Refund Policy

Effective Date: June 7, 2026

This Refund Policy explains how refunds, cancellations, free trials, renewals, and billing issues work for AcornKB.

AcornKB is operated by Chenjun Xu, an individual developer doing business as AcornKB ("AcornKB", "we", "us", or "our").

Payments for AcornKB may be processed by Paddle, which may act as the merchant of record, reseller, payment processor, tax calculation provider, invoicing provider, subscription management provider, and refund handling provider.

This Refund Policy does not limit any mandatory refund, withdrawal, cancellation, or consumer rights that you may have under applicable law.

1. Free Trial

AcornKB may offer a 30-day free trial.

Trial terms, trial duration, plan features, renewal price, subscription period, and any applicable taxes or fees will be shown at checkout, on the pricing page, or in the applicable product page.

Unless canceled before the trial ends, a free trial may convert into a paid annual subscription at the price shown at checkout or on the applicable product page.

You are responsible for canceling before the end of the trial period if you do not want to be charged.

2. Subscription Renewal

AcornKB subscriptions may renew automatically unless canceled before the next renewal date.

If your subscription renews automatically, you authorize recurring charges until you cancel.

Renewal terms, billing period, and renewal price will be shown at checkout, in the billing portal, or in the applicable product page.

3. Cancellation

You may cancel your subscription at any time before the next renewal.

Cancellation stops future renewals. Cancellation does not automatically refund amounts already paid unless you are eligible for a refund under this Refund Policy, Paddle's applicable buyer terms, or applicable law.

You can cancel through:

  • the Paddle customer portal link provided in your receipt email;
  • the billing page or account page, if available;
  • Paddle support channels, where applicable;
  • contacting us at support@acornkb.com.

If you contact us to cancel, please use the email address associated with your purchase and include your order ID if available.

4. Refund Window

For initial purchases and renewals, refund requests may be accepted within 14 days of the transaction date, unless a longer refund, cancellation, or withdrawal period is required by applicable law.

Refunds are not automatic. Each request may be reviewed based on the purchase, usage, timing, payment status, account status, applicable law, Paddle's policies, and evidence of abuse or fraud.

5. When Refunds May Be Granted

Refunds may be granted when:

  • you were charged after a free trial and request a refund within the refund window;
  • you accidentally purchased the wrong plan;
  • you experienced a technical issue that prevents reasonable use of the product and we are unable to resolve it;
  • you were charged after a cancellation request that was submitted before renewal but not processed correctly;
  • applicable law requires a refund;
  • we determine, in our discretion, that a refund is appropriate.

6. When Refunds May Be Declined

Refunds may be declined when:

  • the request is made after the applicable refund window;
  • there is evidence of fraud, abuse, or misuse;
  • there are repeated refund requests;
  • there is chargeback abuse or payment dispute abuse;
  • the license, subscription, or trial was abused, shared, leaked, resold, or used beyond permitted limits;
  • the Service was used in violation of our Terms and Conditions;
  • the request is based on third-party provider costs, AI provider charges, transcription provider charges, API usage charges, or platform costs outside AcornKB;
  • the issue is caused by unsupported local environments, third-party services, platform restrictions, user misconfiguration, or provider outages outside our control;
  • the purchase was already refunded;
  • applicable law does not require a refund and we determine that the request is not reasonable.

7. Third-Party Provider Costs

AcornKB may allow you to configure third-party AI providers, transcription providers, model APIs, embedding providers, or other external services.

We are not responsible for fees, credits, usage charges, API costs, subscription fees, or other charges imposed by third-party providers you configure or use.

Refunds for AcornKB do not include refunds for third-party provider costs unless expressly stated by that provider.

8. Paddle Refund Processing

Where your purchase is processed by Paddle, refund requests may also be subject to Paddle's buyer terms, refund rules, statutory rights handling, fraud prevention rules, and support procedures.

Paddle may process refunds to the original payment method where applicable.

Refund timing may depend on Paddle, your payment method, your bank, card network rules, and applicable law.

9. Chargebacks and Payment Disputes

If you have a billing issue, please contact us at support@acornkb.com or use Paddle's support channels before initiating a chargeback or payment dispute.

We may suspend or revoke access to the Service, licenses, subscriptions, support, or entitlements if a payment is reversed, charged back, disputed, suspected to be fraudulent, or not successfully completed.

This does not limit any rights you may have under applicable law.

10. How to Request a Refund

To request a refund, contact us at support@acornkb.com or use the Paddle support link provided in your receipt email.

Please include:

  • the email address used for purchase;
  • order ID or invoice ID, if available;
  • purchase date, if available;
  • reason for the refund request;
  • any relevant screenshots or error details if the request relates to a technical issue.

We may ask for additional information to verify the purchase or evaluate the request.

11. Changes to This Refund Policy

We may update this Refund Policy from time to time.

If changes are material, we will provide reasonable notice through the website, app, email, checkout page, or another appropriate channel.

The updated Refund Policy will be effective as of the effective date stated in the updated version, unless otherwise required by law.
