TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, THE COMPANY EXPRESSLY DISCLAIMS ALL WARRANTIES, INCLUDING BUT NOT LIMITED TO:
No advice or information obtained by You from the Company or through the Platform, whether oral or written, shall create any warranty not expressly stated in these Terms.
Some jurisdictions do not allow the exclusion of certain implied warranties, so some of the above exclusions may not apply to You. In such cases, the Company's warranties are limited to the greatest extent permitted by applicable law.
Products sold through the Platform are subject only to the manufacturer's warranty, if any, unless otherwise expressly stated by the Company.

This indemnification obligation shall survive the termination of these Terms and Your use of the Platform.

Your interactions with third-party providers, including payment processors, shipping carriers, analytics services, advertisers, and social media platforms, are solely between You and those third parties. You should review the applicable terms and policies of any third-party website or service before using it or providing any personal information.
The Company may integrate with third-party payment gateways, authentication services, and analytics tools.

Any dispute, controversy, or claim arising out of or relating to these Terms or the use of the Platform shall first be resolved through good-faith negotiations between the parties. If the dispute cannot be resolved through negotiation within thirty (30) days, either party may submit the dispute to binding arbitration administered by a recognized arbitration institution in Yuncheng, Shanxi Province, in accordance with its applicable rules.
The language of the arbitration shall be Chinese, and the arbitral award shall be final and binding upon both parties. Judgment on the award may be entered in any court having jurisdiction thereof.
Class Action Waiver: TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, YOU AND THE COMPANY AGREE THAT ANY DISPUTE RESOLUTION PROCEEDINGS SHALL BE CONDUCTED ON AN INDIVIDUAL BASIS AND NOT AS A CLASS, CONSOLIDATED, OR REPRESENTATIVE ACTION. YOU WAIVE ANY RIGHT TO PARTICIPATE IN A CLASS ACTION OR MULTI-PLAINTIFF LAWSUIT AGAINST THE COMPANY.
Notwithstanding the foregoing, the Company may seek injunctive or other equitable relief in any court of competent jurisdiction to protect its Intellectual Property Rights, confidential information, or to enforce compliance with these Terms.
If any provision or part of a provision of these Terms is held to be invalid, illegal, or unenforceable by a court of competent jurisdiction, such provision shall be enforced to the maximum extent possible and the remaining provisions of these Terms shall remain in full force and effect. The invalid, illegal, or unenforceable provision shall be deemed modified to the minimum extent necessary to make it valid, legal, and enforceable while preserving its original intent.
If such modification is not possible, the invalid provision shall be severed from these Terms, and the remainder of these Terms shall continue to be binding and enforceable as if such severed provision had never been included. The parties agree to replace any severed provision with a valid provision that most closely approximates the original legal and economic intent of the severed provision.
The failure of the Company to exercise or enforce any right or provision of these Terms shall not constitute a waiver of such right or provision, nor shall it prevent the Company from exercising such right or provision at a later time.
These Terms, together with any documents, policies, or agreements expressly incorporated herein by reference (including but not limited to the Privacy Policy, Return and Refund Policy, and any applicable seller terms), constitute the entire and exclusive agreement between You and Yuncheng Longjin Technology Co., Ltd. regarding Your use of the Platform and supersede all prior or contemporaneous understandings, agreements, representations, and warranties, whether written or oral, relating to such subject matter.
No modification, amendment, or waiver of any provision of these Terms shall be effective unless made in writing and signed by an authorized representative of the Company. The Company's failure to insist upon or enforce strict performance of any provision of these Terms shall not be construed as a waiver of any provision or right.
You acknowledge that in entering into these Terms, You have not relied on, and shall have no right or remedy in respect of, any statement, representation, assurance, or warranty (whether made negligently or innocently) other than as expressly set out in these Terms.
The Company reserves the right, at its sole discretion, to modify, amend, or revise these Terms at any time and for any reason.
