OPENJSQ END-USER LICENCE AGREEMENT
Version 1.0 - 12 October 2026
Copyright (c) 2026 Jerome Goddard II (W4IJG). All rights reserved.

Please read this agreement before installing or using OpenJSQ. By installing,
copying or using OpenJSQ you agree to it. If you do not agree, do not install
or use OpenJSQ.

1. WHO THIS AGREEMENT IS BETWEEN

This agreement is between you and Jerome Goddard II (W4IJG) ("the Author").
"OpenJSQ" means the OpenJSQ software in executable form, its installer, its
documentation and any updates the Author provides. "You" means the person who
installs or uses it, or the nonprofit organisation on whose behalf they do.

2. WHAT YOU MAY DO

The Author grants you a free, non-exclusive, non-transferable, revocable
licence to:

  a. install and use OpenJSQ on computers you own or control, for
     PERSONAL use, or for use by a NONPROFIT organisation such as an amateur
     radio club, an emergency communications group (for example ARES, RACES
     or similar), a school or a public-service event;

  b. use OpenJSQ to receive and decode signals whether or not you hold an
     amateur radio licence (see section 5 for transmitting); and

  c. give unmodified copies of the official OpenJSQ installer or ZIP to
     others, free of charge, provided that:
       - the copy is complete and unchanged, including this agreement and
         the third-party licence notices in the "licenses" folder;
       - you charge nothing for it beyond the cost of the medium (for example
         a USB stick at a hamfest);
       - you do not bundle it with other software or present it in a way that
         suggests the Author endorses you or your product; and
       - every recipient is bound by this agreement.

3. WHAT YOU MAY NOT DO

Except as section 4 allows or as the law allows despite this restriction,
you may not:

  a. use OpenJSQ for any commercial purpose, including selling it, renting
     it, offering it as part of a paid product or service, or using it in the
     course of a for-profit business, without the Author's written permission;
  b. modify, adapt, translate or create derivative works of OpenJSQ;
  c. reverse engineer, decompile or disassemble OpenJSQ;
  d. remove or alter any copyright, licence or attribution notice; or
  e. use the OpenJSQ name or logo in a way that suggests the Author endorses
     you, your product or your service.

To ask about commercial use, contact the Author at
http://www.openjsq.com/contact/.

4. THIRD-PARTY COMPONENTS

OpenJSQ includes third-party libraries, among them the Qt framework and other
libraries licensed under the GNU Lesser General Public License (LGPL). Those
libraries are licensed to you under their own licences, listed in the
"licenses" folder, and nothing in this agreement limits the rights those
licences give you. In particular you may replace the LGPL libraries supplied
with OpenJSQ with your own versions, and you may reverse engineer OpenJSQ
only as far as necessary to debug such replacements. You may request the
source code of those libraries at http://www.openjsq.com/contact/.

The OpenJSQ protocol specifications published at openjsq.com are made
available under their own terms, which allow you to implement them. This
agreement covers the OpenJSQ software, not those specifications.

5. RADIO REGULATIONS: YOUR RESPONSIBILITY

  a. Transmitting with OpenJSQ requires a radio licence that permits it where
     you operate (in the United States, an FCC amateur radio licence under
     47 CFR Part 97). You must not transmit with OpenJSQ unless you hold such
     a licence.

  b. You, as the station licensee and control operator, are solely
     responsible for every transmission your station makes, including those
     OpenJSQ makes automatically on your behalf: automatic answers, relaying
     or carrying messages for other stations, repeating messages, mail
     custody and delivery, acknowledgements and station identification.

  c. Features such as the automatic airtime limits, the relay forwarding
     allowance, the HF automatic-control sub-band rules, Net mode and Stop TX
     are software safeguards provided for convenience. They are not a
     guarantee that your station complies with any law or regulation, and you
     must not rely on them for compliance. Settings such as "Unlimited (I'm
     responsible)" or "No restriction" place full responsibility on you.

  d. You are responsible for configuring OpenJSQ, your radio and your
     interface equipment correctly, and for operating within your licence
     privileges, band plans, power limits and local rules.

6. NOT FOR LIFE-SAFETY USE

OpenJSQ is experimental amateur radio software. Messages may be delayed,
corrupted, lost or delivered to the wrong station, and automatic features may
not behave as expected. DO NOT rely on OpenJSQ as your only means of
communication in an emergency or in any situation where a failure could lead
to death, personal injury, or property or environmental damage.

7. PRIVACY

OpenJSQ contains no telemetry or advertising. OpenJSQ contacts
www.openjsq.com once when it starts (at most once a day) to learn whether a
newer version exists. That request reveals your IP address and the OpenJSQ
version, as any web request does. It sends no callsign, message or other
data. The check can be turned off in Settings; if it is off, OpenJSQ makes no
such connection. Apart from that check, OpenJSQ communicates only over the
radio, TNC or network connections you configure. Diagnostic bundles are
created only when you choose to create one; they contain recordings and logs
of your station's radio activity and settings, and it is your decision
whether and to whom you send them. Remember that amateur radio transmissions
are public and may be received and recorded by anyone.

8. BETA AND PRE-RELEASE BUILDS

The Author may provide beta or other pre-release builds of OpenJSQ. These are
covered by this agreement, and in addition:

  a. a beta build may require a licence file issued to your callsign, may
     stop working on a date built into it, and may contain more defects than
     a public release;
  b. a licence file is personal to the callsign it names; you must not share,
     publish or transfer it, and the Author may decline to issue or renew one;
  c. section 2c (giving copies to others) does not apply to beta builds or
     licence files: do not redistribute them; and
  d. the Author may ask you for feedback or diagnostic bundles, but you are
     never required to provide them.

9. UPDATES

The Author may, but is not required to, provide updates. An update may
change or remove features. This agreement applies to any update unless the
update comes with a different agreement, in which case that agreement
applies.

10. NO WARRANTY

OPENJSQ IS PROVIDED "AS IS" AND "AS AVAILABLE", WITH ALL FAULTS AND WITHOUT
WARRANTY OF ANY KIND. TO THE FULLEST EXTENT PERMITTED BY LAW, THE AUTHOR
DISCLAIMS ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING ANY IMPLIED
WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE AND
NON-INFRINGEMENT, AND ANY WARRANTY THAT OPENJSQ WILL BE ERROR-FREE,
UNINTERRUPTED, SECURE, OR COMPATIBLE WITH ANY RADIO, INTERFACE OR OTHER
SOFTWARE.

11. LIMITATION OF LIABILITY

TO THE FULLEST EXTENT PERMITTED BY LAW, THE AUTHOR SHALL NOT BE LIABLE FOR
ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY OR PUNITIVE
DAMAGES, OR FOR ANY LOSS OF DATA, MESSAGES, PROFITS OR GOODWILL, DAMAGE TO
RADIO OR COMPUTER EQUIPMENT, INTERFERENCE, FINES, PENALTIES OR REGULATORY
ACTION, ARISING OUT OF OR RELATED TO THIS AGREEMENT OR YOUR USE OF OR
INABILITY TO USE OPENJSQ, HOWEVER CAUSED AND UNDER ANY THEORY OF LIABILITY,
EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. THE AUTHOR'S TOTAL
LIABILITY FOR ALL CLAIMS SHALL NOT EXCEED THE AMOUNT YOU PAID FOR OPENJSQ,
WHICH IS ZERO, OR TEN U.S. DOLLARS (US$10), WHICHEVER IS GREATER.

Some jurisdictions do not allow certain warranties to be excluded or
liability to be limited, so some of the above may not apply to you.

12. INDEMNITY

You agree to defend and hold the Author harmless from any claim, fine or
penalty arising from transmissions made by your station, from your breach of
this agreement, or from your violation of any law or regulation.

13. TERMINATION

This licence ends automatically if you breach this agreement. You may end it
at any time by uninstalling OpenJSQ and deleting all copies. When it ends,
you must stop using OpenJSQ and delete all copies. Sections 4, 5, 6 and 10
through 16 survive termination.

14. EXPORT

You must comply with all export and sanctions laws that apply to your use or
transfer of OpenJSQ.

15. GOVERNING LAW

This agreement is governed by the laws of the State of Alabama, United
States, without regard to its conflict-of-laws rules. Any dispute shall be
brought in the state or federal courts located in Alabama, and you consent to
their jurisdiction, unless the law of your country requires otherwise.

16. GENERAL

This agreement, together with the third-party licences in the "licenses"
folder, is the entire agreement between you and the Author about OpenJSQ. If
any part of it is held unenforceable, the rest remains in effect. The
Author's failure to enforce any provision is not a waiver of it. You may not
assign this agreement; the Author may. The Author may publish a revised
version of this agreement; it applies to versions of OpenJSQ released with
it.
