How this works

This is the whole manual. It is part of the app, so it works with no signal. Nothing here is required reading — the app is meant to make sense without it. If you needed this page to work something out, that is worth telling whoever sent you the invitation, because it means a screen needs fixing rather than explaining.

The short version

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.

It exists so that 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 entire mechanism.

It is not a social network and there is no feed to scroll, no likes, no followers, and no messaging. Nobody can see how often you open it. An empty day is just a day, and the app will never treat it as a problem to solve.

Words this app uses

The app borrows its vocabulary from ships, and the borrowing is not decoration — the words are arranged the way a shipping line actually is, and once you see the arrangement the rest of the app stops needing explanation.

The picture, in one go. A shipping line is not a ship. It is the company, and belonging to one means you are known to it, not that you are at sea. Most days you are simply at home living your own day. Now and then some of you sail together for a few days — that is a cruise — and while it is running the ship slides a program under each cabin door in the evening. Some of you go ashore together as a party. And whatever the ship is doing, the ports have their own things going on, which nobody aboard arranged.

Every word below sits somewhere in that picture.

The line, and who is on it

• The line — everyone who has been invited. Your family, their friends, and the friends you bring. Being on the line together is like holding tickets with the same company: it means you are known to each other’s world, and on its own it shows you nothing about anybody’s week.
• The manifest — the list of who is on the line. Only a Commodore sees the whole thing.
• Boarding pass — an invitation. A link or a short code, plus a phrase said out loud. One person hands it to another; the app has never sent one and never will.
• Sponsor — whoever handed you your boarding pass. It carries no authority over you and does exactly one thing: if you lose every device you are signed in on, they can get you back aboard.

Where you are

• Cabin — your household. Whoever you live with, or are staying with while you visit. The people you would tell about your day without thinking about it.
• Cruise — a named stretch of days a group of you are doing together: a reunion weekend, a trip, a holiday everyone is home for. You do not board anything. You have one life and one day sheet, and the cruise is the voyage those particular days belong to — a label, not a room you go into.
• Port — a town this line calls at. Ports are how the app tells a Blue Lake concert from a Folsom one; they are a fixed published list, never a distance from wherever you happen to be.
• Shore party — the group that goes ashore together. When a cruise splits and four of you go one way and three another, that is a shore party, and what it gets up to is its own business rather than the whole ship’s.

Time aboard

• Your day — the one screen the app is built around. One day at a time, no endless scroll.
• Watch — a part of the day. A ship divides the day into watches and so does this: Morning, Afternoon and Evening. Everything on your day sits in one of the three.
• Day N — while a cruise is running, each day is also labelled by how far into the voyage it is. Day 1, Day 2, and so on.

Things you say

These four are the whole of what a person can put on a day, and they differ only in who is being told what.

• Committed — you are doing this. The people who can see your day will see it.
• Interested — a private note to yourself. Nobody else ever sees it, not even as a number.
• Proposal — you asking named people to answer. The only one of the four that asks anything of anybody.
• Out — you are unavailable for a stretch of time. You never say why, because there is nowhere in the app to type why.

The ship’s program

On a real cruise a printed program appears under your door each evening — what is on tomorrow, and when the ship sails. This is that, and only a coordinator writes it.

• Program item — something happening that anyone on the cruise may join. An offer, not a summons.
• Fixture — a fact that needs no answer. “Leave at eight.” “Checkout is eleven.” It appears on everyone’s day and asks nothing of anyone, the way a sailing time is not a question.
• All aboard — the cruise word for the time everyone needs to be back. It is an ordinary fixture with the most useful name a group weekend has.

Jobs, not ranks

Both of these are things somebody is currently doing. Neither is a status, neither is permanent, and both can be handed to somebody else in a moment.

• Coordinator — whoever is keeping a cruise or a shore party organised. Their one extra power is writing the program.
• Commodore — whoever runs the line: they bring people aboard and can take that access away. On a real shipping line the commodore is the senior officer across the whole fleet rather than the master of one ship, which is the right shape. A Commodore cannot read anybody’s days.

Ashore

• Discovered — something happening nearby that the app found on a public calendar overnight. Nobody on the line typed it and nobody is inviting you; it is simply what the ports have on. See Discovered events.

Where the crew work

• The ship’s log — the record of what a Commodore did: who was invited, whose access was ended, which sources were wired. It is append-only and holds nobody’s plans.
• The Bridge — the Commodores’ console, on the home screen and in Settings. It is not there for anybody who is not a Commodore. Two things on it are pages rather than app screens — the Commodore’s manual and the sources console — and the Bridge hands you their address for a browser. Nothing on any of it browses anybody’s plans, because no such screen exists anywhere in the app.

Every marker you will see

Each of these is a symbol and its words, always together, so they read the same in grayscale and to a screen reader. Nothing in this app is told to you by colour alone.

• ● Committed — someone is doing this.
• ☆ Interested (only you see this) — your private bookmark.
• ✉ Proposal — a question waiting on your answer.
• ⚓ Program — published to a cruise or shore party by its coordinator.
• ▪ Fixture — a stated fact about a cruise. Nothing to answer.
• ⊕ Open invitation — anyone who can see it may join.
• ● Joined — you joined this one.
• — Declined — you answered no. A complete answer.
• ✕ Out — unavailable for this stretch of time.
• ◇ Discovered — found on a public calendar overnight. Nobody typed it and it is not yours until you say so.
• ○ Free — the source published this as free to attend.
• ⚑ Holiday — a federal holiday falls on this day, which is why the weekend it belongs to is longer than two days.
• ⚐ Port of call — the town this event is in. When it says “the source’s usual one”, the publisher did not name a town and the app has filed it where that source normally publishes from, which is the weakest of the three ways it works this out and the only one that can be wrong for a touring show.
• ◈ Listed by more than one source — two or more places published the same event. It is shown once, and the badge says how many, so a listing you know about never looks missing.
• ⚠ Not seen at the source last night — this was listed before and was not listed last night. It has not been deleted, because if you were going you need to know.
• ✕ Cancelled at the source — whoever published it has marked it cancelled.

Home

The app opens on Home. It is a set of tiles: today, this weekend, looking ahead, who is around, cruises and cabins. Today's tile says how much is on, so most days you can see whether to open it without opening it.

The house button in the bar at the top goes back to Home from anywhere, and that bar never scrolls away. Everything else used to sit in a row of buttons at the bottom of your day, underneath the things the app found nearby — and there is no limit on how many of those there can be.

Your day

The day screen shows one date. The arrows at the top move a day back or forward. Under them, the day is split into Morning, Afternoon and Evening, and each of those lists what is happening.

It fits one screen. When there is more than fits, your own commitments and anything waiting on your answer are never the things that get cut — the discovered events are.

Under the title bar you will see something like “synced 2 min ago · program generated 2 September”. Those are two different clocks, kept not merged:

• Synced is the family’s own coordination, and it is live. When somebody commits to something, you see it on your next refresh.
• Program generated is the discovered events, and they are from last night. They are never live, and the app says so rather than pretending otherwise.

If you are somewhere with no signal, the app still opens and still shows the day. Anything you add is kept on your phone and sent the moment you have signal again — you do not have to remember to do anything.

Putting something on your day

“Add to my day” asks what kind of entry it is. There are four, and the difference between them is entirely about who is being told what.

• Committed — you are doing it. Anyone who can see your day sees it. Use this for almost everything.
• Interested — a private note to yourself. It appears on your day, marked so you know it is private, and it is never sent to anybody in any form. Use it for “maybe”, or for something you do not want to announce yet.
• Proposal — you are asking named people to answer. Use it when you actually need to know who is in. See below.
• Program item — only for cruise or shore party coordinators. It publishes to everyone on that cruise, and anyone can join it.

When you add something Committed, there is a tick box for open invitation. Tick it and anyone who can see the item can join in. Leave it and the item is just a statement of what you are doing.

Anything you added, you can remove. Removing shows an undo for a moment rather than asking “are you sure” first — the app’s general habit is to let you act and then take it back, instead of making you confirm everything.

Saying you are out

“Mark me Out” blocks off time when you are not available. It takes a start and an end, and that is all it takes.

There is no reason field. Not hidden, not optional — the place to type a reason does not exist anywhere in the app or in the database behind it. “Out” is a complete answer on its own, and nobody can ask the app what you were doing because the app does not know.

Being Out also answers proposals for you. If somebody proposes something inside a window you are Out for, you are already marked as unavailable and you will not be asked again.

If you set one by mistake, “I’m not Out after all” on your day takes it straight back off.

Proposals

A proposal is the app’s way of asking a specific set of people a specific question, once, without a group chat.

When you make one, you pick who it is for. Only those people see it. It appears on their day the next time they open the app — it does not notify anyone. Nobody’s phone buzzes because you had an idea.

You can set a decide by time. If you leave it blank, it is the start of the event itself. That deadline is the one thing in a proposal that can eventually send a reminder.

When you receive one, you have three answers: Commit, Interested, or Decline. All three are complete answers, and declining is not a lesser one — it closes the question and you are not asked again. There is no counter anywhere showing how often you decline things.

What other people can see about you

This is the question most worth having a straight answer to, so here it is in one place.

Being on the line with someone shows them nothing. That is the part most people assume wrongly, and the metaphor is exactly right about it: two people holding tickets with the same shipping line are not on a voyage together, and have no idea what the other is doing this week. Sharing the app with somebody does not let them see your days. What lets them see anything is sharing a cabin, a cruise, or a shore party with you — and nothing else does.

So the people who can see something of yours are exactly:

• Your cabin — whoever you live with sees the things you marked Committed that are not tagged to any cruise.
• A cruise you are both on — they see the things you tagged with that cruise, and the cruise’s own program.
• A shore party you are both in — they see that shore party’s things. The rest of the cruise does not see into a party.
• Anyone you named on a proposal — they see that one proposal, because you addressed it to them.

Everyone else sees nothing. Not a stripped-down version, not a busy/free bar — nothing. They do not appear in your list of people and you do not appear in theirs, and “Who’s around” only ever lists people who share one of those three things with you.

This is why a friend you bring aboard does not end up looking at your family’s week, and your family does not end up looking at your friend’s. You are on the same line; you are not in the same cabin. If you want a friend to see something, you put them on a cruise or a shore party with you — that is the act of showing.

What they see, when they can see:

• Your name, as it appears on the invitation you redeemed.
• Things you marked Committed, and program items you joined.
• That you are Out for a stretch of time — the times, and nothing else.
• Your answers to proposals you were included in.

Nobody can see, ever:

• Anything you marked Interested. Not the item, not that one exists, not a count of them.
• Why you are Out. There is no such information anywhere.
• When you last opened the app, how often, or from where.
• Anything you typed and did not save.
• That you blocked them, if you blocked them.

It is worked out fresh every time, not stored. Leave a cruise and the people on it stop seeing your things immediately — there is no permission to go and revoke, because there was never a permission. The app just stops finding a reason to show them.

The Commodore can invite people, take somebody’s access away, sign a single lost device out, and see a log of those actions. The Commodore cannot read your plans; there is no screen anywhere in the app that shows one person another person’s day in full, and being Commodore does not put anyone in your cabin.

The operator — whoever runs the server — can read the database directly, the same as with any app that stores anything. That is stated plainly rather than glossed over. This is privacy sized for keeping acquaintances out of each other’s plans. It is not a security model, and you should not put anything in here that would hurt you if it got out.

Cruises

A cruise is a named stretch of days that a group of people are doing together — a reunion weekend, a trip, a holiday everyone is home for.

You do not board anything. This is the one idea worth getting, and it is where the metaphor stops being a picture and starts being the design. A cruise does not move you onto a separate ship, into a separate app, or out of your own life. You have one day sheet and you always did; the cruise is the voyage those particular days belong to.

So turning the cruise on is not going somewhere. It is the ship’s program appearing alongside your own day — the dentist on Tuesday is still on Tuesday, with the departure time sitting next to it. Turn it off and nothing has moved; you are just looking at the same days without the voyage’s label on them.

That is also why deleting a cruise takes nothing away from anybody. There was never a container holding people’s plans, so there is nothing to empty.

On a cruise you can:

• See who is on it.
• Invite someone aboard — you get a link and a phrase to hand them yourself.
• Form a shore party, if a few of you are splitting off.
• Leave, whenever you like, without asking anyone.

If you are the coordinator you can also set fixtures, publish program items, and make somebody else a coordinator too. It is a shared job rather than a baton: adding another does not remove you, and a cruise can have as many as it needs. There is a short guide to it — Running a cruise — covering which of the four tools to reach for.

If a coordinator leaves, the cruise says so — it shows as having nobody coordinating it, and anyone on it can take the job. Nothing gets stuck.

Nobody can remove anybody. There is no button for it, because there is no such capability in the app at all. People join and people leave; nobody is thrown out.

Deleting a cruise removes the label and its fixtures. It does not delete anyone’s plans — everything people put on their own days stays on their own days, just without the cruise label.

Cabin, cruise or shore party — which one do I want?

Three of the words in this app name groups of people, and they are not interchangeable. The short answer is that they are told apart by how long they last, not by how many people are in them.

• A cabin is standing. It is who you live with. It does not belong to a trip and it does not end when one does. You change cabins when you move house, or when you are staying somewhere else for a while — not when the plan changes.
• A cruise has a start and an end. It is a named stretch of days a group of you are doing together, and it stops existing when those days are over. Make one when several people need to be looking at the same days.
• A shore party lives inside a cruise. It is the group that splits off to do one thing while everyone else does another — what a cruise line would call a shore excursion group. It cannot outlast the cruise it belongs to, and the rest of the cruise cannot see into it.

Walk it in that order and you will land in the right place:

1. Do these people live with you, or are you staying with them? Cabin.
2. Is this a run of days a group needs to see together? Cruise.
3. Are some of the people already on a cruise going off to do their own thing? Party.
4. None of the above? Then it is not a group at all — it is just something you are doing, and it goes on your day. Most things are this. Making a group for an afternoon is the commonest way to make this app harder than it is.

The one that catches people is the difference between a cabin and a party. Both are small and both are people you know well. A cabin is where you sleep; a shore party is where you are going. Four people who live together and are also going to the coast on Saturday are a cabin and a shore party, and the app expects exactly that.

Shore parties

A shore party is a smaller group inside a cruise: the people who go off and do one thing while the rest do another. What a shore party does is its own business — the rest of the ship does not see into it — which is the whole reason to form one rather than putting everything on the main program.

Anyone on the cruise can form one. Whoever forms it coordinates it, which gates exactly one thing — publishing program items to that shore party — and can be handed over. If the person who formed it leaves, the shore party says it has nobody coordinating it and anyone in it can take it on.

Cabins

A cabin is your household: whoever you live with, or are staying with while you are visiting. It is who sees your committed days without being invited to anything.

You were given one when you came aboard. A line does not walk somebody up the gangway and leave them to find their own berth, so the app assigns a cabin the moment you board and names it after you. Two things are worth doing once, on the Cabins screen:

• Say where home is, if you want to. It is a label — a name for where this cabin is, seen only by the people in it. This app works out no distances and no travel times. Several screens said it did, for months, and none of it was ever true.
• Rename it, if the name is wrong. “The Smiths” reads better than your own name once there are four of you in it.

You invite the people you live with into it, and you can leave whenever you want. As with cruises, nobody can remove anyone else. Leaving your last cabin does not put you ashore — you move into one of your own, because nobody is aboard without a cabin.

Changing cabins is ordinary and it is not a big deal. Move in with somebody, move back out, be in two at once while you are staying somewhere for a month — all of it is allowed and none of it needs anybody's permission. Nothing you have put on your days is attached to a cabin, so changing one never moves, deletes or hides anything you own. It changes only who sees the days you have marked committed from here on.

Who is around

“Who’s around” shows a day at a glance for the people on the line. Each person shows in one of three states, and each state is a word and a symbol, not just a colour, so it reads the same for everyone:

• ● Committed — they have said they are doing something.
• ✕ Out — they have marked themselves unavailable.
• ? No info — they have not said anything. This is not “free”. It means exactly what it says.

“No info” and “Out” are different, and the app never guesses that silence means availability. If you want to know, ask.

You show on your own row as ∘ Available (your day is yours), which is the app declining to grade your own day back at you.

Discovered events

Overnight the app reads a handful of public event calendars from around the area and puts what it finds on the relevant days, marked ◇ Discovered. This is what the ports have on. Nobody on the line typed any of it and nobody is inviting you — it is simply what is happening nearby, put where you would see it.

Each one gives you two buttons:

• Put it on my day — makes it yours, Committed, visible to people who can see your day.
• Keep it to myself — makes it yours, private, seen by nobody.

Until you press one of those, the event is not yours in any sense and nothing about you has been recorded against it.

Two honest warnings. Discovered events are only as good as the sites they came from, so check the details before you drive anywhere — the “Details at the source” link goes to whoever published it. And an event the source has stopped listing does not vanish; it stays, marked ⚠ not seen at the source last night, because if you were going to it you need to know that rather than find an empty car park.

Coverage is incomplete. The app is not trying to list everything, and a gap is not a bug.

This weekend

This weekend on your day sheet answers the question people actually ask each other, which is not “what is on Saturday” but “what is on this weekend”. It shows every day of it at once, with your own plans, anything your cruise has fixed, and what the app found — the same things the day sheet shows, over more than one day.

The weekend here is Friday and Saturday. That is this family's weekend rather than the conventional one, and the app does not argue with it.

It gets longer when a holiday says it should. The app knows the eleven federal holidays and, more usefully, knows the day each one is actually taken — Independence Day on a Saturday is taken on the Friday before, and the Friday is when somebody is free. When a holiday sits beside the weekend, the view stretches to cover the whole run: a Monday holiday makes it Friday to Monday, and the screen says which holiday did that rather than just quietly showing a different number of days.

It stretches by one day of bridging and no more, so two separate weekends never merge into a nine-day one that nobody would plan around.

Free things only

The Free things only button keeps what the publisher itself called free. It does not keep events with no price on them: a listing that said nothing about money is a listing that said nothing, and putting it under “free” is how somebody ends up at a ticket desk they were told not to expect. When the filter takes things away, the screen says how many.

Your chosen ports apply here exactly as they do on a day.

Looking ahead, and planning

Look ahead on your day sheet is for the question the weekend view cannot answer: what is on over a particular stretch of days, weeks from now. Pick a day, or a start and an end, and it shows you — no stepping forward one day at a time, and no need to invent a cruise just to have something to look at.

It shows the days that have something on them and skips the ones that do not, because a two-month range rendered as sixty empty headings is a worse answer than a short list. Your ports and the free filter both apply.

What it will not tell you is anything about anybody else. It shows what the app found, your own days, and anything your cruises have fixed. It does not show who is free, who is out, or what anyone else is interested in — not on this screen and not on any screen. Being able to sweep weeks of time looking for a person is exactly the thing this app is built not to have, and a planning view does not become that by having dates in it.

Two months is the most it will show at once. Past that it says so, with the number, rather than quietly showing you less than you asked for.

The scannable squares, and what they can and cannot do

An invitation and a device-link code both come with a square you can point a camera at. It carries a web address rather than the bare code, because a camera reads bare characters perfectly and then offers to search the web for them, which is no use to anybody.

On iPhone and iPad a scanned address always opens Safari, never the app on your home screen. That is the phone, not this app, and there is no way round it — Android opens the installed app, iPhone and iPad do not. It matters because the installed app keeps its own sign-in, separate from Safari.

So Safari is used as the courier rather than the destination. Whichever square you scan, the page it opens has one job: it shows your code, copies it when you press the button, and tells you where to paste it. Then you open the app on your home screen and paste. Nothing is signed in from the browser unless you are on a computer, where nothing is separated anyway.

If the copy button does nothing — some settings refuse it — press and hold the code and choose Copy. It sits in a field for exactly that reason, and it is short enough to type if it comes to that.

The written code is the half that always works. The square is a convenience on top of it and never a replacement for it.

Cruises the app offers

Some stretches are worth planning around before anybody notices them. Thanksgiving is three days this year; Labor Day weekend is four. The app knows that, so rather than everybody separately working it out, it says so — an offer on the weekend and look-ahead screens, with the dates and the reason.

Pressing Make it a cruise makes an ordinary cruise, exactly as if you had typed it in, and then it is yours: name it something else, invite whoever is coming, set fixtures. Ignoring every offer forever costs nothing and nothing nags. If a cruise already covers a stretch, the offer says which one instead of suggesting you make a second.

Offers come from two places. The eleven federal holidays, worked out rather than listed, so the app knows the day each is actually taken. And Cal Poly Humboldt's approved academic calendar — fall break, spring break, finals and commencement weeks, the gap between semesters — because those are the dates a good deal of this county plans around whether or not anybody in it is a student. Cesar Chavez Day is in there too: it is a California holiday, so the federal list cannot know about it, and the campus is shut.

Where a campus break and a federal holiday are the same week away, you get one offer and not two — the campus one, because it is the longer stretch and the reason anybody is free.

Move-in and move-out are not in it. The university's calendar does not carry them; Housing publishes residence dates separately, and the nearest thing in the academic calendar is an advising and orientation week, which is not the same claim. A date invented from an adjacent one is worse than a date that is missing, because it looks like knowledge.

A stretch too long to be one cruise — the three weeks between semesters — is shown but not offered. It is worth knowing about and it is not a trip.

Ports of call

A line calls at a fixed list of places. Yours are Eureka, Arcata and Blue Lake on the north coast; Folsom, El Dorado Hills, Placerville, Shingle Springs and Orangevale along US-50; and Brooks, which is off the corridor and there on purpose.

Tick the ones you want on the Ports screen and events at the others stop appearing on your days. It is per device, so the same person can have different ports on a phone and on a tablet, which is what happens when one of them lives in a bag that travels.

This is not a map, a search, or a “near me”. The app never asks where you are, never receives it, and never stores it. What it sends when you have chosen ports is a list of port names — the same list for everybody who picks the same towns. That is the whole reason it is a fixed published list and not a distance: a radius is a question about you, and a port is a fact about the event.

Three things worth knowing about how an event gets its port:

• Most of the time the publisher names the town, and that is what you see.
• Sometimes the town is only in the street address, and the app reads it out of there.
• When neither is true, the event is filed where that source usually publishes from, and the badge says so. A university listing that names only a building is filed at the town the campus is in — right nearly always, and wrong for a touring production that went somewhere else.

An event in a town this line does not call at — the Folsom chamber lists some — is shown when you have chosen no ports, and not shown when you have. Whenever your choice removes anything, the day says how many, so a quiet day is never quietly a filtered one.

Where you are, day by day

Your chosen ports are a standing answer to what am I usually interested in. This answers a different question: where will I actually be on the 14th.

Every day, on the day sheet and on both the weekend and look-ahead screens, has a Where you are on this day chooser. Open it, tick every town you will be near that day, and press Save this day — that day then shows what is on at all of them, whatever your standing ports say. Press Show anywhere to go back to your standing ports; on a day inside a cruise the same button says Follow the cruise, because that is what going back means there.

Tick more than one. Coming home is usually being near several towns at once rather than in one of them, and a day that held a single port made you choose which of your towns counted. Saving replaces what was there, so the same control that adds a town takes one away.

This is what a cruise actually looks like. One person drives up on the Friday, is with everybody on the Saturday and Sunday, and spends the Monday at a partner's family in another town. One standing setting cannot describe that, and stepping through four days changing a setting each time is a chore rather than a plan — so the choosers sit on the screen where you are already looking at those four days in a row.

A day you have said something about always gets a row on the look-ahead screen, even when nothing is on there. Nothing on in Folsom that Saturday is an answer, and usually most of why somebody looked.

A cruise has one too

A cruise can say which port it is at, day by day — its itinerary, which is the thing a real line prints. A coordinator sets it on the cruise screen, and it works in three steps:

• A day the itinerary names — everybody aboard sees what is on there that day.
• A day it does not — the cruise's usual towns apply, if it has any. A cruise can name several, for the same reason a day can.
• Your own answer beats both. Say where you will be on a day and that day is yours, whatever the cruise says. It replaces the cruise's answer rather than adding to it — otherwise the towns you said you would not be in would come back onto your own screen. It changes nothing for anybody else and does not touch the cruise's itinerary.

That is the Friday-to-Monday case in one place: the cruise is in Eureka all weekend, you set the Friday to Arcata because you are driving up, and the Monday to wherever you are going afterwards. Three presses, on the screen already showing you those four days.

Every day says where its answer came from — from the itinerary, where the cruise usually is, or your own. A screen that filters itself down to one town without saying why is how an app comes to look empty.

A port is not the base. The base is what you call the place you are staying — “The Mountain House” — and it is a label for people to read. The port is which town this line calls at, and it is what events are filed under. A cruise wants both, and they are set separately for that reason.

Nobody else sees where YOU said you would be. Your own answer is private in the same way an Interested bookmark is: it exists so you can see what is on where you are going, and there is no screen anywhere that shows one person where another person will be. A cruise's itinerary is different and is meant to be shared — it is published to everybody aboard, because that is what an itinerary is for.

Blocking someone

Blocking is in Settings. It works both ways at once: you stop seeing them and they stop seeing you, everywhere in the app.

They are never told. There is no notification, no marker on their screen, and no way for them to find out from the app. You can unblock whenever you like.

Your own calendar app

Settings gives you a calendar feed link. Paste it into Apple Calendar, Google Calendar or anything else that takes a subscription, and your things from here show up alongside the rest of your life.

Treat that link like a key: anyone who has it can read that feed. If you ever paste it somewhere you regret, you can get a fresh one, which turns the old one off.

Your devices, and getting back in

There are no passwords here. Your device holds a key instead, which is why you never had to make an account.

Each signed-in device has a name you chose, so you can tell them apart. In Settings you can see them all and sign any one of them out on its own — if you lose your phone, you sign out that phone and nothing else.

To add a device — a new phone, a laptop, or the installed app — open Settings on a device that is already signed in, choose “Add another device”, and you get a short code. Type that code into the new one. Codes are single use and expire, so get a fresh one each time.

If the installed app opens signed out — this catches everybody once on iPhone and iPad. The app on your home screen keeps its own sign-in, completely separate from Safari, so installing it after joining means opening a copy that has never seen your key. That is how iOS works, not a fault. Open the app in Safari, go to Settings, get a link code, and type it into the installed one.

If you have no signed-in device at all — a lost phone, a cleared browser — nothing can be emailed or reset, because there is no email address and no password. Somebody has to let you back in, and it takes them about a minute.

Ask whoever invited you first. They can issue you a code themselves, from Settings on their own phone, without finding anyone else. If you cannot reach them, any Commodore can do the same.

What they give you is a code and a phrase said out loud. Enter both on the sign-in screen and you are back in as yourself — your days, your cruises and your cabin exactly as you left them. It does not make a second account, and it does not take up another seat.

The app itself has a page for this at Locked out, reachable from the sign-in screen. It explains all of the above and lets you leave a note if you genuinely cannot reach anybody. Be clear-eyed about what that note does: nobody is alerted, because this app cannot send messages to anyone. It puts a line on a screen a Commodore will see next time they look. Talking to a person is faster.

Bringing somebody aboard, and helping them back

Whoever hands you an invitation is your sponsor, and whoever you hand one to is yours. It is not a rank and it carries no authority over anybody — it does exactly one thing.

If somebody you brought aboard loses every device they are signed in on, you can get them back in. Settings, “People you brought aboard”, and the button beside their name. You invent a phrase, say it to them, and read them the code. You do not need to find a Commodore, which matters at the moment it is needed, because that is usually a weekend.

It is narrow. You can only do this for people whose invitation you actually minted. You cannot do it for anybody else, and asking about somebody you did not sponsor gets the same answer as asking about a person who does not exist — so it cannot be used to find out who is on the line.

Bringing a friend in

Whether you can invite people depends on how the line is set — sometimes only Commodores can, sometimes coordinators too. If you can, the app gives you two things: a link, and a phrase.

The app sends nothing. It does not email, text, or message anyone, ever. You hand the link and the phrase over yourself, the way you would give someone an address, so nobody arrives here without a real person having actually decided to bring them.

The phrase is separate from the link, so a link seen over somebody’s shoulder is not enough on its own. Say it out loud rather than sending it in the same message.

Invitations expire if they are not used, and a seat that expires frees up again.

When something is wrong

If a discovered event is wrong, it is wrong at the source — the app copied it faithfully. Tell whoever runs the line and the source can be fixed or dropped.

If the app itself is broken, open ⓘ at the top of the screen and press Copy diagnostic report. That gives you a block of text describing your device, your browser, and which version of the app you are running. Send that rather than a screenshot — it carries the things a screenshot cannot show and none of the things you have planned. It contains nothing about your days.

If something about the app is hard to use — small text, poor contrast, anything that does not work with the tools you use — that counts as broken and is treated like any other fault. The privacy page has the address for reporting it.

Your data, and leaving

Settings has My data. It shows you everything the server holds about you and lets you download all of it, in a form you can actually read.

The same screen can delete it. What that does is exact: your things are removed, your keys stop working, and your name is replaced with “a former member” wherever it appeared in something you organised, so nobody else’s plans break. It cannot be undone.

Backups are a nightly snapshot that ages out within thirty days, so a deletion finishes clearing itself within a month. Whether any snapshot exists at all depends on the line being set up for it, and if it is not, the live database is the only copy — the privacy page says the same, and a Commodore can see which it is on the Bridge. That is worth knowing before you count on a backup being there.

Nothing you enter expires. That thirty days is how far back the backups go — it is not a shelf life on your plans. Put something in today for next summer and it will still be there next summer, along with the cruise it belongs to and everything anyone else put on it. Nothing in this app deletes a person's own entries on a timer; every deletion that exists anywhere is one a person pressed.

What this app will never do

These are not current limitations. They are decisions, and they are written down so that nobody has to wonder whether they might change.

• No notifications. Nothing in this app pushes anything to your phone today — not a proposal, not a reply, not a change to a day you are on. Two are the only ones that would ever be added: a decide-by deadline you were asked about, and a travel or weather warning on something already booked. Neither is built. Everything else is silent by decision, and that is not going to change.
• No chat. There is no messaging in here and there will not be. You already have somewhere to talk to each other.
• No streaks, no scores, no progress bars. Nothing counts how much you did or how much of a trip is left.
• No nagging about an empty day. Doing nothing is a valid way to spend a day and the app treats it as one.
• No guessing when you are free. The app will not read your gaps and suggest times. Silence means silence.
• No finding people or places by browsing. There is no directory, no map to explore, no discovery screen.
• No adverts, no tracking, no analytics. Nothing here is measuring you.
