tank battle: firefall city

Privacy policy

last updated · October 31, 2026

This policy explains what the Tank Battle: Firefall City game for iPhone, iPad, Mac and Android (“the game”) does with information, and what its developer, Alexej Penzencev (“we”, “us”), receives. You can reach us at apps@lexpenz.com.

01What we collect

Nothing. The game has no account or sign-in, no server of its own, and no advertising, analytics or tracking code. It contains no third-party SDKs that collect data. We don't sell, share or even receive information about you or how you play.

02What is stored on your device

The game keeps a few things in its own storage on your device, and only there:

• Progress: which stages you have unlocked, and your scores.
• Settings: such as the language and whether cheat mode is switched on.
• Your stages and campaigns: the ones you build or import.

None of it is sent to us. Deleting the game deletes it. Like all app data, it may be included in your device's own backups (for example iCloud or Google backups) if you have them turned on; those are handled by Apple or Google and are not readable by us.

03Two-player games on your local network

For a two-player game, the devices find each other on your Wi-Fi with Bonjour (local network discovery) and then exchange the game directly, device to device. This traffic stays on your local network: nothing goes over the internet, and there is no server in between.

• On iPhone, iPad and Mac, the system asks for Local Network permission the first time you play together. It is used only for this. You can change it any time in Settings (on a Mac, System Settings) → Privacy & Security → Local Network.
• The game talks only to the other player's device, and only while you are playing together.

04Sharing stage and campaign files

Stages and campaigns you share are saved as .cotstage and .cotcampaign files (JSON) and handed to the system share sheet or to Files. They go only where you choose to send them, and never to us. Files you import are read on your device.

05The optional purchase

Cheat mode is bought through the Apple App Store or Google Play, which handle the payment entirely. We never see your payment details, your Apple ID or Google account, or any other personal data. The game only asks the store whether cheat mode has been bought, so it can unlock it and restore it on your other devices. Apple and Google process this under their own policies: Apple Privacy Policy, Google Privacy Policy.

06Ads, analytics and tracking

There are none. The game shows no ads, doesn't measure how you play and doesn't track you across apps or websites.

If you have chosen in your device settings to share diagnostics with app developers, Apple or Google may give us anonymous crash reports and aggregate figures for the game. They come without your identity, and we use them only to fix problems.

07When you contact us

If you email us, we receive your email address and what you write. We use it only to answer you, don't share it with anyone, and delete the conversation when it is no longer needed to help you.

08This website

This website uses no cookies, analytics, trackers or external scripts. It is hosted on GitHub Pages, and GitHub may log visitors' IP addresses for security, as described in the GitHub Privacy Statement.

09Children

The game collects no personal information from anyone, children included.

10Your rights and choices

• You can turn Local Network access on or off at any time in your device's settings.
• Deleting the game removes everything it has stored.
• Because we hold no data from the game, there is nothing for us to access, correct, export or delete about you. Under the GDPR, the UK GDPR, the CCPA and similar laws you can still ask us about any emails you've sent us, ask us to delete them, or complain to your data protection authority.
• We don't sell or share personal information, as those terms are defined by the CCPA.

11Changes to this policy

If the game starts handling information differently, we will update this policy and the date at the top before that version of the game is released.
