1. Overview

These Terms and Conditions govern your purchase and use of software products sold through shop.modeltok.com ("the Store"), operated by Bartłomiej Tokarzewski, a sole proprietor based in Poland ("ModelTok", "we", "us").

By purchasing or using our products, you agree to these terms.

2. Products

We sell desktop software applications for engineering and building science. Each product listing specifies its features, supported platforms, and pricing.

We also provide web browser versions of some products (accessible without installation). These web applications may be discontinued or significantly modified at any time. We will provide at least 7 days' written notice via email before discontinuing any web application or changing its URL. During the notice period, the application will remain fully functional at the current URL. Your access to web versions is not guaranteed to remain available indefinitely.

Web applications are provided "as-is" without guarantee of uptime, availability, or uninterrupted service. We are not liable for any service interruptions, data loss, or unavailability of web applications.

Software is delivered digitally. After purchase, you will receive download links via email or through your account. Delivery is immediate upon successful payment.

6. Updates

One-time purchases include free updates for the major version purchased (e.g., purchasing v1.x entitles you to all 1.x updates). Major version upgrades may require a separate purchase at a discounted rate.

7. Disclaimer of Warranties

The software is provided "as is" without warranty of any kind, express or implied, including but not limited to the warranties of merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that the software will be error-free or uninterrupted.
