End User License Agreement

SHIELDAI END USER LICENSE AGREEMENT
EULA Version: 2026-08-05
Effective Date: August 5, 2026

IMPORTANT: PLEASE READ THIS AGREEMENT CAREFULLY. BY SELECTING "I AGREE," INSTALLING, ACCESSING, OR USING SHIELDAI, YOU AGREE TO THIS END USER LICENSE AGREEMENT ("EULA"). IF YOU DO NOT AGREE, DO NOT INSTALL OR USE SHIELDAI.

1. PARTIES AND PRODUCT

This EULA is between you ("you" or "User") and Express Tech Solutions ("Express Tech," "we," "us," or "our") and governs ShieldAI, including its Windows application, local security engine, browser extension, mobile companion, documentation, updates, threat-intelligence features, free features, paid features, and associated license and account services (collectively, the "Software").

2. LICENSE GRANT

Subject to this EULA and any plan-specific terms shown at purchase, Express Tech grants you a limited, revocable, nonexclusive, nontransferable license to install and use the Software for your personal or internal business security purposes. The Software is licensed, not sold. Express Tech and its licensors retain all rights not expressly granted.

3. ACCOUNTS, KEYS, AND DEVICE LIMITS

You must provide accurate account information and protect your credentials. Paid keys are issued to the purchasing account and may not be sold, transferred, published, or shared. Unless the applicable offer expressly states otherwise, a paid license may be registered to one computer at a time. Moving a license to a replacement computer requires a device reset by the Express Tech help desk. We may temporarily limit repeated failed key attempts and notify the registered account of suspected unauthorized use.

4. SECURITY SCOPE AND PROTECTION LAYERS

ShieldAI is a user-mode security and guidance product. It can analyze selected files, file hashes, supported archive contents, local risk indicators, monitored folder changes, certain process command lines, quarantine records, and supported web addresses. It does not install an unsigned kernel driver, does not control every operating-system security layer, and does not replace Windows Security, platform protections, backups, safe browsing practices, or professional incident response. Mobile operating systems limit access to other applications, so a mobile companion cannot perform unrestricted whole-device scanning.

5. NO COMPLETE-DETECTION GUARANTEE

Malware, phishing, unsafe software, and attacker methods change continuously. ShieldAI may miss a threat, identify a safe item as suspicious, provide incomplete reputation information, or become unavailable. A low-risk result does not prove that a file, process, archive, website, or device is safe. You must use reasonable judgment, keep operating-system and established security protections enabled and updated, and investigate important warnings before relying on a result.

6. SCANNING, MONITORING, QUARANTINE, AND USER APPROVAL

ShieldAI may watch configured folders and inspect files or process metadata needed to provide enabled protection features. Local file contents are not intentionally uploaded merely to perform the local risk analysis described by the product. Quarantine, restoration, deletion, remediation, and other consequential actions can interrupt software or cause data loss. Except for clearly disclosed automatic behavior you enable, ShieldAI requires your approval before moving an identified file into quarantine. You are responsible for reviewing detections and maintaining current backups before quarantine, deletion, restoration, remediation, or repair.

7. BROWSER SHIELD AND THREAT INTELLIGENCE

Browser Shield and live reputation features may compare supported domains, URLs, hashes, or indicators against intelligence supplied through the official Express Tech service. The current Browser Shield downloads reputation information and does not intentionally upload page contents, passwords, form entries, or complete browsing history. Intelligence can be delayed, unavailable, incomplete, or incorrect. Third-party sources remain governed by their own terms and availability.

8. FREE AND PAID FEATURES

The Software may include Free, trial, Premium, or Pro features. Paid access depends on successful payment, an active and valid license, the purchased term, account ownership, device limits, and verification by the official Express Tech license service. When a paid license expires, is refunded, is charged back, is disabled, or cannot be validated within an allowed offline period, the Software may return to Free mode. Local settings, history, and quarantine records are not intentionally deleted merely because paid access ends.

9. ACCEPTABLE USE AND RESTRICTIONS

You may not: (a) share or resell a license key; (b) bypass, defeat, probe, or interfere with account, payment, update, device-binding, threat-intelligence, or license-verification controls; (c) use ShieldAI to create, conceal, improve, distribute, or operate malware or to gain unauthorized access; (d) reverse engineer, decompile, or disassemble protected portions except where applicable law expressly permits it; (e) remove proprietary notices; (f) submit unlawful, infringing, or unauthorized data; or (g) overload or attack Express Tech systems.

10. USER DATA, BACKUPS, AND PRIVACY

ShieldAI stores core security state locally, including enabled protection settings, scan history, encrypted license-session information, device identity, and quarantine records. For a signed-in paid account, the ShieldAI guide sends only the user's question, recent guide conversation, app version, access tier, enabled-protection states, definition and model versions, scan-running state, and detection count to the Express Tech hosted AI service. It is designed not to send file contents, file paths, quarantine contents, browsing history, passwords, license keys, or remote-access codes through that assistant request. AI requests may be processed by Express Tech's contracted AI provider under applicable service terms. You are responsible for protecting device access and maintaining backups of important files. Removing ShieldAI, clearing application data, device failure, operating-system changes, or user action can remove local records. Online AI, account, license, support, security-notification, threat-intelligence, and optional analytics activity is handled as described in the Express Tech Privacy Policy at https://www.expresstechpc.com/privacy.

11. UPDATES AND ONLINE SERVICES

ShieldAI may connect only to designated Express Tech services for accounts, licensing, hosted guidance, updates, analytics you permit, and threat intelligence. Updates may add, change, repair, or remove features and may be required for security, compatibility, or continued access to online or paid features. We do not guarantee permanent availability of any feature, intelligence source, browser integration, operating-system capability, or third-party connection.

12. PURCHASES, RENEWALS, AND REFUNDS

Prices, term lengths, renewal behavior, taxes, included features, device limits, and refund eligibility are shown in the applicable offer, checkout, receipt, or written agreement. Payment processing may be provided by Square or another identified processor. Activated software, completed terms, and delivered digital licenses may have restricted refund eligibility to the extent permitted by law.

13. SUSPENSION AND TERMINATION

This license ends when its purchased term ends or when this EULA is terminated. Express Tech may suspend or terminate paid or online access for refund, chargeback, fraud, unlawful use, shared or transferred keys, attacks on the service, material breach, or a security risk. On termination, you must stop using paid features and may need to uninstall the Software. Provisions concerning ownership, restrictions, disclaimers, liability, and governing law survive termination.

14. OWNERSHIP

ShieldAI, Browser Shield, related names, interfaces, original code, detection logic, documentation, branding, and service components are owned by Express Tech or its licensors and are protected by intellectual-property law. Third-party components and intelligence remain subject to their respective licenses and notices.

15. DISCLAIMER OF WARRANTIES

TO THE FULLEST EXTENT PERMITTED BY LAW, THE SOFTWARE AND ONLINE SERVICES ARE PROVIDED "AS IS" AND "AS AVAILABLE." EXCEPT FOR ANY EXPRESS WRITTEN WARRANTY, EXPRESS TECH DISCLAIMS IMPLIED WARRANTIES, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT. WE DO NOT GUARANTEE COMPLETE THREAT DETECTION, ERROR-FREE RESULTS, UNINTERRUPTED PROTECTION, SUCCESSFUL REMEDIATION, PERMANENT DATA STORAGE, OR THAT A FILE, WEBSITE, PROCESS, OR DEVICE IS SAFE. SOME JURISDICTIONS DO NOT ALLOW CERTAIN DISCLAIMERS, SO SOME OF THESE TERMS MAY NOT APPLY TO YOU.

16. LIMITATION OF LIABILITY

TO THE FULLEST EXTENT PERMITTED BY LAW, EXPRESS TECH WILL NOT BE LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, EXEMPLARY, PUNITIVE, OR CONSEQUENTIAL DAMAGES, OR FOR LOST PROFITS, LOST BUSINESS, SECURITY INCIDENTS, SYSTEM DOWNTIME, OR LOST OR CORRUPTED DATA ARISING FROM THE SOFTWARE. TO THE EXTENT A DIRECT-LIABILITY LIMIT IS PERMITTED, EXPRESS TECH'S TOTAL LIABILITY ARISING FROM THE SOFTWARE WILL NOT EXCEED THE AMOUNT YOU PAID EXPRESS TECH FOR THE APPLICABLE SHIELDAI LICENSE DURING THE TWELVE MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM. NOTHING IN THIS EULA EXCLUDES LIABILITY THAT CANNOT LEGALLY BE LIMITED.

17. GOVERNING LAW AND GENERAL TERMS

This EULA is governed by the laws of the State of Ohio, without regard to conflict-of-law rules. If a provision is unenforceable, the remaining provisions remain effective. Failure to enforce a provision is not a waiver. You may not assign this EULA without written permission. Express Tech may assign it as part of a lawful business transfer. This EULA, the Express Tech Legal Terms, Privacy Policy, and any purchase-specific written terms form the agreement governing the Software; purchase-specific written terms control if they directly conflict with this EULA.

18. CHANGES TO THIS EULA

We may update this EULA prospectively when ShieldAI, security requirements, services, or law change. The Software may require you to review and accept a new version before continued use. The version and effective date identify the agreement you accepted.
