PRIVACY POLICY - MINEFUN PRO
Last Updated: October 2026
============================================================
1. INTRODUCTION
Minefun Pro ("we", "our", or "the extension") is an open client-side graphics enhancement and performance optimization utility for the online web game Minefun.io. We are fundamentally committed to protecting user privacy, ensuring transparency, and adhering to the strictest principles of data minimization and least privilege.
This Privacy Policy explains how information is handled when you use the Minefun Pro Chrome Extension.
------------------------------------------------------------
2. DATA COLLECTION & PROCESSING (ZERO DATA POLICY)
------------------------------------------------------------
• No Personal Information Collected:
Minefun Pro does NOT collect, store, transmit, monitor, or sell any personally identifiable information (PII), such as names, email addresses, passwords, IP addresses, location data, or device fingerprints.
• No Browsing Activity Tracking:
We do NOT track your browsing history, visited websites, search queries, or activity outside of the Minefun.io game canvas.
• No Analytics or Third-Party Trackers:
The extension contains ZERO external analytics scripts, advertising trackers, tracking pixels, or third-party telemetry libraries. It operates entirely offline and client-side.
• No Server Communication:
The extension does not maintain or communicate with any private backend servers or remote cloud APIs. All code and assets execute strictly within your local browser environment.
------------------------------------------------------------
3. LOCAL DATA STORAGE
------------------------------------------------------------
• What is stored:
The only data ever created or stored by Minefun Pro consists of your custom gaming visual preferences, including:
- Selected Shader Preset (e.g., Bloom, Cyberpunk, Vibrant)
- Selected Texture Filter Profile
- Display settings (Brightness, Contrast, Saturation)
- Custom Crosshair type and RGB toggle
- Performance HUD preferences (HUD position, font family, font size)
- Engine toggles (FPS Boost, Low Latency, Anti-Aliasing)
• Where it is stored:
These preferences are saved strictly on your local device using the browser's built-in `chrome.storage.local` API and `localStorage`. This data never leaves your computer and is immediately erased if you uninstall the extension or clear your browser data.
------------------------------------------------------------
4. PERMISSIONS BREAKDOWN & JUSTIFICATIONS
------------------------------------------------------------
Minefun Pro requests the absolute bare minimum set of permissions necessary to function:
1. "storage"
Purpose: Allows the extension to remember your graphics preferences, selected shaders, crosshair design, and HUD settings across browser restarts and game sessions. Without this permission, you would need to reconfigure your visual settings every time you refresh Minefun.io.
2. Host Permissions: "*://minefun.io/*" and "*://*.minefun.io/*"
Purpose: Allows the extension's content scripts to inject the real-time visual post-processing shaders, WebGL canvas hooks, custom crosshair element, and live performance HUD directly into Minefun.io pages. This permission is strictly scoped to Minefun.io domains and is inactive on all other websites.
------------------------------------------------------------
5. ARE ALL THESE PERMISSIONS STRICTLY NECESSARY?
------------------------------------------------------------
YES. Minefun Pro adheres strictly to the Principle of Least Privilege:
• Every single permission declared in `manifest.json` is indispensable for delivering the core visual and performance functionality requested by the user.
• Notice what permissions are NOT requested:
- NO `<all_urls>`: The extension has zero access to any website other than Minefun.io.
- NO `tabs`: The extension cannot inspect your open tabs, page titles, or URLs.
- NO `cookies`: The extension cannot read, write, or access your session cookies, authentication tokens, or credentials.
- NO `webRequest`: The extension cannot intercept or log network requests.
- NO `history`: The extension cannot view your browsing history.
- NO `identity`: The extension does not request access to your Google account or identity.
By strictly scoping host permissions to Minefun.io and using local storage exclusively, the extension guarantees complete security, safety, and privacy.
------------------------------------------------------------
6. THIRD-PARTY WEBSITES & SERVICES
------------------------------------------------------------
The extension operates within the context of Minefun.io. When you visit and play on Minefun.io, your interaction with that website is subject to the terms of service and privacy policy of Minefun.io. Minefun Pro does not manage or oversee Minefun.io's servers.
------------------------------------------------------------
7. CHANGES TO THIS PRIVACY POLICY
------------------------------------------------------------
We may update this Privacy Policy from time to time if new features are introduced. Any updates will continue to honor our core commitment to zero data collection and complete user privacy.
------------------------------------------------------------
8. CONTACT & SUPPORT
