1. About the Developer & Publisher (joy hosen)
joy hosen is an independent game developer, 3D level architect, and software publisher dedicated to building responsive, high-framerate PC games that combine modern 3D visual polish with ultra-lightweight installation sizes. Every character animation, procedural parkour module, 3D spike trap, brilliant-cut diamond shader, and interactive lobby stage in ZephRun has been custom-engineered by joy hosen.
2. Custom Procedural Engine & Technical Architecture
Unlike traditional platformers that repeat the same static maps or require tens of gigabytes of storage, ZephRun uses real-time mathematical geometry, procedural checker surface texturing, and Web Audio API sound synthesis. This allows the game to generate an infinite number of unique 3D parkour courses on the fly while running smoothly at 60+ FPS on both budget laptops and dedicated gaming PCs.
3. Quality Assurance & Player-First Commitment
- 100% Earned In-Game Economy (Zero Real-Money Gambling): Every Royal Coin, Brilliant Diamond, and 1,000,000-Coin Lobby UI Design in ZephRun is earned purely through gameplay skill and parkour exploration—there are no pay-to-win microtransactions or loot boxes.
- Hardware Scalability: Built-in Graphics Presets (Low, Medium, High) and adjustable Mouse Sensitivity allow players to tailor shadow resolution, pixel ratio, and 3D cloud density to their exact hardware.
- Direct Developer Support: Players and storefront reviewers can reach joy hosen directly at dared0863@gmail.com for technical assistance, bug reports, or verification inquiries.
🔒 Comprehensive Privacy Policy & Data Usage Guide
Last Updated & Effective Date: October 29, 2026
This Privacy Policy explains how ZephRun - 3D Parkour Odyssey ("ZephRun", "the Game") and its official website operated by joy hosen ("Developer", "Publisher", "we", "us", or "our") handle user data, local save files, and system permissions. This document is designed to meet all transparency requirements for PC digital storefronts, including the Epic Games Store.
🛡️ Summary: Zero Personal Data Collection & 100% Local Save Privacy
ZephRun does NOT collect, track, store, or transmit any personal data, identity information, IP addresses, or telemetry to any external server. All game progress, unlocked levels, coins, diamonds, and settings are stored 100% locally on your own computer.
1. Personal Data Collection Policy (What We Do NOT Collect)
When you download, install, and play ZephRun on your computer, the application operates strictly as an offline-capable single-player game. Specifically, the game:
- Does NOT collect personal identifiers: We never ask for, read, or transmit your real name, home address, phone number, email address, or government ID inside the game.
- Does NOT track hardware or network data: We do not log your IP address, MAC address, GPS location, browser history, or hardware serial numbers.
- Does NOT access sensitive peripherals: ZephRun never requests permission to use your webcam, microphone, contacts, or personal hard drive folders (such as Documents, Pictures, or Desktop).
- Contains ZERO third-party advertising or analytics SDKs: There are no hidden tracking pixels, behavioral ad networks, or third-party data brokers embedded inside the game code.
2. How Game Data & Progress Are Saved and Used (Local Storage Architecture)
To provide a seamless campaign experience where you can close the game or shut down your PC and resume from the exact level you reached later, ZephRun uses your device's built-in sandboxed local storage (`localStorage` key: `zephrun_final_save_v5`). Here is the exact technical breakdown of what is saved locally on your machine and how it is used:
- Campaign Level Progression (`unlockedLevel`, `completedCount`, `lastPlayedLevel`): Used solely by the game client to remember the highest level you have unlocked (whether Level 5, Level 50, or Level 1,000+) so the Lobby's "CONTINUE LEVEL" button and Level Progression Grid load your exact stage automatically.
- In-Game Wallet Balances (`walletPoints`, `walletCoins`, `walletDiamonds`): Used locally to keep track of the Royal Crown Coins and Brilliant Diamonds you collect during parkour courses and convert in the Store.
- Store Unlocks & Active Lobby Theme (`ownedDesigns`, `equippedDesign`): Remembers which of the 8 Lobby UI & 3D Stage Designs (from Cyber Default up to Omega Astral Emperor) you have unlocked and applied.
- High Scores & Best Diamonds (`highScores`, `bestDiamonds`): Displays your personal best score and diamond count (out of 3) on each level card.
- User Preferences (`graphics`, `sensitivity`): Remembers your chosen Graphics Preset (`LOW`, `MEDIUM`, or `HIGH`) and Mouse Sensitivity slider value (`40%` to `180%`) so you do not have to reconfigure them every time you launch the game.
3. Full User Control Over Saved Data (One-Click Reset)
Because all gameplay data resides exclusively on your computer, you have complete ownership and control over it at all times:
- In-Game Data Reset: You can open the Lobby Settings menu at any time and click the "Reset Data" button. This immediately erases all saved level progress, coins, diamonds, high scores, and unlocked lobbies, restoring the game to a fresh Level 1 state.
- Uninstallation Cleanup: Uninstalling the game or clearing application storage removes all local save data from your device.
4. How "ZephRun" Runs Safely on Your PC
- Sandboxed Execution: ZephRun runs inside a secure, isolated desktop window. It does not modify your Windows Registry, system boot configuration, or background services.
- Synthesized Web Audio: All sound effects (jumps, double-jump flips, air dashes, coin chimes, diamond pickups, and background music) are synthesized mathematically in memory via the Web Audio API.
- Zero Real-Money Financial Risk: Although ZephRun features an in-game Store with a Diamond-to-Coin converter and Lobby UI themes priced up to 1,000,000 Coins, all currencies are 100% virtual and earned exclusively through gameplay. The game never asks for credit cards, bank accounts, or real-world payments.
5. Website Contact Support Form Data
If you voluntarily use the "Send a Direct Message" form on the Contact Support tab of this website:
- You provide your Name, Email Address, Subject, and Message so that your inquiry can be routed to our official support inbox (dared0863@gmail.com).

6. Third-Party Distribution Platforms (Epic Games Store)
When you download, launch, or update ZephRun through a digital storefront such as the Epic Games Store, that platform may process standard account information (such as library ownership or download logs) under its own independent Privacy Policy.
7. Children's Privacy (COPPA & Global Compliance)
ZephRun is a family-friendly 3D parkour platformer and does not collect personal information from anyone, including children under the age of 13. If a parent or guardian believes their child has submitted personal details through our website's email support form, please contact us at dared0863@gmail.com and we will permanently delete that message immediately.
