1. 接受条款
下载、安装或使用 Mac 上的 Klee 应用（下称「应用」）、注册账号或购买额度，即表示你同意受本条款约束。应用由 Signer Labs（下称「我们」）运营。如果你不同意，请不要使用应用。我们如何处理信息，见隐私政策。
2. Klee 是什么
Klee 是 Mac 上的助手。你用平常的话说要做什么，它就在你自己的电脑上去做：读写文件、运行命令、查资料，以及制作 Word、Excel、PPT、PDF 等文档。具体的工作由 AI 模型完成，即 Anthropic 的 Claude；你的请求通过我们的服务发给它。
使用应用需要 macOS 15 或更高版本、Apple 芯片的 Mac、互联网连接和一个账号。
Klee 目前是内测版。功能可能调整或取消，有些地方可能不如预期。
3. 谁可以使用
你必须年满 18 岁；如果你所在地的成年年龄更高，以当地为准。
服务在部分国家或地区可能无法使用。
4. 账号
- 用邮箱登录：我们把一次性验证码发到你的邮箱。谁能打开这个邮箱，谁就能登录你的账号，所以请保管好邮箱。
- 账号只供你本人使用，不得出借、出售或转让。
- 你对自己账号下发生的一切使用负责。发现账号被别人使用，请尽快告诉我们。
5. 额度与付款
5.1 预付额度，不是订阅
Klee 按预付额度收费。你先购买额度包（目前有 10 美元、30 美元、100 美元三档，购买前应用里会显示），付多少到账多少。没有周期性扣款，我们不会自动向你收费。余额用完后，Klee 会停止处理新的请求，直到你再次购买。
5.2 试用额度
新账号会得到 1 美元的试用额度。试用额度每人一份，不能兑现，不能退款。通过重复注册等方式套取的试用额度，我们可以收回。我们可以随时调整或停止向新账号赠送试用额度。
5.3 怎么扣
每次向模型发出的请求，按所用的模型和处理的 token 数量计费，从余额里扣除。不同模型价格不同；对话越长、读的文件越大，用得越多。余额和用量可以在应用的设置里查看。
计费标准可能调整，调整只对之后的使用生效。
正在进行的请求可能让余额略低于零，差额会在你下次购买时补上。
5.4 付款
付款由 Stripe 处理。价格以美元计。如果有适用的税费，会在付款页面上显示。你的银行或发卡机构可能另收货币转换等费用。
5.5 额度的性质
额度只能用于 Klee。它不是货币，不是存款，不计利息，不能兑换成现金，也不能在账号之间转让或转卖。
5.6 有效期
购买的额度目前不设有效期。如果以后设定有效期，只适用于公布之后购买的额度。
5.7 退款
已经用掉的额度不能退款。如果扣错了款、重复扣款，或者付了钱额度没有到账，请写信告诉我们，我们会更正。
对尚未使用的已购额度有其他退款要求，请写信到 wei@signerlabs.com，我们会逐个处理。本条款不限制你依所在地法律享有的退款或撤销购买的权利。
对某笔扣款有疑问，请先联系我们。付款发生争议期间，我们可以暂停相关账号。
6. Klee 在你的电脑上做什么
Klee 按你的指示在你的电脑上做事。视任务而定，它可能新建、修改、移动和删除文件，运行命令，下载它完成任务所需的组件，以及访问互联网。它拥有的权限，就是你的 macOS 用户账号和系统授予它的权限。
- 自动模式（默认）：它自己往下做，只在它认为撤销不了的操作之前先问你。
- 手动模式：每次改文件、运行命令之前都先问你。
Klee 对「什么安全、什么可以撤销」的判断可能出错。交给它什么任务、选哪种模式和哪个工作文件夹、检查它做了什么，都由你负责。重要的东西请留好备份。不要让它处理你无权使用或修改的系统和数据。
7. AI 生成的内容
Klee 的回答和它制作的文件由 AI 生成，可能不准确、不完整或有错误。依赖之前请自行核对。这些内容不构成法律、医疗、财务等方面的专业意见。如何使用它们，由你负责。
8. 你的内容
你的文件、你输入的话以及 Klee 为你生成的内容，在你和我们之间归你所有。我们不保存这些内容；为了完成任务，它们会按隐私政策所述发给模型处理。你只授予我们为提供服务而传输这些内容所必需的许可。
请确认你有权把交给 Klee 的内容交给第三方的服务处理。不要让它处理你依法或依约定不得对外提供的内容。
9. 使用规范
你同意不做下列事情：
- 把应用用于任何违法目的，或违反适用的法律；
- 违反 Anthropic 的使用政策（你的请求由它的模型处理）；
- 不经应用而直接调用我们的服务，把它当作通用的模型接口，或转卖、出借使用权；
- 绕过计费、额度、频率限制或其他技术限制，或为套取试用额度注册多个账号；
- 干扰、探测或攻击我们的服务；
- 在法律允许的范围之外，对应用进行反向工程、反编译或反汇编；
- 用 Klee 侵入或破坏他人的系统和数据。
为了保护服务，我们可以限制请求的频率。
10. 第三方的服务和软件
模型由 Anthropic 提供，付款由 Stripe 处理，它们各自的条款适用于它们负责的部分。Klee 是 Signer Labs 的独立产品，与 Anthropic 没有隶属关系，也未获其背书。Claude 是 Anthropic 的商标。
你自己接入的工具、添加的技能，以及 Klee 为你访问的网站，由各自的提供方负责，使用它们的风险由你承担。应用包含的开源软件按各自的许可证授权。
11. 许可与知识产权
在你遵守本条款的前提下，我们授予你一项个人的、非独占的、不可转让的、可撤销的许可，在你拥有或控制的 Mac 上安装和使用应用。应用（包括设计、代码、图形和品牌）归 Signer Labs 所有，受知识产权法律保护。本条款不授予你使用我们的商标或品牌的权利。
12. 服务的变更与中断
我们可能增加、修改或取消功能，可用的模型也可能随提供方而变化。服务可能因维护、故障或我们无法控制的原因而中断，我们不保证它始终可用。
如果我们决定停止运营 Klee，会提前在本网站和通过邮件通知，并说明届时未使用的已购额度如何处理。
13. 暂停与终止
你可以随时停止使用应用。删除应用不会删除它存在你 Mac 上的数据，那些要你自己删除；要删除账号，请写信给我们。
如果你违反本条款、涉嫌欺诈，或法律要求我们这样做，我们可以暂停或终止你对服务的使用。此时未使用的已购额度按第 5.7 节处理。
14. 不作保证
应用按「现状」和「现有」的状态提供，不附带任何明示或默示的保证，包括但不限于适销性、适合特定用途和不侵权的保证。我们不保证应用不会中断、没有错误，不保证它的输出准确，也不保证不会发生数据丢失。
15. 责任限制
在法律允许的最大范围内，Signer Labs 不对任何间接的、附带的、特殊的、后果性的或惩罚性的损害负责，也不对因使用应用而产生或与之相关的任何数据丢失负责。对于因本条款或应用引起的任何索赔，我们的全部责任不超过你在索赔发生前十二个月内向我们支付的金额。
有些地方的法律不允许上述某些排除或限制；在那些地方，它们只在法律允许的范围内适用。
16. 适用法律
本条款适用美国特拉华州法律，不适用其法律冲突规则。如果你是消费者，你所在国家法律中的强制性保护仍然适用于你。
17. 条款的变更
我们可能不时更新本条款。有重大变更时，我们会把新版本发布在本页并修改「最后更新」的日期。变更生效后继续使用应用，即表示你接受修改后的条款。
18. 语言
本条款有中文和英文两个版本。两个版本不一致时，以英文版为准。
19. 联系我们
对本条款有疑问，请联系：
1. Acceptance of terms
By downloading, installing or using the Klee application for Mac (the “App”), creating an account, or buying credit, you agree to be bound by these Terms of Use. The App is operated by Signer Labs (“we,” “us,” or “our”). If you do not agree to these terms, please do not use the App. Our Privacy Policy explains how information is handled.
2. What Klee is
Klee is an assistant for the Mac. You say what you want in plain words, and Klee does it on your own computer: reading and writing files, running commands, looking things up, and making documents such as Word, Excel, PowerPoint and PDF files. The work is done by AI models, Anthropic's Claude, which your requests are sent to through our service.
The App requires macOS 15 or later, a Mac with Apple silicon, an internet connection, and an account.
Klee is currently a beta. Features may change or be removed, and some things may not work as expected.
3. Who can use Klee
You must be at least 18 years old, or the age of majority where you live if that is higher.
The service may not be available in some countries or regions.
4. Your account
- You sign in with your email address: we send a one-time code to it. Anyone who can open that inbox can sign in to your account, so keep it secure.
- Your account is for you alone. You may not lend, sell or transfer it.
- You are responsible for all use of your account. If you find that someone else has used it, tell us as soon as you can.
5. Credit and payment
5.1 Prepaid credit, not a subscription
Klee is paid for with prepaid credit. You buy a credit pack (currently US$10, US$30 or US$100, shown in the App before you buy) and receive credit equal to what you pay. There are no recurring charges, and we never charge you automatically. When your balance runs out, Klee stops handling new requests until you buy more.
5.2 Trial credit
A new account receives US$1 of trial credit. Trial credit is limited to one per person, has no cash value and cannot be refunded. We may take back trial credit obtained by signing up repeatedly or by similar means, and we may change or stop the trial credit for new accounts at any time.
5.3 How credit is used
Each request sent to a model is charged against your balance according to the model used and the number of tokens processed. Models differ in price, and longer conversations and larger files use more. You can see your balance and usage in the App's settings.
Rates may change. A change applies only to use after it takes effect.
A request already in progress may take your balance slightly below zero. The difference is made up from your next purchase.
5.4 Payment
Payments are handled by Stripe. Prices are in US dollars. Any taxes that apply are shown on the payment page. Your bank or card issuer may charge its own fees, for example for currency conversion.
5.5 What credit is
Credit can be used only for Klee. It is not money or a deposit, earns no interest, cannot be exchanged for cash, and cannot be transferred between accounts or resold.
5.6 Expiry
Purchased credit does not currently expire. If we introduce an expiry period, it will apply only to credit bought after we announce it.
5.7 Refunds
Credit that has been used cannot be refunded. If you were charged by mistake, charged twice, or paid for credit that did not arrive, write to us and we will correct it.
For any other refund request about purchased credit you have not used, write to wei@signerlabs.com and we will look at each request individually. Nothing in these terms limits any right to a refund or to withdraw from a purchase that you have under the law where you live.
If you have a question about a charge, please contact us first. We may suspend an account while a payment on it is in dispute.
6. What Klee does on your computer
Klee acts on your computer on your instructions. Depending on the task, it may create, change, move and delete files, run commands, download components it needs for the task, and access the internet. It has the access that your macOS user account and the system grant it.
- Auto mode (the default): Klee keeps going on its own, and asks you only before an action it judges cannot be undone.
- Manual mode: Klee asks you before every file change and every command.
Klee's judgment about what is safe, or what can be undone, may be wrong. You are responsible for the tasks you give it, for the mode and the working folder you choose, and for checking what it did. Keep backups of anything important. Do not have it work on systems or data that you have no right to use or change.
7. AI-generated content
Klee's answers and the files it makes are generated by AI and may be inaccurate, incomplete or wrong. Check them before you rely on them. They are not legal, medical, financial or other professional advice. You are responsible for how you use them.
8. Your content
As between you and us, your files, what you type and what Klee produces for you belong to you. We do not store this content; to carry out a task, it is sent to the model for processing as described in the Privacy Policy. You give us only the permission needed to transmit it in order to provide the service.
Make sure you have the right to have the content you give Klee processed by a third-party service. Do not have it work on content that the law or an agreement forbids you to share.
9. Acceptable use
You agree not to:
- use the App for any unlawful purpose or in violation of any applicable law;
- violate Anthropic's Usage Policy, since your requests are processed by its models;
- call our service other than through the App, use it as a general-purpose model interface, or resell or lend access to it;
- get around billing, credit, rate limits or other technical limits, or create multiple accounts to obtain trial credit;
- interfere with, probe or attack our service;
- reverse engineer, decompile or disassemble the App, except as permitted by law;
- use Klee to break into or damage other people's systems or data.
We may limit the rate of requests to protect the service.
10. Third-party services and software
The models are provided by Anthropic and payments are handled by Stripe; their own terms apply to the parts they are responsible for. Klee is an independent product of Signer Labs and is not affiliated with or endorsed by Anthropic. Claude is a trademark of Anthropic.
Tools you connect, skills you add, and websites Klee visits for you are the responsibility of their providers, and you use them at your own risk. Open-source software included in the App is licensed under its own licenses.
11. License and intellectual property
As long as you comply with these terms, we grant you a personal, non-exclusive, non-transferable, revocable license to install and use the App on Macs that you own or control. The App, including its design, code, graphics and branding, is owned by Signer Labs and protected by intellectual property laws. These terms do not grant you any rights to our trademarks or branding.
12. Changes and interruptions
We may add, change or remove features, and the models available may change with their provider. The service may be interrupted by maintenance, faults or causes outside our control, and we do not promise that it will always be available.
If we decide to shut Klee down, we will give notice in advance on this website and by email, and say how unused purchased credit will be handled.
13. Suspension and termination
You may stop using the App at any time. Deleting the App does not delete the data it keeps on your Mac; you delete that yourself. To delete your account, write to us.
We may suspend or end your use of the service if you violate these terms, if we suspect fraud, or if the law requires it. Section 5.7 then applies to any purchased credit you have not used.
14. Disclaimer of warranties
The App is provided “as is” and “as available” without warranties of any kind, either express or implied, including but not limited to warranties of merchantability, fitness for a particular purpose, or non-infringement. We do not warrant that the App will be uninterrupted or error-free, that its output will be accurate, or that data loss will never occur.
15. Limitation of liability
To the maximum extent permitted by law, Signer Labs shall not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of data, arising out of or related to your use of the App. Our total liability for any claim arising from these terms or the App shall not exceed the amount you paid us in the twelve months preceding the claim.
Some places do not allow some of these exclusions or limits. Where that is so, they apply only as far as the law allows.
16. Governing law
These terms are governed by the laws of the State of Delaware, USA, without regard to conflict of law principles. If you are a consumer, the mandatory protections of the law of the country where you live still apply to you.
17. Changes to these terms
We may update these Terms of Use from time to time. We will notify you of material changes by posting the updated terms on this page and updating the “Last updated” date. Continued use of the App after changes take effect constitutes acceptance of the revised terms.
18. Language
These terms are provided in English and Chinese. If the two versions differ, the English version prevails.
