Pattern51 Prompt (hereinafter "the Service") forwards user-submitted prompts to AI models to generate transformation results. This Policy explains the scope of information processed by the Service and how it is processed. The Service does not provide sign-up, login, or payment features and therefore does not directly collect personal identifiers such as name, email, or contact details.

2. Purpose of Processing
- AI-based transformation of input prompts and provision of results
