MathStackAI Refund Policy

1. Subscription Refunds

All subscription purchases (monthly or annual) are non-refundable unless required by law. When you subscribe to our "Pro" plan, you gain immediate access to premium features, and we do not offer prorated refunds for unused time.

You may cancel your subscription at any time, and you will retain access to premium features through the end of your billing period. No further charges will be made after cancellation.

2. Stack Pack Purchases (One-Time)

All Stack Pack purchases are final and non-refundable. Stacks are a digital currency used to access premium features or problem sets, and once delivered, they cannot be refunded, returned, or exchanged.

3. Exceptions

We may issue refunds under the following circumstances:

• You were charged in error (e.g., duplicate transactions).
• You experienced a technical issue that prevented access to purchased features or content and contacted our support team within 7 days of the issue.
• You are located in a region where consumer protection laws require a refund (e.g., within a mandatory cooling-off period in the EU or UK).

To request a refund under one of these exceptions, contact us at support@mathstackai.com with your account email and transaction details.

4. How Refunds Are Processed

If approved, refunds will be issued to your original payment method through our payment processor, Paddle. Please allow 5–10 business days for the refund to appear, depending on your financial institution.

5. Policy Updates

We reserve the right to modify this Refund Policy at any time. Any changes will be reflected with an updated effective date on this page.
