Privacy Policy

Effective date: January 20, 2026

This Privacy Policy explains how DNS Lookup (“we,” “us,” or “our”) collects, uses, and shares information when you visit or use the Service. We aim to keep the Service useful, secure, and transparent. By using the Service, you consent to the practices described below.

Information we collect

The Service does not require user accounts. However, we may collect certain technical information automatically when you use the tools, including:

• Your public IP address and basic request metadata.
• Inputs you provide to tools, such as hostnames, IPs, or ports.
• Diagnostic results generated in response to your request.
• Browser and device information, such as user agent and language settings.

This information helps us operate the Service, detect abuse, and improve reliability. We do not request personal identifiers such as name, email address, or billing details.

How we use information

We use collected information to provide the Service, troubleshoot issues, and maintain security. Examples include rate limiting, identifying automated abuse, and measuring performance. We may also use aggregated or anonymized data to understand usage trends and prioritize improvements.

Cookies and analytics

We use cookies and similar technologies to support analytics and advertising. These technologies may collect information about your device, browser, and usage patterns. Analytics help us understand how visitors interact with the site so we can improve layout, performance, and content clarity.

You can manage cookie preferences through your browser settings. Disabling cookies may limit some features or reduce the relevance of ads, but the core diagnostic tools should continue to function.

Advertising

The Service is supported by advertising. Ads may be served by third-party networks such as Google AdSense, which may use cookies or device identifiers to personalize ads and measure performance. Those providers may collect information about your visits to this and other websites. For more information, review the privacy policies of the advertising providers you encounter.

Data retention

We retain diagnostic logs for a limited period to maintain service integrity, investigate errors, and prevent abuse. Retention periods may vary depending on operational needs. We do not sell personal data, and we do not use tool inputs for marketing unrelated to the Service.

Sharing information

We may share information with service providers who help operate the Service, such as hosting, analytics, and advertising partners. These providers are permitted to process information only as needed to perform their services. We may also disclose information if required by law or to protect the security and integrity of the Service.

Security

We take reasonable measures to protect the Service and the information processed through it. No system is perfectly secure, and you should avoid submitting sensitive personal data through diagnostic inputs. For SSL certificate conversions, consider using local tools if your environment requires strict data handling.

Your choices

You can limit data collection by reducing usage, clearing cookies, or using privacy-focused browser settings. You can also access the Service without creating an account. If you have questions about data handling or wish to request deletion of specific logs, contact us using the Contact page.

International visitors

The Service may be accessed globally. Information may be processed in the region where the Service is operated or where our service providers are located. By using the Service, you consent to the transfer of information across borders as necessary to provide the Service.

Children’s privacy

The Service is intended for general audiences and is not directed to children. We do not knowingly collect personal information from children. If you believe a child has provided personal information, contact us and we will take appropriate steps.

Changes to this policy

We may update this Privacy Policy from time to time. The effective date above will reflect the most recent update. Continued use of the Service after changes are posted indicates acceptance of the revised policy.
