Privacy Policy

Last Updated: May 2026

This Privacy Policy outlines how LifeSimGrid ('we', 'our', or 'the site') processes data. Protecting user privacy is our absolute core principle.

1. 100% Client-Side Local Processing Principle

This website operates on a 100% serverless, client-side architecture. When you upload photos, gaming avatars, or Mii QR codes for pixelation or binary decoding, every computational action — including HTML5 Canvas sampling, ArrayBuffer byte rewriting, and Web Audio API synthesis — executes entirely inside your browser sandbox in real time. We do not maintain a backend database, meaning we have zero technical capability to intercept, collect, transmit, or store your personal files.

2. Local Storage Mechanism (localStorage & IndexedDB)

The Tomodachi Voice Lab's Relationship Leaderboard saves your custom island Islander roster (up to 15 Islanders, including names, zodiac signs, and personality types) locally within your browser's localStorage under the key 'lifesimgrid-residents'. Additionally, each studio's History feature stores your recent actions (up to 20 entries per panel, including image thumbnails and configuration sliders) inside your browser's IndexedDB under the database name 'lifesimgrid-history'. Both localStorage and IndexedDB data chains remain strictly on your physical device and are never transmitted to any external server. You can instantly wipe this history at any time by clicking the 'Clear All' button inside each studio's panel or by clearing your browser's site data. No tracking cookies are deployed for these core functional utilities.

3. Cookies & Third-Party Advertising Compliance

To maintain global CDN web hosting and domain infrastructure costs, this site displays non-tracking, high-quality technology and design advertisements through premier networks such as Google AdSense, Carbon Ads, or EthicalAds. These advertising providers may deploy Cookies and Web Beacons and and comply with standard Consent Management Frameworks to aggregate non-personally identifiable technical information (such as browser type, operating system, and timestamp metrics) to optimize contextual ad relevance. You can opt out, restrict, or clear these third-party Cookies via your native browser privacy settings at any time without impacting any core tool features of LifeSimGrid.

4. Open-Source Third-Party Libraries & Telemetry

This web application integrates the following trusted open-source JavaScript libraries, all compiled to execute strictly client-side: jsQR (MIT License, QR code matrix decoding), qrcode (MIT License, QR code encoding), JSZip (MIT License, parallel local archival compression), and Lucide Icons (ISC License). None of these scripts contain outbound data hooks. Additionally, this site utilizes Google Analytics 4 (GA4) and Microsoft Clarity to track anonymous, aggregated site performance and visitor behavior metrics to help improve user experience. These diagnostic platforms may use telemetry cookies or equivalent tracking mechanisms. You can entirely block Google Analytics by downloading the official Google Analytics Opt-out Browser Add-on, or disable Microsoft Clarity through your browser's anti-tracking configurations. These web analytics integrations are entirely optional and can be blocked without affecting any tool capabilities.

5. Children's Privacy & COPPA Compliance

LifeSimGrid is a general-audience web tool and does not knowingly request or gather personal information from anyone, including children under the age of 13. Since our architecture bypasses backend storage and performs all graphics or binary processing locally, we inherently satisfy the Children's Online Privacy Protection Act (COPPA) and equivalent international safety standards. Parents can rest assured that their child's creative activity on this site leaves a zero data footprint on the internet.

6. GDPR & CCPA Regulatory Compliance

Because LifeSimGrid handles 100% of data flows within the user's browser sandbox and never collects, archives, or leaks personal identifiable information (PII), it fully complies with the General Data Protection Regulation (GDPR - European Union) and the California Consumer Privacy Act (CCPA - United States). There is no user data to access, rectify, export, or erase because we never possess it in our infrastructure. Clearing your browser's local cache permanently removes your locally managed island resident rosters and history logs.

7. End-to-End Data Security

With zero data leaving your local device, the structural risk of server-side data breaches, leaks, or cloud hacking is entirely eliminated. We are deeply committed to open-source software transparency; you can self-audit our entire front-end data flow at any time via our public GitHub repository. Furthermore, the web application is served exclusively over a secure HTTPS protocol to block any man-in-the-middle (MITM) interceptions during initial page delivery.
