies, falsified location data, false identities, payment fraud, age circumvention, or similar tactics; or
  10. Contravening any applicable law, regulation, platform rule, these Terms, or other reasonable-use policies we publish.

5.1 Copyright complaints and DMCA notices

BitDynamic respects intellectual property. If you believe that Content shown, hosted, generated, posted, linked, or distributed through the Service infringes a copyright you own or are authorised to represent, you may send us a copyright complaint or DMCA notice at service@bitdynamic.co. Please use “Copyright Complaint” or “DMCA Notice” as the email subject.

To help us review your request, please include as much of the following as you can:

  1. The name, email address, and other necessary contact details of the rights holder or authorised agent;
  2. A physical or electronic signature of the rights holder or authorised agent;
  3. A clear description of the work you say has been infringed — if your notice covers several works, a representative list is fine;
  4. Enough detail for us to find the allegedly infringing Content, such as a URL, user ID, work ID, file ID, timestamp, or page path;
  5. A statement that you believe in good faith that the disputed use is not authorised by the rights holder, its agent, or the law; and
  6. A statement that your notice is accurate and that you are the rights holder or are authorised to act for them — made under penalty of perjury where the law requires it.

Once we receive a reasonably complete complaint, we may, as the law allows, remove the Content, disable access, restrict distribution, ask for more information, notify the relevant user, keep records, or take other appropriate action. We may also forward the necessary parts of the complaint to the user who posted or generated the Content, so they can understand it and respond lawfully.

If your Content was removed or disabled and you believe the action was a mistake, a misidentification, or was covered by authorisation, fair use, or another lawful basis, you may send a counter-notice to service@bitdynamic.co. A counter-notice should include your identity and contact details, the location of the removed or disabled Content, an explanation of why you believe the action was wrong, your signature, and any other statements the law requires — including, where necessary, a statement that you accept service of legal process from the complainant or its agent.

As the law allows, we may restrict, suspend, or terminate accounts that repeatedly or seriously infringe intellectual property rights. Please do not file false, malicious, misleading, or abusive complaints, notices, or counter-notices. Whoever files a false or abusive notice is responsible for the resulting liability.

6. Payment, Renewals, and Refunds

6.1 Paid features and taxes

Some features — extra generation credits, high-definition rendering, voice cloning, commercial-use rights, more storage, or advanced tools — require payment. The price, billing period, benefits, taxes, renewal terms, and cancellation method are shown on the purchase, store, or checkout page. Please keep your payment details accurate, valid, and lawfully authorised.

6.2 Automatic renewal

Monthly, quarterly, annual, and other recurring subscriptions renew automatically at the end of each billing period unless you cancel through the required channel before that period ends. Renewal is charged at the then-current price, or the price you were previously told about, plus applicable taxes.

For subscriptions bought through the Apple App Store or Google Play, cancellation, refunds, renewals, and billing are usually managed by that store. Cancel through your Apple ID, Google Play, or the platform's subscription-management page at least 24 hours before the current period ends — or earlier, if the platform's rules require it. For subscriptions bought through the web via Stripe, PayPal, or another processor, you can cancel in your account settings, through the web subscription-management portal, via a link from the processor, or through our support process.

6.3 Payments handled by others

BitDynamic does not directly collect or store complete card numbers, debit or credit card numbers, bank account details, or PayPal logins. Web payments, subscriptions, invoices, refunds, chargebacks, and payment risk controls may be handled by Stripe, PayPal, or other processors, while in-app purchases may be handled by the Apple App Store or Google Play. Those processes are governed by the relevant third party's own terms, privacy policy, refund rules, dispute procedures, and risk controls.

We may receive limited information from Stripe, PayPal, Apple, Google, or other processors that we need to run the Service — such as order numbers, payment confirmations, subscription status, customer or subscription IDs, payment tokens, billing email and country, invoice, refund and chargeback status, tax details, and anti-fraud outcomes. Those processors may also separately handle some payment information for their own compliance, risk-control, anti-money-laundering, sanctions-screening, tax, accounting, dispute-resolution, and security purposes.

6.4 Price changes

We may change prices to reflect service costs, model-compute costs, market conditions, or product changes. Where the law or platform rules require advance notice for existing subscribers, we will give it — through in-app messages, email, store mechanisms, or another reasonable channel — before a new price takes effect. If you do not agree to a change, you may cancel before it applies.

6.5 Refunds and instant delivery

Unless the purchase page, store rules, applicable law, or a separate written commitment from us says otherwise, used generation credits, delivered digital content, voice-cloning services that have already begun, and Outputs already downloaded or posted publicly are generally non-refundable.

Nothing in these Terms reduces any refund, withdrawal, cancellation, or other consumer remedy that cannot be waived under the consumer-protection laws or store rules that apply where you live. Send refund, withdrawal, or cancellation requests through the relevant purchase channel, store, or processor, or through our support process.

7. Disclaimers

To the fullest extent the law allows, the Service, our models, software, Content, Outputs, voice models, community features, and third-party integrations are provided “as is” and “as available.” BitDynamic and its affiliates, officers, employees, suppliers, and licensors disclaim all express, implied, and statutory warranties — including any warranty of merchantability, fitness for a particular purpose, uninterrupted availability, accuracy, completeness, reliability, freedom from errors or viruses, freedom from infringement, copyrightability, registrability, exclusivity, or commercial success.

You accept that AI Outputs may be wrong, incomplete, inaccurate, similar to other content, unavailable, biased, or unsuitable for commercial use. Outputs are not legal, medical, financial, investment, professional, fact-checking, or other expert advice. You decide whether and how to use any Output, and you are responsible for publishing, commercialising, or otherwise using it.

Third-party platforms, app stores, payment processors, cookie and analytics providers, cloud services, community platforms, and other integrations are controlled by their own providers. Beyond what the law requires, we are not responsible for their availability, accuracy, security, fees, rule changes, or data processing.

8. Limits on Our Liability

To the fullest extent the law allows, BitDynamic and its affiliates, directors, officers, employees, suppliers, and licensors are not liable for any indirect, incidental, special, punitive, exemplary, or consequential damages arising from or relating to your use of, or inability to use, the Service, Outputs, your account, a subscription, data, third-party services, or these Terms. This covers lost profits, lost revenue, lost goodwill, data loss, business interruption, the cost of substitute services, and reputational harm, even if we were told such damages were possible.

To the fullest extent the law allows, our total cumulative liability arising from the Service or these Terms will not exceed the amount you actually paid us for the Service in the six months before the event that gave rise to the claim. If you have paid us nothing, our total liability will not exceed USD 100 or the minimum the law allows. Some jurisdictions do not permit certain liability limits, so these apply only as far as the law allows.

9. Your Responsibility to Us

To the extent the law allows, if a third party brings a claim, complaint, investigation, action, loss, fine, liability, cost, or expense against BitDynamic, its affiliates, officers, employees, contractors, licensors, or suppliers arising from any of the following, you agree to defend, indemnify, and hold us harmless:

  1. Your Inputs, Outputs, voice models, publicly posted Content, or commercial use of Content;
  2. Your breach of these Terms, applicable law, third-party rights, or platform rules;
  3. Your unauthorised use of another person's voice, likeness, work, trademark, personal data, biometric information, or other protected interest; or
  4. Your fraud, account farming, malicious automation, payment violation, security attack, or other misconduct.

Where it is reasonably practicable, we will tell you about the relevant claim, and we may choose to take over its defence and settlement. You may not settle a matter in a way that admits fault by us, adds to our obligations, or harms our rights without our prior written consent.

10. Suspension, Termination, and Data

If we reasonably believe there is a breach of these Terms, unlawful Content, fraud, payment risk, risk to a minor, a security threat, a regulatory requirement, a service shutdown, or another necessary reason, we may limit features, suspend accounts, remove Content, freeze credits, cancel subscription access, decline service, or terminate accounts. Where it is reasonably possible, we will give notice or an appeal route — except where emergency safety, a legal ban, anti-fraud, child-safety, infringement, or regulatory needs make that impracticable.

Once your account ends, your right to access the Service ends too. Provisions that by their nature should survive — such as those on intellectual property, Content licences, AI training limits, fee settlement, disclaimers, liability limits, indemnification, disputes, data retention, and legal compliance — continue to apply.

The deletion, retention, and anonymisation of accounts, Content, and personal data are governed by our Privacy Policy. We may keep limited information for as long as necessary for legal duties, disputes, security audits, anti-fraud, minor protection, accounting records, or backup cycles.

11. Export Controls, Severability, and Other Matters

The software, models, algorithms, data flows, encryption technology, and related technology made available through the Service may be subject to export-control, sanctions, trade-compliance, anti-money-laundering, and similar laws. You may not download, access, export, re-export, transfer, or use the Service in breach of applicable law.

If a competent authority finds any provision of these Terms invalid, unlawful, or unenforceable, that provision will be changed or removed only as far as necessary, and the rest of these Terms will stay in force.

These Terms, together with the Privacy Policy, our purchase pages, subscription confirmations, and any rules expressly incorporated into the app, are the whole agreement between you and BitDynamic about the Service, and they replace any earlier understanding on the same subject, whether spoken or written.

You may not assign your rights or duties under these Terms without our prior written consent. We may assign ours in connection with a merger, acquisition, reorganisation, asset transfer, business adjustment, or other circumstance the law permits, and we will give notice where the law requires it.
