Privacy Policy

Last updated: July 2026

Core Web Utilities is built to respect your privacy. In plain language:

What we do not collect

• No accounts, logins or personal profiles.
• No database and no files of the domains, IP addresses, email addresses or text you enter. Your queries are processed in memory and discarded.
• No advertising trackers and no third-party analytics cookies.

What we temporarily keep

• Anti-abuse counters. To stop automated misuse we keep an in-memory count of recent requests per IP address for up to a minute. It is never written to disk and is cleared when the service restarts.
• A functional cookie. We set a single random identifier cookie to apply the anti-abuse rules fairly. It contains no personal information.
• Standard server logs. Like any web server, ours may record request metadata (such as IP and timestamp) transiently for security and reliability. We do not build profiles from it.

Third parties

Some tools query public infrastructure on your behalf — for example public DNS resolvers, WHOIS servers, or a host you ask us to test. We send only what is needed to perform the lookup.
