TERMS OF USE

Effective date: August 6, 2026

Welcome to Solo.

These Terms of Use ("Terms") are a legally binding agreement between you and the individual developer operating Solo ("Solo," "we," "us," or "our"). These Terms govern your access to and use of the Solo mobile application, websites, software, artificial intelligence music generation tools, and related products and services (collectively, the "Services").

Solo allows users to create AI-generated songs, instrumentals, lyrics, vocals, cover artwork, and other music-related content using text prompts, lyrics, audio files, voice samples, musical preferences, reference materials, and other supported inputs.

By creating an account, purchasing a subscription or credits, accessing the Services, or otherwise using Solo, you confirm that you have read, understood, and agreed to these Terms and our Privacy Policy.

If you do not agree to these Terms, you must not access or use the Services.

1. ELIGIBILITY

You may use Solo only if you are legally capable of entering into a binding agreement under the laws applicable to you.

In the United States, users under the age of 13 may not use the Services without legally valid permission from a parent or legal guardian. In other countries or regions, the applicable minimum age may be different.

Where local law requires parental or guardian consent, you may use the Services only after obtaining that consent.

Paid features may only be purchased by users who are legally permitted to make purchases or whose purchases have been authorized by a parent or legal guardian.

You may not use Solo if your account was previously suspended or terminated for violating these Terms, unless we expressly authorize you to create a new account.

2. ACCOUNTS AND REGISTRATION

Some features may be available without registration. You may need to create an account to access generation history, subscriptions, purchased credits, downloads, publishing, synchronization, or other functions.

Account information. You agree to provide true, accurate, current, and complete information when creating or updating your account.

Third-party sign-in. You may be able to register or sign in through Apple, Google, or another third-party provider. Your use of that provider is also governed by its own terms and privacy policy.

Account security. You are responsible for maintaining the confidentiality of your login credentials and for all activity conducted through your account.

You must not sell, rent, transfer, share, or provide your account to another person without our permission.

You must notify us immediately at support@soloaisong.com if you believe your account has been accessed without authorization or your credentials have been lost or compromised.

We may require you to verify your identity or account ownership before restoring access, processing an account request, or responding to a security incident.

3. LICENSE TO USE SOLO

Subject to your continued compliance with these Terms, Solo grants you a limited, revocable, non-exclusive, non-transferable, and non-sublicensable license to access and use the Services for lawful purposes.

This license does not transfer ownership of Solo, its software, models, algorithms, designs, databases, trademarks, content, or other intellectual property to you.

Except where expressly permitted by Solo or required by applicable law, you may not copy, modify, distribute, sell, lease, sublicense, reverse engineer, decompile, disassemble, extract source code from, or create competing services using any part of the Services.

We reserve all rights not expressly granted under these Terms.

4. SUBSCRIPTIONS, CREDITS, AND PAYMENTS

Solo may offer free features, paid subscriptions, consumable credits, promotional benefits, or other paid products. Available plans, prices, benefits, usage limits, and restrictions will be displayed in the application or on the relevant purchase page.

Payment authorization. By completing a purchase, you authorize Apple, Google, Stripe, or another applicable payment provider to charge the selected payment method for the displayed price, including applicable taxes and fees.

Credits. Credits are digital service units that may be used for eligible Solo features. Credits are not legal currency, stored value, electronic money, or property. Except where required by law, credits cannot be transferred, exchanged for cash, resold, or used outside Solo.

Different generation functions may consume different amounts of credits. The required credit amount may be displayed before or when you initiate a generation request.

Promotional or complimentary credits may be subject to separate conditions or expiration periods. Purchased credits do not expire unless an expiration period is clearly disclosed at the time of purchase or permitted by applicable law.

Price changes. We may change prices, credit requirements, subscription benefits, or available plans. Changes will not affect completed purchases unless required by law. Where required, we will provide reasonable notice before a subscription price change becomes effective.

5. AUTOMATICALLY RENEWING SUBSCRIPTIONS

Some Solo subscriptions renew automatically.

By purchasing an automatically renewing subscription, you authorize the applicable payment provider to charge the subscription fee at the beginning of each renewal period unless you cancel before renewal.

Your subscription will normally renew for the same billing period selected during purchase, such as weekly, monthly, quarterly, or yearly, unless otherwise disclosed.

You can manage or cancel your subscription through the platform used to make the purchase:

• Apple App Store subscriptions must be managed through your Apple ID subscription settings;
• Google Play subscriptions must be managed through your Google Play subscription settings;
• subscriptions purchased through another payment provider must be managed through that provider or the available Solo account controls.

To avoid the next renewal charge, you should cancel at least 24 hours before the current subscription period ends, or within any other deadline displayed by the applicable payment provider.

Deleting the Solo application or deleting your Solo account does not automatically cancel an App Store, Google Play, or third-party subscription. You must cancel the subscription through the applicable payment platform.

After cancellation, you may continue using subscription benefits until the end of the paid billing period unless otherwise stated by the payment provider.

6. REFUNDS

Except where required by applicable law, purchases are final and non-refundable after the relevant digital benefits, credits, or services have been delivered or used.

Refund requests for purchases completed through the Apple App Store must be submitted directly to Apple and are subject to Apple's refund rules.

Refund requests for purchases completed through Google Play must be submitted to Google or handled according to Google Play's applicable policies.

Refund requests for purchases made through another payment provider may be submitted to that provider or to support@soloaisong.com, depending on the payment method.

Canceling a subscription stops future renewal charges but does not automatically provide a refund for the current billing period.

Unused portions of subscriptions and partially used credit packages are not refundable unless required by applicable law or expressly approved by Solo.

7. USER INPUT AND USER CONTENT

"User Content" means content or materials that you upload, submit, enter, publish, transmit, or otherwise provide through Solo, including:

• text prompts and song descriptions;
• lyrics, titles, tags, and creative instructions;
• audio recordings and music files;
• voice samples and vocal references;
• melodies, compositions, beats, and instrumentals;
• photographs, images, videos, and cover artwork;
• comments, profile information, and public posts;
• feedback and other submitted materials.

You retain any ownership rights that you legally hold in your original User Content.

You represent and warrant that:

• you own the User Content or have all necessary licenses, permissions, authorizations, and consents to use it;
• your User Content does not infringe copyright, trademark, publicity, personality, privacy, contract, or other rights;
• you have permission from every identifiable person whose voice, image, likeness, performance, or personal information is included;
• Solo will not be required to obtain additional permissions or pay royalties, fees, compensation, or attribution to another person because of your use of the User Content;
• uploading or using the User Content does not violate any agreement between you and another person.

You are solely responsible for your User Content and any consequences arising from uploading, processing, publishing, distributing, or commercially using it.

8. LICENSE TO PROCESS USER CONTENT

To operate the Services, you grant Solo and our service providers a worldwide, non-exclusive, royalty-free, transferable, and sublicensable license to host, store, reproduce, process, modify, adapt, transmit, and display your User Content to the extent reasonably necessary to:

• process your generation requests;
• create and deliver generated content;
• store and synchronize your projects;
• provide sharing, publishing, and download features;
• operate, maintain, secure, and improve the Services;
• investigate misuse, fraud, infringement, or security incidents;
• comply with legal obligations and enforce these Terms.

When you intentionally publish User Content or generated content publicly, you also grant Solo permission to display, reproduce, distribute, stream, communicate, and make that public content available through the Services.

This license continues only for as long as reasonably necessary to provide the Services, comply with legal obligations, resolve disputes, maintain backups, and protect Solo and its users.

You should not upload confidential information, trade secrets, or proprietary materials unless you understand and accept that they must be processed to provide the requested feature.

9. AI-GENERATED OUTPUT

"Output" means songs, music, instrumentals, vocals, lyrics, cover artwork, and other content generated through Solo in response to your instructions and User Content.

Paid users. Subject to these Terms, applicable law, third-party rights, and limitations displayed at the time of purchase, users who generate Output using a paid subscription or purchased credits may use that Output for personal or commercial purposes.

Free users. Output created using a free plan, free credits, trial benefits, or promotional access may be restricted to personal and non-commercial use unless Solo expressly states otherwise.

Solo may require attribution for Output created through a free plan. Any attribution requirement will be displayed in the applicable feature, plan, or purchase description.

These Terms do not grant you ownership of:

• third-party content contained in or used as part of your User Content;
• Solo's software, models, algorithms, templates, interfaces, trademarks, or technology;
• content owned by another user or third party;
• elements that cannot legally be owned or protected.

Your rights in Output are subject to applicable copyright and intellectual property laws. Laws concerning AI-generated content may differ by country and may change over time.

10. AI OUTPUT LIMITATIONS

Artificial intelligence systems are probabilistic and may produce unexpected, incomplete, inaccurate, or similar results.

Solo does not guarantee that:

• any Output will be unique;
• another user will not receive identical or similar content;
• Output will qualify for copyright registration;
• Output will be free from all third-party claims;
• Output will be suitable for a particular commercial purpose;
• Output will satisfy the rules of every streaming, publishing, advertising, or distribution platform.

You are responsible for reviewing Output and conducting appropriate legal, copyright, trademark, music clearance, and commercial-use checks before releasing, selling, licensing, distributing, publishing, or relying on it.

Where required by law or platform policy, you are responsible for identifying, labeling, or disclosing that content was generated or modified using artificial intelligence.

11. VOICE AND LIKENESS

Solo may provide features that process voice recordings, vocal references, audio characteristics, images, names, or likenesses.

You may use another person's voice, image, name, or likeness only when you have obtained all permissions required by applicable law.

You must not use Solo to:

• impersonate another person for fraud, deception, harassment, or manipulation;
• create misleading endorsements;
• falsely represent that a public figure or private person created, performed, approved, or supports content;
• create unauthorized voice clones;
• violate privacy, publicity, personality, biometric, or data protection rights;
• deceive listeners about the identity of a performer or speaker.

We may block, remove, or restrict content or accounts where we reasonably believe voice, identity, or likeness rights have been violated.

12. PROHIBITED CONTENT

You may not upload, generate, publish, request, distribute, or promote content that:

• violates any applicable law or regulation;
• infringes copyright, trademark, patent, privacy, publicity, personality, or other legal rights;
• contains unauthorized copyrighted music, recordings, lyrics, samples, voices, artwork, or performances;
• is fraudulent, deceptive, defamatory, libelous, or deliberately misleading;
• impersonates another person or misrepresents the origin of content;

• exposes another person's confidential, private, or personal information without permission;
• contains malware, viruses, spyware, harmful code, or destructive files;
• is otherwise harmful, abusive, offensive, or unsuitable for the Services.

We may use automated systems and human review to detect prohibited content. We do not guarantee that all content will be reviewed before it is generated or published.

13. RESTRICTIONS ON USE

You agree not to, and not to help another person to:

• interfere with, disrupt, damage, or overload the Services;
• access non-public systems, servers, accounts, models, or infrastructure;
• bypass security controls, rate limits, access controls, payment systems, or usage restrictions;

14. CONTENT REVIEW AND ENFORCEMENT

We are not obligated to monitor every generation request or item of User Content. However, we may review, filter, block, restrict, disable, or remove content where we reasonably believe it:

• violates these Terms;
• violates applicable law;
• infringes another person's rights;
• creates legal, security, or reputational risk;
• threatens users, Solo, or the public;
• is the subject of a valid complaint or legal request.

We may issue warnings, limit features, suspend generation, remove content, disable sharing, suspend accounts, terminate accounts, preserve evidence, or report suspected unlawful activity to relevant authorities.

We are not responsible for unauthorized copying, downloading, recording, reposting, or use of public content by other users or third parties.

15. INTELLECTUAL PROPERTY

The Services and all materials provided by Solo, excluding User Content, are owned by the individual developer operating Solo or the applicable licensors and may be protected by copyright, trademark, patent, database, trade secret, and other intellectual property laws.

This includes Solo's:

• software and source code;
• artificial intelligence models and algorithms;
• user interface and visual designs;
• logos, names, and trademarks;
• templates, graphics, and documentation;
• databases, compilations, and platform content.

You may not use the Solo name, logo, trademark, branding, or other protected materials without prior permission, except where permitted by law.

16. COPYRIGHT AND INTELLECTUAL PROPERTY COMPLAINTS

Solo respects intellectual property rights.

If you believe that content available through Solo infringes a copyright, trademark, voice right, publicity right, personality right, or other right that you own or are authorized to enforce, send a notice to:

Email: support@soloaisong.com

Your notice should include:

• your full name and contact information;
• identification of the work or right that you claim has been infringed;
• identification or location of the allegedly infringing content;
• an explanation of why you believe the use is unauthorized;
• evidence that you own or are authorized to act for the relevant right;
• a statement that the information in your notice is accurate;
• your physical or electronic signature.

We may provide the complaint to the user who uploaded or generated the challenged content so that the user can respond.

We may remove or restrict access to disputed content while reviewing a complaint. We may suspend or terminate repeat infringers or users involved in serious infringement.

Knowingly submitting a false or misleading complaint may result in legal liability.

17. FEEDBACK

You may voluntarily provide suggestions, ideas, reviews, bug reports, feature requests, comments, or other feedback regarding Solo ("Feedback").

You agree that Feedback is not confidential and that Solo may use, reproduce, modify, develop, publish, distribute, and commercialize Feedback without payment, attribution, or restriction.

Providing Feedback does not give you ownership of any feature, product, improvement, or service developed using that Feedback.

18. THIRD-PARTY SERVICES

Solo may integrate with or link to third-party services, including Apple, Google, payment providers, analytics providers, social networks, messaging applications, streaming platforms, and music distribution services.

We do not control third-party services and are not responsible for their content, availability, security, privacy practices, transactions, or actions.

Your use of a third-party service is governed by that service's own terms, policies, and fees.

You are responsible for reviewing the terms and privacy policies of third-party services before using them.

19. CHANGES TO THE SERVICES

Solo is continually developed and may change over time.

We may add, modify, limit, suspend, replace, or discontinue any feature, model, generation mode, subscription benefit, credit requirement, supported format, or part of the Services.

We do not guarantee that any specific feature or model will always remain available.

We may perform maintenance, updates, security work, or emergency repairs that temporarily interrupt the Services.

Where reasonably practicable, we may provide notice before materially discontinuing a paid feature.

20. TERMINATION AND ACCOUNT SUSPENSION

You may stop using Solo at any time. You may also request account deletion through the application, where available, or by contacting support@soloaisong.com.

We may restrict, suspend, or terminate your account or access to the Services if:

• you violate these Terms;
• your activity creates legal, security, financial, or reputational risk;
• you infringe another person's rights;
• you engage in fraud, chargebacks, payment abuse, or unauthorized use;
• we are required to do so by law, a court, a regulator, or a platform;
• continuing to provide the Services is no longer commercially or technically reasonable.

In serious or urgent cases, suspension or termination may occur without prior notice.

Upon termination, your license to access and use the Services ends immediately. Sections that by their nature should survive termination will remain effective, including provisions concerning ownership, licenses, payment obligations, disclaimers, liability, indemnification, and dispute resolution.

Account termination does not automatically cancel subscriptions managed by Apple, Google, or another third-party payment provider.

21. DISCLAIMER OF WARRANTIES

To the maximum extent permitted by applicable law, the Services are provided on an "as is" and "as available" basis.

Solo makes no warranty, express or implied, regarding:

• continuous, uninterrupted, or error-free availability;
• the accuracy, completeness, uniqueness, originality, or quality of Output;
• whether Output can be copyrighted, registered, licensed, or commercially exploited;
• whether Output is free from third-party rights or claims;
• fitness for a particular purpose;
• merchantability or satisfactory quality;
• compatibility with every device, platform, distributor, or jurisdiction;
• preservation or recovery of User Content or Output.

You use the Services and any Output at your own risk.

Nothing in these Terms excludes warranties or consumer rights that cannot legally be excluded.

22. LIMITATION OF LIABILITY

To the maximum extent permitted by applicable law, the individual developer operating Solo and any applicable licensors, service providers, employees, contractors, and agents will not be liable for indirect, incidental, special, consequential, exemplary, or punitive damages.

This includes loss of profits, revenue, data, business opportunities, goodwill, reputation, anticipated savings, or use arising from:

• your access to or use of the Services;
• your inability to access or use the Services;
• the creation, publication, licensing, sale, or distribution of Output;
• infringement or other third-party claims involving User Content or Output;
• unauthorized access to your account;
• deletion, corruption, or loss of content;
• actions of another user or third-party service.

To the maximum extent permitted by law, Solo's total liability for all claims arising out of or relating to the Services will not exceed the greater of:

• the amount you paid for the Services during the twelve months before the event giving rise to the claim; or
• USD 100.

Some jurisdictions do not allow certain exclusions or limitations of liability. In those jurisdictions, these limitations apply only to the extent permitted by law.

23. INDEMNIFICATION

To the extent permitted by applicable law, you agree to defend, indemnify, and hold harmless the individual developer operating Solo and any applicable licensors, service providers, employees, contractors, and agents from claims, liabilities, damages, losses, and reasonable legal expenses arising from:

• your breach of these Terms;
• your User Content;
• your use, publication, distribution, sale, or licensing of Output;
• your infringement of another person's rights;
• your violation of applicable law;
• your misuse of the Services.

Solo may assume control of the defense of a matter subject to indemnification. You agree to cooperate reasonably with that defense.

24. GOVERNING LAW AND DISPUTE RESOLUTION

These Terms and any dispute arising out of or relating to the Services will be governed by the laws of the People's Republic of China, without regard to conflict-of-law principles.

Mandatory consumer protection rights available in your country or region are not excluded or limited by these Terms.

Before beginning formal legal proceedings, you agree to contact us at support@soloaisong.com and attempt to resolve the dispute informally.

Your notice should include your account information, a description of the dispute, relevant evidence, and the resolution you are requesting.

If the dispute cannot be resolved through reasonable informal discussions, either party may submit the dispute to a court with lawful jurisdiction in the place where the individual developer operating Solo resides, unless mandatory applicable law requires another court or dispute process.

Nothing in these Terms prevents either party from seeking urgent injunctive or protective relief from a court with appropriate jurisdiction.

Where permitted by applicable law, claims must be brought individually and not as part of a class, collective, consolidated, or representative proceeding. This restriction does not apply where prohibited by law.

25. CHANGES TO THESE TERMS

We may update these Terms to reflect changes in the Services, technology, laws, business practices, payment arrangements, or safety requirements.

The updated Terms will be published with a revised effective date.

Where required by law, we will provide additional notice or request your acceptance before material changes take effect.

By continuing to use Solo after updated Terms become effective, you agree to the revised Terms.

If you do not agree to an update, you must stop using the Services and cancel any automatically renewing subscription.

26. NOTICE REGARDING APPLE

If you download or use Solo through the Apple App Store, you acknowledge that these Terms are between you and the individual developer operating Solo, not Apple.

Apple is not responsible for Solo or its content and has no obligation to provide maintenance or support services for Solo.

If Solo fails to conform to an applicable warranty, you may notify Apple, and Apple may refund the purchase price, if any, in accordance with its policies. To the maximum extent permitted by law, Apple has no other warranty obligation regarding Solo.

Apple is not responsible for claims relating to:

• your possession or use of Solo;
• product liability;
• compliance with legal or regulatory requirements;
• consumer protection claims;
• allegations that Solo infringes third-party intellectual property rights.

Apple and its subsidiaries are intended third-party beneficiaries of this section and may enforce it against you.

You must comply with all applicable App Store terms when using Solo.

27. GENERAL TERMS

These Terms, together with our Privacy Policy and any additional terms displayed for a particular feature or purchase, form the entire agreement between you and Solo regarding the Services.

If a provision of these Terms is found unenforceable, the remaining provisions will remain in effect.

Our failure to enforce a provision does not waive our right to enforce it later.

You may not assign or transfer these Terms or your rights under them without prior written permission. Solo may assign these Terms as part of a transfer of the application, intellectual property, or related business assets.

These Terms do not create an employment, partnership, agency, fiduciary, franchise, or joint venture relationship between you and Solo.

Section titles are included for convenience and do not affect interpretation.

If these Terms are translated into another language, the English version will control to the extent permitted by applicable law if there is a conflict between versions.
