End User License Agreement

1. Ownership and License

QuextFlight is a wholly owned brand of Quext Interactive Technologies, Inc. ("Quext Interactive," "we," "us," or "our"). Quext Interactive retains all right, title, and interest in and to the Software, including all associated intellectual-property rights.

Subject to your compliance with this Agreement and any applicable subscription requirements, Quext Interactive grants you a limited, revocable, non-exclusive, non-transferable, non-sublicensable license to use the Software for your personal or authorized aviation planning, training, and operational-awareness purposes. The Software is licensed, not sold.

2. Informational and Advisory Use Only

The Software is provided for informational and advisory purposes only. It is not a substitute for current official aeronautical information, notices, charts, weather products, aircraft flight manuals, required inspections, pilot judgment, or compliance with applicable laws, regulations, operating limitations, and procedures.

The pilot in command is the final authority as to the safe operation of the aircraft. QuextFlight must never be used as a replacement for sound aeronautical judgment, as a means of navigation, for flying an approach, or as a means to violate or avoid compliance with any Federal Aviation Regulations.

You are solely responsible for verifying all information used for a flight, determining the airworthiness and suitability of the aircraft and equipment, obtaining and reviewing current official sources, and making all operational decisions. You must not rely on the Software as the sole source of information for any flight decision.

3. No Warranty; Information May Be Incomplete or Expired

THE SOFTWARE AND ALL INFORMATION MADE AVAILABLE THROUGH IT ARE PROVIDED "AS IS" AND "AS AVAILABLE." QUEXT INTERACTIVE MAKES NO GUARANTEE, REPRESENTATION, OR WARRANTY THAT THE SOFTWARE OR ANY DATA, CONTENT, CALCULATION, ALERT, CHART, WEATHER PRODUCT, NOTAM, PROCEDURE, AIRPORT DETAIL, TERRAIN OR OBSTACLE INFORMATION, OR OTHER INFORMATION IS COMPLETE, ACCURATE, CURRENT, AVAILABLE, ERROR-FREE, OR SUITABLE FOR A PARTICULAR PURPOSE.

Information in the Software may be missing, omitted, incorrect, delayed, unavailable, superseded, or expired. To the maximum extent permitted by law, Quext Interactive disclaims all express, implied, and statutory warranties, including warranties of merchantability, fitness for a particular purpose, title, non-infringement, accuracy, completeness, reliability, and uninterrupted availability.

Third-party information and services may be public, licensed, proprietary, confidential, copyrighted, trademarked, protected by database rights, or subject to contractual, privacy, security, attribution, access, or rate-limit restrictions. Government-originated information is not necessarily free of all restrictions: source-specific terms, notices, and markings control. You receive no ownership interest or independent license in third-party material beyond the limited right to view and use it through the normal, intended operation of the Software.

You may use third-party information made available through QuextFlight solely for your personal or otherwise authorized aviation planning, training, and operational-awareness purposes, and only through the Software's intended interfaces.

You must comply with all applicable provider terms, notices, licenses, and laws. The list above may change as providers, products, or features change; we may update this Agreement to reflect those changes.

Third-party information is supplemental and must not be treated as an official source, a replacement for required preflight or in-flight information, or a basis to disregard current official publications, NOTAMs, weather products, regulations, aircraft limitations, or pilot judgment.
