Operator and scope
Kotolog is operated personally by Zhou Lei under the Minerei brand. In these terms, Minerei is a brand name, not a representation that a company has been incorporated. “We” means the operator.
These terms cover the Kotolog website, web app, iPhone app, and other clients and interfaces we actually provide. The website's availability notices and working entry points describe what is currently open.
Please read these terms and the privacy policy before registering or using Kotolog. If you do not accept them, do not register or continue using the service.
Free public beta
Kotolog is currently a free public beta. The web and iPhone beta apps share the same test accounts and data. This does not mean that every client or feature has been released.
Features may change, and bugs, interruptions, sync delays or data damage may occur. Keep a separate copy of important material, and do not use this service as its only storage location. We do not routinely clear test users' data merely to release a new version.
There is currently no subscription fee. Any future paid service will have its price, terms and payment process explained separately. Using the free beta will not by itself authorize automatic charges.
Age and accounts
This public beta is only for people aged 18 or older.
- Use an email address and sign-in method you are entitled to use, and provide truthful information needed for your account.
- Protect your account. Do not give others your personal login credentials, verification codes or device credentials.
- Contact us promptly if you notice unauthorized use. Depending on the circumstances, we will help restrict access or recover the account.
- Give automation tools only the permissions they need for the work you intend.
Your content and necessary permission
You retain the rights to content you own. Before uploading or sharing someone else's material, make sure you have the right to do so.
You allow us to store, back up, process and display content as necessary to provide the features you use, including device sync, sharing you initiate and assistant processing. This permission does not transfer ownership to us or authorize us to publish or sell your content for unrelated purposes.
The privacy policy explains the information collected, service providers, retention and your data rights. Do not upload personal information you have no right to process, or sensitive or confidential material unsuitable for a beta service or third-party AI processing.
Assistant, command line and external AI tools
Koto-chan's answers are generated by AI and may be wrong, incomplete or out of date. Verify important information. Do not rely on the output alone for medical, legal, financial or similar professional decisions.
Content changes requiring confirmation in the product are shown as proposals. Review the target, content and schedule before confirming. Command line tools, MCP clients and other outside tools you connect may act with your account within the permissions you grant. Review those tools and permissions; the proposal process is not a guarantee covering every action by an outside tool.
AI features send necessary messages and related content to model or search providers, as described in the privacy policy. A free beta or AI-generated output does not exempt us from responsibilities imposed by applicable law.
Shared Spaces and outside connections
Content in a shared Space is visible to its other members and can be changed as their roles allow. Check the scope before inviting people, joining a Space or placing material there. Stopping use does not automatically withdraw copies that other members have already seen or saved.
Connecting Google Calendar, GitHub or other services is optional, and their own terms also apply. Apple's terms apply when the iPhone beta is distributed through TestFlight.
Prohibited conduct
- Breaking the law, infringing rights or uploading material you are not entitled to process.
- Uploading malware, stealing credentials, accessing accounts or content without authorization, or bypassing access controls.
- Deliberately disrupting the service, abusing interfaces or imposing unreasonable automated load.
- Impersonating the operator or misleading others about authorization from Kotolog or Minerei.
Stopping use, privacy requests and accounts
You can stop using the service at any time. Account deletion and data export are currently requested through parz1zhou@gmail.com; this does not mean there is a self-service feature in the product.
We aim to reply within 7 days of receiving a request and normally handle it within 30 days after verifying identity and scope. If more time is needed or applicable law prevents full handling, we will explain why and the next steps. These service targets do not limit your legal rights. The privacy policy explains deletion scope, backups and retention.
We may take necessary, proportionate measures, including restricting features or suspending an account, in response to a terms violation, compromised account or risk to users or service security. Except for urgent security action or legal requirements, we will explain the reason and provide a contact route.
Changes to or ending the service
We may maintain, change or stop beta features. Significant changes affecting accounts, data processing or main features will be explained in advance through reasonable channels such as the website, in-app notices or email. Urgent security measures may precede notification.
If we decide to end the entire beta service, we will give advance notice where reasonably practicable and explain the arrangements for exporting data, handling accounts and ending service.
Warranties and responsibility
The beta does not promise uninterrupted availability, freedom from errors or suitability for every purpose. AI output is not guaranteed to be accurate.
We remain responsible for obligations imposed on us by applicable law. These terms do not exclude or limit responsibility for damage caused by the operator's intent or gross negligence, or any other responsibility or user right that cannot lawfully be excluded or limited.
Responsibility for damage or disputes is determined under applicable law and the circumstances. A free beta, a request to keep backups or reliance on third parties is not a blanket exemption.
Governing law and disputes
The service is personally operated from Japan. These terms are governed by Japanese law. This does not deprive users of protections that applicable law does not allow a contract to exclude.
Please first contact us through the support email to try to resolve disputes. If that does not resolve them, a court with jurisdiction under applicable law may hear the dispute. These terms do not designate an exclusive court that overrides users' statutory rights.
Changes to these terms
Important changes will be explained in advance, with their content and effective date. Where separate consent is required, we will obtain it as required by law. You may stop using the service and request data handling before a change takes effect. A general “continued use means acceptance” clause will not replace a legally required consent process.
