Mark is a small utility. There is no ticket portal and no upload form, on purpose — a form that accepted your QR payload would break the privacy promise.

Operator: Ultimatum

Email: ultaultimatum@gmail.com

What to include

  • The page URL (for example /wifi or /how-to).
  • Browser and OS (Safari on iOS 18, Chrome on Android, and so on).
  • What you expected and what you saw. A screenshot of the preview helps; a password does not.

What not to send

Do not email WiFi passwords, full vCards, passport scans or logo files that contain secrets. We will not generate a code for you from an inbox, and mail is not a private encoder. Use the generator in the browser, then delete the message if you already sent one.

We do not accept files for processing at this address. There is no SLA. If the message is about a custom product or a paid website, say that clearly — that work is separate from this free tool.
