Privacy Policy
Last updated: 1 November 2026
Lantern Line is a game about running one metro line. This document describes what data the app does — and does not — collect.
Short version
- Lantern Line collects nothing. There is no account of mine, no analytics, no crash reporting, no advertising, and no tracking across other apps.
- It plays entirely offline. The game needs no connection. The two things that can leave your device are your saved game, which goes to your own iCloud so the same line follows you between your devices, and a Game Center score — and each only if you are signed in to that service.
- Your saved game and settings are stored on your device and in your own private iCloud storage. I have no access to either.
- Purchases are handled by Apple's App Store. Lantern Line never sees your payment details.
What is stored
The following are stored on your device using the operating system's standard app storage, and — if you are signed in to iCloud — a copy is kept in your own private iCloud storage so you can carry on the same game on another device:
- Your saved game — your stations and kiosks, your train, your coins and tokens, and which regulars you have met
- Which missions you have completed and which looks you own
- Your settings, such as music, sound, haptics, reduced motion and your quiet hours
If you delete the app, the copy on that device is removed with it. The iCloud copy is removed when you delete the app from every device, or from iOS Settings under your Apple Account.
What is sent over the network
Lantern Line has no server of its own, no account system of its own and no analytics, so there is no place of mine for your data to go. Everything the game needs to play is inside the app, which is why it keeps running with no signal.
The two exceptions are iCloud and Game Center, described below. Both are Apple's services, used with the Apple Account already signed in on your device, and both are covered by Apple's privacy policy rather than by anything of mine.
iCloud
If you are signed in to iCloud, your saved game is kept in your own private iCloud storage, which is what lets you put your phone down and carry on from your iPad. It is the same save described above — your line, your stations, your wallet and your settings — and nothing more. It goes to your own Apple Account storage, not to any server of mine, and I cannot see it, read it or recover it for you.
If you are signed out of iCloud, the game keeps the save on the device alone and plays exactly the same. You can stop it syncing at any time by turning iCloud Drive off for Lantern Line in iOS Settings.
If the same game has been played further on two devices without them having a chance to sync, the game asks you which one to keep rather than choosing for you.
Game Center
If you are signed in to Game Center on your device, the game submits four numbers to Apple's leaderboards: how many stations you have built, how many regulars you have met, how many coins you have earned and how many perfect stops you have landed. Those scores sit under the Game Center nickname you chose with Apple, and who can see them is governed by your own Game Center privacy settings, not by anything in this app.
Nothing else is sent, and nothing is sent at all if you are signed out of Game Center or decline it. The rest of the game is unaffected either way: no part of playing depends on a score being accepted.
Notifications
If you turn notifications on, the app asks iOS to show you a reminder when something you started has finished — a kiosk restocked, a station built. Those reminders are scheduled on your device by iOS and are not sent through any server of mine. You can turn them off inside the game or in iOS Settings, and you can set quiet hours so nothing arrives overnight.
Purchases
Lantern Line offers token packs, a few optional looks for the train and stations, and a supporter purchase. Every transaction is handled entirely by Apple through the App Store. The app receives only a confirmation from the operating system that the purchase belongs to the Apple Account signed in on the device; it never sees your name, your payment details or your Apple Account.
Third-party services
None. Lantern Line includes no analytics SDK, no crash-reporting service, no advertising SDK and no other third-party tracking.
Children
Lantern Line is rated 4+ and does not knowingly target or collect data from children under 13. Since the app collects no data from anyone, it collects none from children either.
Permissions
Notifications, and only if you turn them on. Lantern Line does not request your location, contacts, photos, camera, microphone, App Tracking Transparency, or background activity.
Changes to this policy
If this policy changes in the future, the updated version will be published at the same URL where you are currently reading it, and the "Last updated" date above will change.
