Nobody, until you decide otherwise. Privacy works per item, not per trip, so you can share a journey and keep one side-trip out of it. Share links are private and revocable.
Any trip becomes a private link: live while you're travelling, a keepsake once you're home, in the language of whoever you send it to.
Link Claude, or any MCP client, with a read-only token and ask it about your own travel — where you've been, what to book next, how to hold on to status.
Usually within a day or two. Pelgrim is in alpha, so bug reports are genuinely useful rather than merely tolerated.
