Privacy Policy

Last Updated: October 17, 2026

1. Introduction

Welcome to Merge Blocks 2048 ("we", "our", or "us"). We respect your privacy and are committed to protecting it through transparent data practices. This Privacy Policy explains how information is collected, used, and safeguarded when you play the Merge Blocks 2048 mobile application on iOS and Android.

By downloading, installing, or playing Merge Blocks 2048, you agree to the collection and use of information in accordance with this policy.

2. Information We Do NOT Collect

We believe in data minimization. Merge Blocks 2048 does NOT collect:

  • Your real name, physical address, or phone number.
  • Your contacts list, photos, camera, or microphone data.
  • Precise GPS location data.
  • Payment or financial card information (all transactions are securely handled directly by Apple App Store or Google Play Billing).

3. Information We Collect & Why

A. Anonymous Player Identifier

When you launch the app, Firebase Anonymous Authentication creates a randomized, pseudonymized user ID (e.g., uid: a9f8...). This identifier connects your high scores and unlocked achievements to the global leaderboard without requiring personal email or social logins.

B. Gameplay & Leaderboard Data

When you finish a game with internet connectivity, the following game state metrics are submitted to our Cloud Firestore database:

  • Display player name (a customizable nickname, e.g. "Player 42")
  • Chosen avatar ID (built-in emoji or character icon)
  • Final score and highest tile reached (e.g. 2048, 4096)
  • Timestamp of submission

C. Crash Reports & Performance Metrics

We use Firebase Crashlytics to diagnose unexpected crashes and fix software bugs. Collected crash data includes device model, operating system version, app version, and stack traces at the time of failure. No personally identifiable details are attached.

D. Non-Personalized Analytics

We use Google Analytics for Firebase to understand aggregate gameplay trends (such as average game session length, popular game modes, and booster usage). This helps us balance difficulty and optimize game performance.

E. Advertisements (Google AdMob)

Merge Blocks 2048 displays advertisements via Google AdMob to keep the core game free. AdMob may collect and process device advertising identifiers (such as Google Advertising ID or IDFA) according to your device settings to serve contextual or personalized ads, control ad frequency, and measure ad performance.

4. Local Storage on Your Device

The majority of your game data — including sound/music settings, haptic preferences, daily streak calendar, booster inventory, and offline high scores — is stored locally on your device via encrypted local preferences (SharedPreferences on Android / NSUserDefaults on iOS). You can clear this data at any time by uninstalling the application or clearing app storage in device settings.

5. Third-Party Service Providers

We partner with trusted third-party providers who operate under strict privacy and security standards:

6. Children's Privacy (COPPA & GDPR-K)

Merge Blocks 2048 is designed for general audiences of all ages. We do not knowingly collect personal information from children under the age of 13 (or under 16 in the European Union). If you are a parent or guardian and believe that your child has provided personal information to our servers, please contact us and we will promptly delete the data.

7. Data Retention & Deletion Rights

We respect your right to control your personal and gameplay data. Under applicable privacy regulations (including GDPR, CCPA, and Google Play Data Safety requirements), you have the right to request deletion of all data associated with your gameplay, leaderboard submissions, and pseudonymized identifier.

Google Play & App Store Compliance
