Subprocessors - PromptEden

Yulan Ventures, LLC, doing business as PromptEden ("PromptEden," "we," "us") uses the following third-party subprocessors to deliver, secure, and improve our AI agent for AEO: research, content generation, publishing, and AI search visibility monitoring. We update this page when subprocessors are added or removed. If you have a Data Processing Agreement (DPA) with us that includes subprocessor change notifications, we will notify you per the terms of that agreement.

We transmit prompt content, workspace content you provide or approve for research and content generation, locale hints, and model parameters. We never transmit account credentials or billing data to AI model providers.
