The Jefferson Line program needs JavaScript to load your day. Nothing here works without it — there is no tracking to escape by turning it off.
What this is: a private day sheet shared by one family and the friends they invite. You open it and see today: what you have committed to, anything waiting on your answer, and — filling whatever room is left — things happening nearby that the app found overnight.
What it is for: so people who want to do something together can find that out without a group chat. You say what you are doing; other people see it. That is the whole mechanism.
What it is not: a social network, a chat app, or a calendar that guesses when you are free. There is no feed, no likes, no followers, and nobody can see how often you open it. A blank day is yours; the app never fills it, counts it, or nags about it.
How a day works: one date at a time, split into Morning, Afternoon and Evening. “Add to the program” puts something on it — Committed if people should see it, Interested if it is a private note to yourself. “Mark me Out” blocks off time, and there is deliberately nowhere to say why.
Read how all of it works — the full guide, including what other people can and cannot see about you.
On iPhone and iPad the home-screen app keeps its own sign-in, separate from Safari, so a freshly installed copy may open signed out. That is how the system works rather than a fault here. Settings → “Link another device” gives you a code to sign it in.
Cruises, parties, cabins, proposals, what other people can see, getting a new phone signed in, and every word this app borrowed from ships. Open the full guide — it is part of the app, so it works with no signal.
Copy the diagnostic below into a message to the Director — it says what your device is, never what you've planned.

“Out” is complete on its own — no reason is asked, stored, or shown.
