1. All payments are final. Fibonacci subscriptions, monthly (USD 50) or annual (USD 540), are non-refundable. No full, partial or prorated refunds are given for:

• early cancellation;
• unused periods or non-use;
• change of mind;
• service interruptions described in section 9 of the Terms.

2. Try before you pay. We offer a 7-day free trial so you can evaluate Fibonacci before any charge. If you cancel during the trial, you are not charged anything.

3. Cancellation. You can cancel at any time from Settings → Plan and billing. You will keep access until your next renewal date and there will be no further charges. You will receive a confirmation email.

4. Billing errors. If you notice a duplicate charge, a charge after a valid cancellation or an amount different from your plan, write to us at [email protected] within 30 days of the charge, with your account email and the payment reference. We will correct it to the same payment method. This is not a refund, but the correction of an incorrect charge.

5. Chargebacks. Before starting a chargeback with your bank, contact us to resolve any billing error. Unfounded chargebacks may lead to account suspension.

6. Mandatory laws. This policy applies to the maximum extent permitted by applicable law.
