Privacy Policy

Shodo Brush

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

1. Information We Collect

Information You Provide (Stored On-Device)

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

• The mood/goal description text you enter
• The AI-generated match result (phrase name, explanation) and your match history

Sending Data to AI

To provide the matching feature, the App sends the mood/goal text you enter to Anthropic's Claude API, which generates the shodo phrase match. The submitted content is used only to process that matching 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.
