What sharing contact does

The button is for one match that has already been revealed. You can take it back.
The short answer
Share my contact is a button on a revealed match. Your host invites friends. The host invites friends they'd love to have there. One private link per couple. The sheet says this goes only to this match, and that you can take it back anytime.
You add a phone, an email, or a handle. At least one is required. An email has to be a real email. After you share, the button says Edit contact, and Stop sharing takes it back.
Adult only. Private by design. You confirm you are 18 or older. The host still checks you in. A private no stays private.
What the email says
Email them a note starts checked. The subject is A match shared contact info. The note says a match shared contact info and to open the app. It uses the public-safe name, or Your event if that name is blank. It does not name who shared, and it does not include the phone, the email, or the handle.
That email sends the first time you share. Editing the details does not send it again. Unchecking the box skips it. Stop sharing does not send it. A test party does not send it.
The match sees what you shared, with Call, Text, Email, and Copy. The host is not copied on the email.
Who can use the button
The button is not there before the reveal. A one-sided yes does not get it. On a key party it is the Play Partner who was revealed, and the other people in a group match you are in. On a play party it is a mutual match after the host reveals. A couples-only play party shares with the couple.
On a speed date it shows after that night's matches are revealed. A speed date that is only the gathering before a key party does not share contact there. The app says contacts stay with the key party.
A night in Houston can use the button. Nashville can too. Those cities have their own pages. The contact still goes only to that match.
Sharing contact is not a new match
All mutual-yes matches are revealed by the format the host already chose. Sharing a phone does not create another yes. A one-sided yes stays hidden.
A key party shows one Play Partner at the same time, after the host starts the reveal. A play party keeps matches hidden until the host reveals them. A speed date is short rounds, then yes or no.
