Casual Tank – Privacy Policy
Last updated: 20 October 2026
Who we are
Casual Tank is an online artillery game made by an independent developer ("we"). Contact: 1076357483@qq.com.
What we collect
- Account data – a guest account is created automatically (a random player name and password stored on your device). If you register, we keep your username and a salted hash of your password. We never ask for your real name, email or phone number.
- Game data – coins, gems, cosmetic items, rating, quest progress, weapon set-ups and match results.
- Purchases – for in-app purchases we send the App Store receipt to our server to check it with Apple and record the transaction ID, so gems are delivered exactly once. We never see your payment details.
- Technical data – the IP address of your connection is used to run the game and to limit repeated failed logins; it is not stored with your profile. The Unity engine may send anonymous hardware statistics (device model, OS version) to Unity Technologies.
How we use it
Only to run the game: log you in, save your progress, match you with other players, show your name and look to the players in your battle, and deliver purchases. We have no advertising, no third-party trackers, and we do not sell or share your data.
Where it is stored
On our game server in Hong Kong. Data is sent over encrypted connections (TLS).
Deleting your account
In the game open Settings → Delete account. Your game data is deleted at once and the account can no longer be used. You can also ask us by email. Records of App Store transaction IDs are kept (without personal data) so that a purchase cannot be paid out twice.
Children
The game is not directed at children under 13 and we do not knowingly collect personal information from them.
Changes
If this policy changes we will update this page and the date above.
