A name, phone number, email address, and (optionally) LinkedIn or Instagram links, plus your profile photo if you have one set. This is separate from your emergency contacts , it’s your own contact details, offered as a convenience.
Turning it on
This is switched off by default. Turn it on in your account settings and fill in the details you want included , you don’t have to include all of them.
What a finder sees
