Privacy policy
Last updated 20 October 2026
Titans of the Line is a railroad-building game run by Zimmerman Works LLC (“we”). It has no accounts in the usual sense: no email address, no password, no profile. This page says everything the game keeps about you, why, and how to make it go away.
What we keep
| What | Why |
|---|---|
| A device key. A random number your phone makes the first time you start or join a game. We store only a one-way hash of it. | It is how the game knows which seat is yours. It is not linked to your name, phone number or any other account. |
| A recovery phrase. Six words kept on your phone until you tell us you have written them down. We store only a one-way hash. | So you can move your games to a new phone. |
| Your display name and the crayon colour you pick. | The other players at your table see them. |
| Your games: every move, the cards dealt, and the result. | The game is played on our server, and the record is what lets everyone see the board and the review. |
| Table talk: messages you type in a game’s chat. | The other players in that game read them. Each game keeps its most recent 200 messages; older ones are deleted. |
| Mutes and reports. Who you have muted, and any message you report (with the game and who said it). | So muted players stay muted, and so we can act on reports. |
| An age group: under 13, 13 and over, or “skipped” (the question not answered yet). Never your birth year. | It decides whether chat, notifications and a typed name are switched on. See below. |
| A push subscription, if you turn on turn notifications. | The address your phone’s browser gives us for sending “it’s your move”. Turning notifications off deletes it. |
Usage statistics. For players who said they are 13 or over, we use Vercel Web Analytics and Speed Insights to count page views and measure load times. They set no cookies, and they do not identify you or follow you to other sites. For the same players we also count four moments of play (starting a game, playing a turn, the guided first game’s first payday and how many seconds it took, and giving up a game before its first payday), noting only the kind of game, the board and the turn, never a name, a game code or anything you type. For a player under 13, or before the age question is answered, none of this is loaded or counted.
Server logs. Like any website, our host briefly logs requests, including your IP address, to run the service and stop abuse. We use IP addresses only to limit how fast one address can make requests.
What we don’t do
- We don’t sell or rent your information, or share it for advertising.
- We don’t show ads, and we don’t use tracking cookies or advertising IDs.
- We don’t ask for your email, phone number, location, contacts or photos.
Who else handles it
Only the services that run the game for us, under their own security commitments:
- Vercel hosts the app and its usage statistics.
- Upstash stores the game database.
- Your browser’s push service (Google, Apple or Mozilla, depending on your phone) delivers turn notifications, if you turn them on.
We may also disclose information if the law requires it.
Children
Titans of the Line is for everyone, including children. Before the first game it asks for a birth year and keeps only whether the player is under 13. The question can be skipped; a player who skips is treated exactly as a player under 13 until they answer it, which they can do once, in Settings. For a player under 13, or one who skipped:
- table talk is off: they cannot send messages and are not shown other players’ messages;
- turn notifications are off;
- usage statistics are off: the analytics scripts are never loaded and nothing is counted;
- they cannot type a name: other players see a railroad name we choose, like “Engineer Otter”;
- the game keeps only the device key, the recovery-phrase hash and the moves of their games, which it needs to run the game.
A parent or guardian can delete their child’s data at any time from Account in the app, or by writing to us. If you believe we hold information about a child under 13 beyond what is described here, contact us and we will delete it.
How long we keep it
Your account and games are kept until you delete them. Chat keeps only each game’s most recent 200 messages. Reports are deleted once we have dealt with them.
Deleting your data
Open Account and choose Delete my account and data. If your phone is gone, you can do the same on that page with your recovery phrase, from any browser, or write to us. Deleting:
- removes your device key, recovery phrase, age group, mutes and push subscriptions;
- removes every message you sent in table talk;
- hands your seat in any game still being played to a computer player (or ends a two-player game), so the other players can finish;
- unlinks you from every game. The moves of games you played with other people stay in their game records, under the display name they saw, because those games are theirs too. Nothing connects that name to you any more.
Your rights
Wherever you live, you can ask us what we hold about you, ask us to correct or delete it, or object to how we use it. Write to us and we will answer within 30 days. If you are in the EU or UK, you can also complain to your data protection authority.
Security
The game is served only over encrypted connections. We store hashes of your device key and recovery phrase, never the originals, so even someone reading our database could not take over your seat.
Changes
If this policy changes, we will update the date at the top. If a change affects what we collect, we will say so in the app before it takes effect.
