END USER LICENSE AGREEMENT (EULA)

Last Updated: 23.02.26

Please read this Agreement carefully. This document is a legal contract governing your rights and obligations regarding all products and services you access, download, or license through the platform with the domain name “market.ravencorp.space” (“Zadax Store”), operated by [Full Corporate Title to be Inserted] (hereinafter referred to as “Zadax”).

By becoming a member of the Zadax Store, adding a Product to your library, or clicking the "I Accept" button, you declare and undertake that you are bound by the terms of this Agreement. If you do not agree to the terms of this Agreement, you must not access the Zadax Store and must not use the services.

This Agreement constitutes a whole with the Privacy Policy (LINK) and Terms of Service (LINK). In the event of a conflict between the texts, the provisions of this EULA shall prevail primarily regarding License and Product usage.

1. Grant of License

1.1 Standard License for Software

Zadax enables you to add Products offered by Developers to your library. Each addition is considered a “Transaction.”

(a) Nature of the License: Products are not sold to the user; unless otherwise specified in the Software-Specific Terms, they are granted as a worldwide, non-exclusive, non-transferable, and personal-use-only license. This license does not grant any ownership or title to the Product.
(b) Accessibility and Interruption: Products may be removed from the platform based on the Developer’s request, intellectual property infringement claims, or Zadax’s technical/administrative decisions. Zadax does not guarantee the continuity of external links provided, particularly through third-party platforms (GitHub, Google Drive, etc.), nor that these links will always remain accessible, virus-free, or secure.
(c) Archiving and Storage: Zadax reserves the right to store a copy of the Products on its own servers for technical continuity, security audits, or system backup purposes. However, this does not imply an obligation for Zadax to make the Product re-accessible to the User or provide uninterrupted download possibilities if the Product is taken down by the Developer or the relevant external platform.

1.2 Developer License and Special Terms

Some Products may be subject to additional or alternative license terms (“Software-Specific Terms”) determined by the Developer. In such cases:

(a) Order of Precedence: In the event of any conflict or inconsistency between the Software-Specific Terms and the provisions of this Agreement (EULA), the provisions of this Agreement shall prevail primarily on matters protecting Zadax’s rights, limiting its liability, or regulating the User’s obligations.
(b) Capacity of Parties: Software-Specific Terms are exclusively between the User and the Developer. Unless Zadax offers the Product in the capacity of the Developer itself, it is not a party, guarantor, or liable party for these special terms.
(c) Default Status: If no "Software-Specific Terms" are provided by the Developer, the User agrees that the Standard License provisions specified in Article 1.1 shall apply.

2. License Conditions and Restrictions

You may not use the Products or any part of the Services in the following ways or for the following purposes:

(a) Device Limit: You may not use the Products or Services on more than one device simultaneously, unless otherwise specified in the Software-Specific Terms.
(b) Copying and Reproduction: You may not copy, reproduce, publicly display, or use the Products unlawfully in any manner not expressly permitted in this Agreement or the Software-Specific Terms.
(c) Commercial Disposition: You may not sell, rent, lease, lend, sub-license, or transfer your rights arising from this Agreement for any commercial purpose without the prior written consent of Zadax.
(d) Technical Interference and Reverse Engineering: You may not reverse engineer, extract source code, decompile, or change the core operational logic of the product. The modification of variables by the user through the input fields provided in calculation tools (spreadsheets, scripts, etc.) is outside this prohibition; however, interfering with the formulas, macros, algorithms, or protected cells where these variables are processed is strictly prohibited.
(e) Security and Cheating: You may not remove security measures, digital rights management (DRM) systems, or protection labels on the Product or Services; nor may you use unauthorized software that provides an unfair advantage (cheats, bots, automation, etc.).
(f) Intellectual Property and Legislation: You may not infringe upon third-party rights (copyright, trademark, trade secret, etc.) or use the products in violation of applicable laws and regulations (including export control laws).
(g) Platform Code of Ethics: You may not engage in behaviors that, at Zadax’s discretion, would negatively affect the experience of other users (harassment, profanity, sabotage, spam, fraud, misleading content, etc.).
(h) Data Mining and AI: You may not collect Product content or data from the Zadax Store through robots, spiders, or other automated tools (scraping), nor use this data for training artificial intelligence models or developing competing products.
(i) Prohibition of Off-Platform Transactions: You may not contact the Developer through non-Zadax channels or conduct payment processes outside the platform for the purpose of moving Product-related transactions off-platform or bypassing Zadax’s intermediary role.
