Terms of Service

These terms apply to Kagemusha, a macOS application published by LIFE SCAPE, K.K. ("we"). By installing or using Kagemusha, you agree to them.

1. What Kagemusha does

Kagemusha turns a website you choose into an application that runs on its own on macOS. The app it creates runs on a Chromium-based browser already installed on your Mac (Chrome, Brave, Microsoft Edge, Vivaldi, Opera, Chromium, or Chrome Canary).

We are not affiliated with those browsers or with the websites you turn into apps. We are not responsible for how they behave, how they change, or whether they stay available.

2. Your license

3. Payment and refunds

4. What you may not do

5. Operation by AI agents

  1. For the apps you allow, Kagemusha lets an AI agent or other program running on your Mac (an "AI agent") operate the service while you stay signed in ("AI control"). AI control is on only for the apps where you allow it, one app at a time.
  2. When you turn on AI control, what an AI agent does is treated as done on your instructions and under your responsibility. You are responsible for what the AI agent does and its results, including sending, posting, purchasing, and changing data.
  3. Before you use AI control, check and follow the terms and other conditions of the service it will operate. Do not use AI control on a service that prohibits or restricts automated operation, bots, or scraping.
  4. You sign in to each service yourself. We never sign in on your behalf and are not given your password or other credentials. Do not give an AI agent your password or other credentials.
  5. An app with AI control turned on can be operated by programs running on your Mac. What an AI agent can do on your Mac is decided by the permissions you give that agent. We do not guarantee that an AI agent stays inside one app. Let only programs you trust use AI control.
  6. Anything that arises between you and the service being operated, including but not limited to suspension or deletion of your account, treatment as a breach of its terms, and the results of an AI agent's actions, is to be settled between you and that service's provider, and we are not responsible for it.
  7. Kagemusha is meant for a personal Mac used by one person, not a shared computer.

6. Changes and availability

We may change or stop offering the software without notice. We are not liable for loss arising from that.

7. Disclaimer and limit of liability

  1. The software is provided as is. We do not warrant that it fits a particular purpose or that it is free of defects.
  2. How a generated app behaves depends on the browser underneath it and on the website being operated. Updates to either can change that behaviour.
  3. We are not responsible for anything arising from a decision by the provider of the service being operated or from the behaviour of an AI agent, including the matters in section 5, item 6.
  4. If our ordinary negligence causes you loss, our liability is limited to the amount you paid us for the software.
  5. The two items above do not apply to loss caused by our wilful misconduct or gross negligence.

8. Changes to these terms

We may revise these terms. The revised version takes effect when it is posted on this page.

9. Governing law

These terms are governed by the laws of Japan. The Tokyo District Court has exclusive jurisdiction in the first instance over any dispute.
