Privacy Policy

1. Information we collect

Game progress and completed results are stored on your device and are not sent to the Operator’s server.

Only when you enable usage-data sharing in the mobile app settings or consent on the web version, Firebase Analytics may collect:

• Missions selected, started, resumed, and completed
• Month reached, outcome, score, rank, and selected business model
• Use of result history and sharing features
• In-app product, price, currency, and purchase events
• App launches, screen views, sessions, and similar usage activity
• Web pages viewed, trial-button actions, referrer, browser, and device type
• App version, device type, OS, language, and approximate region
• An identifier generated for each app installation

We do not collect your name, phone number, precise location, advertising ID, credit-card number, or other payment method. Fictional in-game revenue and cash are not treated as your financial information.

When you buy or restore the full game, Apple App Store or Google Play supplies product information, purchase status, and a transaction identifier so the app can verify access. Verified access is cached on the device for offline play. The current app does not send this information to the Operator’s server. If usage-data sharing is enabled, product, price, currency, and purchase-event data may be sent to Firebase Analytics, but transaction identifiers and payment methods are not sent.

If you contact us, we receive your reply email address, the information in your message, and any attachments you choose to send. Do not send personal or confidential information that is not needed for support.

2. Purposes

• Improve mission difficulty and game balance
• Understand feature usage and improve quality
• Investigate bugs and improve stability

We do not use collected information for advertising, ad personalization, or sale.

3. External services

We use Firebase Analytics provided by Google LLC. Submitted information may be processed on Google infrastructure and is handled under the Google Privacy Policy and Firebase Terms.

Purchases use Apple App Store on iOS and Google Play on Android. Purchase processing, refunds, and store-account purchase history are handled under each store’s terms and privacy policy.

4. Retention and deletion

You can delete progress and completed results from Settings. Uninstalling the app also removes its local game data.

Apple App Store or Google Play manages full-game purchase history. Uninstalling does not remove store purchase history, and you can restore it after reinstalling with the same store account.

Firebase Analytics user-level and event-level data is generally configured for a two-month retention period. This period may not apply to aggregated statistics.

Turning usage-data sharing off stops future transmission. The mobile app resets local Analytics data and its app-instance identifier. Existing web cookies can be removed through browser settings.

Support messages are retained only as long as needed for support and prevention, and are generally deleted within one year after resolution unless law requires longer retention.

5. Your choices

Usage-data sharing is off by default. You can play free and purchased missions without sharing it, and change the setting at any time.

6. Security

We limit collection to what is necessary, do not use advertising identifiers, and use safeguards provided by our external service providers.

7. Contact

If collected information or its purposes change, we will update this screen and provide in-app notice of material changes.
