Preamble

Welcome to the Yunwang Innovation application (hereinafter the “Software”) and the companion smart automatic foam roller device (hereinafter the “Smart Device”). This Agreement is entered into by and between you (hereinafter the “User”) and Yunwang Innovation Intelligence (Shenzhen) Co., Ltd. (hereinafter “we”, “us”, or “Yunwang Innovation”) regarding the download, installation, and use of the Software and related services.

[IMPORTANT NOTICE] Before registering for or using the Services, please carefully read and fully understand this Agreement, especially the disclaimers, limitation of liability clauses, and governing law and dispute resolution clauses (such clauses are usually highlighted in bold for your attention). If you are a minor under the laws of the jurisdiction where you reside, please read this Agreement accompanied by your legal guardian.

Unless you have fully read, completely understood, and accepted all terms of this Agreement, please do not use Yunwang Innovation services. When you fill in information as prompted on the registration page, read and agree to this Agreement, and complete all registration procedures, you represent that you have fully read, understood, and accepted all contents of this Agreement, and agree to be bound as a party to this Agreement and other agreements and rules related to Yunwang Innovation services (including but not limited to the Privacy Policy), thereby becoming a Yunwang Innovation “User”.

This Agreement also includes the Privacy Policy and all rules, announcements, or notices that we have published or may publish in the future. When you use a particular product or service of ours, there may be separate agreements and related service rules. Once published, the foregoing rules, announcements, notices, and agreements constitute an integral part of this Agreement, and you shall likewise comply with them. If you do not agree to the terms of this Agreement, you shall immediately stop registration/activation and stop using our related products and services.

If you have not applied for the registration process, or if you became a registered user of the Yunwang Innovation platform and/or Software before this Agreement took effect, your access to and/or use of Yunwang Innovation services shall be deemed as your agreement to accept all contents of this Agreement.

Basic offline massage functions without an account do not require acceptance of this Agreement; account login, cloud sync, Yunwang AI smart plans, and other connected value-added features may only be used after the User has fully read and confirmed acceptance of this Agreement and the Privacy Policy. Yunwang Innovation is entitled, as needed for the Yunwang Innovation Software and related services or operations, to arrange or designate its affiliates, controlling companies, successor companies, or third-party companies recognized by Yunwang Innovation to provide services to you.

Except as expressly provided in this Agreement, for products and services developed/published by us, we are entitled to further regulate them on the basis of this Agreement through separate product and service agreements (hereinafter “Individual Product Agreements”). Users must separately review and confirm such agreements when using the relevant products or services. Where an Individual Product Agreement conflicts with this Agreement, the Individual Product Agreement shall prevail. Use of such product or service by the User shall be deemed acceptance of the relevant Individual Product Agreement.

1. Account Registration and Use

1.1 Account Eligibility

You confirm that when you begin to register for, log in to, and actually use our platform services, you shall be a natural person, legal person, or other organization with full capacity for civil rights and full capacity for civil conduct. If you do not possess the foregoing legal capacity, you and your guardian shall bear all consequences arising therefrom in accordance with applicable laws and regulations.

1.2 Account Description

After you fill in information as prompted on the registration page, read and agree to this Agreement, and complete all registration procedures, you may obtain a platform account with us and become a user of our platform.

You are entitled to log in to our platform using the membership name, email address, or mobile phone number you set or confirmed on our platform (hereinafter the “Account Name”) and the password you set (the Account Name and password collectively the “Account”), or via third-party accounts (including Apple ID, Facebook account, Google account, and WeChat account). The same Yunwang Innovation account works across all companion software and hardware services; the actual login entry points are subject to the version published on the client stores.

Because a user account is associated with user information, you may transfer an account only where expressly provided by laws and regulations, by judicial ruling, or with our consent, and in accordance with the account transfer procedures set out in our platform rules. Once your account is transferred, the rights and obligations under that account are transferred together. Except as above, your account may not be transferred in any manner; otherwise, you shall bear all liabilities arising therefrom.

If you resell, gift, or discard a Smart Device, you must first clear all usage data stored locally on the device via the factory reset function and unbind the device in the App to avoid disclosure of personal information. The quality, safety, and legality of second-hand devices are the sole responsibility of the parties to the transaction.

1.3 Protection of Minors

We attach great importance to the protection of minors’ personal information. When filling in personal information, minor users should strengthen their personal protection awareness and exercise caution, and should correctly use our products and related services with the consent of and under the guidance of their guardians.

Mainland China market: If you are a minor who has reached the age of 14 but not yet 18, before using Yunwang and related services, you should read and agree to this Agreement together under the guardianship and guidance of your parents or other guardians. Under applicable law, minors under 14 years of age are prohibited from independently registering an account; the minor’s parents or other guardians shall read and agree to the Children’s Privacy Protection Statement.

United States market: The Services are not directed to Children under 13. If we discover that we have collected personal information from a child under 13 without verifiable parental consent, we will delete such information.

Other jurisdictions shall follow the local statutory minimum age of consent. Natural persons below the statutory age are prohibited from independently registering an account, logging into the cloud, or using Yunwang AI smart features, and are prohibited from uploading any personal materials including text, health information, voice, photos, or videos.

Minors may only use the device’s basic offline, account-free massage functions under the continuous on-site supervision of a guardian. Before use, the guardian must fully read the device safety instructions, assess the child’s physical tolerance in advance, reasonably select massage areas and intensity, and immediately stop the device if pain, numbness, dizziness, or other discomfort occurs.

If we verify that a minor has registered without guardian authorization or uploaded sensitive information, we are entitled to restrict all connected functions of the account, require guardian identity verification, or directly cancel the account, and concurrently delete the stored personal information of the minor.

2. User Personal Information Protection and Network Security

Protecting users’ personal information is a fundamental principle of Yunwang Innovation. You acknowledge, understand, and agree that in the course of providing our services, processing of users’ personal information may be involved. Yunwang Innovation will process your personal information in accordance with this Agreement and the Privacy Policy. Where the personal information protection provisions of this Agreement conflict with the Privacy Policy, or where this Agreement does not expressly address personal information protection, the Privacy Policy shall prevail. We hope to clearly explain to you through the Privacy Policy how users’ personal information is processed, and therefore recommend that you read the Privacy Policy in full to help you better protect personal information.

2.1 Truthfulness and Legality

In the course of registering an account or using Yunwang Innovation products and services, you may need to provide certain necessary information. Where national laws and regulations specially so require, you must provide true identity information. If the information you provide is incomplete, you may be unable to use Yunwang Innovation products or services, or may be restricted in use. For detailed rules on processing your personal information, please refer to the Privacy Policy. You shall bear full responsibility for the truthfulness, legality, and validity of your registration information with Yunwang Innovation; you shall not impersonate others; shall not publish any information in another person’s name; and shall not maliciously use a registered account so as to cause other users to mistake your identity; otherwise Yunwang Innovation is entitled to immediately stop providing platform services, reclaim the account, and the User shall solely bear all legal liabilities arising therefrom. If registration information changes, it shall be updated promptly so that we may contact you when necessary.

The account name you set shall not violate Chinese laws and regulations or our platform rules on account name management; otherwise we may suspend or cancel your account name and report to the relevant competent authorities.

You understand and undertake that your account name, avatar, profile, and other registration information shall not contain illegal or undesirable information, and shall not involve impersonation of or association with institutions or public figures. In the course of account registration, you shall comply with the seven baseline requirements regarding laws and regulations, the socialist system, national interests, citizens’ lawful rights and interests, public order, social morality, and information authenticity.

2.2 Updates and Maintenance

You shall promptly update the information you provide. Where the law expressly requires us to verify certain users’ information, we will from time to time inspect and verify your information in accordance with law, and you shall cooperate by providing the most recent, true, and complete information. You shall bear all consequences arising from inaccurate or untrue personal information you provide. If we are unable to contact you using the most recent information you provided, or you fail to provide information as we request in a timely manner, or the information you provide is clearly untrue, you shall bear all losses and adverse consequences thereby caused to yourself, others, and us.

2.3 Account Security Rules

Your account is set and kept by you. We recommend that you carefully safeguard your account credentials and password, avoid overly simple passwords, and ensure that you log out and leave our platform through proper steps at the end of each online session. We assume no liability for loss, forgetting, or theft of a user’s account or password not caused by our platform.

We hereby specially remind you to protect your account and password and never disclose them to others. You are solely responsible for keeping your account and password confidential, and shall be responsible for all activities occurring under your account and password (including but not limited to information disclosure, information publication, online clicks to agree to or submit various rules and agreements, online renewal of agreements, or purchase of services). Yunwang Innovation cannot and will not be responsible for any loss arising from your failure to comply with this clause. If you discover any unauthorized use of your account and password, you must immediately notify us. You may send an email to service@rheofit.com to submit your request. You understand and agree that it takes a reasonable time for Yunwang Innovation to take action based on your request, and Yunwang Innovation assumes no liability for any adverse consequences that have already arisen before such action is taken. Account theft or loss caused by malicious attacks by others, your own reasons, or other force majeure factors shall be borne by you personally, and Yunwang Innovation assumes no liability.

Your account is for your personal use only and may not be lent or shared with others. When your account is subject to unauthorized use, you shall immediately notify our platform; otherwise, unauthorized use shall be deemed your own acts, and you shall solely bear all losses and consequences arising therefrom.

We maintain an account security risk-control system that monitors abnormal logins, bulk registrations, abnormal operations, and similar conduct, and may record certain risk URLs and device anomaly information to prevent phishing, fraud, and Trojan viruses. If we detect that an account has been compromised, is being used for fraud, or poses other security risks, we are entitled to temporarily freeze account functions and notify you to complete identity verification.

In principle, we will not transfer control of your personal information to other companies, organizations, or individuals. If a merger, acquisition, or bankruptcy liquidation occurs involving a transfer of personal information, we will process your personal information in accordance with the Privacy Policy.

2.4 Network Security

The Software may contain links to other independent third-party Yunwang Innovation sites. Such links are provided solely for the convenience of visitors to Yunwang Innovation. Yunwang Innovation makes no express or implied warranty regarding the content, services, information, or the like of such links, and such links shall not be deemed a recommendation, endorsement, or authorization by Yunwang Innovation. You should carefully judge your interactions with such links.

The security and confidentiality of the network connection and data transmission between you and Yunwang Innovation are affected by the technologies adopted by you and your telecommunications carrier, or by other external factors beyond Yunwang Innovation. Although Yunwang Innovation has adopted prudent internal security management systems and operating procedures and technical measures to prevent computer viruses and cybersecurity hazards such as network attacks and intrusions, information and data you send to Yunwang Innovation may still be intercepted by others, and Yunwang Innovation cannot guarantee the security and confidentiality of the network connection and data transmission between you and Yunwang Innovation.

4.7 Artificial Intelligence Feature Statement

When you use generative artificial intelligence features/services provided by our platform, you acknowledge and agree that all content generated by the current features/services is generated by artificial intelligence models; we make no warranty as to the accuracy, completeness, or functionality of such generated content, and such generated content does not represent our attitude or views. The services we provide are based on information accumulated from sources permitted by laws and regulations, including but not limited to the public Internet, and have undergone continuous automatic and manual filtering of sensitive data; however, it cannot be excluded that some information may contain defects, be unreasonable, or cause discomfort.

4.8 Yunwang AI Smart Feature Health Notice

Yunwang AI generates reference massage plans for post-exercise recovery and daily muscle relaxation, based on exercise information entered by the user, pain locations, bodily feedback, historical usage records, and actively uploaded image, text, and voice materials, to generate suggestions on massage intensity, duration, body areas, and procedures. This feature is not a medical device service, has no effect as medical diagnosis, injury treatment, or rehabilitation prescription, and cannot replace professional medical opinions of licensed physicians or rehabilitation therapists.

After a plan is generated, the user must preview it manually, may adjust massage intensity, target areas, and runtime, and must manually start the device after confirmation; during operation, the device may be stopped at any time via the App, remote control, or on-device buttons. Direct application to bony prominences, the anterior neck, open wounds, or acute injury sites is prohibited; first-time use shall uniformly start from low-intensity settings.

If you have an acute sports injury, persistent severe pain, limb numbness, coagulation disorders, circulatory diseases, severe osteoporosis, pregnancy, or implanted medical devices, you must consult professional medical personnel before use; if discomfort occurs during use, stop the device immediately and seek medical help.

Voice, photo, video, and text materials uploaded by the user must be from lawful sources, and the user must hold full authorization for use; third-party likenesses, identity documents, medical records, or illegal materials must not be uploaded; Yunwang AI will not perform facial recognition, voiceprint collection, or biometric profiling; materials uploaded by users are stored privately by default and will not be automatically opened for other users to view.

4.9 Boundary Between Offline and Connected Features

Without registration, login, or network connection, users may use standard massage modes such as basic rolling, spot press, zone auto-run, start/stop, and direction change via on-device physical buttons, local Bluetooth, and the remote control. Offline use generates no cloud records throughout, and the device will not automatically backfill local operation data upon subsequent connection; Bluetooth scanning on older Android systems requires location permission due to underlying system limitations; we do not collect, store, or parse the user’s actual location.

App beginner tutorials, cloud storage of usage records, multi-device data sync, and Yunwang AI personalized massage plans are connected-only features and cannot be used without a network or account login; network interruption, cloud service maintenance, or account anomalies affect only value-added features and shall not disable the device’s local offline basic massage operations. Termination of account connected services shall not artificially lock the local offline basic massage functions of hardware already purchased by the user.

You may enable “Local Mode” in App settings; in this mode, all usage data is stored only locally on your phone and device and will not be uploaded to any server. After Local Mode is enabled, cloud sync, Yunwang AI, and other cloud features will be unavailable.

Users must complete charging and maintenance in accordance with the product manual; private disassembly or modification of hardware, bypassing of device safety limits, and use of non-official accessories are strictly prohibited; personal injury or hardware damage caused by non-compliant use shall be borne by the user. The effects of using the Smart Device vary by individual; when using exercise suggestions or controlling the device for massage, please act according to your own physical condition. If you feel unwell, stop use immediately and consult a doctor.

Original voice, images, and videos uploaded by the user will be automatically deleted within 24 hours after Yunwang AI plan generation is completed; only materials for which the user manually selects “Save to history” will be retained in the cloud, and users may delete individual items manually.

4.11 Product Warranty and Safety Recall

Hardware warranty terms for the Smart Device are subject to the Warranty Card in the product packaging and the after-sales policy published on the official website. Nothing in this Agreement excludes or limits your statutory warranty rights as a consumer.

If a product is found to have a safety hazard or requires a recall, we will notify you via App push, email, SMS, official website announcement, or other means, and provide free repair, replacement, or return services as required by laws and regulations.
