Privacy Policy

Effective: 2026-08-09

What we collect

WhereIsDNS is a free DNS lookup tool. The site does not require an account, does not store the hostnames or record types you look up, and does not link queries to your identity.

The one exception is DNS change alerts, which are opt-in and described in their own section below. If you never subscribe to an alert, we hold no personal data about you at all.

When you submit a lookup, your browser asks our Cloudflare Worker (running at the Cloudflare edge) to query 14 public DNS-over-HTTPS resolvers in parallel. The hostname you submit is included in those DNS queries and is therefore visible to the resolvers receiving them. We do not log the hostname server-side.

DNS change alerts (email)

DNS change alerts are the only feature that collects personal data, and only if you choose to use it. When you subscribe to a watch we store: your email address, the hostname and record type you asked us to watch, the record's most recent value (so we can tell when it changes), and the timestamps of creation and last check. That is the complete list.

We confirm before we send anything. Subscribing emails you a confirmation link, and the watch does not start — and no further email is sent — until you click it. Requests that are never confirmed are deleted automatically after 48 hours. This prevents anyone from subscribing an address they don't control.

Your address is used solely to deliver the alerts you asked for. There is no newsletter and no marketing, and we do not sell, rent, or share it with third parties.

Retention and deletion: a confirmed watch is kept until you remove it. Every alert email contains a one-click unsubscribe link that requires no account and no login; using it deletes the watch and the stored email address immediately. You may also email us to have any data removed.

Processors: subscriptions are stored in Cloudflare Workers KV, and alerts are delivered using Cloudflare Email Sending. Alerts are sent from alerts@boringhaus.com — Boringhaus is the portfolio WhereIsDNS belongs to, and it is the domain with authenticated sending configured. Both are subject to Cloudflare's privacy policy.

Server logs

Cloudflare, our hosting provider, automatically logs request metadata: IP address, user agent, timestamp, response status, geographic region: for security, abuse prevention, and aggregate analytics. These logs are subject to Cloudflare's privacy policy. We do not attach any user-identifying data to these logs.

Cookies

WhereIsDNS itself does not set tracking cookies. We use localStorage (a browser API similar to cookies) only to remember whether you have dismissed our cookie-consent banner.

Third-party services we embed may set cookies of their own: see below.

Your rights (GDPR & CCPA)

EU / UK / Switzerland (GDPR). If you are in the European Economic Area, the United Kingdom, or Switzerland, you have the right to access, rectify, erase, restrict, port, and object to processing of your personal data. Because we do not collect identifying data on our own systems, there is little to act on at our end; for data held by Google AdSense or Cloudflare relating to your use of WhereIsDNS, use those services' own privacy controls (linked above). To make a request directly to us, email ideas@boringhaus.com.

California (CCPA / CPRA). California residents have the right to know what personal information we collect, request deletion, and opt out of the sale or sharing of personal information. We do not sell personal information. To exercise any CCPA right, email ideas@boringhaus.com.

Children

WhereIsDNS is a technical utility intended for site administrators, developers, and IT professionals. The service is not directed at children under 13 and we do not knowingly collect data from them.

Changes to this policy

We may update this policy as the site evolves or as legal requirements change. Material changes will be reflected in the "Effective" date at the top of this page.
