The Company does not guarantee their accuracy, completeness, or fitness for any particular purpose. You are solely responsible for reviewing, validating, and applying any AI-generated content. AI outputs should be treated as reference material only, not as professional advice.

You agree to provide accurate and complete payment information. By subscribing, you authorize us to charge your selected payment method for all applicable fees. We reserve the right to correct any errors in pricing, even after payment has been received, and to refuse any order placed through the Service.
We will provide advance notice via our website or email before implementing any fee changes.
8. Cancellation and Refund
You may cancel your subscription at any time by contacting our support team. Cancellation takes effect upon receipt of your notice by the Company.
