Line Knight is a puzzle game. We built it so that it collects no personal information.
The game has no accounts and no sign-in of its own, and it contains no advertising or tracking. To find bugs and to see which levels are too hard, it sends anonymous usage and crash information to Google Firebase (Google Analytics for Firebase and Firebase Crashlytics):
This information is not linked to your name, email, contacts or any account. No advertising identifier (IDFA) is collected, and nothing is used to track you across other apps or websites or for advertising. Google processes it on our behalf under the Firebase privacy terms; we only see totals and crash reports.
Your level progress, stars, coins, unlocked knights and settings are saved on your device. So that you don't lose them when you change or reset your phone, a copy is also kept in your own cloud storage: in your iCloud account on iPhone and iPad, and in your Google account's device backup on Android. These copies are handled by Apple and Google under their privacy policies; we cannot see them. You can erase your progress at any time from Settings → Reset Progress.
On iPhone and iPad, if you are signed in to Game Center, your total stars, furthest level and achievements are sent to Apple's Game Center so they can appear on leaderboards. This is handled by Apple, and you can turn Game Center off in your device's Settings.
If you allow it, the game schedules a few local reminders on your device (for example when your hearts are full). They are created on the device itself; nothing is sent to us. You can turn them off in the game's Settings or in your device's Settings.
If the game offers coins, hearts or bundles for purchase, payment is handled entirely by the App Store or Google Play under their own policies; we never receive your name, card or payment details.
If you tap Share, your device's own share sheet opens with a short text message about your result. Nothing is sent unless you choose where to share it.
Line Knight does not knowingly collect information from anyone, including children under 13.
If a future version adds features that change this policy (for example optional in-app purchases), we will update this page before that version is released.
