What We Collect

Analytics

We use Google Analytics 4 to understand how the service is used. Google Analytics collects anonymized data including pages viewed, session duration, general geographic region (country/city level), browser type, and operating system. This data is processed by Google and subject to Google's Privacy Policy. We do not use this data to identify individual users.

Server Access Logs

Our web server records standard access logs containing your IP address, the URL requested, HTTP status code, and user agent string. These logs are retained for up to 30 days for security monitoring and operational purposes, then automatically deleted.

Browser Storage (LocalStorage)

Mr.DNS stores two items in your browser's LocalStorage — your light/dark theme preference and a list of your recent lookups. This data never leaves your browser and is not sent to our servers. You can clear it at any time by clearing your browser storage.

What We Don't Collect

  • DNS queries are not logged. The domain names and IP addresses you look up are processed server-side to perform the query but are not stored in any database or log file.
  • No user accounts. We do not collect names, email addresses, or passwords.
  • No payment data. The service is free and we do not handle payment information.

Third-Party Services

  • Google Analytics — usage analytics. See above.
  • MaxMind GeoLite2 — IP geolocation is performed using a local offline database. Your IP address is never sent to MaxMind.
  • Cloudflare DNS-over-HTTPS — some checker tools (DNSSEC, blacklist) use Cloudflare's DoH resolver. Queries are sent to Cloudflare's servers to resolve. (Cloudflare Privacy Policy)

Cookies

Mr.DNS does not set any first-party cookies. Google Analytics may set cookies in accordance with its own policy.

Your Rights

Because we do not store personal data tied to individual users, we cannot retrieve or delete records on request beyond what is described above. Server access logs are automatically purged after 30 days. If you have a specific concern, contact us at the address below.
