Acceptance

In order to get any license under these terms, you must agree
to them as both strict obligations and conditions to all
your licenses.

Copyright License

The licensor grants you a copyright license for the
software to do everything you might do with the software
that would otherwise infringe the licensor's copyright
in it for any permitted purpose. However, you may
only distribute the software according to Distribution
License and make changes or new works based on the software
according to Changes and New Works License.

Distribution License

The licensor grants you an additional copyright license
to distribute copies of the software. Your license
to distribute covers distributing the software with
changes and new works permitted by Changes and New Works
License.

Changes and New Works License

The licensor grants you an additional copyright license
to make changes and new works based on the software for
any permitted purpose.

Patent License

The licensor grants you a patent license for the software
that covers patent claims the licensor can license, or
becomes able to license, that you would infringe by using
the software.

Noncommercial Purposes

Any noncommercial purpose is a permitted purpose.

Personal Uses

Personal use for research, experiment, and testing for
the benefit of public knowledge, personal study, private
entertainment, hobby projects, amateur pursuits, or
religious observance, without any anticipated commercial
application, is use for a permitted purpose.

Noncommercial Organizations

Use by any charitable organization, educational
institution, public research organization, public safety
or health organization, environmental protection
organization, or government institution is use for a
permitted purpose regardless of the source of funding
or obligations resulting from the funding.

Fair Use

You may have "fair use" rights for the software under the
law. These terms do not limit them.

No Other Rights

These terms do not allow you to sublicense or transfer
any of your licenses to anyone else, or prevent the
licensor from granting licenses to anyone else. These
terms do not imply any other licenses.

Patent Defense

If you make any written claim that the software infringes
or contributes to infringement of any patent, your patent
license for the software granted under these terms ends
immediately. If your company makes such a claim, your
patent license ends immediately for work on behalf of your
company.

Violations

The first time you are notified in writing that you have
violated any of these terms, or done anything with the
software not covered by your licenses, your licenses can
nonetheless continue if you come into full compliance with
these terms, and take practical steps to correct past
violations, within 32 days of receiving notice. Otherwise,
all your licenses end immediately.

No Liability

***As far as the law allows, the software comes as is,
without any warranty or condition, and the licensor
will not be liable to you for any damages arising out of
these terms or the use or nature of the software, under
any kind of legal claim.***

Definitions

The "licensor" is the individual or entity offering these
terms, and the "software" is the software the licensor
makes available under these terms.

"You" refers to the individual or entity agreeing to these
terms.

"Your company" is any legal entity, sole proprietorship,
or other kind of organization that you work for, plus all
organizations that have control over, are under the control
of, or are under common control with that organization.
"Control" means ownership of substantially all the assets
of an entity, or the power to direct its management and
policies by vote, contract, or otherwise. Control can be
direct or indirect.

"Your licenses" are all the licenses granted to you for the
software under these terms.

"Use" means anything you do with the software requiring
one of your licenses.

Layer 3: Rho desktop app + cloud.rho.md

Rho desktop application + cloud.rho.md SaaS 平台采用闭源——无公开 license 文本。

Desktop app personal use 受其内置 EULA 约束（首次启动时显示 + 同意）
Cloud Service 受 Terms of Service 约束
Commercial / Team / Enterprise 受签约时具体合同约束

EULA / ToS 文本会在 v1.0 binary release / cloud MVP 上线时发布并链接到这里。

商业 license 合同模板

Rho commercial license 用 scos-lab 标准 SaaS / library license 合同模板——首次询价时 [email protected] 会发 PDF 模板供你 review / 谈判修订。

合同核心覆盖：

使用范围（per-developer / per-project / OEM / source-code）
License 期限（1 / 2 / 3 年 / 永久）
付款条款（net-30 / 60 / 一次性）
IP 归属（你的 derivative work IP 你拥有；spec 和 library 的 IP 仍归 scos-lab）
Confidentiality（商业 build / source-code 受 NDA）
免责 + 责任上限（标准 SaaS 行业惯例）
Termination 条款
Governing law（默认 mainland China + USA 双 jurisdiction，可谈）

第三方依赖 license

@rho/md 库的运行依赖（你引入时一并安装）：

依赖	License
`unified`	MIT
`remark-parse`	MIT
`remark-gfm`	MIT
`remark-rehype`	MIT
`rehype-stringify`	MIT
`unist-util-visit`	MIT
`highlight.js` (optional)	BSD-3-Clause
`vega-embed` (optional)	BSD-3-Clause

这些依赖各自 license 跟 @rho/md 独立——你的项目同时受所有 license 约束。MIT / BSD 的依赖跟 PolyForm NC 不冲突——你商业用 @rho/md 时，依赖正常使用即可。

历史版本

Layer	License 版本	适用日期
Spec	CC BY 4.0	2026-01-15 起
Library	PolyForm NC 1.0.0	2026-05-13 起（前期 v0.0.x 无明确 license——视为 PolyForm NC 1.0 适用）
