14. Changes to Terms

We may update these Terms from time to time. We will provide at least thirty (30) days' advance notice of significant changes via email or a prominent notice on our website. Continued use of our services after changes constitutes acceptance of the updated Terms.

15. Governing Law

These Terms are governed by and construed in accordance with the laws of the State of Delaware, United States, without regard to its conflict of law provisions.

16. Dispute Resolution

Informal Resolution

Before filing any formal proceeding, you agree to try to resolve any dispute informally by contacting us at [email protected]. We will try to resolve the dispute within 30 days.

Binding Arbitration

If we cannot resolve a dispute informally, any dispute, claim, or controversy arising out of or relating to these Terms or the Services (including their formation, performance, or breach) shall be settled by binding arbitration administered by the American Arbitration Association (AAA) under its Commercial Arbitration Rules. The arbitration will be conducted in English in the State of Delaware, and the arbitrator's decision will be final and binding.

Class Action Waiver

You and LunaRabbit agree that any dispute resolution proceedings will be conducted only on an individual basis and not in a class, consolidated, or representative action. If this class action waiver is found to be unenforceable, then the entirety of this arbitration provision shall be null and void.

Small Claims Exception

Notwithstanding the above, either party may bring an individual action in small claims court for disputes within the court's jurisdiction.

Consumer Protection Carve-Out

If you are a consumer resident in South Korea, the binding arbitration and class action waiver provisions above do not apply to you. Instead, any dispute shall be resolved in the courts of your country of residence, in accordance with the mandatory consumer protection laws of that jurisdiction, including your rights before Korea's Consumer Dispute Settlement Commission (소비자분쟁조정위원회).

Opt-Out

You may opt out of this arbitration provision by sending written notice to [email protected] within 30 days of first accepting these Terms. If you opt out, disputes will be resolved through the state or federal courts located in the State of Delaware.

17. Severability

If any provision of these Terms is found to be invalid, illegal, or unenforceable by a court of competent jurisdiction, such invalidity shall not affect the validity of the remaining provisions, which shall remain in full force and effect.

18. Entire Agreement

These Terms, together with our Privacy Policy, Cookie Policy, Acceptable Use Policy, and Refund Policy, constitute the entire agreement between you and LunaRabbit regarding the use of our Services, and supersede all prior agreements, understandings, and communications, whether written or oral.

19. Assignment

You may not assign or transfer these Terms or your rights under these Terms, in whole or in part, without our prior written consent. We may assign these Terms at any time without notice, including in connection with a merger, acquisition, or sale of assets. Any purported assignment in violation of this section shall be void.

20. Waiver

No waiver of any provision of these Terms shall be deemed a further or continuing waiver of such provision or any other provision. Our failure to assert any right or provision under these Terms shall not constitute a waiver of such right or provision.
