This Privacy Policy explains what information 51Shogi handles when you visit 51shogi.org or contact the site. It is intended to describe this website’s current practices in clear language.
1. Information you provide
The contact form asks for your name, email address, topic, and message. This information is used to review your request and reply when appropriate. Contact messages are not published on the website.
2. Information collected automatically
Like most websites, the hosting and security infrastructure may process technical records such as your IP address, browser and device information, requested URL, referring page, date and time, and error or security events. These records are used to deliver the site, diagnose problems, prevent abuse, and protect the service.
3. How information is used
- To operate, secure, and improve 51Shogi.
- To respond to corrections, accessibility reports, and other messages.
- To investigate technical failures, spam, or misuse.
- To comply with applicable obligations and valid legal requests.
4. Contact form security
The form uses security checks, a hidden anti-spam field, input validation, and short-term rate limiting. The site does not intentionally store contact submissions in a public database. A message is sent to the site operator’s private administrative address, and the sender’s email address is used only to manage the correspondence.
5. Cookies and local storage
WordPress, the hosting platform, or security features may use cookies or similar storage when needed for site operation, administration, preferences, or abuse prevention. You can control cookies through your browser, but blocking essential storage may affect some functions.
6. Advertising
51Shogi may display advertising through Google AdSense. When Google ads or ad tags are active, Google and its partners may use cookies to serve, limit, and measure ads, including ads based on prior visits to this or other websites. You can manage personalized advertising in Google Ads Settings. Google’s handling of information is described in the Google Privacy Policy.
7. Service providers and disclosure
Information may be processed by providers that support hosting, security, email delivery, and advertising, but only as needed to provide those services. 51Shogi does not sell contact-form information. Information may also be disclosed when required by law, to protect rights or safety, or to investigate abuse.
8. Retention
Contact correspondence is kept only as long as reasonably needed to handle the request, maintain an appropriate record, or meet an applicable obligation. Technical and security logs follow the retention periods set by the relevant hosting and infrastructure providers.
9. Your choices and requests
You may ask about, correct, or request deletion of personal information you submitted to 51Shogi, subject to applicable exceptions. Use the Contact page and include enough detail for the request to be identified safely.
10. Children
51Shogi provides general educational content and does not knowingly request personal information from children under 13. A parent or guardian who believes a child submitted personal information may contact the site to request review or deletion.
11. Security and external links
Reasonable safeguards are used, but no internet transmission or storage method can be guaranteed completely secure. 51Shogi also links to external websites that operate under their own privacy policies and terms.
12. Policy changes and contact
This policy may be updated when site practices or services change. The revision date at the top will be changed when a material update is published. Questions or privacy requests can be sent through the Contact page.
