Privacy Policy

Overview

This privacy policy describes how the ModelHub Image Generation plugin (hereinafter referred to as "the Plugin") handles user data when generating images using the nanobanana model via ModelHub.

Data Collection

The Plugin collects the following types of data:

1. Text Prompts: User-provided text descriptions used to generate images
2. Input Images (optional): Images provided by users in URL or base64 format for image-to-image generation
3. API Credentials: API Key required to access the ModelHub service (stored securely using PKCS1 OAEP encryption)
4. Generation Parameters: Image size (1K, 2K, 4K) and aspect ratio (1:1, 9:16, 16:9) preferences

Data Transmission

All data collected by the Plugin is transmitted to the third-party service api.easyart.cc (ModelHub API) for image generation processing. This includes:

• Text prompts and generation parameters
• Input images (if provided)
• API authentication credentials

Data Storage

• API Key: Stored securely in Dify's credential system using PKCS1 OAEP encryption technology
• Generated Images: Returned to users through the Dify workflow and may be stored according to Dify's file storage policies
• User Input Data: Not permanently stored by the Plugin itself; data is only transmitted to the API service for processing

Third-Party Services

The Plugin relies on the following third-party service:

• ModelHub API (api.easyart.cc): Handles image generation requests using the nanobanana model. Users must obtain an API Key from https://api.easyart.cc/register?aff=Uimc to use this Plugin.

Users are subject to ModelHub's own privacy policy and terms of service when using their API.

Data Usage

Collected data is used solely for:

• Processing image generation requests
• Authenticating API access
• Returning generated images to users

Data Security

• API Keys are encrypted using PKCS1 OAEP encryption before storage
• Data transmission occurs over HTTPS connections
• The Plugin does not log or store user prompts or images beyond what is necessary for API processing

User Rights

Users have the right to:

• Access and modify their API credentials through Dify's plugin settings
• Stop using the Plugin at any time
• Request deletion of stored credentials

Changes to This Policy

This privacy policy may be updated periodically. Users will be notified of significant changes through the Plugin's update mechanism.
