Privacy Policy

1. Who We Are

NetworkCheck.net ("we," "us," or "our") provides free internet diagnostic tools including an internet speed test, IP address lookup, and website status checker. Our site is located at https://networkcheck.net.

2. Information We Do Not Collect

We do not collect, store, or process any of the following:

• Your name, email address, or any contact information
• Your IP address on our own servers (your IP is fetched directly by your browser from third-party APIs)
• Your internet speed test results
• Any URLs you check using the "Is It Down?" tool
• Payment or financial information of any kind

We have no user accounts, no login system, and no database of user information.

3. How Our Tools Work

Each tool on NetworkCheck.net operates entirely within your browser:

• Speed Test — measures your connection speed by downloading and uploading test data directly between your browser and Cloudflare's servers. We do not see or store your results.
• IP Address Lookup — your browser requests your IP information directly from a third-party geolocation API (ipinfo.io). We do not receive or log your IP address.
• Is It Down? — your browser queries Google's public DNS service to check whether a domain resolves. We do not log the domains you check.

4. Third-Party Services

Our tools rely on the following third-party services to function. Each has its own privacy policy:

• Cloudflare (speed test) — cloudflare.com/privacypolicy
• ipinfo.io (IP lookup) — ipinfo.io/privacy-policy
• Google DNS (site status check) — Google DNS Privacy Policy
• Netlify (site hosting) — netlify.com/privacy

These services may collect standard server log data such as IP addresses and request timestamps as part of their normal operations. We do not control or have access to this data.

5. Advertising

NetworkCheck.net displays advertisements served by Google AdSense. Google uses cookies to serve ads based on your prior visits to this and other websites. You can opt out of personalized advertising by visiting Google's Ads Settings.

For more information on how Google uses data when you use our site, visit: How Google uses information from sites that use our services.

6. Cookies

NetworkCheck.net itself does not set any cookies. However, Google AdSense may set cookies on your device to serve relevant advertisements. The "Is It Down?" tool uses your browser's localStorage to store a brief history of recently checked sites. This data stays on your device and is never transmitted to us.

7. Children's Privacy

NetworkCheck.net is not directed at children under the age of 13. We do not knowingly collect any personal information from children. If you believe a child has provided personal information through our site, please contact us and we will take steps to remove it.

8. Changes to This Policy

We may update this privacy policy from time to time. Any changes will be posted on this page with an updated effective date. Continued use of the site after changes constitutes acceptance of the revised policy.
