Privacy Policy

MarsRover Mine, Build, Breathe · Last updated: 2026-10-20

Traista Rafael built MarsRover Mine, Build, Breathe as a free game supported by optional advertising. This SERVICE is provided by Traista Rafael and is intended for use as is.

This page is used to inform visitors regarding my policies with the collection, use, and disclosure of Personal Information if anyone decided to use my Service.

If you choose to use my Service, then you agree to the practices described in this Privacy Policy. The terms used in this Privacy Policy have the same meanings as in our Terms and Conditions unless otherwise defined here.

Summary

• Your expedition is saved only on your device. There are no accounts, no sign-in and no cloud save.
• The game sends anonymous usage statistics to Google Analytics for Firebase, so I can see how the game is played and where players get stuck.
• The game offers optional rewarded videos through Google AdMob.
• Your device's advertising ID is used only with your consent, to show more relevant ads and to tell which of my own ads brought you to the game.
• No in-app purchases, no payment details, no location, contacts, photos, camera or microphone.

Information Stored on Your Device

Your expedition — your save file, your map seed, your credits, contracts, upgrades, everything in your store room — and your settings (sound and language) are stored locally on your device. They are never transmitted to me or to any server. There is no remote database and no cloud backup: uninstalling the app or clearing its data removes them.

The game has no user accounts, no sign-in, no profiles, and no multiplayer features. It does not ask for your name, your email address, or any other personal detail, and it does not request access to your contacts, photos, files, microphone, camera, or location.

Usage Analytics (Google Analytics for Firebase)

The game uses Google Analytics for Firebase, a service provided by Google, to record anonymous usage statistics. I use them to understand how the game is played — how far expeditions get, where players lose rovers, which features are used — so I can improve it.

What is recorded:

• Gameplay events, such as starting or resuming an expedition, losing or recovering a rover, completing a mission, building an upgrade, buying equipment, selling or ordering ore, reaching an oxygen milestone, finishing the game, opening or closing the landing briefing, and choosing to watch a rewarded video. These events carry game figures only (for example minutes played, oxygen percentage, or which mission was completed).
• Play time and screens: how long a session lasts and which game screen is open.
• Information Firebase collects automatically: a random app-instance identifier generated for this installation, the first time the app was opened, device model, operating system and version, app version, language, and approximate country or region derived from your IP address. Google does not give me your IP address.

What is not recorded:

• No name, email, account or user ID of any kind — I never set one.
• No Android ID and no iOS identifier for vendor (IDFV); both are switched off in the app.
• No precise location, no contacts, no free-text input, and nothing about your save file beyond the game figures listed above.
• Google Signals (cross-device tracking linked to Google accounts) is turned off for this game.

Analytics data is kept by Google for 2 months for event-level data and up to 14 months for data tied to the app-instance identifier, after which it is deleted automatically. I only see aggregated reports.

Advertising (Google AdMob)

The game offers optional rewarded advertisements provided through Google AdMob. You are never required to watch an advertisement to play. A video is shown only when you press a button marked as an ad, in exchange for a reward — recovering a rover that has broken down, receiving a unit of ore, patching your hull or drill, or topping up your battery.

To have a video ready when you ask for one, the app connects to Google AdMob when it starts and loads an ad in the background. Google AdMob may collect and process information such as device identifiers, the advertising ID, IP address, and information about your interaction with ads in order to serve and measure advertising. This data is handled by Google in accordance with its own privacy policy; I do not receive it.

Advertising in the game is limited to ads suitable for general audiences (Google's "G" content rating), and the game is not directed at children.

Advertising ID, Consent and App Tracking Transparency

Your device's advertising ID (the Google Advertising ID on Android, the IDFA on iOS) is used for two purposes: by Google AdMob to show more relevant ads, and by Google Analytics for Firebase to tell me which of my own advertising campaigns (Google Ads) brought you to install the game. It is not used to build advertising audiences or remarketing lists from your gameplay — that signal is always switched off.

• In the European Economic Area, the United Kingdom and Switzerland, the game shows Google's consent form (a certified consent management platform using the IAB Transparency & Consent Framework) before any personalised advertising or ad measurement takes place. Your answer is passed to AdMob and to Google Analytics, and nothing advertising-related is used unless you agree. If you decline, you still get non-personalised ads and the game plays exactly the same.
• On iOS, the game asks for permission through Apple's App Tracking Transparency prompt. If you do not allow tracking, the IDFA is never read, ads are not personalised, and ad measurement is switched off for analytics.
• Elsewhere on Android, the advertising ID is used for the two purposes above unless you have opted out in your device settings.

Analytics collection does not start until this consent step is finished, so the first launch is recorded with the choice you made.

You can change your choice at any time:

• iOS: Settings → Privacy & Security → Tracking.
• Android: Settings → Google (or Privacy) → Ads, where you can delete or reset your advertising ID.
• EEA, UK and Switzerland: clearing the app's data shows Google's consent form again on the next launch; you can also contact me.

Without an Internet Connection

The game can be played from start to finish offline. With no connection, the rewarded-video buttons become inactive and nothing is sent; analytics events recorded while offline may be sent by the Firebase SDK the next time a connection is available.

In-App Purchases and Payments

There are none. The game contains no in-app purchases, no subscriptions, and no premium currency. Nothing in the game is for sale, so no payment or billing information is ever requested, processed, or stored.

Service Providers

The game relies on the following third-party services from Google LLC, which may have access to limited information as described above in order to provide their functionality:

• Google Analytics for Firebase (usage analytics and install attribution)
• Google AdMob (rewarded advertising), including Google's User Messaging Platform for consent

They are obligated to handle any information they receive in accordance with their own privacy policies:

• Google Privacy Policy: https://policies.google.com/privacy
• How Google uses information from apps that use its services: https://policies.google.com/technologies/partner-sites
• Firebase privacy and security: https://firebase.google.com/support/privacy

Data handled by Google may be processed on servers outside your country, including in the United States.

Security

I value your trust. Your save data stays on your device and under your control. Information sent to Google Analytics for Firebase and Google AdMob is transmitted over encrypted connections and secured by Google. No method of transmission over the internet or method of electronic storage is 100% secure, and I cannot guarantee absolute security.

Links to Other Sites

This Service may contain links to other sites — for example, from within an advertisement. If you click on a third-party link, you will be directed to that site. Note that these external sites are not operated by me. Therefore, I strongly advise you to review the Privacy Policy of these websites. I have no control over and assume no responsibility for the content, privacy policies, or practices of any third-party sites or services.

Children's Privacy

These Services do not address anyone under the age of 13. I do not knowingly collect personally identifiable information from children under 13 years of age, and the analytics described above contain no name, email or account. If you are a parent or guardian and you believe that your child has provided personal information through the services listed above, please contact me so that I can take the necessary actions.

Your Rights

Depending on where you live (for example under the GDPR in the EEA and UK, or under US state privacy laws), you may have the right to access, correct, delete or object to the processing of your personal data, and to withdraw consent at any time. The legal basis for the analytics described above is my legitimate interest in understanding and improving the game; advertising personalisation and ad measurement rely on your consent where the law requires it.

Because I do not know who you are, I can only act on analytics data through the app-instance identifier. To have it deleted, contact me and I will explain how to find it; alternatively, uninstalling the app resets it, and the old data expires automatically after the retention periods above. Your save data can be removed at any time by clearing the app's data or uninstalling the app. You also have the right to lodge a complaint with your local data protection authority.

Changes to This Privacy Policy

I may update this Privacy Policy from time to time. Thus, you are advised to review this page periodically for any changes. I will notify you of any changes by posting the new Privacy Policy on this page.

This policy is effective as of 2026-10-20.
