DUO

One long conversation instead of a profile: DUO asks what you want, what you learned from past relationships and what your deal-breakers are, then says it models compatibility across hundreds of dimensions and texts you matches when both sides fit. No app, no swiping, free to join.

The absence is the whole of it. There is no privacy policy at any of the usual paths, no terms, no company name and no address anywhere on the site. For a product whose input is somebody's attachment style, their past relationships and their deal-breakers, and whose output is handing that person's details to a stranger, this is the emptiest set of rows in the directory relative to what the product handles.

Two smaller notes. Its number sits in area code 645, one of the newest overlays in New York, and the button on its own site puts an ampersand where the question mark belongs, which is malformed under RFC 5724: the standard opens the field list with a question mark, so without it the message text sits inside the recipient. Apple has historically been lenient about this and nothing else is. We record the number and not the link.
