Privacy policy

Last updated: April 2026

What we collect

NumberWiki is a public, mostly-static reference site. We do not require accounts and do not collect personal information from visitors. Standard server logs (IP address, timestamp, request URL, user agent, referrer) are retained for operational purposes — diagnosing outages, identifying abuse, and understanding aggregate traffic patterns.

Cookies

NumberWiki itself does not set tracking cookies. Some pages may load resources from third-party CDNs (Tailwind CSS, KaTeX) which may set cookies according to their own policies. We do not use these cookies to track you across the web.

Analytics

If analytics are enabled in the future, this page will be updated to disclose which provider is used and what data is collected. As of the date above, no client-side analytics or behavioral tracking is in place.

Third-party services

NumberWiki is delivered through:

• Let's Encrypt for TLS certificates.
• jsDelivr as a CDN for KaTeX assets and a Tailwind CSS runtime.

These services may receive your IP address and user-agent string when serving assets.

Children's privacy

NumberWiki is intended for general audiences and does not knowingly collect information from anyone. The site is suitable for educational use including for minors.

Changes

Updates to this policy will be posted on this page. The "Last updated" date above reflects the most recent revision.
