Privacy Policy

Effective Date: May 31, 2026

Introduction

Welcome to BlocksFusion! Your privacy is critically important to us. This Privacy Policy outlines the types of information we collect, how we use it, and the steps we take to ensure your data remains secure.

Information We Collect

  • Personal Information

    When creating an account, we collect your email address and username (passwords are securely managed by Auth0, our authentication provider).

  • Usage Data

    Information on how you interact with our platform, including pages visited, features used, and session duration.

  • Device Information

    Technical details like your IP address, browser type, and operating system.

  • Content You Create

    Scenes and builds you create, and game results such as your maze completion times, are stored on our servers so you can save, revisit, and share them. Shared builds and leaderboard entries may be visible to other players.

Device Sensors

Some games — like Gravity Maze — use your device's motion sensors (accelerometer / device orientation) so you can tilt your phone to control the game. These sensor readings are processed entirely on your device to compute tilt in real time. We do not transmit or store your raw motion data; only the outcome of a run (such as your completion time) is sent to our servers.

How We Use Your Information

  • Provide and enhance our services

  • Personalize your experience on BlocksFusion

  • Account management and security

  • Communicate updates, promotions, and important notices

Information Sharing

  • Third-Party Services

    We may share necessary data with trusted third parties for analytics, hosting, or customer support. Usage analytics are collected via Google Analytics and Amplitude, and authentication is handled by Auth0.

  • Session Recording (Sampled)

    A small sample of anonymous landing-page sessions (≈ 10%) is recorded via Amplitude's session-replay plugin. Recordings capture page interactions (clicks, scrolls, form input on non-sensitive fields) and help us improve the site. Editor surfaces (play.blocksfusion.com, projects pages) may record at higher rates when you're signed in.

  • Legal Compliance

    Information may be disclosed when legally required to comply with applicable laws or legal processes.

Data Security

We implement industry-standard security measures to protect your personal data from unauthorized access, alteration, disclosure, or destruction.

Your Data Rights

  • Access and review your personal data

  • Request corrections or updates

  • Request deletion of your account and associated data

Cookies

BlocksFusion uses cookies to improve your browsing experience, analyze traffic, and enhance platform performance.

Changes to this Policy

We may update our Privacy Policy periodically. We encourage you to review it regularly. Any significant changes will be communicated via email or prominently displayed on our website.
