// GreatWin is a memory pair-matching game played across thirty neon club floors, entirely on your device.
[01] Information collected // inputs
None. There is no sign-up, no account, no profile and no login. The app never asks for your name, e-mail address, phone number or any other identifier, and it has no way to send one anywhere even if you typed it in.
[02] Local storage // on-device
Kept in OS-level local storage on your device, never uploaded:
- Per-floor progress: which of the thirty floors are unlocked and cleared, the stars earned on each and your best run.
- Lifetime statistics shown on the Dossier: floors cleared, stars banked, pairs found, best chain and runs played.
- Your Prism balance, the tier of each of the four permanent Forge upgrades, and how many Glimpse, Undo and Pounce consumables you hold.
- Daily tribute state: the date of the last claim and the current return streak.
- Which of the nine merit badges have been unlocked.
- Accessibility and audio preferences: face codes, calm lights, wide pads, sound and music toggles.
- A snapshot of a run in progress, so an interrupted floor can be resumed.
Uninstalling the app deletes every byte.
[03] Permissions // runtime
No runtime permissions are requested. GreatWin never asks for the camera, the microphone, location, contacts, photos, storage or notifications, and the system will never show you a permission dialog for it. The Android manifest carries the install-time INTERNET permission that ships with the default Flutter project template, but the app contains no networking code and issues no requests — see the Network section below.
[04] Network // egress
The app is fully offline. It opens no sockets, contacts no server, and loads nothing from the internet — every board, image, sound and font is bundled into the installed package. Nothing you do in GreatWin leaves your device, and the whole game works in airplane mode. The only outbound action that exists is the optional Share button, which hands a short text summary you wrote yourself to the Android share sheet — you choose the destination app, and that app's own privacy policy takes over from there.
[05] Third parties // vendors
None. There is no analytics SDK, no advertising SDK, no crash reporter, no attribution or install-referrer library and no in-app billing. The app is built on the open-source Flutter framework and a small set of local utility packages (a local SQLite store, state management, animation and formatting helpers); none of them transmit anything.
[06] Children // coppa/gdpr-k
GreatWin is suitable for all ages. Because it collects no personal information at all, from anyone, it is compliant with COPPA and with the GDPR provisions on children's data by construction: there is nothing to collect, nothing to profile and nothing to consent to. There are no ads, no purchases and no social or chat features.
[07] Your rights // you
Every piece of data described above lives in a private database inside the app's own sandbox on your device. You can clear it at any time from the Android app settings (“Clear storage”), or delete it completely by uninstalling the app. Because nothing is ever uploaded, there is no server copy, no backup on our side and therefore no access, correction, export or erasure request to file with anyone.

[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.
