Privacy Policy

Last updated: 10 October 2026. This policy applies to https://dnschecker.sd9.in.

Data we process

Lookups send the hostname or IP you type to the origin PHP resolver and, if needed, to public DNS over HTTPS services (Cloudflare, Google, NextDNS). Those queries are required to return DNS answers.

What we do not do

• No user accounts or marketing lists.
• No advertising pixels or third-party analytics tags in page templates.
• No sale of query logs.

Infrastructure logs

Hostinger and Cloudflare may store standard request logs such as IP address, user agent, URL, and timestamp for security, abuse control, and reliability. Retention follows those providers.

Cookies

The application does not set first-party tracking cookies. Cloudflare may set a security cookie when a challenge is required.
