Cube Siege is a game. We collect as little as possible, never sell data, show no ads and do not track you across other apps or websites.
What we process and why
| Data | Why | When |
|---|---|---|
| A random player ID created by Unity Authentication | To keep your progress and connect co-op games | Always (no name or email) |
| Game progress: unlocked stages, best scores, tutorial, garage (level, stat points, modules, bolts), crystal balance, skins owned and battle-pass progress | To back up your progress (Unity Cloud Save) | Always |
| Your nickname (you choose it in Settings) | To show it over your tank to the other players in battles and co-op | Sent to the game server or your co-op partner only while you play online |
| In-app purchases: the product and Apple's transaction ID | To add the crystals you bought (payment itself is handled only by Apple; we never see your card details) | When you buy crystals |
| Your Apple ID's anonymous user identifier | To restore progress on a new device | Only if you tap “Sign in with Apple”. We do not request your name or email. |
| Gameplay statistics: stages started and cleared, battles, scores, level-ups, whether you played co-op, what you bought with crystals and crystal purchases; device model, OS version and approximate country as recorded by Google Analytics for Firebase | To understand which stages are too hard and improve the game | Only if you allow it (asked once, changeable in Settings) |
| Crash reports: device model, OS version, app version, technical error details | To find and fix crashes | Only if you chose to share analytics with app developers in iOS Settings; delivered by Apple |
| Your IP address (processed transiently by the connection services) | To connect you with a friend in a co-op game (Unity Relay) or on the same Wi-Fi, and for online battles: to find a match (our matchmaker on Cloudflare) and to start a battle server near you (Edgegap) | Only while you host or join a co-op game or play an online battle |
| Game Center score | To show the leaderboard | If you are signed in to Game Center; handled by Apple under Apple's privacy policy |
