Privacy — Large Language Murder.

This game has no accounts, asks for no names, and collects nothing. Out of the box it makes no network connection at all. If you choose to supply your own API key, the answers typed at the table are sent to Anthropic — labelled by seat number only — so the machine can play. Nothing is stored, and nothing survives the game.

Which app this policy covers

This page covers one app, and only one. Our other mobile games — which collect nothing and never open a network connection — are covered separately at privacy for our mobile games.

• Large Language Murder com.hauntedspacehotel.largelanguagemurder A pass-and-play party game for one device and a table of people. Not a children's title.

The short version

Everything in this game turns on one switch: whether you have given it an API key of your own. It ships without one and is complete without one.

What we collect

Nothing. There is no account, no sign-in, no profile, no advertising and no analytics. Specifically, this app does not ask for, access, collect, store or transmit to us:

• Email addresses, phone numbers or postal addresses
• Location of any kind, precise or approximate
• Contacts, calendar, photos, files, microphone or camera
• Advertising IDs, device identifiers or any other tracking identifier
• Usage analytics, gameplay telemetry, crash reporting of our own, heat maps or session recordings
• Cookies, web beacons or cross-app profiles

We operate no server for this game and receive nothing from it. There is nowhere for us to keep anything, which is a stronger promise than a policy about how carefully we would look after it.

What leaves the device, and exactly when

The game asks you to type your name once per game, for the card that says whose turn it is. That name stays on the device. It is not sent anywhere, in any mode, and this is structural rather than a policy we are keeping to — every seat that appears in a request to Anthropic is written by a piece of code that produces PLAYER THREE and cannot see the list of names at all.

If — and only if — you have supplied your own API key and switched the live model on, one request is made per round, direct from your device to Anthropic. It carries:

• The one-word prompt for the round.
• The answers, authors and votes from rounds already revealed to the table, so the machine can play like somebody who has been sitting there — with each seat named PLAYER ONE, PLAYER TWO and so on.
• In CORPORATE mode only: every human answer for the round in progress. That is the entire point of that mode — the machine reads the table before it writes — and the mode is chosen on the title screen, in front of everybody, before a game starts.

Nothing else goes with it. No name, no account, no device identifier, no advertising ID, no location, no contacts, and nothing that persists between games.

One honest caveat, and we would rather write it down than sound cleverer than we are. An answer is free text — up to six words of six letters, typed by a person. We do not attach a name to it and we never ask for one, but we cannot promise nobody will ever type something that identifies somebody at that table. What we can promise is what the app does with it: it goes to Anthropic to produce one line of text, we never see it, and neither of us keeps it.

The API key is yours

This app ships no API key of its own. If you want the machine to answer live, you create a key in your own Anthropic account and paste it into the game. It is written to the app's private storage on the device, it is sent to nobody but Anthropic, and it never reaches us. Usage is billed to your account, not ours — a game costs a few cents. Delete the key, or uninstall the app, and the live half stops; the game carries on working exactly as before.

Playing across more than one device

The game can also be played with everybody on their own phone, over your local network. One device hosts and the others find it on the same Wi-Fi. That traffic goes device to device: it does not leave your network, it does not pass through any server of ours — we run none — and it reaches no third party. It carries the seats, the answers and the votes for the game in progress, and nothing else.

What is kept on the device

Two files, in the app's own private storage, which no other app can read and neither of which is backed up to us:

• Your settings — five numbers: narrator voice on or off, live model on or off, which mode, how many machines, which deck of prompts. That is the entire file.
• Your API key, if you pasted one in.

There is no save game, no history, no scoreboard and no record of who played or what anybody wrote. The machine's memory of the evening lasts exactly as long as the game does. Uninstalling the app, or clearing its data in Android's settings, removes both files completely.

AI-generated content, declared on purpose

This game is about an artificial intelligence and a great deal of it was written by one. We are saying so deliberately, and it applies to the offline build as much as the online one:

• The prompt words are AI-generated.
• The answers the machine plays when it is not connected are AI-written, and they ship inside the app.
• The title lettering is cut from an AI-generated image.
• When you supply a key, the machine's answer for the round is written live.

Whatever the machine writes is held to the same rule every player is: one to six words, each at most six letters, letters only, checked by the game's own rules engine before it can reach the table. A reply that fails is thrown away and a pre-written line is used instead, so nothing you see on a card is unchecked model output.

Third parties

• Anthropic — and only if you supply your own API key. They process the request that produces the machine's answer, under Anthropic's privacy policy. With no key, no request is ever made.
• Google Play — for distribution. Google gives us aggregate, anonymised console statistics: install counts, ratings, anonymous crash reports. We cannot identify anyone from them and we have asked for nothing more.

There are no ad networks, no analytics providers, no social logins, no crash-reporting SDKs of ours and no cloud services in this app.

Permissions

The Android build declares two permissions, both normal — Android grants them without a prompt and neither gives access to anything about you:

• INTERNET — the one request to Anthropic, when you have supplied a key.
• CHANGE_WIFI_MULTICAST_STATE — so a phone can find the host on your own Wi-Fi when you play across devices.

The game requests no other permission at all. The narrator voice needs none: Android's text-to-speech runs on the device.

Children

This is not a children's title and is not in Google Play Families. It is intended for players aged 13 and over. It is a party game in which people write things and a language model writes things back, and unlike our other mobile games we are not going to claim it is suitable for a small child.

Third-party licences

This game is built on other people's work as well as ours. The notices that work is owed are listed on our third-party licences page, ship as a text file beside the desktop build, and are in the app itself under Settings → Notices.

Your rights

Data-protection law gives you the right to access, correct, export or delete the personal data a company holds about you. We hold none — there is no account and no server — so there is nothing on our side to access or delete. To remove what is on the device, delete the key in the app, or uninstall it, or clear its data in Android's settings. If you want to ask about any of this, write to us.

Changes to this policy

If this game ever changes what it does with data, we will update this page and the date at the top before that version ships, and we will say plainly what changed.
