If you are charged for a renewal you did not want, or are dissatisfied with the service, you have no contractual right to get your money back.
Calm's Terms significantly affect consumers' legal rights by requiring individual arbitration for most disputes and waiving the right to participate in class actions, which limits consumers' ability to seek collective redress. Subscriptions auto-renew without a right to refund, and Calm can change prices with notice but no guaranteed right to a refund if you disagree. You can opt out of the mandatory arbitration clause by sending a written opt-out notice to Calm within 30 days of first agreeing to these Terms.
