NetworkCheckr (“we,” “us,” or “our”) respects your privacy. This Privacy Policy explains what information we collect when you visit networkcheckr.com, how we use it, and what choices you have. By using this website you agree to the practices described below.
Information We Collect
Information You Provide Directly
We collect personal information only when you voluntarily submit it through our website. This includes:
- Contact form submissions — your name, email address, and the content of your message when you use the contact page.
- Email subscriptions — your email address if you sign up for our newsletter or download a resource such as our network cheat sheet.
We do not require you to create an account to use any of our networking tools or to read our guides.
Information Collected Automatically
When you visit NetworkCheckr, certain technical information is collected automatically by our hosting provider, analytics services, and advertising partners. This may include:
- IP address (may be anonymized depending on the service)
- Browser type and version
- Operating system
- Referring URL (the page that linked you here)
- Pages visited and time spent on each page
- Device type (desktop, mobile, tablet)
- Approximate geographic location (derived from IP address, typically city or region level)
This data is collected through cookies, server logs, and similar technologies. See the Cookie Policy for full details on the cookies we use.
Tool Usage Data
All seven of our networking tools run entirely in your browser using client-side JavaScript. The data you enter into our tools — such as IP addresses, MAC addresses, or domain names — is processed locally on your device and is not stored on our servers. Some tools make API calls to third-party services (such as ipinfo.io for geolocation data or Google Public DNS for DNS lookups) to return results. Those requests are made directly from your browser to the third-party API and are subject to the third party’s own privacy policy.
How We Use Your Information
We use the information described above for the following purposes:
| Purpose | Data Used | Legal Basis |
|---|---|---|
| Respond to contact form inquiries | Name, email, message content | Consent / Legitimate interest |
| Send email newsletters or resources you requested | Email address | Consent |
| Analyze website traffic and improve content | Anonymized analytics data | Legitimate interest |
| Display relevant advertisements | Cookies and browsing data (via ad networks) | Consent (cookie banner) |
| Prevent spam and abuse | IP address, form submissions | Legitimate interest |
| Maintain site security | Server logs, IP address | Legitimate interest |
We do not sell your personal information to third parties. We do not use your data for automated decision-making or profiling.
Third-Party Services
NetworkCheckr uses the following third-party services that may collect data through cookies or API requests:
Google Analytics
We use Google Analytics to understand how visitors use our site, including which pages are most popular, how long visitors stay, and where traffic comes from. Google Analytics uses cookies and collects anonymized data. We have enabled IP anonymization so your full IP address is not stored by Google. You can opt out of Google Analytics by installing the Google Analytics Opt-Out Browser Add-On.
Google AdSense
We display advertisements through Google AdSense to support the operation of this website. AdSense may use cookies and web beacons to serve ads based on your prior visits to this site or other websites. Google’s use of advertising cookies is governed by the Google Privacy Policy. You can opt out of personalized advertising by visiting Google Ads Settings or by visiting aboutads.info.
Affiliate Programs
Some pages on NetworkCheckr contain affiliate links to products and services we recommend, such as web hosting providers, VPN services, networking equipment, and online courses. When you click an affiliate link and make a purchase, we may earn a commission at no additional cost to you. Affiliate partners may use cookies to track referrals. For more information, see our Affiliate Disclosure.
Third-Party APIs Used by Tools
Certain tools on NetworkCheckr make client-side requests to external APIs to provide results. These include:
- ipinfo.io and ipify.org — used by the My IP Address tool for IP geolocation
- Google Public DNS (dns.google) — used by the DNS Lookup and Reverse DNS Lookup tools
- macvendors.com — used by the MAC Address Lookup tool for vendor identification
These requests go directly from your browser to the third-party service. We do not proxy, intercept, or log these requests on our side. Each service has its own privacy policy governing how it handles the data it receives.
Cookies
Cookies are small text files stored on your device by your web browser. NetworkCheckr uses cookies for analytics, advertising, and basic site functionality. We categorize cookies into three groups:
- Essential cookies — required for the website to function properly (for example, security cookies set by our hosting provider and WordPress).
- Analytics cookies — help us understand how visitors use the site (Google Analytics).
- Advertising cookies — used by ad networks to deliver relevant ads and track ad performance (Google AdSense and affiliate partners).
You can manage your cookie preferences at any time through your browser settings or by using our cookie consent banner. For a detailed list of the specific cookies used on this site, please see our Cookie Policy.
Data Retention
We retain different types of data for different periods:
- Contact form messages — retained for up to 12 months after your inquiry has been resolved, then deleted.
- Email subscriber data — retained until you unsubscribe. You can unsubscribe at any time using the link in any email we send.
- Analytics data — retained for 14 months in Google Analytics (the default retention period with anonymization enabled).
- Server logs — retained for up to 30 days by our hosting provider for security and troubleshooting purposes.
Tool usage data is not retained at all, as it is processed entirely in your browser.
Your Rights
Depending on your location, you may have certain rights regarding your personal data under applicable privacy laws, including the General Data Protection Regulation (GDPR) and the California Consumer Privacy Act (CCPA). These rights may include:
- Right of access — you can request a copy of the personal data we hold about you.
- Right to rectification — you can ask us to correct inaccurate personal data.
- Right to erasure — you can request that we delete your personal data (subject to certain legal exceptions).
- Right to restrict processing — you can ask us to limit how we use your data.
- Right to data portability — you can request your data in a structured, machine-readable format.
- Right to object — you can object to our processing of your data for certain purposes, including direct marketing.
- Right to opt out of sale — under the CCPA, you have the right to opt out of the “sale” of your personal information. We do not sell personal information as defined by the CCPA.
To exercise any of these rights, please contact us using the information in the Contact section below. We will respond to verifiable requests within 30 days (or within the timeframe required by applicable law).
Data Security
We take reasonable technical and organizational measures to protect the personal information we collect. These include:
- SSL/TLS encryption on all pages (HTTPS)
- WordPress security hardening through the Defender plugin
- Regular software updates for WordPress core, themes, and plugins
- Limited access to personal data (only site administrators)
- Spam protection on contact forms
No method of electronic transmission or storage is 100% secure. While we strive to protect your data, we cannot guarantee absolute security. If you become aware of a security vulnerability on our site, please contact us immediately.
Children’s Privacy
NetworkCheckr is not directed at children under the age of 13. We do not knowingly collect personal information from children under 13. If you are a parent or guardian and believe your child has provided us with personal information, please contact us and we will promptly delete it.
International Data Transfers
NetworkCheckr is operated from the United States. If you are visiting from outside the United States, please be aware that your data may be transferred to, stored in, and processed in the United States, where data protection laws may differ from those in your jurisdiction. By using this website, you consent to the transfer of your information to the United States.
Where required by applicable law (such as the GDPR), we rely on appropriate legal mechanisms for international data transfers, including standard contractual clauses used by our third-party service providers.

We may update this Privacy Policy from time to time to reflect changes in our practices, third-party services, or applicable laws. When we make material changes, we will update the “Last Updated” date at the top of this page. We encourage you to review this policy periodically. Your continued use of NetworkCheckr after any changes constitutes your acceptance of the updated policy.
