RINGRINX Terms of Use

Effective date: September 3, 2026 Version: 2026.09.03

Welcome to RINGRINX. RINGRINX is a smart-ring companion app provided by Shenzhen Chujiao Technology Co., Ltd. (registered address: Room 102, Building A, Lidao Mingyuan, No. 4220 Xili Lake Road, Xili Subdistrict, Nanshan District, Shenzhen, China; “we”, “us”, or “our”). These Terms govern your use of the App, software updates, and related local features. Do not install or use the App if you do not agree.

1. Service and licence

We grant you a personal, revocable, non-exclusive, non-transferable licence to use the App for non-commercial purposes: connecting a compatible RINGRINX smart ring, viewing locally stored wellness and activity-reference records, configuring the device, and managing local data. Available features depend on ring model, firmware, phone system, region, and permissions you choose to grant.

The initial release has no account, cloud sync, advertising, subscription, or in-app purchase. We may issue updates for security, compatibility, or improvements. You may choose whether to install an update where your device permits, but older versions may no longer be supported.

2. Important health and safety notice

RINGRINX and the smart ring are for general wellness, sleep, and activity reference. They are not medical devices and do not provide diagnosis, treatment, disease prevention, medical monitoring, or emergency services. Heart rate, HRV, blood oxygen, temperature, sleep, activity, alert, and other information shown by the App may be inaccurate, incomplete, or delayed and must not replace professional medical advice.

For chest pain, breathing difficulty, fainting, abnormal heart rate, or another urgent symptom, contact a clinician or local emergency service immediately. Do not rely on the App, ring, or an alert. Wear, charge, and use the ring safely according to its instructions. Stop use and seek professional help if it causes discomfort, skin irritation, or is difficult to remove.

3. Your responsibilities

You must ensure that profile, exported, or other information you use is accurate, lawful, and yours to use; protect your phone, ring, and exported files; use approved App versions, devices, accessories, and firmware; and not use the App in a manner that is unsafe, unlawful, infringes others’ rights, or interferes with the App.

Except where law permits, you may not copy, rent, sell, sublicense, reverse engineer, decompile, circumvent technical protections, use the App commercially, distribute it in bulk, or use it to develop a competing product without our written permission.

4. Permissions, data, and deletion

The App asks for Bluetooth, notifications, notification-listener access, phone state, or system-picker access only when you choose the related feature. You may revoke access in system settings; related connection, alert, export, or selection features may then be unavailable.

Health and activity records, profile, settings, and ring references are encrypted and stored locally on your phone by default. In Settings > Data management, you can export selected records as a CSV, delete health history, or unpair the ring and delete all local data. Deleting App data does not factory-reset the ring or erase files you saved or shared elsewhere. Records still on the ring may sync again after re-pairing. See the RINGRINX Privacy Policy for details.

5. Third-party systems and connectivity

The App may invoke Android or iOS system functions, such as Bluetooth, notifications, file pickers, phone, and messaging. If you choose to share, export, dial, text, or provide information through a system interface, you are responsible for the destination and its terms and privacy practices. We are not responsible for third-party services’ availability, content, or data practices.

Wireless connection, operating-system restrictions, ring battery, wearing signal, and firmware can interrupt functions or cause sync failures and delayed data. Do not use the App where continuous, error-free, or safety-critical operation is required.

6. Intellectual property

The App, its interface, text, images, trademarks, software, and related content are protected by applicable intellectual-property laws. Except for the licence expressly granted here, all rights are reserved by us or the relevant owner. Use of the RINGRINX name or logo requires our written permission.

7. Changes, suspension, and liability

To the extent allowed by law, we may change, suspend, or discontinue functions for maintenance, security, compliance, technical updates, or discontinuation, with notice where reasonably practicable. We are not liable, to the extent permitted by law, for loss caused by force majeure, third-party services, device failures, unauthorised modification, your actions, or matters outside our reasonable control.

Nothing in these Terms excludes or limits liability that cannot lawfully be excluded or limited, or your mandatory consumer rights.

8. Updates, law, and contact

We may update these Terms. We will provide notice of material changes through the App, website, or another appropriate method. Continuing to use the App after an update means that you accept the updated Terms to the extent allowed by law; otherwise, stop using the App and delete your local data.

These Terms are governed by the laws of mainland China. Mandatory consumer-protection laws in your place of residence continue to apply where required. Please try to resolve disputes with us first; unresolved disputes may be brought before a court with jurisdiction.
