10. Disclaimers and Limitation of Liability

Service Accuracy

Disclaimer of Warranties

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING BUT NOT LIMITED TO WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT.

Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, WONTBOUNCE INC. SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, INCLUDING WITHOUT LIMITATION LOSS OF PROFITS, DATA, BUSINESS OPPORTUNITIES, GOODWILL, OR OTHER INTANGIBLE LOSSES, ARISING OUT OF OR IN CONNECTION WITH YOUR USE OF THE SERVICE.

Maximum Liability

Our total aggregate liability for any claims arising under these Terms or related to the Service shall not exceed the total amount you have paid to Wontbounce in the twelve (12) months immediately preceding the event giving rise to the claim.

11. Indemnification

You agree to indemnify, defend, and hold harmless Wontbounce Inc., its officers, directors, employees, contractors, and agents from and against any claims, damages, obligations, losses, liabilities, costs, or expenses (including reasonable attorney's fees) arising from: (a) your use of the Service; (b) your violation of these Terms; (c) your violation of any third-party rights, including privacy or intellectual property rights; or (d) the email addresses or data you submit to the Service.

13. Governing Law and Dispute Resolution

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

Any dispute arising from or relating to these Terms or the Service shall first be attempted to be resolved through good-faith negotiation. If the dispute cannot be resolved through negotiation within 30 days, it shall be submitted to binding arbitration in accordance with the rules of the American Arbitration Association. Nothing in this section prevents either party from seeking injunctive or equitable relief in a court of competent jurisdiction.

14. Severability

If any provision of these Terms is found to be unenforceable or invalid by a court of competent jurisdiction, that provision shall be limited or eliminated to the minimum extent necessary, and the remaining provisions shall remain in full force and effect.
