Privacy Policy
Last updated: June 9, 2026
This Privacy Policy explains how OpsCheck handles information submitted to its DNS, SSL, email and network diagnostic tools.
Diagnostic inputs
Depending on the selected tool, users may submit domain names, IP addresses, hostnames, URLs, email or domain authentication records, HTTP headers and other diagnostic inputs. These inputs are used to run the requested check and display the result.
Technical logs
The server may keep technical logs such as request metadata, timestamps, IP addresses, user agent information, errors and security events. These logs may be used for security, debugging, abuse prevention, reliability and service maintenance.
External lookup services
Certain tools may query external DNS, WHOIS, blacklist, SSL, SMTP or network-related infrastructure depending on the selected check. Results may therefore depend on third-party availability, policies, cache state and rate limits.
