Terms of Service

1. Acceptance of these terms

These Terms of Service ("Terms") govern your use of the LU&BA mobile application and the account service behind it (together, the "Service"). By installing, registering for or using the Service, you agree to these Terms and to our Privacy Policy. If you do not agree, do not use the Service.

2. Who we are

The Service is provided by DJM Trading Limited, a body corporate incorporated in Hong Kong, with its registered office at RM 701, Unit 108, 7/F, Tower B, New Mandarin Plaza, 14 Science Museum Road, Tsim Sha Tsui, Kowloon, Hong Kong (Company No. 78301925; Business Registration No. 78301925-000-06-26-9).

3. Eligibility

You must be at least 16 years old to create an account. If you are under 18, you may use the Service only with the involvement of a parent or legal guardian. By using the Service you confirm that the information you provide is accurate and that you have the legal capacity to enter into these Terms.

4. Your account

• Your account is identified by an email address, confirmed with a one-time verification code.
• You are responsible for keeping access to that email address secure, and for activity that takes place under your account.
• One account may bind the number of devices stated in the product documentation for the device.
• Notify us immediately at dejichuangxin@djmiot.com.cn if you become aware of unauthorised use of your account.
• You may request deletion of your account at any time. The Privacy Policy explains what happens to your data when the account is closed.

5. Intended use

The information the Service displays — intensity level, operating mode, session duration, consumable status, firmware version and device messages — describes how the device is set and how it has been used. It is a device reading, not a measurement of your body or your skin, and it must not be used to make a decision about your health.

The Service is designed to operate LU&BA branded devices only. It is not a general purpose Bluetooth controller and will not connect to devices from other manufacturers.

6. Device safety

• Use the device only as described in its user manual, and only with the accessories and consumables specified by the manufacturer.
• Do not use the device on broken, irritated or inflamed skin, or on any area the manufacturer's instructions exclude.
• Stop using the device and seek professional advice if you experience pain, unusual redness, swelling or any adverse reaction, and do not resume use until you have done so.
• If you have a skin condition, are pregnant, or use an implanted electronic device, consult a qualified healthcare professional before use.
• Keep the device, its accessories and its small parts away from children.
• Do not open, modify or repair the device yourself. Doing so voids the warranty and may create a safety hazard.
• Do not use the app while driving or while operating machinery.

7. Acceptable use

You agree not to:

• use the Service for any unlawful purpose, or in breach of any applicable regulation;
• reverse engineer, decompile or attempt to extract the source code of the app, except where such a restriction is prohibited by law;
• interfere with, disrupt or overload the Service or the servers it relies on;
• attempt to gain unauthorised access to any account, system or network;
• use the Service to build a competing product, or to copy its behaviour or data model;
• resell, sublicense or commercially exploit access to the Service without our written consent;
• register an account on behalf of someone else without their permission, or create accounts by automated means.

8. Intellectual property

The Service, including its software, design, text, graphics, logos and trademarks, is owned by us or our licensors and is protected by intellectual property law. We grant you a personal, non-exclusive, non-transferable, revocable licence to use the app on devices you own or control, for the purpose described in these Terms. No other rights are granted.

"LU&BA" and "鹿巴荟", together with the associated logos, are our marks. You may not use them without our prior written permission.

9. Third-party services

The app is distributed through Google Play. Your use of Google Play is governed by Google's own terms, and Google is not a party to these Terms and has no obligation to provide support for the Service.

The app contains no advertising and no analytics software. Our application servers are operated on our instructions by Shenzhen DJM Innovation Industrial Co., Ltd.; section 8 of the Privacy Policy describes the parties involved and the data they receive.

10. Availability and changes

• We may update, modify or discontinue features of the Service. Where a change materially affects your use, we will give reasonable notice in the app.
• The Service requires a compatible LU&BA device, a supported Android version, and network access for sign-in and records. Bluetooth functions require the device to be within range.
• We do not guarantee uninterrupted availability. Maintenance, network conditions and events outside our control may interrupt the Service.

11. Disclaimer of warranties

To the maximum extent permitted by law, the Service is provided "as is" and "as available", without warranties of any kind, whether express or implied, including implied warranties of merchantability, fitness for a particular purpose and non-infringement. We do not warrant that the Service will be error-free or uninterrupted, or that every defect will be corrected.

Nothing in these Terms excludes or limits any warranty or right that cannot be excluded or limited under the mandatory law of your country of residence. If you are a consumer in the European Union, the United Kingdom or another jurisdiction with mandatory consumer protection rules, those rules apply notwithstanding this section. Warranties for the physical device are set out in the documents supplied with the device.

12. Limitation of liability

To the maximum extent permitted by law, we are not liable for indirect, incidental, special, consequential or punitive damages, or for loss of profit, revenue, data or goodwill, arising from or relating to your use of the Service.

Our total aggregate liability arising out of or relating to the Service is limited to the amount you paid us for the Service in the twelve months preceding the event giving rise to the claim, or one hundred Hong Kong dollars (HKD 100) if you paid nothing.

Nothing in these Terms limits liability for death or personal injury caused by negligence, for fraud, or for any other liability that cannot be limited by law.

13. Termination

You may stop using the Service at any time and request deletion of your account. We may suspend or terminate your access if you materially breach these Terms, if required by law, or if continuing to provide the Service becomes impractical. On termination the licence granted in section 8 ends. Sections that by their nature should survive termination — including sections 8, 11, 12 and 14 — continue to apply.

14. Governing law

These Terms are governed by the laws of the Hong Kong Special Administrative Region of the People's Republic of China. The courts of Hong Kong have exclusive jurisdiction over disputes arising from these Terms, without prejudice to any mandatory right you have as a consumer to bring proceedings in your country of residence.
