Disclaims all warranties (accuracy, availability, non-infringement, merchantability, fitness for purpose) on an as-is and as-available basis and limits the operator's liability for indirect, incidental, special, consequential, exemplary, or punitive damages and loss of data, goodwill, profits, or health outcomes, to the fullest extent permitted by law.
