Privacy Policy

Last updated: January 14, 2026

🔒 Introduction

Welcome to Block Blast ("we," "our," or "us"). We are committed to protecting your privacy. This Privacy Policy explains our minimal data collection practices when you use our mobile puzzle game.

In short: We collect almost no personal data. Your privacy is our priority.

📊 Information We Collect

1. Optional Display Name Only

The ONLY personal information we collect is:

  • Display Name: An optional username you can provide for the leaderboard (completely voluntary)
  • If you don't provide a name, we generate a random fun name like "SwiftPuzzler42"
  • This name is stored anonymously and cannot be traced back to you

2. Anonymous Game Data

We store anonymous gameplay statistics to make the leaderboard work:

  • Anonymous Player ID: A random unique identifier (not linked to any personal info)
  • Game Scores: Your scores and levels completed
  • Gameplay Stats: Number of games played, best scores

This data is completely anonymous and cannot identify you personally.

3. What We DO NOT Collect

We explicitly DO NOT collect:

  • ❌ Email addresses
  • ❌ Phone numbers
  • ❌ Real names
  • ❌ Location data
  • ❌ Contact lists
  • ❌ Photos or media
  • ❌ Device identifiers (IMEI, MAC address)
  • ❌ Browsing history
  • ❌ Any other personal information

🎯 How We Use Your Information

The minimal data we collect is used only for:

  • Leaderboard Display: Showing your optional display name and scores
  • Game Progress: Saving your game progress locally on your device
  • Gameplay Experience: Remembering your settings and preferences

🔗 Third-Party Services

Firebase (Google)

Advertising (If Applicable)

💾 Data Storage and Security

👶 Children's Privacy

Our game is suitable for all ages and is safe for children:

  • We do not collect any personal information from children
  • No account creation or email is required
