If you've spotted converse.tt.omtrdc.net in your browser's network log, you're looking at a technical backend server, not a public website. Based on the signals we have, this is almost certainly part of Adobe's advertising and analytics infrastructure (Adobe uses the 'jag' server and the omtrdc.net domain for its tracking services).
For this type of service, the lack of contact info, about page, and legal documents is normal—they belong on the parent domain. What matters here are the technical fundamentals: a valid SSL certificate, modern TLS, fast response times, and hosting on Amazon Web Services. The domain has been observed in the Wayback archive for two years, has never appeared on any blacklist, and Google's Safe Browsing reports no threats.
If you're concerned about privacy, this endpoint is likely used by a site you visited that employs Adobe Analytics. That's standard practice across the web. There is no evidence that this subdomain itself is malicious. If you're a developer or security researcher, you can confidently treat this as a legitimate tracking server.
