You may opt out of allowing your Content to be used for model improvement and research purposes by contacting us at [email protected]. We will honor your choice in accordance with applicable law.
Due to the inherent uncertainty and limitations of AI and machine learning technologies, we make no guarantees regarding the accuracy, completeness, or usefulness of any Output. You acknowledge and agree to the following:
Do not treat Output as factual or authoritative. You are responsible for independently evaluating its accuracy, reliability, and appropriateness for your use.
Output is not professional advice. It is not a substitute for consultation with qualified professionals in fields such as medicine, law, finance, education, or any other regulated area.
Do not rely on Output for high-stakes decisions. You may not use Output relating to any identifiable person to make decisions that could have legal or material impact on them, including decisions regarding credit, employment, housing, insurance, education, or healthcare.

Your Payment Method will be charged for each renewal term unless you cancel the Subscription in accordance with these Terms. If the Subscription has an initial commitment period (the "Initial Term"), this will be disclosed at checkout. After the Initial Term, your Subscription will be renewed for successive periods of the same length (each a "Renewal Term") until canceled.
Free Trials. If you are offered a free trial, we or our third-party service provider will automatically bill your payment method on the later of (i) the day your free trial ends or (ii) the day you start your paid subscription, and on each recurring billing date thereafter. You will not receive notice that your free trial has ended and that payment for your subscription is due. To avoid charges, you must cancel your subscription prior to midnight Pacific Standard Time on the last day of your free trial period. If you cancel during a free trial, cancellation may be effective immediately.

To avoid being charged for the next billing period, you must cancel at least 24 hours before the current term ends.
