Privacy Policy

Introduction

This Privacy Policy describes how Marlin Game Studio ("we," "us," or "our") collects, uses, shares, and protects information when you use the Falling Blocks mobile application ("Application," "App," or "Service"). The App was previously named Retro Block Duo, and this Policy applies to it under both names.

By downloading, installing, or using the Application, you agree to the collection and use of information in accordance with this Policy. If you do not agree, please do not use the Application.

Information We Collect

Automatically collected information

When you use the Application, we and our service providers may automatically collect:

• Device information: device type, operating system version, language, and device identifiers such as the Identifier for Advertisers (IDFA, only if you allow tracking) and the Firebase app instance ID.
• Game Center information: if you are signed in to Game Center, your Game Center player ID, so that we can submit your scores and achievements. Game Center itself is run by Apple.
• Usage data: game modes and levels played, results, scores, in-game purchases and boosters used, ads viewed, session length, and similar interactions.
• Purchase information: which in-app purchases you have made. Payment details are handled entirely by Apple, and we never see them.
• Technical data: IP address, crash logs, and diagnostic and performance information (such as loading time and frame rate).

Your game progress (levels, coins, boosters, settings) is stored on your device. We do not ask you to create an account, and we do not ask for your name, address, phone number, or email address. Location: the Application does not collect or access your precise location.

How We Use Information

• Running the game: to provide, maintain, and improve the Application, including game balance and difficulty.
• Leaderboards and achievements: to submit your scores and achievements to Game Center.
• Purchases: to deliver and restore the items you buy.
• Advertising: to show ads and measure how they perform. The free version of the Application is supported by ads.
• Analytics and diagnostics: to understand how the Application is used, find and fix crashes, and improve performance.
• Reminders: if you allow notifications, to remind you of your daily streak or a game in progress. See "Notifications" below.
• Configuration: to adjust game settings (such as prices, ad frequency, and level tuning) without releasing an update.
• Support and legal: to answer your questions, protect against fraud and abuse, and comply with the law.

Advertising, Tracking, and Your Consent

The Application shows ads through Google AdMob. Remove Ads, a one-time purchase, turns off banner and full-screen ads. Rewarded videos stay available, since you choose whether to watch them.

• App Tracking Transparency: on iOS, the Application asks whether it may track you across other companies' apps and websites. If you decline, the IDFA is not used, and ads are not personalized using it. You can change this at any time in iOS Settings.
• EEA, UK, and similar regions: Google's User Messaging Platform shows a consent form before any ad or analytics storage is used. You can review or withdraw your choices at any time from Settings → Privacy settings inside the Application.

Notifications

If you allow notifications, the Application schedules reminders on your device, such as one to keep your daily streak. They are local notifications: they are created and delivered by your device, and no server or push service is involved. We ask for permission only once, after you have played on several days, and you can turn reminders off at any time in Settings inside the Application or in iOS Settings.

Information Sharing and Disclosure

We do not sell your personal information. We share information only with the service providers listed below, who process it on our behalf for the purposes described above, and when the law requires it.

Legal requirements

We may disclose information when we believe in good faith that it is necessary to:

• Comply with a subpoena, court order, or similar legal process
• Protect our rights, property, or safety, or that of our users or others
• Investigate fraud or respond to a government request

Third-Party Services

The Application uses the following third-party services. Each has its own privacy policy that governs how it handles data:

• Google AdMob (advertising): AdMob privacy
• Google User Messaging Platform (consent): Google Privacy Policy
• Google Analytics for Firebase (analytics), Firebase Crashlytics (crash reports), and Firebase Remote Config (game settings): Firebase privacy
• Apple Game Center (leaderboards and achievements) and Apple App Store (in-app purchases): Apple Privacy Policy

These providers may use identifiers and similar technologies to collect information about your use of the Application and of other apps.

Your Rights and Choices

Depending on where you live and applicable law, you may have the right to:

• Access the personal information we hold about you
• Delete your personal information (subject to legal requirements)
• Restrict or object to certain processing
• Withdraw consent you have given

You can also limit collection yourself:

• In the Application: Settings → Privacy settings (where available).
• On your device: turn off tracking for the Application in iOS Settings, or reset your advertising identifier.
• Uninstall: removing the Application stops all collection by the Application.

To make a request, email us at retroblockduo@gmail.com. We do not keep your name or email, so we cannot look up a person's data ourselves; the device-side choices above are the most direct way to stop collection and remove the data stored on your device.

Children's Privacy

Falling Blocks is a general-audience game and is not directed at children under 13. We do not knowingly collect personal information from children under 13. If you are a parent or guardian and believe your child has used the Application, you can stop all collection on that device: delete the Application, turn off tracking for it in iOS Settings, and reset the advertising identifier. We have no accounts, names, or email addresses, so we cannot look up a person's data ourselves. Questions? Contact us at retroblockduo@gmail.com.

The Application has no chat or social features, and it does not ask for names, addresses, phone numbers, or location.

International Data Transfers

Your information may be transferred to and processed in countries other than your own, which may have different data protection laws. When we transfer information internationally, we rely on appropriate safeguards offered by our service providers.

California Privacy Rights (CCPA)

If you are a California resident, you have the right to:

• Know what personal information is collected, used, and shared
• Delete personal information
• Opt out of the sale or sharing of personal information (we do not sell personal information)
• Non-discrimination for exercising your privacy rights

To exercise these rights, contact us at retroblockduo@gmail.com.

European Privacy Rights (GDPR)

If you are in the European Economic Area or the UK, you have the rights listed under "Your Rights and Choices," and you may complain to your local data protection authority. Our legal bases for processing are:

• Consent: for analytics storage and personalized advertising, which you give or refuse in the consent form
• Legitimate interest: to operate, secure, and improve the Application
• Contract: to deliver the purchases you make
• Legal obligation: to comply with applicable laws

Contact

If you have questions or requests about this Privacy Policy or our data practices, contact us:

• Email: retroblockduo@gmail.com
• Response time: we aim to reply within 30 days.

Changes to This Policy

We may update this Policy from time to time. When we make material changes, we will update the "Last updated" date above and, where the law requires it, tell you in the Application. Continued use of the Application after a change means you accept the revised Policy.
