Data We Collect:
To ensure the functionality and security of our website, we, through our hosting provider Hostinger, collect a limited amount of data from visitors. This includes:
- Unique IP Addresses: To identify unique visitors for analytics.
- Country of Origin: To understand the geographic distribution of our visitors.
- Total Bandwidth & Requests: To monitor server load and performance.
Basic application logs (such as error messages and security events) may also be generated when you interact with the site; these are used internally to maintain and secure the service.
How We Use Data:
The data collected is used for the legitimate interest of analyzing website traffic, improving user experience, and protecting against malicious activity. We do not use this data for marketing or to identify individuals personally beyond what is necessary for security.
Data Retention:
All analytics data, including IP addresses and request logs, is retained for a period of seven (7) days, after which it is automatically deleted from our hosting provider's servers. Unless otherwise stated in this policy, personal data is retained only for as long as necessary to provide the service or until you request deletion of your account.
Cookie Policy:
Our website uses essential and analytics cookies provided by our host, Hostinger, to perform traffic analysis. These cookies help us distinguish between visitors and ensure the stable operation of the site. By using our website, you will be asked to consent to the use of these cookies.
Local Storage and Session Storage:
We also use your browser's localStorage/sessionStorage to store session tokens and preferences needed to operate the site (for example, keeping you signed in). This data is stored on your device only, is not shared with third parties, and is cleared when you log out or clear your browser storage.
Images and Image Processing:
This site can display two kinds of profile pictures: (a) external images linked from third‑party services (e.g., VRChat) that are requested directly from those services; and (b) images you voluntarily upload to Z Tech Industrie to use as your profile picture.
- External images: When an image is loaded from a third‑party (like VRChat), your browser connects to that service and their servers may receive your IP address and user‑agent. We do not store those images on our servers and do not control how third‑parties process that data. See the third‑party’s privacy policy.
- Uploaded images: If you choose to upload a profile picture, we process it solely to display it on your account. Allowed formats are PNG/APNG or JPEG, up to 5 MB. We validate basic image properties. JPEGs are re‑encoded to normalize orientation and remove embedded metadata; PNG/APNG files are stored as provided (we do not re‑encode APNG). Filenames are anonymized; images are stored in a hardened uploads area with script execution disabled. We do not perform biometric analysis or use your images for advertising or profiling.
- Where stored: Uploaded images are stored on servers operated by our hosting provider, Hostinger International Ltd. Server location may vary (commonly within the EU/UK). We do not share uploaded images with third parties.
- Legal basis: Your consent and performance of user‑requested features (displaying your profile picture). Our legitimate interests also include maintaining the security and functionality of the service.
- Retention: Your uploaded image is kept until you delete it using the Profile Picture Editor (Delete & Reset) or until your account is removed. After deletion, the file reference is cleared and the stored file is removed from our server. Browser caches or intermediary caches may retain copies briefly; this is outside our direct control.
- Your controls: You can upload, replace, or delete your picture at any time via the Profile Picture Editor. You can also contact us to exercise access or erasure rights.
Session and Account Data:
To operate the site, we store basic account and session data associated with your holder profile, including: display name, short description, coupon number/status, chosen visual styles (e.g., coupon/pin style IDs), coin balances, and last online timestamps. Session tokens are held in your browser storage and sent to our APIs to authenticate your requests. Purpose: operate your account and features you request. Legal basis: performance of the service and our legitimate interests. Retention: until your account is removed or the data is no longer needed for operation.
Gameplay and Inventory Data (Z‑Mine and Shop):
If you use Z‑Mine or the shop, we store gameplay state and inventory necessary to provide those features, such as: fragments, lifetime fragments, upgrade levels, purchased one‑time upgrades, prestige points, permanent upgrades, coin balances, owned asset IDs, and any placement settings you save (position/size/rotation) for visual customization. Purpose: provide game and customization features. Legal basis: performance of the service and our legitimate interests. Retention: until you remove your account or request erasure; you can also reset placements in the editor.
Administrative Emails and Requests:
When you submit a coupon request or perform a redemption, our system sends internal administrative emails that may include your display name, user ID, requested coupon number, and timestamps, solely so an administrator can process the request. Recipients: internal ZTI mailboxes only. Retention: according to mailbox retention practices. Legal basis: our legitimate interests in operating the service and performing your request.
Data Sources from Public Profiles:
In some cases, administrators may upload lists of friends or contacts from external services (for example, VRChat profiles). This data may include display names, descriptions, profile picture links, and last online timestamps. Source: provided by the user/administrator, sometimes originating from publicly available information. Purpose: maintain community directories and connections. Legal basis: our legitimate interests. You may request removal of such entries at any time by contacting us.
Third-Party Data Processors and Content Delivery:
We use Hostinger as our hosting provider. Hostinger processes website analytics data on our behalf. You can view their privacy policy for more information on how they handle data.
Additionally, this website displays images that are loaded directly from the VRChat API and website. When your browser requests these images, it sends information, including your IP address, to VRChat's servers. We do not control the data collected by VRChat or their privacy practices. We recommend you review the VRChat Privacy Policy for more details.
All site data (account, gameplay, uploads, and application logs) is hosted on servers operated by Hostinger International Ltd. Server location may vary within the EU/UK.
We also link to external services such as Discord. When you follow those links, your interaction is governed by the provider’s own privacy policy (e.g., Discord Privacy Policy).
