Last updated: October 14, 2026 · Effective: October 14, 2026

Operator: Spiral Ladder Technology (Shenzhen) Co., Ltd. (旋梯科技(深圳)有限公司, brand: INNVOX), Shenzhen, Guangdong, China. Email: yaodong@innvox.cn · Phone / WhatsApp: +86 173 8486 0919 · Website: https://innvox.ai/ · These Terms are available in English and Chinese. If the two versions differ, the English version prevails.

1. Agreement

These Terms of Use ("Terms") are an agreement between you and Spiral Ladder Technology (Shenzhen) Co., Ltd. ("we", "us") about your use of the INNVOX mobile app for iPhone and Android (the "App"). By downloading, installing, or using the App, you agree to these Terms and to the INNVOX App Privacy Policy (https://innvox.ai/app/privacy). If you do not agree, do not use the App.

2. License

Subject to these Terms and the rules of the app store you got the App from, we grant you a limited, non-exclusive, non-transferable, revocable license to install and use the App on devices you own or control, for personal, non-commercial voice training.

Except where the law expressly allows it, you may not:

  • copy, modify, rent, sell, or redistribute the App;
  • reverse engineer, decompile, or crack the App, or bypass its security measures;
  • interfere with or attack our servers, or send them data the App would not normally produce;
  • use the App for any unlawful purpose.

3. The Device and Demo Mode

The App is designed for use with the INNVOX Pro voice training device. Without the device, you can explore the App in demo mode, but measurement and training features require the device.

The App can install firmware updates on your INNVOX device. Keep the device charged and near your phone during an update. If an update is interrupted, you may need to run it again.

4. Not a Medical Device; No Medical Advice

The App and the INNVOX device are voice training tools. They are not medical devices, do not diagnose, treat, or prevent any disease or condition, and do not provide medical advice. Measurements, scores, and training suggestions are for voice training reference only and are not a substitute for advice from a doctor, speech-language pathologist, or other qualified professional. If you have concerns about your voice or health, consult a qualified professional.

5. Practice Safely

  • Practice at a comfortable volume and effort, and take breaks.
  • If you feel discomfort, pain, dizziness, or hoarseness, stop and rest. If symptoms continue, consult a qualified professional.
  • Use and clean the INNVOX device as described in the instructions that come with it.
  • Do not use the App while driving or in other situations that need your full attention.

6. Your Data

How we handle information is described in the INNVOX App Privacy Policy. Uploading training data is optional and off by default. If you turn it on, you allow us to store and use the uploaded data for the purposes and periods described in the Privacy Policy. You can turn upload off at any time, or delete uploaded data in Settings > Privacy & security.

7. Updates and Availability

We may update the App and change, add, or discontinue features. Some updates may be required to keep using the App. We do not guarantee that the App or related services (such as firmware downloads) will always be available, uninterrupted, or error-free.

8. Intellectual Property

The App and its software, interface, text, images, audio, and other content are owned by us or our licensors. You receive no rights other than the license expressly granted in these Terms. If you send us feedback or suggestions, we may use them freely without any obligation to you.

9. Disclaimers

To the maximum extent permitted by law, the App is provided "as is" and "as available", without warranties of any kind, express or implied, including warranties of merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that measurements will be accurate or error-free. Hardware warranty and returns for the INNVOX device are governed by the terms that apply to your purchase of the device. Some jurisdictions do not allow the exclusion of certain warranties, so some of these exclusions may not apply to you.

10. Limitation of Liability

To the maximum extent permitted by law, we are not liable for any indirect, incidental, special, consequential, or punitive damages, or for any loss of profits or data, arising out of or related to your use of, or inability to use, the App. To the maximum extent permitted by law, our total liability for all claims relating to the App is limited to the greater of the amount you paid for the App (if any) and USD 50.

Nothing in these Terms limits or excludes liability that cannot be limited or excluded by law, such as liability for death or personal injury caused by our negligence, or for fraud.

11. Termination

You may stop using and uninstall the App at any time. If you breach these Terms, we may suspend or end your license to use the App. Sections that by their nature should survive termination (such as intellectual property, disclaimers, limitation of liability, and governing law) will survive.

12. Governing Law and Disputes

These Terms are governed by the laws of the People's Republic of China. Disputes arising from these Terms should first be resolved through friendly negotiation; failing that, they shall be submitted to the competent people's court at our place of business.

This section does not take away the protection given to you by mandatory consumer protection laws of the country, state, or province where you live, which continue to apply where they cannot be excluded by agreement. If you are a consumer in the United Kingdom, nothing in these Terms affects your statutory rights under UK consumer law, such as the Consumer Rights Act 2015.

13. Additional Terms for Apps Downloaded from the Apple App Store

If you downloaded the App from the Apple App Store, the following terms also apply:

  • These Terms are between you and us only, and not with Apple Inc. ("Apple"). We, not Apple, are solely responsible for the App and its content.
  • The license in section 2 is limited to use of the App on Apple-branded products that you own or control, as permitted by the Usage Rules in the Apple Media Services Terms and Conditions, including use through Family Sharing.
  • Apple has no obligation to provide any maintenance or support services for the App.
  • If the App fails to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price of the App (if any) to you. To the maximum extent permitted by law, Apple has no other warranty obligation with respect to the App, and any other claims, losses, liabilities, damages, costs, or expenses attributable to any failure to conform to any warranty are our responsibility under these Terms.
  • We, not Apple, are responsible for addressing any claims by you or any third party relating to the App or your possession and use of the App, including product liability claims, claims that the App fails to conform to any applicable legal or regulatory requirement, and claims arising under consumer protection, privacy, or similar legislation.
  • If a third party claims that the App or your possession and use of the App infringes that third party's intellectual property rights, we, not Apple, are solely responsible for the investigation, defense, settlement, and discharge of that claim.
  • You represent and warrant that you are not located in a country that is subject to a US Government embargo or that has been designated by the US Government as a "terrorist supporting" country, and that you are not listed on any US Government list of prohibited or restricted parties.
  • You must comply with applicable third-party terms of agreement when using the App, such as your wireless data service agreement.
  • Apple and Apple's subsidiaries are third-party beneficiaries of these Terms. Upon your acceptance of these Terms, Apple will have the right (and will be deemed to have accepted the right) to enforce these Terms against you as a third-party beneficiary.

14. Apps Downloaded from Google Play

If you downloaded the App from Google Play, the Google Play Terms of Service also apply to your use of Google Play. Google is not a party to these Terms and is not responsible for the App.

15. Changes to These Terms

We may update these Terms. We will post the new version on this page with a new effective date, and tell you in the App about material changes. If you continue to use the App after the changes take effect, you accept the updated Terms.
