Privacy Policy

Who we are

PublicDNS.nl is an online tool for DNS, SSL/TLS, HTTP and email-related diagnostics. In this document, “we” refers to the operator of PublicDNS.nl.

Data we process

Data you enter

When you use the tools, you may provide:

• Domain names and hostnames
• IP addresses
• URLs

These inputs are used to perform lookups (DNS, WHOIS, HTTP/HTTPS, etc.). They may appear in transient logs to monitor performance and misuse.

Technical logs

Our servers may log standard information such as:

• IP address of the request
• Date and time
• Requested URL and user agent
• Error messages and performance metrics

These logs are used for debugging, security monitoring and capacity planning. They are not used to create user profiles.

Cookies

PublicDNS.nl uses cookies for:

• Functional cookies: for example, to store your language preference.
• Analytics cookies: to understand how the site is used.
• Advertising cookies: used by third-party services such as Google AdSense.

Analytics

We use web analytics (for example, Google Analytics) to collect aggregated information about usage patterns: which pages are visited, which tools are used, and technical performance. Analytics tools may set their own cookies and process your IP address in an anonymised or pseudonymised form, depending on the configuration.

Advertising (Google AdSense)

PublicDNS.nl may display advertisements via Google AdSense or similar ad networks. These third parties may use cookies and similar technologies to:

• Serve and measure ads
• Detect fraud and abuse
• Personalise ad content where permitted

For details on how Google uses data, please refer to Google’s own privacy and terms pages. Where required by law, we will present a consent banner so you can manage your cookie and ad preferences.

Data sharing

We do not sell personal data. Technical data may be shared with service providers (hosting, analytics, security monitoring, ad networks) to operate and protect the service.

Retention

Technical logs and analytics data are retained for a limited period, only as long as necessary for security, troubleshooting and capacity planning.

Your rights

Depending on your jurisdiction, you may have rights such as access, rectification or deletion of personal data. For privacy-related requests, contact us at privacy@publicdns.nl.

Changes

This policy may be updated from time to time. When we make significant changes, we will update the “last updated” date below.
