// Lumen Crate is an offline logic puzzle where you hang job tags on a depot timetable until every rule card beside the board holds.
[01] Information collected // inputs
None. There is no sign-up, no login and no form that sends anything anywhere. The only thing you can type is a foreman name you choose yourself, and it stays on the device.
[02] Local storage // on-device
Kept in OS-level local storage on your device, never uploaded:
- The foreman name and mark you picked.
- Which boards you have settled and the stars each one earned.
- Your token balance, lifetime tokens and the daily-crate streak.
- Fittings bought in the shop, and commendations unlocked.
- Board aids and readability options (shaded legal slots, broken-card marking, shape-coded lanes, larger tag labels, still board).
- One board in progress, so you can leave mid-puzzle and pick it up later.
Uninstalling the app deletes every byte.
[03] Permissions // runtime
No runtime permissions are requested: no camera, microphone, location, contacts, photos, storage or notifications. The Android manifest carries android.permission.INTERNET from the standard Flutter project template; Lumen Crate has no networking code and never uses it. It is a normal, non-prompting permission, so you are never asked to grant it.
[04] Network // egress
None. Boards are generated on the device, art and fonts are bundled in the app, and nothing is downloaded, uploaded or synced. It plays the same in airplane mode.
[05] Third parties // vendors
No analytics, crash reporting, advertising, attribution or login SDKs are included. The app is built on open-source Flutter packages that run entirely on the device: Provider (state), Hive (local storage), Confetti and Flutter Animate (effects) and Collection (data helpers).
[06] Children // coppa/gdpr-k
Lumen Crate collects no personal information from anyone, including children under 13 (COPPA) or under 16 (GDPR-K). There are no ads, no purchases and no way to talk to other players.
[07] Your rights // you
Everything is local, so it is already in your hands. Uninstalling the app deletes all of it, or you can clear it any time under Settings → Apps → Lumen Crate → Storage → Clear data. Nothing reaches us, so there is nothing for us to export or erase.
[08] Changes // changelog
If this policy changes, the updated field at the top of this page will be revised. Material changes are also noted in the app's release notes.
