Important Notice & Dispute Resolution Warning
Important Notice:
The dispute resolution terms applicable to you may vary depending on your country or region of residence, the applicable contracting entity, and governing laws. To the maximum extent permitted by applicable law (including for all users located in the United States), this Agreement requires that all disputes be resolved through binding individual arbitration rather than through court litigation. This means that both you and we waive the right to a jury trial and the right to participate in class actions. Please carefully review Section 16, “Dispute Resolution and Arbitration,” for detailed information.
By accessing, browsing, or using our services, creating an account, or making any purchase through our platform, you acknowledge that you have read, understood, and agreed to be bound by this Agreement. If you do not agree with any part of this Agreement, please immediately discontinue your access to and use of our services.
