End User License AgreementL3 SimGuard  ·  Last updated: 2026-05-25  ·  Effective: 2026-05-25

This End User License Agreement ("Agreement") is a binding contract between you ("you" or "User") and the Licensor identified below, governing your installation and use of L3 SimGuard (the "Software"). By installing, copying, or otherwise using the Software, you agree to be bound by this Agreement. If you do not agree, do not install or use the Software.

1. Parties

Licensor:

Simulatortechnik Reinemuth
George-Washington-Str. 221
68309 Mannheim
Germany

E-Mail: contact@land3simulations.com

2. Definitions

  • Software means the L3 SimGuard client application (L3SimGuard.exe), its installer, updater, and all bundled components.
  • Protected Add-on means a third-party flight simulator add-on whose files are encrypted with the L3DRM protection system and require the Software to be readable at runtime.
  • Kernel Component means the kernel-mode file system filter driver installed alongside the Software, as further described in Section 4.
  • Update means any patch, hotfix, new version, or modified Kernel Component delivered by Licensor through the Software's update mechanism.

3. Grant of License

Subject to your compliance with this Agreement, Licensor grants you a personal, non-exclusive, non-transferable, non-sublicensable, revocable license to install and use the Software on machines you own or control, solely for the purpose of accessing Protected Add-ons that you have lawfully licensed. No rights are granted by implication, estoppel, or otherwise.

4. Kernel-Level Component

The Software installs a kernel-mode file system filter driver (the "Kernel Component") supplied by a third-party vendor. The Kernel Component operates with elevated system privileges and is required to mediate access to encrypted Protected Add-on files at runtime. The Kernel Component is loaded by the Windows operating system during normal operation of the Software and remains installed until you uninstall the Software.

Information about the current third-party component (including vendor and version) is listed in the Software under About → Third-Party Notices. Licensor may, at its sole discretion and without prior notice, replace the Kernel Component with an equivalent component from another vendor by means of an Update.

By installing the Software you expressly consent to the installation, loading, and operation of the Kernel Component on your system.

5. Automatic Updates

The Software periodically contacts Licensor's update servers over HTTPS and may automatically download and install Updates to the Software and to the Kernel Component without further user interaction. Updates may add, modify, or remove features and may include security or anti-tamper changes. This Agreement applies to all Updates unless an Update is accompanied by a separate agreement, in which case the separate agreement controls.

Security updates, integrity updates, and updates required to maintain conformity of the Software with this Agreement (including updates to the Kernel Component required to keep the Software operational on supported Windows versions) are mandatory and cannot be declined separately; you may decline them only by uninstalling the Software. Feature updates that go beyond what is necessary for conformity may be declined by not installing them, to the extent technically possible. Continued use of the Software after an Update has been installed constitutes acceptance of that Update.

6. License Validation, Activation, and Telemetry

The Software contacts Licensor's servers to validate licenses, refresh activation state, deliver Updates, and report integrity and tamper events. Data transmitted is limited to what is necessary for these purposes (including a device identifier, installation and version information, and integrity event records). The Software does not transmit the contents of your Protected Add-ons or your personal files.

The Software additionally collects technical crash and error reports through a third-party service (Sentry) to maintain stability and security. You can disable this at any time in Settings → General → Disable crash reporting.

For details on the handling of personal data, see our Privacy Policy.

7. Restrictions

You shall not, and shall not permit any third party to:

  • reverse engineer, decompile, disassemble, or otherwise attempt to derive the source code, algorithms, or protocols of the Software, the Kernel Component, or the L3DRM protection system, except to the extent such restriction is prohibited by applicable mandatory law;
  • circumvent, disable, tamper with, or interfere with any security, anti-tamper, license-enforcement, or update mechanism of the Software;
  • extract, decrypt, copy, modify, or redistribute decrypted assets of any Protected Add-on;
  • remove, alter, or obscure any proprietary, copyright, or attribution notices;
  • use the Software in any environment, virtualization, or configuration designed to evade license or integrity checks;
  • rent, lease, lend, sell, sublicense, distribute, or otherwise transfer the Software to any third party.

8. Intellectual Property

The Software, including the L3DRM protection system, all bundled binaries, and all related materials, is licensed and not sold. Licensor and its licensors retain all right, title, and interest in and to the Software, including all intellectual property rights. All rights not expressly granted to you in this Agreement are reserved.

9. Termination

This Agreement and the license granted hereunder terminate automatically and without notice if you breach any of its terms. You may terminate this Agreement at any time by uninstalling the Software via Settings → Installed apps → L3 SimGuard. Upon termination, you must cease all use of the Software. Once the Software is removed, Protected Add-ons will no longer be accessible until the Software is reinstalled.

10. Disclaimer of Warranty

To the maximum extent permitted by applicable law, the Software is provided "AS IS" and "AS AVAILABLE", with all faults and without warranty of any kind, whether express, implied, statutory, or otherwise, including any implied warranties of merchantability, fitness for a particular purpose, title, and non-infringement. Licensor does not warrant that the Software will be uninterrupted, error-free, or compatible with any particular hardware, software, or add-on.

11. Limitation of Liability

To the maximum extent permitted by applicable law, Licensor's total cumulative liability arising out of or relating to this Agreement or the Software shall not exceed the amounts (if any) actually paid by you to Licensor for the Software during the twelve (12) months preceding the event giving rise to the claim. In no event shall Licensor be liable for any indirect, incidental, special, consequential, or punitive damages, or for any loss of profits, revenue, data, or use.

Nothing in this Agreement excludes or limits Licensor's liability for damages arising from injury to life, body, or health, for intent or gross negligence, for breach of material contractual obligations (Kardinalpflichten / wesentliche Vertragspflichten), under the German Product Liability Act (Produkthaftungsgesetz), or any other liability that cannot be excluded or limited under mandatory applicable law. In case of slightly negligent breach of a material contractual obligation, liability is limited to the foreseeable damage typical for this type of contract.

12. Governing Law and Jurisdiction

This Agreement is governed by the laws of the Federal Republic of Germany, excluding the United Nations Convention on Contracts for the International Sale of Goods (CISG) and excluding conflict-of-laws rules. To the extent permitted by law, the exclusive place of jurisdiction for all disputes arising out of or in connection with this Agreement is Mannheim, Germany. Mandatory consumer venue and jurisdiction rules remain unaffected.

Nothing in this Agreement limits any rights you may have under mandatory consumer protection laws of your country of residence.

13. Changes to This Agreement

Licensor may modify this Agreement from time to time. Material changes will be notified to you by an in-application message, by email (where applicable), or by publication on this page with an updated "Last updated" date, in each case at least six (6) weeks before the changes take effect. You may reject the changes within that six-week period by uninstalling the Software or by giving notice to the contact address below; in that case the Agreement continues under the prior terms until you stop using the Software. If you do not reject the changes within the six-week period and continue to use the Software after the effective date, the modified Agreement applies.
