Emrelia E3X — End User License Agreement

Last updated September 2026

Licensor: Emrelia LLC, a Colorado limited liability company, United States ("Emrelia", "we").
Software: the Emrelia E3X flight-simulation avionics software, including its simulator plugins, bundled browser runtime, documentation, updates, and any data packs we make available for it (together, the "Software").

By installing, activating, or using the Software you agree to this Agreement. If you do not agree, do not install it, and request a refund under §11 within the refund window.

1. Simulation use only — read this first

The Software is entertainment and desktop-simulation software. It is not an avionics product, is not certified or approved by any aviation authority, and must never be used for real-world navigation, flight planning, weather decisions, terrain or traffic avoidance, or any other operational aviation purpose. Aeronautical data presented by the Software may be incomplete, out of date, or wrong. You accept that any resemblance to certified equipment is for realism in simulation only.

2. Definitions

  • "Activation" is the process by which the Software registers a license key against a Machine through our license service.
  • "Machine" is one physical computer identified by a machine identifier the Software derives from that computer's hardware or operating system.
  • "License Key" is the key issued to you on purchase (or on our behalf by our merchant of record).
  • "Personal Use" is use by you, an individual, for your own entertainment, hobby, or private practice, and not for or on behalf of any business, school, organisation, or paying customer.

3. License grant

Subject to this Agreement and payment of the applicable fee, Emrelia grants you a personal, non-exclusive, non-transferable, revocable license to:

(a) install and use the Software for Personal Use;

(b) activate and use it on up to the number of Machines shown at purchase (currently two) that you own or control, at the same time;

(c) move an activation from one Machine to another by deactivating it on the old Machine, or, where that Machine is no longer available to you, from your account at emrelia.com, subject to the reasonable limits on the frequency of such moves that we publish and enforce there; moves beyond those limits are handled by support at [email protected]; and

(d) make one copy of the installer for backup.

The Software is licensed, not sold. We and our licensors keep all rights not expressly granted.

4. What you may not do

You may not, and may not let anyone else:

(a) use the Software for anything other than Personal Use — including in a flight school, training centre, simulator centre, club, or any commercial, paid, or organisational setting, in any device offered as or represented to be an aviation training device, or in any paid instruction — without a separate written agreement with Emrelia (write to [email protected]);

(b) use the Software for any real-world aviation purpose (see §1);

(c) copy, distribute, sell, resell, rent, lease, lend, sublicense, or otherwise transfer the Software, a License Key, or an activation to anyone else, or make the Software available over a network to others;

(d) share a License Key, or activate it on Machines you do not own or control;

(e) circumvent, disable, or interfere with activation, license checks, or any technical measure in the Software, or use a License Key you were not issued;

(f) reverse engineer, decompile, disassemble, or attempt to derive the source code of the Software, except to the extent applicable law expressly allows this despite this limitation;

(g) modify the Software or create derivative works of it, except for configuration files the Software documents as user-editable;

(h) remove or alter any proprietary notice, trademark, or attribution; or

(i) use the Software in violation of any law, or of the terms of the simulator or third-party products you use it with.

5. Activation, license checks, and the data involved

(a) The Software requires Activation before it will connect to a flight simulator. Without Activation it runs only in its demonstration and replay modes.

(b) On Activation, and occasionally afterwards when an internet connection is available, the Software sends our license service your License Key, a machine identifier and the computer's name, the Software version, and the operating system. We use this only to enforce the activation limit, to service your account, and to detect abuse. The Software does not need an internet connection to start once activated, and does not send flight or usage data. See our Privacy Policy.

(c) If a License Key is refunded, found to be shared or fraudulently obtained, or deactivated from your account, the Software returns to its unactivated state.

6. Data packs and third-party components

(a) The Software presents aeronautical, terrain, map, and weather data obtained from government and open sources. That data is provided under its own licenses and attribution requirements, listed at data attributions and in the notices shipped with the Software; those notices are part of this Agreement. Some derived data stores are available on request under share-alike terms as described at corresponding source.

(b) Data has publication cycles. Data packs may be out of date at any time, and we do not promise updates on any schedule.

(c) The Software includes open-source components, including a bundled Chromium browser runtime, listed in the THIRD-PARTY NOTICES file shipped with it. Those components are licensed under their own terms, which apply to them instead of this Agreement where the two conflict.

(d) The Software connects to third-party flight simulators and may read from and write to them. We are not responsible for those products, and their terms govern your use of them.

7. Updates

We may provide updates, which may add, change, or remove features. Updates are covered by this Agreement unless they come with different terms. We have no obligation to provide updates or support, though we will try to be helpful at [email protected].

8. Ownership; feedback

The Software, its design, and its documentation are the property of Emrelia LLC and are protected by copyright and other laws. If you send us suggestions or feedback, you grant us a perpetual, royalty-free right to use them without obligation to you.

9. Trademarks and non-affiliation

Emrelia E3X is an independent product of Emrelia LLC. It is not affiliated with, endorsed by, sponsored by, or otherwise connected with Garmin Ltd. or its affiliates. G3X Touch™ and other Garmin marks are trademarks of Garmin Ltd., used only to describe compatibility and inspiration. X-Plane, Microsoft Flight Simulator, RealSimGear, RealityXP, Navigraph, and other names are the property of their respective owners. This Agreement grants you no right to use any trademark.

10. Term and termination

This Agreement lasts until terminated. It terminates automatically if you breach it. We may also terminate or suspend a License Key that we reasonably believe has been shared, resold, refunded, obtained fraudulently, or used in breach of §4. On termination you must stop using the Software and delete your copies; §§1, 4, 8, 9, 12, 13, and 15 survive.

11. Purchases and refunds

Purchases are processed by our merchant of record, Lemon Squeezy, whose terms of sale apply to the transaction. Our refund policy is at emrelia.com/legal/refunds: request a refund within 14 days of purchase and we will issue it. Refunded License Keys are deactivated.

12. Disclaimer of warranties

THE SOFTWARE AND ALL DATA ARE PROVIDED "AS IS" AND "AS AVAILABLE", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING ANY WARRANTY OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, ACCURACY, NON-INFRINGEMENT, OR THAT THE SOFTWARE WILL BE ERROR-FREE OR WORK WITH ANY PARTICULAR SIMULATOR, HARDWARE, OR OPERATING SYSTEM. NOTHING IN THE SOFTWARE IS A REPRESENTATION ABOUT THE REAL WORLD. Some jurisdictions do not allow the exclusion of implied warranties, so parts of this section may not apply to you.

13. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, EMRELIA LLC AND ITS SUPPLIERS ARE NOT LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR LOST DATA, LOST PROFITS, OR LOSS OF USE, ARISING OUT OF OR RELATED TO THE SOFTWARE OR THIS AGREEMENT, HOWEVER CAUSED. OUR TOTAL LIABILITY FOR ALL CLAIMS IS LIMITED TO THE AMOUNT YOU PAID FOR THE SOFTWARE IN THE TWELVE MONTHS BEFORE THE CLAIM. Nothing in this Agreement limits liability that cannot be limited by law.

14. Export and sanctions

You may not use or export the Software in violation of applicable export control or sanctions laws, and you represent that you are not located in a jurisdiction subject to comprehensive sanctions and are not on any government restricted-party list.

15. General

(a) Governing law and venue. This Agreement is governed by the laws of the State of Colorado, United States, without regard to conflict-of-laws rules. Any dispute will be brought in the state or federal courts located in Colorado, and you consent to their jurisdiction. If you are a consumer, nothing in this Agreement removes protections you have under the mandatory law of your country of residence.

(b) Entire agreement. This Agreement, the notices it references, the Privacy Policy, and the refund policy are the entire agreement about the Software and replace any prior understanding.

(c) Changes. We may update this Agreement for new versions of the Software. The version shipped with, or accepted on activation of, the copy you use is the one that applies to it.

(d) Severability; waiver. If any part of this Agreement is unenforceable, the rest still applies. Not enforcing a provision is not a waiver of it.

(e) Assignment. You may not assign this Agreement or the license. We may assign it to a successor of the business.

(f) Contact. Emrelia LLC — [email protected].
