Privacy Policy
How this website handles data, cookies, and advertising.
Last updated: July 17, 2026
Overview
This website (s-iguchi09.github.io) publishes technical articles and open-source software. Browsing the site requires no registration and no submission of personal information (for how information you provide when contacting the developer is handled, see the Contact section below). This policy explains the limited data that may be processed when you visit — primarily in connection with advertising.
Data This Site Collects
Except when you contact the developer by email (see the Contact section below), the site operator does not collect or store personal information through your use of the site, and the site does not run its own analytics or tracking. It is hosted on GitHub Pages; like any web host, GitHub may record standard server access logs (such as IP address, browser type, and access time) for security and operational purposes. See GitHub's Privacy Statement for details.
Cookies
This site sets no first-party cookies of its own for tracking. Any cookies stored in your browser during a visit originate from the third-party advertising described below. You can view, manage, or block cookies at any time through your browser settings; blocking cookies does not prevent you from reading the content.
Advertising (Google AdSense)
This website uses Google AdSense, an advertising service provided by Google. Third-party vendors, including Google, use cookies — and may also use web beacons, IP addresses, and other identifiers — to serve ads based on your prior visits to this and other websites. Google's use of advertising cookies enables it and its partners to serve ads based on your visits to this site and/or other sites on the Internet.
You can control or opt out of personalized advertising through the following:
- Google Ads Settings — manage the ads Google shows you.
- aboutads.info / Your Online Choices (EU) — opt out of third-party ad personalization.
For more on how Google handles data when you use this site, see How Google uses information from sites or apps that use our services and Google's Privacy & Terms. Visitors in the EEA, the UK, and Switzerland can manage ad personalization through the settings above.
Third-Party Services
Applications introduced on this site may rely on external APIs or SDKs. Where that is the case, please refer to each service's own privacy policy for details.

Contact
For questions regarding this privacy policy or data handling, please contact the developer at the following email address:
If you contact the developer by email, your email address and the contents of your message are received and retained in order to respond. This information is used solely to handle your inquiry. Because the contact address is a Google Gmail account, messages you send are received by Google and stored and processed in its data centers. The developer does not share this information with any other third parties.
