Isaac Koi is a static, informational reference site. It has no accounts, no registration, no comments and no newsletter, and it does not ask visitors for personal information.

Hosting

The site is served as static files by GitHub Pages. GitHub’s own privacy policy governs the hosting service; this site does not run a server of its own and does not store visitor data.

Analytics

This site uses Google Analytics 4 to understand aggregate usage, such as which pages are visited and for how long. Google Analytics sets cookies (for example the _ga cookie) in your browser for this purpose. You can block or delete these cookies in your browser settings, or use Google’s opt-out mechanisms for Google Analytics.

Embedded content and third-party requests

Pages may embed YouTube video players. When a page with an embedded player loads, YouTube (Google) receives request data from your browser and may set its own cookies under its own privacy policy. Page fonts are loaded from Google Fonts, which means your browser requests those files directly from Google.

Affiliate links and advertising cookies

Some outbound links to retailers are affiliate links. Following them may set cookies used to attribute a purchase to this site, which can earn us a commission at no additional cost to you. Retailer sites have their own privacy policies once you leave this site. See the Affiliate & AI Disclosure for details.
