This is a static website. It has no accounts, no logins, no forms, and it does not itself collect, store, or sell personal information. The site's own data — the trades and statistics — concern a simulated computer account, not any person.
The site is hosted on GitHub Pages. GitHub may log standard technical data (such as IP addresses) for security and operational purposes; see GitHub's privacy statement.
This site may display advertisements served by third-party networks (for example, Google AdSense). Ad networks may use cookies, web beacons, or similar technologies — including, where permitted, personalized-advertising identifiers — to serve and measure ads:
This site's operators do not receive or store the data collected by ad networks beyond aggregate, non-identifying reporting.
Pages load fonts and chart libraries from CDNs (Google Fonts, jsDelivr); those providers may log technical request data per their own policies.
Depending on your jurisdiction (GDPR, UK GDPR, CCPA/CPRA, etc.) you may have rights regarding personal data held by the third parties above — exercise them directly with those providers, since this site holds none. California residents: this site does not sell or share personal information as defined by the CCPA/CPRA.
This site is not directed to children under 13 (or the applicable age in your jurisdiction) and knowingly collects no data from them.
Questions: open an issue at the site's GitHub repository. This policy may be updated; the date above governs.
