Privacy Policy

Diagnostic inputs: domains, IPs and URLs you submit are processed to return results. Server-side checks send the value you submit to our servers and on to the third parties listed below. Client-side utilities (encoders, calculators, hashing) run entirely in your browser and are never transmitted.

Browser storage: the value you submit is also saved in your browser's local storage under the key netinsight:history:<slug> — up to the six most recent values per tool — so a tool can show them back to you. This copy never leaves your browser.

Log data: our servers record standard request metadata such as IP address, timestamp and user agent for security and abuse prevention.

We do not set cookies. The service uses no cookies of any kind, and your theme preference is kept in your browser's local storage rather than in a cookie.

Where enabled, privacy-respecting analytics help us understand aggregate usage. See our Cookie Policy for detail.

We may rely on analytics providers where analytics are enabled. Each processes data under its own terms.

Some checks necessarily contact a third party with the value you submit: DNS and mail record lookups are sent to the public DNS resolvers Cloudflare (1.1.1.1), Google (8.8.8.8) and Quad9 (9.9.9.9); IP and ASN lookups send the IP address to ipwho.is; and blacklist checks send the IP address or domain to DNS blacklist operators. A blacklist check also resolves the domain you submitted, or looks up the reverse address of an IP you submitted, through the DNS resolver configured for this deployment — or the system resolver where none is configured — so that resolver may receive the submitted value as well. Each of them processes that data under its own terms.

Diagnostic results may include data sourced from public registries (WHOIS), DNS resolvers and blacklist operators. That data belongs to its respective owners.

Query inputs are retained only as long as needed to deliver results and secure the service, then aggregated or deleted.

The copy kept in your browser's local storage stays on your device until you clear the site's stored data through your browser. The service offers no in-app control to erase it.

You may request access to, correction of, or deletion of your personal data, and you may object to certain processing.

California residents have the right to know what personal information is collected and to opt out of its sale — we do not sell personal information.
