Terms & Conditions

Please read these Terms & Conditions carefully before purchasing. By placing an order, you agree to the following:

1. Digital Products Only

All products sold through this website are digital in nature. This includes PDF notes, Excel spreadsheets, calculation examples, templates, and similar downloadable content.

2. No Refunds or Exchanges

Due to the digital and instantly accessible nature of the products, all sales are final. Once a file has been downloaded or accessed, it is considered consumed and non-refundable.

Please ensure you review the product descriptions and previews carefully before purchasing. If you have any questions before buying, feel free to reach out.

3. Intellectual Property

All content is copyrighted and for personal, individual use only. Redistribution, resale, or sharing of any material - whether in part or full - is strictly prohibited without written permission.

4. Spreadsheet Protection

The Excel spreadsheets offered are provided in a protected (locked) format. This is done to preserve the integrity of the product, prevent accidental modification, and protect the underlying structure, formulas, and intellectual property.

Each spreadsheet includes formatting that allows users to view certain formulas so the logic behind the calculations can be understood.

However, the protected spreadsheets cannot be unlocked or customised upon request.

These products are intended to be used as provided, either in their current format, as a learning resource, or as inspiration for developing your own tools.

If you require a fully editable version for your specific codes, units, or workflows, please consider whether the protected format aligns with your intended use before purchasing.

5. Product Access and Delivery

After successful payment, products will be made available for immediate download. A confirmation email will also be sent with access details.
