Terms of Service

Last updated: October 10, 2026　Effective date: October 10, 2026

1. Definitions

• "Application" means the Sublyric subtitle software provided by ShineSoft (Guangzhou Shi'er Software Technology Co., Ltd. ("ShineSoft," "we," "us," or the "Company")), including the Free Version and the Paid Features;
• "Free Version" means the Application without activation, which allows you to edit subtitles, save project files, and export subtitle and lyric files;
• "Paid Features" means the features unlocked by activation, namely AI speech recognition, AI translation, and video export;
• "License" means the right to use the Paid Features granted to you upon purchase, in accordance with these Terms;
• "Order" means your request, placed through Paddle, to purchase a License from us;
• "You" means the individual using the Application, or the organization on whose behalf they are doing so.

2. Acknowledgment

These Terms of Service form a legally binding agreement between you and us. By downloading, installing, activating, or using the Application, you agree to be bound by these Terms, as well as by our Refund Policy and Privacy Policy, which are incorporated by reference and together with these Terms form the entire agreement between you and us.

Important: Sections 7 and 8 limit our liability and affect your rights. Please read them carefully. By ticking the acceptance box at checkout or in the installer, or by acknowledging the notice in the Application, you confirm that you have read and accepted these Terms.

These Terms apply to your use of the Application, and to Licenses purchased through Paddle on our international website. If you purchased a License through our Chinese-language website using Alipay or WeChat Pay, our Chinese-language Terms of Service apply instead.

3. Availability, Merchant of Record and Payment

The Application can be downloaded free of charge from our website or the Microsoft Store. Licenses are sold only through our website.

Order processing, payment collection, and invoicing are handled on our behalf by Paddle.com Market Ltd ("Paddle") as the Merchant of Record. Your payment information is collected and processed by Paddle under Paddle's terms and Privacy Policy; we never access or store it.

Microsoft is not a party to these Terms and is not responsible for the Application, Licenses, or refunds.

4. License Grant and Activation Codes

Subject to payment of applicable fees and your compliance with these Terms, we grant you a non-exclusive, non-transferable, personal license to activate and use the Application, including the Paid Features, on one (1) device using one activation code ("one device, one code").

Device migration: each License supports up to five (5) device changes, with at least three (3) calendar days between changes. Upon migration, the authorization on the original device is deactivated and, as a rule, cannot be restored to that device. If you need to exceed these limits for reasons beyond your control, such as device failure or loss, please contact support — we will complete a manual review and respond within seven (7) business days. Where a License is switched between devices unusually frequently or shows other signs of abnormal use, we may review and delay or decline a migration request.

Restrictions. You may not:

• sell, rent, transfer, share, publish, or otherwise make your activation code available to any third party ("share" means providing your activation code for use on a device or by a person other than you);
• reverse-engineer, decompile, or crack the Application, or attempt to obtain its source code;
• circumvent or tamper with the license verification mechanism;
• remove or obscure any copyright notice in the Application; or
• use automated means to abuse the Service.

Violations of this Section are handled in accordance with Section 12 (Termination).

5. Intellectual Property

The Application and all of its content (code, interface, design, icons, algorithms, documentation, etc.) are owned by us or our licensors. You receive only the license expressly granted in these Terms and no ownership rights in the Application.

Subtitles, translations, and other output you create with the Application belong to you or the relevant original rights holder. Third-party components and models used by the Application remain the property of their respective owners.

6. Acceptable Use (AI Processing)

6.1 Local and third-party processing. Speech recognition (transcription) is performed entirely on your device and does not upload your audio or video files to any server. Subtitle translation requires you to select and connect a third-party translation service (such as DeepSeek, using your own API key, Google Translate, or MyMemory). After you consent in the Application, the subtitle text you select is sent directly from your device to that provider for processing (see Section 4 of our Privacy Policy). We do not retain, review, or otherwise access the content you process.

6.2 Prohibited content. You agree not to use the Application to generate, process, or distribute content that violates applicable law, including without limitation non-consensual intimate content, hate speech, harassment or defamation directed at a specific person or group, content involving the sexual exploitation of minors, or content intended to facilitate malware or cyberattacks.

6.3 Your responsibility. You are solely responsible for the audio, video, and text content you process using the Application, including ensuring you hold all rights necessary to process that content, and for your own use of the resulting subtitles or translations. You may not use content generated by the Application to infringe the copyright, publicity rights, privacy, or other lawful rights of any third party.

If you breach Section 6.2 or 6.3, we may suspend or terminate your License, without liability to you.

6.4 Feedback on AI output. The AI features of the Application (including models running locally and third-party translation services) may produce inappropriate, unlawful, or clearly incorrect content; please review all output before you use it. If you encounter such content, you can report it to team@shinesoft.cn, including the relevant text excerpt and the feature or translation engine you used. We do not access content on your device and only handle the materials you choose to send us. We will reply within fifteen (15) business days and, where appropriate, provide usage guidance or improve the relevant features in future versions.

7. Disclaimer and AI Output Notice

To the maximum extent permitted by law, the Application is provided "AS IS" and "AS AVAILABLE," without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose, or uninterrupted operation. We do not warrant that the Application will be error-free, uninterrupted, compatible with your other software or hardware, or that we will continue to provide updates, upgrades, or technical support for it.

The Application includes AI-based subtitle recognition and generation features. You understand and agree that:

• Any stated subtitle-recognition accuracy rate is calculated as character accuracy under standard test conditions, and does not account for punctuation, speaker separation, or timestamp alignment;
• Real-world recognition results may vary depending on factors such as audio quality, accent, background noise, technical terminology, and language;
• We do not guarantee the accuracy, completeness, or fitness of the output for any particular purpose, and you are responsible for evaluating and using the output at your own discretion.

Third-party translation services. When you use a third-party translation service, you must comply with that provider's terms and are responsible for any fees it charges (such as DeepSeek API usage fees). Translation results are generated by the third-party service, and their availability, speed, and accuracy depend on that service. We make no warranty regarding the interruption, change, or discontinuation of any third-party service, or the accuracy of its translations. Your subtitle text is processed by your chosen provider under its own terms and privacy policy. Note that MyMemory is a public translation memory: text you submit may be added to its public corpus. If you do not want your content to become public, do not use MyMemory.

8. Limitation of Liability

8.1 To the maximum extent permitted by law, we will not be liable for any indirect, incidental, special, or consequential damages, including lost profits, data loss, business interruption, or loss of goodwill, arising from your use of or inability to use the Application.

8.2 For users who have purchased a License, our total liability to you will not exceed the amount you actually paid for the License giving rise to the claim.

8.3 The Free Version is provided free of charge. To the maximum extent permitted by law, we are not liable for any damages arising from your use of or inability to use the Free Version.

8.4 Nothing in these Terms excludes or limits our liability for fraud, intentional misconduct, gross negligence, death or personal injury caused by our negligence, or any other liability that cannot be excluded or limited under applicable law. Some jurisdictions do not allow the exclusion or limitation of certain damages, so the above limitations may not fully apply to you.

8.5 Please back up your important data. We are not responsible for data loss or corruption caused by user error, device failure, system incompatibility, or third-party services.

9. Software Updates

We may release updates to the Application from time to time (including feature improvements, bug fixes, and security patches), and may do so without notifying each user individually. Updates are available through our website. We recommend keeping the Application up to date for the best experience and security.

10. Export Compliance

You must comply with all applicable export and import laws and regulations, and may not use the Application for any purpose or in any region prohibited by law.

11. Right of Withdrawal and Refunds

Your right to a refund, and any applicable statutory right of withdrawal, is governed exclusively by our Refund Policy, which forms part of these Terms. If you are a consumer in the EU, UK, or a similar jurisdiction that grants a right of withdrawal for digital content, the specific rules are set out in the Refund Policy.

12. Termination

12.1 If you breach these Terms, we may, depending on the severity of the breach, suspend or terminate the relevant activation code, in which case you will no longer be able to use the Paid Features.

12.2 After an activation code is terminated, you may continue to use the Free Version, but you may not regain access to the Paid Features by cracking the Application, circumventing license verification, using another person's activation code, or similar means.

12.3 If you commit a serious breach — including, without limitation, cracking the Application, distributing unlawful content, attacking our services, or infringing the lawful rights of others — we may terminate all of your rights to use the Application, including the Free Version.

12.4 Upon termination, you must stop using the terminated features and delete or uninstall the relevant copies. We reserve the right to seek compensation from you for any losses caused by your breach.

13. Governing Law and Dispute Resolution

These Terms are governed by the laws of the People's Republic of China, without regard to conflict-of-laws principles.

Any dispute arising out of or in connection with these Terms shall first be resolved through good-faith negotiation. Failing that, the dispute shall be submitted to the Shenzhen Court of International Arbitration ("SCIA") for arbitration in accordance with its arbitration rules in effect at the time of the arbitration application. The seat of arbitration is Shenzhen, the language of arbitration is English, and the arbitral award is final and binding on both parties.

If you are a consumer, this clause does not affect the protections and remedies you are entitled to under the mandatory laws of your place of residence. Where local law prohibits referring consumer disputes to arbitration, or requires such disputes to be heard by a specific court, that mandatory local law will prevail.

14. Changes to These Terms

We may modify these Terms from time to time, and will give advance notice of material changes via a website announcement. If you do not agree to the changes, you may stop using the Application. Continued use of the Application after a change takes effect constitutes acceptance of the revised Terms.

Unless mandatory law provides otherwise, an activation code purchased but not yet activated before a change takes effect remains subject to the version of these Terms in force at the time of purchase; purchases or activations made after the change takes effect are subject to the revised Terms.

15. Severability

If any provision of these Terms is held invalid or unenforceable, the remaining provisions remain in full force and effect.
