Privacy Policy

Last updated: May 14, 2026

What data we collect

Domains you check. When you enter a domain name into the checker, we perform DNS lookups against that domain. We don't save your queries in any database. Domain names may appear in standard web server access logs (this is true of every website on the internet) and are deleted after 30 days.

Technical request data. Like all websites, our server automatically receives basic technical information with each visit: your IP address, the page you requested, your browser type and version, the referring URL, and the time of the request. We use this for diagnostics, security, and aggregate traffic analysis only.

Cookies and similar technologies. Three categories:

• Essential cookies — used to remember your cookie consent choices and other site preferences. Always active.
• Analytics cookies — set by Google Analytics 4 to understand how visitors use the site. Active only with your consent.
• Advertising cookies — set by Google AdSense to display ads and measure their performance. Active only with your consent.

You can change your consent choices at any time via the "Manage cookies" link in the footer.

Third parties

The following third parties may process your data when you visit MXHelper:

• Google Analytics — aggregate traffic analytics. Subject to Google's Privacy Policy.
• Google AdSense — displays advertisements. Subject to the same Google policy.
• Cloudflare — provides DNS, CDN, and DDoS protection for the site. May log IP addresses for security purposes. See Cloudflare's Privacy Policy.

We don't sell or share your personal information with anyone beyond what's described above.

Your rights

Depending on where you live, you may have the right to:

• Access the personal data we hold about you
• Correct inaccurate data
• Request deletion of your data
• Object to or restrict certain types of processing
• Withdraw consent for analytics and advertising cookies at any time
• Lodge a complaint with your local data protection authority

These rights are guaranteed under regulations like the General Data Protection Regulation (GDPR) in the European Economic Area, the California Consumer Privacy Act (CCPA), and similar laws elsewhere.

Because MXHelper has no user accounts, most personal data is limited to short-lived server logs and cookies set by third parties. To exercise your rights regarding cookies set by Google, you can also use Google's own controls at myaccount.google.com/data-and-privacy.

Data retention

Web server access logs are retained for 30 days and then automatically deleted. We don't keep any other records of visits or diagnostic queries.

Children

MXHelper is a technical tool intended for adults managing domains and email infrastructure. We don't knowingly collect personal information from children under 13 (or under 16 in the EEA).

Updates to this policy

We may update this policy from time to time. The "Last updated" date at the top will reflect the most recent change. For material changes, we'll add a notice on the home page.
