4. Data Storage and Processing
4.1 Cloud Processing
About AI Processing
The App's AI features are processed in the cloud using Google Vertex AI (Gemini API). Our server does not permanently store conversation data. Additionally, data caching on the Vertex AI side has been disabled, so processed data is not cached by Google. However, Google may retain logs for a limited period for abuse detection purposes.
Data is transmitted through encrypted communication (HTTPS). For details on how Google Vertex AI handles data, please refer to the Google Cloud Service Terms.
4.2 AI Model Training
Your Data Is Not Used for AI Training
Your conversation data is never used to train or improve AI models. Data is used solely for generating replies and analysis, and is discarded immediately after processing.
4.3 Local Data
Conversation history and settings within the App are stored on your device. You can lock the App with Face ID or Touch ID to prevent unauthorized access.
If you use the feature to save analysis results as images, you will need to grant write access to your photo library. The App does not read the contents of your photo library.

Data flow: Your device → Our server (Cloudflare, global edge network) → Google Vertex AI (cloud processing) → Response returned to your device
All data transfers are protected by HTTPS encryption. We have configured Google Vertex AI to disable data caching and logging to minimize data retention during transfers.
