An In-Depth Investigation of Data Collection in LLM App Ecosystems

Understand

LLM app (tool) ecosystems are rapidly evolving to support sophisticated use cases that often require extensive user data collection.

• Given that LLM apps are developed by third parties and anecdotal evidence indicating inconsistent enforcement of policies by LLM platforms, sharing user data with these apps presents significant privacy risks.
• In this paper, we aim to bring transparency in data practices of LLM app ecosystems.
• We examine OpenAI's GPT app ecosystem as a case study.
