Subprocessors

Last updated

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.

Providers listed here may support our own controller activities or processing on behalf of Customers. A provider is a Subprocessor under our DPA only to the extent it processes Personal Data on behalf of a Customer.

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.
