This Privacy Policy explains how Z-Image.win (“Z-Image.win”, “we”, “us”, or “our”) collects, uses, stores, and shares information when you use our website at https://z-image.win/ and any related services (collectively, the “Service”).

By accessing or using the Service, you agree to the collection and use of information in accordance with this Privacy Policy. If you do not agree with this Policy, please do not use the Service. If you have any questions, you can contact us at support@z-image.win.

1. Scope

This Privacy Policy applies to:

  • Visitors to our website https://z-image.win/
  • Registered users of Z-Image.win
  • Any use of our text-to-image and image-to-image generation tools, prompt templates, galleries, and related features

This Policy does not apply to third-party websites, services, or models that we may reference or link to.

2. How We Position Ourselves

Z-Image.win is an independent AI image-generation platform that deploys and optimizes open-source Z-Image models. We provide:

  • Our own web interface and user experience
  • Our own workflows, rate limits, and credit system
  • Our own safety policies and moderation layer

We are not an official product of any cloud provider or model vendor. All references to “Z-Image” in this Policy refer solely to our own deployment and service, not to any third-party provider.

3. Information We Collect

We follow a data minimization principle and only collect information necessary to operate and improve the Service, provide support, and comply with legal obligations.

3.1 Account Information

If you create an account, we may collect:

  • Email address
  • Password (stored using secure hashing, never in plain text)
  • Display name or profile information you voluntarily provide

Purpose: To create and maintain your account, authenticate logins, send essential service messages (such as security alerts or critical updates), and provide support.

3.2 Usage Information

We may collect limited information about how you use the Service, such as:

  • Features you use (e.g., Generate, Image-to-Image, Prompt Library)
  • Frequency and timestamps of your sessions
  • Basic interaction events (e.g., successful generations, errors)
  • High-level analytics (e.g., aggregated usage statistics)

We do not collect or inspect the textual content of your prompts for analytics by default.

Purpose: To maintain platform performance, detect abuse, debug issues, and make high-level product decisions.

3.3 Device and Technical Information

We may collect basic technical information, such as:

  • Browser type and version
  • Operating system and device type
  • IP address (used for security and fraud prevention only)
  • Referring/exit pages and general URL paths

Purpose: To ensure compatibility, enforce security controls, prevent abuse (e.g., DDoS, brute force), and derive coarse geolocation for compliance and anti-fraud measures.

3.4 Cookies and Similar Technologies

We use cookies and similar technologies to:

  • Maintain your login session
  • Remember language and UI preferences
  • Improve user experience and basic analytics

Necessary Cookies

Used to:

  • Keep you logged in
  • Protect your account and prevent fraud

These cookies are essential for the Service to function. You cannot opt-out of these without impacting core functionality.

Preference Cookies

Used to:

  • Store your language, theme, or layout choices

You may disable these via your browser settings, but some preferences may not be remembered.

Analytics Cookies (Optional)

We may use privacy-conscious analytics to understand how the Service is used in aggregate. When enabled, these cookies do not inspect or store prompt content and are configured to minimize the collection of personal data.

You can disable cookies via your browser settings. If you disable certain cookies, some features of the Service may not function properly.

3.5 Prompts and Generated Images

By default, we retain your prompts and generated images for a limited period of time so that you can view your recent history and re-use past generations.

We may store them longer only if you explicitly save them to your account (e.g. favorites, gallery, collections).

We do not use your prompts or images for model training or any other purposes beyond providing and maintaining the Service.

3.6 Payment and Billing Information

When you purchase credits or paid plans, payment information is processed by PCI-compliant third-party payment processors. We may receive:

  • Partial payment information (e.g., last 4 digits of card, card brand)
  • Transaction IDs, billing country, and tax-related metadata
  • Payment status (success, failure, refund)

We do not store full card numbers or raw payment credentials.

Purpose: To process payments, manage invoices, comply with tax and accounting obligations, and handle refunds or disputes.

4. How We Use Your Information

We use collected data for the following purposes:

  • To operate, maintain, and improve the Service
  • To authenticate user accounts and keep them secure
  • To prevent abuse, spam, and fraudulent usage
  • To respond to support inquiries and bug reports
  • To comply with legal or regulatory requirements
  • To perform high-level analytics and product planning (without inspecting prompt content by default)

4.1 What We Will Not Do

Unless you explicitly consent, we:

  • Do not sell your personal data
  • Do not use your personal data for third-party advertising
  • Do not share your prompts or generated images with external parties for their own purposes
  • Do not train models on your prompts or images

Any optional data-sharing or research programs will be clearly labeled and strictly opt-in.

5. Legal Bases for Processing (GDPR)

If you are located in the EU/EEA or a jurisdiction with similar frameworks, we rely on the following legal bases to process your personal data:

  • Contractual necessity – Providing access to the Service, including account creation, credit usage, and generation features.
  • Legitimate interests – Ensuring security, preventing abuse, improving performance, and understanding aggregate usage, in a way that respects your privacy.
  • Consent – Optional features such as saved galleries, newsletters, or any explicit opt-in data-sharing/training programs. You may withdraw consent at any time via account settings or by contacting us.

6. Sharing and Disclosure of Data

We do not sell or trade your personal information. We only share data under the following limited circumstances:

6.1 Service Providers

We may share data with trusted third-party processors who help us operate the Service, such as:

  • Cloud hosting providers
  • Payment processors
  • Logging and monitoring services
  • Email delivery services

These providers are bound by confidentiality obligations and may only process data as instructed by us.

6.2 Legal Requirements

We may disclose information if required to:

  • Comply with applicable laws or regulations
  • Respond to valid legal processes or governmental requests
  • Protect the rights, property, or safety of Z-Image.win, our users, or the public

We resist overly broad or vague requests and only comply when legally mandated.

6.3 Security and Abuse Prevention

We may share limited technical data with security or anti-fraud services to:

  • Detect and prevent fraud
  • Monitor abuse and attacks
  • Maintain platform integrity

We do not share your prompt content or generated images for these purposes, unless strictly necessary to investigate a specific abuse incident.

7. International Data Transfers

Your data may be processed in countries other than your own, potentially including locations outside the EU/EEA. When we transfer personal data internationally, we implement appropriate safeguards, which may include Standard Contractual Clauses (SCCs), data processing agreements with service providers, and industry-standard security and privacy controls.

8. Data Retention

We retain your personal data only as long as necessary for:

  • Operating your account and the Service
  • Complying with legal obligations (e.g., tax and accounting)
  • Resolving disputes
  • Ensuring security and abuse prevention

High-level guidelines include:

  • Account data: retained while your account is active, and for a reasonable period after closure.
  • Logs and security data: retained for a limited period (e.g., 30–180 days), unless needed for an ongoing investigation.
  • Saved prompts or images: retained until you delete them or close your account.
  • Ephemeral processing data: retained only as long as needed to complete generation or debug specific incidents.

You may request deletion of your personal data as described under “Your Rights”.

9. Security Measures

We implement industry-standard security controls, including encryption in transit (HTTPS/TLS), secure password hashing and salted storage, access control and least-privilege principles, and regular monitoring for abuse, anomalies, or vulnerabilities. However, no internet service can guarantee 100% security.

You are also responsible for keeping your password confidential, using a strong, unique password, and not sharing your account credentials with others. If you believe your account has been compromised, contact us immediately at support@z-image.win.

The Service is not intended for children under 13 years of age (or the age of digital consent in your jurisdiction). We do not knowingly collect personal information from children. If you believe a child has created an account or provided personal data, please contact us, and we will take steps to verify the situation and delete the account and associated data if appropriate.
