Copyright (c) 2026 the individual software developer publishing

IMPORTANT: READ THIS AGREEMENT BEFORE USING OR REDISTRIBUTING THE SOFTWARE.
BY INSTALLING, COPYING, RUNNING, OR REDISTRIBUTING THE SOFTWARE, YOU ACCEPT
THIS AGREEMENT. IF YOU DO NOT ACCEPT IT, DO NOT USE OR REDISTRIBUTE THE
SOFTWARE.

--------------------------------------------------------------------------------
1. DEFINITIONS
--------------------------------------------------------------------------------

"Software" means the PolymathPlus Local Engine Workbench executable in
object-code form, its accompanying documentation, and the files supplied in
the official PolymathPlus download package. Third-party components are
excluded where their own license terms apply.

"Licensor" means the individual copyright owner who publishes the Software
under the pseudonym "PolymathPlus," together with that owner's heirs,
successors, and assigns.

"PolymathPlus" is a pseudonym and product name. It is not represented as a
separate corporation, partnership, association, or other legal entity.

"You" means the individual or legal entity accepting this Agreement. If you
accept it on behalf of an organization, you represent that you have authority
to bind that organization.

"Authorized Users" means your employees, contractors, faculty members,
researchers, or students who use the Software under your administrative
responsibility.

"Official Package" means an unmodified release archive obtained from the
official PolymathPlus website or an authorized free mirror and containing the
original executable, EULA.txt, and supplied documentation.

--------------------------------------------------------------------------------
2. FREE LICENSE GRANT
--------------------------------------------------------------------------------

Subject to this Agreement, the Licensor grants You a royalty-free,
non-exclusive, worldwide license to:

a. install and run the unmodified Software on devices owned or controlled
   by You;

b. use the Software for personal, educational, academic, research,
   evaluation, engineering, professional, nonprofit, and internal business
   purposes;

c. operate the Software as a local or internal network service for Authorized
   Users within your own organization or educational institution;

d. make reasonable backup copies and internal deployment copies; and

e. create and use your own external configuration files, operating-system
   service definitions, deployment scripts, startup scripts, monitoring
   configurations, and administrative procedures, provided they do not
   modify the Software itself.

This license is provided without a license fee. It continues unless terminated
under Section 12.

The Software is licensed, not sold. No source-code license, source-code access,
or ownership interest is granted.

--------------------------------------------------------------------------------
3. COMMERCIAL USE OF WORK AND RESULTS
--------------------------------------------------------------------------------

You may use the Software while performing paid employment, engineering,
consulting, research, or other professional work.

You may charge for your own professional services and for reports, designs,
models, calculations, recommendations, and other work products created using
the Software.

The Licensor claims no ownership of your original input data, models, or
calculation results merely because they were processed using the Software.

These permissions do not allow You to sell the Software itself, charge for
access to it, or offer it as a paid hosted or managed software service.

--------------------------------------------------------------------------------
4. FREE REDISTRIBUTION
--------------------------------------------------------------------------------

You may redistribute the complete Official Package only when all the following
conditions are satisfied:

a. redistribution is entirely free of charge;

b. the Official Package and all included files remain complete and unmodified;

c. this EULA, all copyright notices, and all third-party notices remain
   included and readable;

d. the Software is clearly identified as originating from PolymathPlus;

e. the official website, https://www.polymathplus.org/, is identified as the
   original source; and

f. You do not claim authorship, ownership, sponsorship, endorsement, official
   distributor status, or support authorization from PolymathPlus.

Attribution does not create permission to sell the Software or charge for
access to it.

Recipients receive their license directly from the Licensor under this
Agreement. You are not authorized to sublicense the Software.

--------------------------------------------------------------------------------
5. PROHIBITED COMMERCIALIZATION
--------------------------------------------------------------------------------

Without separate written permission from the Licensor, You must not:

a. sell, rent, lease, sublicense, license for a fee, or otherwise charge for
   the Software or any copy of it;

b. include the Software as a paid component of another product, package,
   appliance, installer, subscription, or service;

c. charge a download fee, activation fee, access fee, hosting fee, maintenance
   fee, or support fee whose material subject is the Software;

d. provide paid hosted, cloud, Software-as-a-Service, bureau, managed-service,
   or remote-access use of the Software to third parties; or

e. use free access to the Software primarily to promote or enable the sale of
   unauthorized copies, access, subscriptions, or substantially equivalent
   commercial offerings.

Internal use by a business or educational institution, and charging for
independent professional work products as permitted by Section 3, are not
prohibited commercialization.

--------------------------------------------------------------------------------
6. NO MODIFICATION OR REVERSE ENGINEERING
--------------------------------------------------------------------------------

Except to the limited extent that applicable law expressly makes a restriction
unenforceable, You must not:

a. modify, patch, translate, adapt, alter, or create derivative works from the
   Software;

b. reverse engineer, decompile, disassemble, decode, decrypt, or otherwise
   attempt to discover source code, algorithms, internal structure, or
   nonpublic interfaces;

c. bypass or disable technical restrictions, access controls, security
   features, or usage limitations;

d. remove, hide, replace, or alter copyright, license, attribution, branding,
   or other proprietary notices; or

e. represent a modified, repackaged, or independently compiled program as an
   official PolymathPlus release.

Normal operating-system configuration, environment-variable configuration,
service registration, firewall configuration, log routing, monitoring, backup,
and external automation do not constitute modification when the supplied
executable itself remains unchanged.

--------------------------------------------------------------------------------
7. INTERNAL DEPLOYMENT
--------------------------------------------------------------------------------

Organizations may create internal deployment mechanisms for Authorized Users,
including fleet-installation scripts, software-distribution packages, service
configurations, and monitoring templates.

Such mechanisms must:

a. preserve the supplied executable without modification;

b. include or make this EULA reasonably available to Authorized Users;

c. remain under the organization's own administrative responsibility; and

d. not be marketed or supplied to third parties as an official PolymathPlus
   installer, managed service, or supported deployment product.

PolymathPlus does not test, certify, warrant, or support user-created deployment
or service-installation mechanisms.

--------------------------------------------------------------------------------
8. OWNERSHIP AND BRANDING
--------------------------------------------------------------------------------

The Licensor retains all rights, title, and interest in and to the Software,
including all copyrights and other intellectual-property rights not expressly
granted by this Agreement.

"PolymathPlus," associated product names, logos, visual identifiers, and
branding remain the property of their respective owner. This Agreement grants
only the limited right to reproduce the name as required for truthful
attribution.

No permission is granted to suggest endorsement, certification, partnership,
affiliation, or sponsorship by PolymathPlus.

--------------------------------------------------------------------------------
9. THIRD-PARTY COMPONENTS
--------------------------------------------------------------------------------

The Software may include third-party components distributed under separate
license terms. Those separate terms govern the corresponding third-party
components.

Nothing in this Agreement removes or restricts rights granted directly by a
third-party license. Third-party copyright and license notices must remain
intact.

--------------------------------------------------------------------------------
10. LOCAL OPERATION, DATA, AND SECURITY
--------------------------------------------------------------------------------

The current PolymathPlus Local Engine is designed to operate locally without
requiring a PolymathPlus user account or cloud-hosted calculation service.

You are responsible for securing the computer and network on which the
Software runs, controlling access to the service, protecting input and output
data, maintaining backups, selecting appropriate service accounts, configuring
logs, and complying with applicable privacy and data-protection requirements.

You must independently validate important calculations and results before
relying on them for engineering, safety, financial, operational, academic, or
other decisions.

--------------------------------------------------------------------------------
11. UPDATES, SUPPORT, AND DISCONTINUATION
--------------------------------------------------------------------------------

The Licensor has no obligation to provide maintenance, support, corrections,
updates, compatibility changes, security fixes, documentation, downloads, or
continued website availability.

The Licensor may release future versions under different terms and may
discontinue the Software, website, downloads, or support at any time.

Discontinuation of the PolymathPlus name, website, project, or support activity
does not by itself terminate licenses validly granted for existing versions.
The Licensor's rights and obligations may pass to heirs, successors, or
assigns.

--------------------------------------------------------------------------------
12. TERMINATION
--------------------------------------------------------------------------------

Your license terminates automatically if You materially violate this Agreement.

Upon termination, You must stop using and redistributing the Software and
delete copies under your control, except for copies that applicable law
requires You to retain.

Sections concerning ownership, restrictions, disclaimers, liability,
termination, applicable law, and general terms survive termination to the
extent necessary to give them effect.

--------------------------------------------------------------------------------
13. 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.

THE LICENSOR DISCLAIMS ALL EXPRESS, IMPLIED, AND STATUTORY WARRANTIES,
INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE,
TITLE, NONINFRINGEMENT, ACCURACY, RELIABILITY, AVAILABILITY, SECURITY, AND
ERROR-FREE OPERATION.

THE LICENSOR DOES NOT WARRANT THAT THE SOFTWARE OR ITS RESULTS WILL MEET YOUR
REQUIREMENTS, BE COMPLETE OR CORRECT, OPERATE WITHOUT INTERRUPTION, OR BE
SUITABLE FOR ANY SAFETY-CRITICAL, REGULATED, OR PROFESSIONAL PURPOSE.

--------------------------------------------------------------------------------
14. LIMITATION OF LIABILITY
--------------------------------------------------------------------------------

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE LICENSOR, DEVELOPERS,
CONTRIBUTORS, DISTRIBUTORS, AND PARTNERS SHALL NOT BE LIABLE FOR ANY DIRECT,
INDIRECT, INCIDENTAL, SPECIAL, EXEMPLARY, PUNITIVE, OR CONSEQUENTIAL DAMAGES,
OR FOR LOSS OF DATA, PROFITS, SAVINGS, REVENUE, BUSINESS, OPPORTUNITY,
REPUTATION, OR BUSINESS CONTINUITY, ARISING FROM OR RELATED TO THE SOFTWARE,
ITS OUTPUTS, OR THE INABILITY TO USE IT.

TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE AGGREGATE LIABILITY ARISING FROM
OR RELATED TO THE SOFTWARE SHALL NOT EXCEED THE AMOUNT YOU PAID SPECIFICALLY
FOR THE SOFTWARE.

Because the Software is provided without a license fee, that amount will
normally be zero.

Nothing in this Agreement excludes liability that cannot lawfully be excluded
or limited.

--------------------------------------------------------------------------------
15. COMPLIANCE WITH LAW
--------------------------------------------------------------------------------

You are responsible for using the Software in compliance with applicable laws,
regulations, professional obligations, institutional rules, export controls,
and safety requirements.

Nothing in this Agreement restricts rights that applicable law does not permit
the parties to exclude by contract.

--------------------------------------------------------------------------------
16. APPLICABLE LAW AND DISPUTES
--------------------------------------------------------------------------------

This Agreement is subject to applicable law. Any dispute arising from or
related to this Agreement or the Software shall be resolved by a court of
competent jurisdiction.

Nothing in this Agreement excludes or limits rights, remedies, or protections
that cannot lawfully be excluded or limited.

--------------------------------------------------------------------------------
17. GENERAL TERMS
--------------------------------------------------------------------------------

This Agreement is the complete agreement concerning copies of the Software
first distributed with this EULA. It does not alter licenses validly granted
for copies distributed under earlier license terms.

If any provision is found unenforceable, it shall be limited or removed only
to the minimum extent necessary, and the remaining provisions shall continue
in effect.

Failure to enforce a provision is not a waiver of that provision.

Headings are provided for convenience and do not affect interpretation.

The Licensor may assign copyright and this Agreement to a successor. You may
not assign or transfer your rights except through the permitted free
redistribution described in Section 4.
