At KnowlexBooks, all of our products are delivered digitally. Once your payment is confirmed, your files will be available for instant download.
Because these are digital products, they cannot be returned like physical items, and for this reason, all sales are generally considered final and nonrefundable.

However, you may be eligible for a refund within 14 days of your purchase under one of the limited circumstances listed below:

Eligibility for Refund

You may request a refund if:

• File Download Status – You purchased a product but were never able to download the file.

• Duplicate Purchase – You accidentally purchased the same resource more than once.

• Compromised File – The file is corrupted, missing content, or incomplete.

• Technical Limitations – You are unable to access the file because technical requirements were not clearly listed or were inaccurate in the product description.

If your situation meets one of the conditions above, please contact us within 14 days of your purchase to request a refund.

How to Request a Refund

To request a refund, please email us at contact@knowlexbooks.shop and include:

• Your order number

• The product name

• A brief description of the issue

We review all requests carefully and aim to respond within 24 hours.

Please note: Refunds will not be granted for reasons such as changing your mind, purchasing the wrong product by mistake, or failure to read the product description before purchase.
