Privacy Policy

01 / Information We Collect

This site handles the following types of information:

• Display settings: Theme preferences such as dark mode are stored on your own device (local storage). This information is never transmitted externally.
• Access statistics: We record the view count of each article as an aggregate value that does not identify individuals.
• Contact form: Your name, email address, and message. See "05 / Information Collected via Inquiries" for details.
• Paid article purchases: Sales and payment for paid articles are handled by an external service, codoc. See "06 / Information Handled by codoc for Paid Articles" for details.

02 / Analytics Tools

This site may use an analytics tool (Cloudflare Web Analytics) to understand how it is used. This tool does not use cookies and does not collect personally identifying information.

03 / About Cookies

This site itself does not issue cookies. Local storage is used to save display settings; if you disable it in your browser settings, your preferences may not be saved. However, the codoc widget embedded on paid article pages uses cookies issued by codoc Inc. to verify login and purchase status.

04 / Server Logs

This site is operated on Cloudflare’s hosting service, and access logs including IP addresses are processed on their infrastructure. Please refer to Cloudflare’s privacy policy for details.

05 / Information Collected via Inquiries

The contact form collects your name, email address, and message. This information is used solely to respond to your inquiry. Email delivery is handled through Resend Inc. (resend.com), meaning your data passes through their service. Resend's privacy policy applies to their handling of this data. We do not share your information with any other third parties.

06 / Information Handled by codoc for Paid Articles

Sales and payment for paid articles on this site are handled by "codoc," a service provided by codoc Inc. When you view a paid article page, your access information (such as IP address) is transmitted to codoc in order to display the widget, regardless of whether you make a purchase. Account and payment information entered at the time of purchase is collected and managed directly by codoc; the Studio never receives this information. Please refer to codoc’s privacy policy for details on how they handle information.
