Privacy policy

Last updated: August 9, 2026

Chromatin.net is an educational website. We collect limited technical information needed to operate the site securely and improve content.

Information we process

• Server logs (IP address, user agent, request path, timestamps) for security and reliability.
• Privacy-preserving analytics through the shared keyword-site network (hashed IP, path, referrer metadata).
• Search queries submitted on this site (stored to improve content coverage; not sold as personal profiles).
• Contact ticket contents you voluntarily submit (name, email, message) via the shared ticket system.
• Cookies needed for session security (CSRF/session) and network analytics session identifiers.

Advertising

We may display Google AdSense and/or network sponsored units when enabled for this site. Advertising partners may use cookies or similar technologies subject to their own policies. Ad placements are labeled “Sponsored” and are kept out of essential tool controls.

Analytics choices

Network analytics uses a first-party session identifier (ks_sid) and hashed technical metadata. To opt out of Chromatin.net analytics forwarding on this browser, set a first-party cookie named ch_analytics_opt_out to 1 (for example via your browser’s developer tools or a privacy extension). Session/security cookies required for forms may still be used.
