﻿Twinwright Studio — End-User Licence Agreement

Version 1, 11 October 2026. Between you and Twinwright (twinwright.com, hello@twinwright.com) ("Twinwright").

By installing or using Twinwright Studio ("Studio") you accept this agreement. If you do not accept it, do not install or use Studio.

1. Licence. Twinwright grants you a non-exclusive, non-transferable licence to install and use Studio in one of these editions:
   - Learning edition — free of charge, on any number of computers, for learning, teaching and personal projects that earn no money;
   - Maker — for one person, including selling what that person makes;
   - Pro — per seat, for any commercial use by you or your organisation, including work for clients;
   - Classroom — for teaching at the school or training centre named in the order, on the seats bought, at school and at the students' homes;
   - MC-1 owner licence — Pro for one seat, for use with the MC-1 whose serial number it names; it passes to the next owner with the machine.

   A paid seat may be used by one person at a time, on up to three computers; a computer that several people share counts once. A free trial of a paid edition lasts 30 days, once per person.
2. Subscriptions and licences you own. A subscription runs by the month or by the year and renews until you cancel it; cancelling takes effect at the end of the period paid. A licence you own lets you use, for good, every version released within 12 months of its purchase or of a paid renewal of updates. Until online sales open, Twinwright issues paid licences on order (sales@twinwright.com), under the terms of that order. Online sales will go through a reseller acting as merchant of record, whose terms of sale and refund policy, and your statutory rights, will apply to the payment; a new version of this agreement will name it.
3. Licence file. A paid licence is a signed file that Studio checks on your computer. Studio renews it when you are online; a computer without internet can be activated from a file. When a subscription ends, Studio returns to the free edition: your files remain yours and usable, and only the paid functions stop.
4. What you may not do. You may not sell, rent, sublicense or redistribute Studio or parts of it, publish it for download, share a licence file beyond the seats bought, work around the licence check, or remove Studio's notices, without Twinwright's written permission. You may not reverse-engineer, decompile or disassemble Studio, except to the extent the law of your country allows it despite this clause.
5. Ownership. Studio is licensed, not sold. Twinwright and its licensors keep all rights in Studio, including its simulation, its CAM and the controller firmware it contains. Third-party components come with their own licences, listed in the notices file installed with Studio; nothing in this agreement limits your rights under those licences.
6. Your work. Your programs, drawings, settings, recordings and audit logs are yours. Studio keeps them on your computer and sends nothing about you or your work to Twinwright; it does not check for new versions by itself. Starting a free trial, or activating or renewing a paid licence, sends only the activation code (when activating), the licence's identifier (on a renewal), the edition (for a trial), a one-way hash of your computer's identifier (never the identifier itself) and Studio's version — nothing about you or your work; Twinwright's privacy notice says what is kept and for how long.
7. AI features. The AI features send nothing until you set them up and use them. If you connect the AI assistant to a third-party AI service, Studio sends that service, from your computer with your account and key, your messages with the conversation so far, the window's program, setup and check results while the box to attach them is ticked (it is by default), and the results of the tools the assistant uses; that service handles them under its terms, and you are responsible for that use. With a local model they stay on your computer. Answers and programs from AI assistants can be wrong, even after the twin has checked them.
8. Simulation is not a guarantee. Studio models a machine with nominal parameters until that machine is calibrated. Its results help you judge a program; they do not guarantee that the program is safe or correct on any real machine. You decide what runs on a machine, and you are responsible for operating it safely.
9. No warranty. To the extent the law allows, Studio is provided "as is", without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose and non-infringement.
10. Limitation of liability. To the extent the law allows, Twinwright is not liable for indirect, incidental, special or consequential damages, or for lost profits, data, tools, workpieces or machine time, arising from the use of Studio. Twinwright's total liability under this agreement is limited to what you paid for Studio in the 12 months before the claim, or USD 100 if that is more. Nothing in this agreement limits liability that cannot be limited by law.
11. Updates and end. Twinwright may publish new versions; this agreement covers them unless a new version comes with a new agreement. Your licence ends if you break this agreement; then you must stop using Studio and delete it.
12. Export. You will comply with the export-control and sanctions laws that apply to you and to Studio.
13. Law. This agreement is governed by the laws of the United Arab Emirates; the courts of the United Arab Emirates have jurisdiction, unless the consumer law of your country gives you other rights.

同匠 Studio 最终用户许可协议

第 1 版，2026 年 10 月 11 日。你与同匠 Twinwright（twinwright.com，hello@twinwright.com；下称“同匠”）之间的协议。

安装或使用同匠 Studio（“Studio”）即表示你接受本协议。不接受的，请不要安装或使用。

1. 许可。同匠授予你非独占、不可转让的许可，按以下版本之一安装和使用 Studio：
   - 学习版——免费，可装在任意多台电脑上，用于学习、教学和不挣钱的个人项目；
   - 创客版——供一个人使用，包括出售这个人自己做的东西；
   - 专业版——按席位，供你或你所在的单位用于任何商业用途，包括为客户加工；
   - 课堂版——供订单上写明的学校或培训机构教学使用，席位数按购买的数量，可在学校和学生家里使用；
   - MC-1 机主授权——一个席位的专业版，配合授权上写明序列号的那台 MC-1 使用；机器转让时随机器转给新机主。

   每个付费席位同一时间由一个人使用，最多用在三台电脑上；几个人共用的一台电脑只算一台。付费版本可免费试用 30 天，每人一次。
2. 订阅和买断。订阅按月或按年，在你取消之前自动续期；取消在已付费的期限结束时生效。买断的授权可以永久使用购买（或付费续更新）后 12 个月内发布的所有版本。开通在线购买之前，付费授权由同匠按订单签发（sales@twinwright.com），适用该订单的条款。开通在线购买后，经作为代收方（merchant of record）的代理销售商销售，付款适用其销售条款和退款政策，你的法定权利不受影响；届时新版本的协议会写明是哪一家。
3. 授权文件。付费授权是一个经过签名的文件，由 Studio 在你的电脑上核验。联网时 Studio 自动续期；没有网络的电脑可以用文件激活。订阅结束后 Studio 回到学习版：你的文件仍然归你、照常可用，只是付费功能停止。
4. 不可以做的事。未经同匠书面许可，不得出售、出租、转授权或再分发 Studio 或其中的部分，不得把它发布到网上供人下载，不得在购买的席位之外共享授权文件，不得绕过授权核验，不得去掉其中的声明。不得对 Studio 进行反向工程、反编译或反汇编，你所在国家或地区的法律在本条款之外另有允许的除外。
5. 权利归属。Studio 是授权使用，不是出售。同匠及其许可方保留 Studio 的全部权利，包括其中的仿真、CAM 和控制器固件。第三方组件按各自的许可随附，清单见随 Studio 安装的声明文件；本协议不限制你依照这些许可享有的权利。
6. 你的成果。你的程序、图纸、设置、录制和审计日志归你所有。Studio 把它们保存在你的电脑上，不向同匠发送任何关于你或你的工作的数据，也不会自己检查新版本。开始免费试用、激活或续期付费授权时，只发送激活码（激活时）、授权的 ID（续期时）、所试用的版本（试用时）、你电脑标识的单向散列值（从不发送标识本身）和 Studio 的版本——都不是关于你或你工作的内容；保存什么、保存多久见同匠的隐私说明。
7. AI 功能。AI 功能在你设置并使用之前什么都不发。你把 AI 助手接到第三方 AI 服务时，Studio 从你的电脑、用你的账户和密钥，把你的消息连同到这时为止的对话、勾着附上选项时（默认勾着）窗口里的程序、装夹和检查结果，以及助手调用工具得到的结果发给该服务，按其条款处理，相关使用由你负责。用本机模型时，这些都留在你的电脑上。AI 助手给出的回答和程序可能是错的，即使孪生已经检查过。
8. 仿真不是保证。在机床标定之前，Studio 用名义参数为机床建模。它的结果帮助你判断一个程序，不保证这个程序在任何真实机床上安全或正确。什么程序上机由你决定，安全操作机床由你负责。
9. 不提供担保。在法律允许的范围内，Studio 按“现状”提供，不作任何明示或默示的担保，包括适销性、特定用途适用性和不侵权。
10. 责任限制。在法律允许的范围内，同匠不对因使用 Studio 引起的间接、附带、特殊或后果性损失负责，也不对利润、数据、刀具、工件或机时的损失负责。同匠在本协议下的全部责任，以索赔前 12 个月内你为 Studio 支付的金额为限；该金额低于 100 美元的，以 100 美元为限。法律规定不能限制的责任不受本条限制。
11. 更新与终止。同匠可以发布新版本；新版本没有附带新协议的，适用本协议。你违反本协议时许可自动终止，你须停止使用并删除 Studio。
12. 出口管制。你应遵守适用于你和 Studio 的出口管制与制裁法律。
13. 适用法律。本协议适用阿拉伯联合酋长国法律，由阿拉伯联合酋长国的法院管辖；你所在国家或地区的消费者保护法律另有规定的除外。
14. 联系方式。同匠 Twinwright，hello@twinwright.com。
