RaiSim and Rayrai WebAssembly License Agreement

Copyright (c) 2026 RaiSim Tech Inc. All rights reserved.

1. Scope

This agreement governs the publicly distributed WebAssembly edition of RaiSim
and Rayrai, including its browser applications, its software development kit of
prebuilt libraries, headers, build files and page runtime (the "SDK"), and
supporting files (the "Software"). RaiSim Tech Inc. grants you a non-exclusive,
non-transferable license to download, cache, and run copies of the Software for
the purposes expressly permitted below. This agreement does not grant rights to
the native edition or implementation source code. A separate written agreement
covering this edition governs the uses it expressly authorizes.

2. Academic research

You may use the Software free of charge, without a weekly time limit, solely
for academic research if you meet the eligibility requirements in Clause 1 of
the RaiSim Academic License Agreement:
https://drive.google.com/file/d/10W_9H8Ur37B6GllR0Qb3JQyj7Fh-AVlx/view

Those eligibility requirements are:
  a. Students: you are a full-time student at a government-recognised
     university, or you are 18 years old or younger.
  b. Teachers: you teach students at a government-recognised university.
  c. Researchers: you are employed by a government-recognised university.

For these requirements, a government-recognised university is an institution
that offers government-recognised doctoral degrees. Academic eligibility does
not authorize commercial activities under this academic research permission.

3. Commercial evaluation

Commercial users may use the Software free of charge solely to evaluate its
suitability, for a maximum of two hours (120 minutes) per individual user per
calendar week, aggregated across all accounts, devices, and browser sessions.
A calendar week starts on Monday at 00:00 UTC and ends at the following Monday
at 00:00 UTC. The allowance concerns elapsed usage time, not simulated time.
Unused time does not carry over and allowances may not be transferred or pooled.

This permission does not authorize production use or providing commercial
services to third parties. Commercial use beyond the evaluation permission,
including production use or evaluation exceeding the weekly allowance, requires
a separate commercial license from RaiSim Tech Inc. Contact:

4. Programs built with the SDK

You may use the SDK to build your own WebAssembly programs ("Programs") within
the permissions of Clauses 2 and 3. A person who meets the academic eligibility
requirements of Clause 2 may also distribute a Program, solely for academic
purposes (academic research or teaching, and not commercial activities), on
these conditions:

  a. Only the Program. You may distribute a Program, including the parts of
     RaiSim and Rayrai compiled into it and the runtime files the SDK places
     beside it. You may not redistribute RaiSim or Rayrai themselves: the SDK,
     its libraries, headers or other files on their own, the browser
     applications of the Software, or RaiSim or Rayrai extracted from a
     Program. You may not distribute a Program whose purpose is to let others
     build or link programs with RaiSim or Rayrai.
  b. Clear notice. Every distribution of a Program must state clearly that it
     is built with RaiSim and Rayrai and is subject to this agreement, and must
     include this agreement and the accompanying third-party notices. A Program
     presented on a web page must show this notice, with a link to this
     agreement, on that page.
  c. No further rights. Recipients and users of a Program receive no rights to
     RaiSim or Rayrai beyond those of this agreement, and you may not grant
     them any; their use of the Program is subject to this agreement.

Nobody else may distribute Programs, and Programs may not be distributed for
any other purpose, without a separate written license from RaiSim Tech Inc.

5. Compliance and reserved rights

You are responsible for complying with these restrictions regardless of whether
usage is technically monitored or limited. The absence of a timer, account
requirement, activation check, or other technical restriction does not expand
the permissions granted by this agreement. These terms apply to commercial
users of every company size.

All rights not expressly granted are reserved. Except as required by applicable
law, permitted in a separate written agreement, or permitted for Programs by
Clause 4, you may not modify, disassemble, reverse-engineer, redistribute, or
sublicense the Software. You must retain this agreement and the accompanying
third-party notices with any copies you are permitted to make. If you do not
comply with this agreement, your permission to use the Software ends and you
must stop using it.

6. Third-party components and user content

Third-party components and assets remain subject to their respective licenses
and notices, including THIRD_PARTY_NOTICES.txt and notices in asset packages.
This agreement does not restrict rights granted by those third-party licenses.
RaiSim Tech Inc. claims no ownership of scenes or other content you create
through the Software by virtue of this agreement.

7. Disclaimer

To the extent permitted by applicable law, the Software is provided "AS IS",
without express or implied warranties, including warranties of merchantability,
fitness for a particular purpose, or non-infringement. RaiSim Tech Inc. is not
liable for direct, indirect, incidental, special, exemplary, or consequential
damages arising from use of the Software, including loss of use, data, or
profits, or business interruption, even if advised of the possibility of such
damages. Nothing in this agreement excludes liability that applicable law does
not permit to be excluded.
