PRIVACY POLICY & PERMISSION DISCLOSURE
Extension: HappyMod - Ultra Hack for MooMoo.io
Version: 2.1.0
Last Updated: October 2026
--------------------------------------------------------------------------------
1. INTRODUCTION
--------------------------------------------------------------------------------
HappyMod Ultra Hack ("we", "our", or "the extension") values and respects your privacy. This Privacy Policy details the exact nature of permissions requested, data handling practices, and our commitment to transparency and security.
HappyMod Ultra Hack is designed from the ground up as a client-side gaming enhancement tool. We do NOT collect, transmit, store, sell, or monetize any of your personal data or browsing activity.
--------------------------------------------------------------------------------
2. DATA COLLECTION & HANDLING: STRICT ZERO-DATA POLICY
--------------------------------------------------------------------------------
• No Personal Information Collected: The extension never collects names, email addresses, IP addresses, location data, or contact details.
• No Browsing History Tracked: The extension only runs on MooMoo.io domains and cannot observe, track, or record your activities on any other website.
• No Keystroke Logging or Credential Harvesting: Key events are processed locally solely to trigger in-game actions (such as auto-gather or opening the in-game menu). No keystrokes are recorded or transmitted anywhere.
• No External Tracking / Analytics: There are no third-party analytics (e.g. Google Analytics, Mixpanel, or Facebook Pixel) embedded inside this extension.
• 100% Client-Side Operation: All game calculations, pathfinding, and HUD rendering occur entirely within your local browser sandbox.
--------------------------------------------------------------------------------
3. DETAILED PERMISSIONS DISCLOSURE
--------------------------------------------------------------------------------
To function correctly, the extension requests only two minimal permissions:
A. "storage"
• Why it is needed: Allows the extension to remember your customized settings between browser restarts (e.g. whether Auto-Placer is active, your preferred visual HUD theme, audio volume, and combat toggles).
• Where data is stored: Saved strictly on your computer using Chrome's local storage API (`chrome.storage.local`). It never leaves your machine.
B. Host Permissions: "*://*.moomoo.io/*", "*://moomoo.io/*"
• Why it is needed: Necessary to inject the client-side user interface (custom HUD, radar display, in-game menu) and assist the player during active gameplay on MooMoo.io and its sandbox servers.
• Scope: Strictly limited to MooMoo.io domains. The extension has zero access to search engines, social networks, banking websites, or any other web pages.
--------------------------------------------------------------------------------
4. ARE ALL THESE PERMISSIONS STRICTLY NECESSARY?
--------------------------------------------------------------------------------
YES. Both requested permissions represent the absolute minimum required under Chrome Web Store's Principle of Least Privilege:
1. Could we remove "storage"?
Without the "storage" permission, your custom settings, enabled cheats/toggles, and theme selections would be wiped every time you close the tab, requiring you to reconfigure the entire mod before every match. "storage" is strictly confined to your device.
2. Could we reduce Host Permissions?
We have already restricted host permissions strictly to MooMoo.io domains (`*://*.moomoo.io/*`). We purposely DO NOT request broad permissions such as `<all_urls>` or `http://*/*`. The extension is physically blocked by Chrome from running on any domain other than MooMoo.io.
3. Unnecessary permissions explicitly avoided:
• We do NOT request the "tabs" permission.
• We do NOT request the "webRequest" permission.
• We do NOT request the "cookies" permission.
• We do NOT request the "management" or "nativeMessaging" permissions.
• We do NOT load any remote JavaScript code from external servers (fully compliant with Manifest V3 security rules).
In summary, every permission requested is directly tied to core user-facing functionality and cannot be reduced any further without breaking the extension.
--------------------------------------------------------------------------------
5. DATA RETENTION & DELETION
--------------------------------------------------------------------------------
All stored preferences reside exclusively in your browser's local cache. If you uninstall the extension or clear your browser data, all stored preferences are permanently and immediately erased from your system.
--------------------------------------------------------------------------------
6. CHANGES TO THIS POLICY
--------------------------------------------------------------------------------
If any updates are made to the extension that alter permission requirements or features, this Privacy Policy will be revised accordingly.
