Privacy policy

Last updated: 18 August 2026

NetCheck respects your privacy. This page explains clearly what happens to data when you use the site.

1. Data you enter

The domains, URLs or addresses you enter are used solely to run the network query you asked for (DNS, WHOIS, SSL…). Those queries are read-only and their results are neither stored nor linked to you.

2. Data we collect

No sign-up is required. We only use :

• anonymous traffic statistics — page viewed, time spent on it, device type, language and country. None of this uses a cookie or a third-party service : your IP address is only used to derive the country, then turned into a one-way daily fingerprint that changes every night — it is never stored. If your browser sends the “Do Not Track” or GPC signal, you are not counted at all ;
• local storage (your light/dark theme preference), which stays on your device.

3. Advertising and cookies

The site is funded by advertising (Google AdSense, for example). These partners may use cookies to serve relevant ads. You can manage personalised advertising in your Google ad settings. A consent banner lets you accept or refuse non-essential cookies (GDPR).

4. Your rights (GDPR)

Since we keep no personal data about you, there is nothing on our side to access or delete. For data handled by our advertising partners, please refer to their own policies.

5. Contact

For any question, write to us via the About & contact page.
