Refund Policy#

Leftoak Labs, LLC

Effective Date: August 14, 2026

1. Overview#

This Refund Policy explains how Leftoak Labs, LLC ("Leftoak Labs," "we," "us," or "our") handles refund requests for payments made through our websites and applications (collectively, the "Services"), including Voluntary Payments, paid subscriptions, and any other fees (each as defined in our Terms of Service). This Refund Policy is part of and subject to our Terms of Service.

Certain Services may have additional refund terms specific to their payment model, which are described in Application-Specific Addenda at the end of this policy.

Current addenda:

• Addendum A: fretengine (guitar instruction and practice tools)

2. General Refund Principles#

Leftoak Labs strives to be transparent about payments and refund eligibility before any transaction occurs. The following general principles apply across all Services:

• Clearly communicated terms. We disclose payment terms, including refund eligibility, before you complete any transaction.
• Payment processing. All payments are processed by Stripe, our third-party payment processor. Stripe supports a variety of payment methods as described on their platform. You provide your payment information directly to Stripe. We do not collect or store payment card details on our servers.
• Processing errors. If a payment was processed in error (such as a duplicate charge or incorrect amount), we will work with you and our payment processor to correct the error and issue a refund for the erroneous amount.
• Unauthorized transactions. If you believe a transaction was unauthorized, contact us immediately at support@leftoak.com. We will investigate and, if the charge is confirmed as unauthorized, issue a refund or direct you to Stripe's dispute process.

3. Refunds for Paid Subscriptions#

3.1 Cancellation#

YOUR SUBSCRIPTION WILL CONTINUE AUTOMATICALLY UNTIL YOU CANCEL. You may cancel a Paid Subscription at any time. Upon cancellation:

• Your subscription remains active until the end of your current billing period.
• You will not be charged for subsequent billing periods.
• No prorated refunds are issued for the unused portion of the current billing period.

Cancellation terms are also described in the applicable addendum and in our Terms of Service.

3.2 Tier Downgrades#

If you downgrade from a higher subscription tier to a lower tier (e.g., from the Navigator Plan to the Solo Plan), the downgrade takes effect at the end of your current billing period. No prorated refund is issued for the difference in tier pricing for the current billing period.

3.3 Satisfaction-Based Refunds#

If you are unsatisfied with a Paid Subscription, we encourage you to contact us at support@leftoak.com. We evaluate satisfaction-based refund requests on a case-by-case basis and may, at our sole discretion, issue a full or partial refund. Satisfaction-based refunds are a goodwill courtesy and do not create an entitlement to future refunds.

3.4 Termination by Leftoak Labs#

If we terminate your account or subscription without cause (i.e., not due to a violation of our Terms), we will refund the prorated portion of your current billing period.

4. Refunds for Voluntary Payments#

Voluntary Payments (such as tips) are made voluntarily, at your sole discretion, as expressions of appreciation. All Voluntary Payments are final and non-refundable, except as required by applicable law or in cases of processing error or unauthorized transaction (see Section 2).

5. Chargebacks#

If you initiate a chargeback or payment dispute through your bank or credit card provider instead of contacting us first, we reserve the right to suspend your access to the Services pending resolution. We encourage you to contact us at support@leftoak.com before initiating a chargeback so we can attempt to resolve the issue directly.

6. Your Rights Under Applicable Law#

Nothing in this Refund Policy limits any rights you may have under mandatory consumer protection laws in your jurisdiction. Where applicable law requires that refunds be made available under certain conditions, we will comply with those requirements.

If you believe you are entitled to a refund under the laws of your jurisdiction, please contact us at support@leftoak.com and we will work with you in good faith to resolve the matter.

7. How to Request a Refund#

To request a refund or report a payment issue, contact us at:

Leftoak Labs, LLC Email: support@leftoak.com

Please include the following information in your request:

• The email address associated with your account or payment (if applicable).
• The approximate date and amount of the transaction.
• The reason for your refund request.

We will acknowledge your request within a reasonable timeframe and aim to resolve refund requests promptly. Approved refunds are issued to the original payment method via Stripe. Processing times for the refund to appear on your statement may vary depending on your bank or card issuer.

8. Changes to This Refund Policy#

We may update this Refund Policy from time to time in our sole discretion. Material changes will be posted with a revised effective date, which shall constitute notice of such changes. Changes to refund terms do not apply retroactively to transactions completed before the updated effective date. Your continued use of the Services after the effective date of any updated refund terms constitutes your acceptance of the changes.

Addendum A: fretengine#

Application: fretengine — guitar instruction and practice tools URL: https://fretengine.com Addendum Effective Date: August 14, 2026

This addendum supplements the Leftoak Labs Refund Policy with terms specific to fretengine. Where this addendum conflicts with the general Refund Policy, this addendum governs for users of fretengine.

A.1 fretengine Payment Types#

fretengine currently accepts the following types of payments:

• Voluntary Tips: Optional gratuities to support the application (available to all users).
• Solo Plan Subscription: Monthly recurring payment for access to persistent sessions and workspace features.
• Navigator Plan Subscription: Monthly recurring payment for access to all Solo Plan features plus the AI music theory assistant.

A.2 Solo Plan Subscription Refunds#

The Solo Plan Subscription is billed monthly on a recurring basis. YOUR SUBSCRIPTION WILL CONTINUE AUTOMATICALLY UNTIL YOU CANCEL. The following refund terms apply:

• Cancellation: You may cancel at any time. Your subscription remains active through the end of the current billing period. No prorated refunds are issued for unused time. See Section 3.1 of the general Refund Policy.
• Satisfaction: If you are dissatisfied with the Solo Plan Subscription, contact us at support@fretengine.com. We evaluate refund requests on a case-by-case basis per Section 3.3 of the general Refund Policy.
• Service disruption: If a material service disruption prevents you from accessing paid features for a significant portion of your billing period, contact us and we will evaluate your refund request in good faith.

A.3 Navigator Plan Subscription Refunds#

The Navigator Plan Subscription is billed monthly on a recurring basis. YOUR SUBSCRIPTION WILL CONTINUE AUTOMATICALLY UNTIL YOU CANCEL. The following refund terms apply:

• Cancellation: You may cancel at any time. Your subscription remains active through the end of the current billing period. No prorated refunds are issued for unused time. See Section 3.1 of the general Refund Policy.
• AI service limitations: The AI assistant relies on third-party services and may occasionally be unavailable or produce inaccurate responses. Temporary AI service interruptions or the quality of individual AI responses do not constitute grounds for a refund, provided that the Service as a whole remains substantially available during your billing period.
• Satisfaction: If you are dissatisfied with the Navigator Plan Subscription, contact us at support@fretengine.com. We evaluate refund requests on a case-by-case basis per Section 3.3 of the general Refund Policy.
• Downgrade: If you downgrade from the Navigator Plan to the Solo Plan, the downgrade takes effect at the end of your current billing period. No prorated refund is issued for the tier difference. See Section 3.2 of the general Refund Policy.

A.4 Voluntary Tips Are Non-Refundable#

fretengine offers users the option to leave a voluntary tip to support the development and maintenance of the application. By making a tip, you acknowledge and agree to the following:

• Tips are voluntary. You are under no obligation to leave a tip. No feature, content, or level of service is conditioned on leaving a tip.
• Tips are non-refundable. Because tips are voluntary gratuities and not payments for goods or services, all tips are final and non-refundable, except as required by applicable law or in cases of processing error or unauthorized transaction (see Sections 2 and 6 of the general Refund Policy).
• Tips are accepted "as a thank you." A tip is an expression of appreciation for the application in its current state. Tips do not create any obligation on the part of Leftoak Labs to maintain, improve, or continue operating fretengine.

The non-refundable nature of tips is disclosed to you before you complete any tip transaction.

A.5 How to Report a Payment Issue#

If you experience a payment error (such as a duplicate charge or an unintended amount) when making any payment on fretengine, please contact us promptly at support@fretengine.com. We will investigate and correct any confirmed processing errors.
