Karesansui Zen

SEADICE ("we", "us", "our") sets out this Privacy Policy regarding the handling of personal information in the iOS app "Karesansui Zen" (the "App").

1. Information We Collect

Information You Provide (Stored On-Device)

The App uses the free-text mood description that you enter to generate a karesansui layout. This information is stored, together with the generated layout, only on your device (via local app storage) and is not permanently stored on our servers.

• The mood description text you enter
• The AI-generated layout result (rock grouping, raking pattern, explanation) and your generation history

Sending Data to AI

To provide the generation feature, the App sends the mood text you enter to Anthropic's Claude API, which generates the karesansui layout. The submitted content is used only to process that generation request and is not permanently stored on our servers. Please refer to Anthropic's Privacy Policy for how they handle data sent to their API.
