Privacy policy

Last updated: 5 October 2026

This policy covers Martian Frontier: Defense (Марсианский рубеж), version 0.1.0, and this support website. The developer is Alex Fedotov.

Progress on your device

Campaign progress, research, saved battles, sound and language settings are stored locally on your device. The game has no developer account system or developer-operated progress server. Deleting the app may remove this data.

Purchases through Apple

Optional purchases and their restoration use Apple StoreKit. Apple processes payments; the developer does not receive your card details. The app verifies purchase entitlement and stores the research entitlement locally. Restoring a purchase does not restore campaign progress.

External fonts

The current app version may request fonts from Google Fonts when connected to the internet. These requests send Google your IP address, requested URL and technical HTTP headers, which can include browser and operating system information and a referring URL. Google states that its Fonts API does not set or log cookies and does not use this information to create advertising profiles. See the Google Fonts privacy FAQ and Google Privacy Policy.

Advertising and device access

This version has no advertising or analytics SDK, social sign-in or tracking implementation. It does not request access to your camera, microphone, location or contacts.

This website

This website has no analytics, advertising, cookies or external font loading. Serving a page requires the hosting infrastructure to process your IP address and technical request information. These requests are distinct from game progress, which is not sent to this website.
