MailAuth.Tools is designed to minimize data collection. DNS lookup tools process the domain you submit so the server can query public DNS records. Email Header Analyzer runs in your browser and does not send pasted headers to the server.
The server may keep standard operational logs such as IP address, URL, timestamp, user agent, and error details for security, abuse prevention, and reliability. Do not paste secrets, private keys, credentials, customer data, or confidential messages into any online tool.
Affiliate links or analytics may be added later. If they are added, this policy should be updated before launch.
