🔒 Never shown on any page, to anyone - not even Premium members. It's only ever sent by email, and only when you choose to share it with a mutual match from the Chat page.

Same privacy as contact phone above - never displayed, only shared by your own choice.

Off by default. Turning this on only ever lets someone call you if they've ALSO turned it on for themselves AND you've mutually matched with them - no phone number is exchanged, the call happens directly in the browser.
