Privacy Policy

Last updated: 11 November 2026

Nexus Domain Tools (this site) is a set of free network diagnostics — DNS, WHOIS, email security, TLS, and related checks. It has no accounts, no login, and no cookies. This policy explains the small amount of processing that happens anyway, because honesty about data is the point of the product.

What we process

  • The domains, IPs, and URLs you look up. These are processed in real time to answer your query. Caches of results are in-memory and expire within minutes. They are not written to disk, not tied to you, and not sold.
  • Your IP address. Used transiently, in memory, for rate limiting and abuse prevention. It is not persisted, not exported, and not linked to your queries after the request.
  • Short-lived operational logs at our hosting providers, used only for troubleshooting incidents.
  • Cloudflare Turnstile protects heavier endpoints from bots. Verification runs on Cloudflare's infrastructure; see Cloudflare's privacy policy.
  • Cloudflare Web Analytics. We use a cookieless, no-fingerprinting analytics beacon to understand aggregate site traffic (visits, geography, referrers, device types). It sets no cookies and collects no personal data we can link back to you.
  • Your recent lookups are kept in your browser's local storage (the "Recent" list) so you can reopen them. This never leaves your device and is not sent to us.

What we never do

  • No accounts or profiles — there is nothing to sign up for.
  • No cookies on this site.
  • No advertising trackers.
  • No profiling of individual users.
  • No selling or sharing of personal data. Ever.
  • No use of this service's output for AI/LLM training — see our ai.txt notice.

Where things run

  • Frontend: static files served by GitHub Pages.
  • API: Render (US/EU regions).
  • Analytics + bot protection: Cloudflare.

Your rights

We designed the service so that there is no personal data of yours to export, correct, or delete — we don't retain records that could identify you. We aim for strict data minimisation (POPIA, GDPR principles). If you have a question or concern, open an issue at github.com/Oba-SEG/dnstools/issues or reach us via segbytes.co.za.

Changes

If this policy changes materially, we update the date above and the footer of the site. Continued use after a change means you accept the updated policy.
