Musashino Software (“we” or “us”) operates ms-soft.jp (“the site”). This Privacy Policy explains how information is handled in connection with the site, its browser-based tools, and related content.

1. Information we collect or process

We may collect or process the following information:

  • Usage information, including pages viewed, access time, referring source, device and browser type, approximate location, and identifiers such as cookies
  • Server logs, including IP address, request details, access time, and error information needed for delivery, maintenance, security, and abuse prevention
  • Contact information, including an email address, name or handle, message content, and information needed to reply
  • Support information made available to us through Buy Me a Coffee, such as a supporter name, message, and support amount

We do not directly collect or store payment card details. Payment information is processed by Buy Me a Coffee and its payment providers.

2. How we use information

We use information to:

  • Provide, maintain, secure, and troubleshoot the site and its tools
  • Understand usage and improve content, quality, and features
  • Respond to questions, requests, feedback, and bug reports
  • Receive optional support and communicate with supporters
  • Comply with law and protect legitimate rights

3. Files used with browser tools

Unless a tool clearly states otherwise, files selected in our browser-based tools are processed locally in the user’s browser and are not uploaded to our servers.

Some tools connect to external content delivery networks (CDNs) to load programs and stylesheets required for the tool to operate. These connections are made to retrieve those files.

4. Google Analytics

We use Google Analytics 4 to understand how the site is used and to improve it. Google Analytics may use cookies and collect information such as user and session counts, pages viewed, device and browser information, and approximate location.

The collected information is handled under Google’s terms and privacy policy. We do not configure Google Analytics to receive names, email addresses, or other directly identifying information.

Users can delete or disable cookies in their browser settings. Some external services may not work correctly when cookies are disabled.

5. Buy Me a Coffee

We display a Buy Me a Coffee widget so that users can optionally support the developer. When the widget is loaded or used, technical information such as an IP address, browser information, and referring page may be sent to Buy Me a Coffee and its delivery providers.

Buy Me a Coffee’s terms and privacy policy apply to support transactions, accounts, and payment information.

6. External content and CDNs

Some pages use embedded YouTube videos or software and styles delivered by services such as jsDelivr, cdnjs, and the DataTables CDN. When these resources are loaded, the service provider may receive technical information such as an IP address, browser information, and referring page, and may use cookies under its own policies.

The site contains links to external services including GitHub, X, note, Obsidian, and Blitzmemo. When a user visits a linked site, that operator’s terms and privacy policy apply.

7. Advertising and Amazon Associates

This site may contain affiliate links provided through the Amazon Associates Program. We may receive a commission when a product is purchased through an affiliate link.

Where affiliate links are used, they will be identified as advertising or affiliate links. Amazon may use cookies on its websites in accordance with its own privacy notice.

8. Sharing with third parties

We do not disclose personal information to third parties except:

  • With the user’s consent
  • Where information is provided as necessary in connection with the external services described in this policy
  • When required by law or necessary to protect life, safety, property, or other rights

9. Retention and security

We retain contact and other information only for as long as reasonably necessary for its purpose, response history, and legal requirements. Information that is no longer needed is deleted or anonymized by reasonable means.

We take reasonable measures to protect information against unauthorized access, loss, disclosure, or alteration. However, no transmission or storage system on the internet can be guaranteed to be completely secure.

10. Access, correction, and deletion requests

To request access to, correction of, or deletion of contact information or other personal information we hold, please contact us using the address below and provide information reasonably necessary to verify the request. We will respond in light of applicable law and legitimate operational needs.

11. Changes to this policy

We may update this policy when our services, external providers, or applicable requirements change. We will announce material changes on the site. An updated policy applies when it is published on this page.
