When a lookup is run, the service may process the domain name, optional DKIM selector, selected lookup source, request ID, IP address, user agent, timing information, and diagnostic results. This information is used to perform the check, troubleshoot errors, protect the service, and produce operational lookup reports.
If you send a message, we process the details you provide, such as your name, email address, optional domain, optional DKIM selector, and message content, together with technical request data. Contact submissions may be stored for follow-up and sent using the AuthSMTP email service.
Forms are protected with Cloudflare Turnstile and rate limiting. Cloudflare may process technical request data as part of deciding whether a request appears legitimate. The site does not intentionally use marketing analytics or advertising tracking.
Form submissions are checked using Cloudflare Turnstile for spam prevention, and contact form submissions are processed using the AuthSMTP email service provider. Those providers may process technical request data as part of delivering, protecting, and securing the service.
Operational logs and submissions are kept for as long as reasonably needed to operate, secure, debug, and improve the service. Information is not sold. It may be shared with service providers that help deliver, secure, host, or email the service, or where required to investigate abuse or comply with legal obligations.
