Effective date: September 12, 2026

These Terms and Conditions govern your access to and use of the Quantum Simple store and your purchase and use of its digital products. By accessing this store or completing a purchase, you agree to these terms.

1. Digital Products

Quantum Simple sells downloadable digital products for personal, educational, and informational use. Products are delivered electronically; no physical item will be shipped unless a product listing expressly states otherwise.

1. Personal-Use License

Your purchase grants you a limited, non-exclusive, non-transferable, revocable license to download and use the purchased product for your own personal use.

You may not:

• Copy, reproduce, resell, redistribute, share, sublicense, or give the product to another person

• Upload the product to a public website, file-sharing service, marketplace, or shared drive

• Modify or repackage the product for resale

• Claim the product or its contents as your own

• Use the product to create a competing product based substantially on its content

All rights not expressly granted remain with Quantum Simple and the applicable copyright owner.

1. Payments

Prices are displayed before checkout. Payments are processed through Payhip and its connected payment providers. You agree to provide accurate billing and contact information and authorize the applicable payment provider to charge the amount shown at checkout.

Applicable taxes may be added or handled during checkout according to your location and relevant law.

1. Delivery

After successful payment, access to the digital product is normally provided through the checkout confirmation page and purchase-confirmation email.

You are responsible for providing a valid email address and maintaining a compatible device and software capable of opening the product.

If you experience a delivery or download problem, please contact us through the Contact page.

1. Refunds

Because digital products are delivered electronically and access is generally provided immediately, purchases are subject to the Refund Policy displayed on this website. Nothing in these terms limits any non-waivable consumer rights provided by applicable law.

1. Educational Information and No Earnings Guarantee

The products and website content are provided for general educational and informational purposes only. They do not constitute financial, investment, legal, tax, business, or professional advice.

Quantum Simple does not promise or guarantee income, profit, business growth, or any particular result. Outcomes vary and depend on factors including your decisions, effort, experience, skills, resources, market conditions, and compliance with applicable laws.

You are responsible for evaluating each idea and obtaining qualified professional advice when appropriate.

1. Intellectual Property

The store design, branding, text, graphics, product content, and other original materials are protected by copyright, trademark, and other intellectual-property laws. You may not use these materials except as permitted by these terms or with prior written permission.

1. Acceptable Use

You may not misuse the store, interfere with its operation, attempt unauthorized access, commit fraud, introduce malicious code, violate another person’s rights, or use the store or its products for unlawful purposes.

1. Third-Party Services

The store may rely on or link to third-party services, including Payhip and payment providers. Quantum Simple does not control those services, and your use of them may also be governed by their own terms and policies.

1. Product Availability and Changes

We may update, correct, replace, suspend, or discontinue products or website content when reasonably necessary. We may also correct pricing, description, or typographical errors. Changes will not remove rights already required by applicable consumer law.

1. Disclaimer

To the fullest extent permitted by law, the store and its products are provided “as is” and “as available,” without warranties beyond those that cannot legally be excluded.

1. Limitation of Liability

To the fullest extent permitted by law, Quantum Simple will not be liable for indirect, incidental, special, consequential, or lost-profit damages arising from your use of the store or its products.

Where liability cannot be excluded, total liability relating to a purchase will not exceed the amount you paid for that specific product, except where applicable law requires otherwise.

1. Termination

Access may be limited or terminated if you violate these terms, misuse a product, engage in fraud, or infringe intellectual-property rights. Provisions concerning licenses, intellectual property, disclaimers, and liability will continue where applicable.

1. Changes to These Terms

These Terms and Conditions may be updated periodically. The revised version will be posted on this page with an updated effective date. Terms applicable at the time of purchase will continue to govern that purchase unless applicable law requires otherwise.
