DeckHouse is a multiplayer card game. This page explains what information the app collects, why, and how it's used. There is no account sign-up, no email address or password, and no real-name identity involved anywhere in the app.
When you open the app, it creates an anonymous guest session (Firebase Anonymous Authentication). This gives your device a random ID used to identify you as a player in a room — it is not tied to your name, email, or any other personal account, and there's no password or sign-up step.
You choose a display name shown to other players in any room you join. It's stored so other players in your room can see who they're playing against, and is visible to them for as long as the room exists.
Creating or joining a room stores the room's name, join code, configuration (deck count, minimum value, max players), and live game state (whose turn it is, cards played, scores) so the game can run in real time between everyone in that room. This data is only visible to players in the same room.
Your chosen avatar, game settings, favorited games, and personal win/loss stats are stored only in the app's local storage on your device. None of it is uploaded to any server or seen by other players.
DeckHouse uses Sentry to catch crashes and diagnose performance issues (app start time, dropped frames, slow screens). When something goes wrong, Sentry receives a crash report along with basic device/app diagnostics (device model, OS version, app version) and a short history of which screens you'd recently visited — never your display name, join code, or anything from inside a game. It is not used for advertising, analytics on your behavior, or tracking across other apps.
A room and its data (players, join code, game state) are automatically deleted after 24 hours of inactivity. Leaving a room removes you from it immediately. Your locally stored display name, avatar, preferences, and stats stay on your device until you remove them or delete the app.
Room and gameplay data is stored in Google Firebase (Realtime Database and Cloud Functions), used purely as backend infrastructure to run the game — Google does not use this data for its own purposes. Crash reports and performance data (see above) are stored by Sentry, used purely to help us find and fix bugs.
DeckHouse does not knowingly collect personal information from anyone, including children — there's no name, email, or other identity data collected at all, by design.
