| 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 the App Store's or Google Play's transaction ID | To add the crystals you bought (payment itself is handled only by Apple or Google; we never see your card details) | When you buy crystals |

| Your Google Play Games player ID (Android) | To restore progress on a new device and show the leaderboard | When you are signed in to Google Play Games. 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), or through Google Play's Android vitals on Android |
| 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 / Google Play Games score | To show the leaderboard | If you are signed in to Game Center or Google Play Games; handled by Apple or Google under their privacy policies |
