(applicable to internal and external users of XENIOS BLOCKCHAIN GROUP S.A. digital systems and products)

This document sets forth the Terms of Use governing access to and utilization of all software platforms, systems, and digital products owned, developed, or operated by XENIOS BLOCKCHAIN GROUP S.A., a company duly organized and existing under the laws of Greece, with registered office at 17th Noemvriou 4B, Melissia, Athens, VAT 802248144, G.E.MI. 160986401000, hereinafter referred to as “XENIOS” or the “Company”. By accessing or using any XENIOS platform, application, or service, each individual or entity (hereinafter the “User”) acknowledges and agrees to be bound by these Terms of Use.

These Terms apply to all internal users (employees, contractors, consultants) and external users (clients, partners, vendors, white-label licensees, and end-users) who access, use, or interact with any product, software, or information system developed or maintained by XENIOS, including but not limited to the tBox platform and related technological infrastructures.

Access to XENIOS systems is granted exclusively for legitimate business, operational, or contractual purposes, in accordance with the user’s role and authorization level. Users shall utilize the systems solely in the manner expressly permitted by XENIOS and strictly in compliance with applicable laws, company policies, and data-protection requirements. Unauthorized or improper use, including access beyond granted rights, alteration or copying of source code, data extraction, or circumvention of technical controls, is strictly prohibited.

All intellectual and industrial property rights, including but not limited to copyrights, trademarks, domain names, software code, algorithms, documentation, designs, and trade secrets related to XENIOS products and technologies, remain the exclusive property of XENIOS BLOCKCHAIN GROUP S.A. or its licensors. Nothing in these Terms shall be interpreted as transferring or granting any ownership right to the User. Any reproduction, modification, redistribution, or commercialization of XENIOS intellectual property without prior written consent constitutes a material breach and may result in civil and criminal liability under applicable law. White-label clients are granted only a non-exclusive, revocable, and limited license to use the platform under their own brand, strictly within the parameters set forth in their contractual agreement.

Users acknowledge that during access to XENIOS systems they may encounter confidential, proprietary, or personal information. All such information must be treated as strictly confidential and may not be disclosed or used for any purpose other than that for which access was granted. Users are obliged to comply with the Company’s Data Protection Policy, internal Security and Privacy Framework, and all relevant laws including the EU General Data Protection Regulation (GDPR). In case of doubt, users must seek written clarification from the Company’s Legal or Compliance Department before proceeding with any processing of personal data.

Each User shall maintain the confidentiality of login credentials, use secure passwords, and immediately report any suspicion of unauthorized access or data breach. Users must refrain from introducing malware, disabling security features, attempting to reverse engineer the software, or using Company systems in a way that could harm the integrity, security, or reputation of XENIOS. Users are responsible for any action performed under their assigned credentials and for compliance with internal IT and Security policies.

XENIOS reserves the right to monitor, log, and audit system activity for purposes of ensuring security, compliance, and operational integrity. All such monitoring shall comply with applicable data-protection law and internal privacy standards. Users hereby acknowledge and consent to the lawful monitoring of their activities within XENIOS platforms.

Any misuse or violation of these Terms may result in immediate suspension or termination of access rights, disciplinary action for internal users, and legal or contractual remedies for external users, including termination of agreements, claims for damages, and reporting to competent authorities. XENIOS retains the right to seek compensation for any direct or indirect loss caused by non-compliance with these Terms.

To the maximum extent permitted by law, XENIOS shall not be liable for any indirect, incidental, or consequential damages arising out of or in connection with the use or inability to use its systems or products. XENIOS does not guarantee that its platforms will be error-free or continuously available but undertakes to maintain commercially reasonable standards of uptime and cybersecurity as specified in the applicable SLA or service agreement.

Where XENIOS products interface with external APIs, services, or networks, XENIOS shall not be responsible for the content, policies, or practices of such third parties. Users are advised to review the privacy and terms of such external services before enabling integration. Any third-party software or component included within XENIOS systems remains subject to its respective license conditions.

XENIOS reserves the right to revoke or suspend a User’s access at any time, with or without notice, if deemed necessary for the protection of its systems, clients, or legal compliance. Upon termination, the User must immediately cease using all systems and return or destroy any confidential materials in their possession.

These Terms shall be governed by and construed in accordance with the laws of Greece and the applicable provisions of European Union law. Any dispute arising from or related to these Terms shall fall under the exclusive jurisdiction of the competent courts of Athens, Greece.

If any provision of these Terms is found to be invalid or unenforceable, the remaining provisions shall remain in full force and effect. XENIOS may amend these Terms from time to time; users will be duly informed of material changes. Continued use of the systems after such notification constitutes acceptance of the revised Terms.
