IN NO EVENT SHALL SHIELDTUNE, LLC'S TOTAL CUMULATIVE LIABILITY TO YOU FOR ALL CLAIMS ARISING FROM OR RELATED TO THE SERVICE EXCEED THE GREATER OF (A) FIFTY DOLLARS ($50.00) OR (B) THE TOTAL AMOUNT YOU PAID TO SHIELDTUNE, LLC IN THE SIX (6) MONTHS IMMEDIATELY PRECEDING THE EVENT GIVING RISE TO THE CLAIM.
YOU EXPRESSLY ASSUME ALL RISK ASSOCIATED WITH USING AI-GENERATED TECHNICAL GUIDANCE. THE LIABILITY CAP AND DISCLAIMER ABOVE REFLECT A REASONABLE ALLOCATION OF RISK BETWEEN THE PARTIES AND ARE A FUNDAMENTAL ELEMENT OF THE BASIS OF THE BARGAIN BETWEEN THE PARTIES.

PLEASE READ THIS SECTION CAREFULLY. IT AFFECTS YOUR LEGAL RIGHTS, INCLUDING YOUR RIGHT TO FILE A LAWSUIT IN COURT.
Binding Arbitration: Except for claims that qualify for small claims court, you and ShieldTune, LLC agree that any dispute, claim, or controversy arising out of or relating to these Terms or the Service shall be resolved exclusively by binding individual arbitration administered by the American Arbitration Association (AAA) under its Commercial Arbitration Rules. The arbitration shall take place in Wake County, North Carolina, or remotely by mutual agreement. The arbitrator's award shall be final and binding and may be entered as a judgment in any court of competent jurisdiction.
Class Action Waiver: YOU AND SHIELDTUNE, LLC EACH WAIVE ANY RIGHT TO PARTICIPATE IN A CLASS ACTION LAWSUIT OR CLASS-WIDE ARBITRATION. ALL CLAIMS MUST BE BROUGHT IN YOUR INDIVIDUAL CAPACITY AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY PURPORTED CLASS OR REPRESENTATIVE PROCEEDING.
Opt-Out: You may opt out of the arbitration agreement by sending written notice to support@shieldtune.com within 30 days of first accepting these Terms. Opting out does not affect any other provision of these Terms.
We shall not be liable for any failure or delay in performance due to circumstances beyond our reasonable control, including but not limited to acts of God, natural disasters, internet outages, or the downtime or failure of third-party AI API providers.

For any claims not subject to arbitration under Section 10, the parties consent to the exclusive jurisdiction of the state and federal courts located in Wake County, North Carolina.
If any provision of these Terms is held to be unenforceable, that provision will be modified to the minimum extent necessary to make it enforceable, and the remaining provisions will remain in full force and effect.
