Anthropic's Privacy Promise Has a September 2025 Expiration Date

Anthropic's original privacy commitment was not a footnote — it was a market positioning statement. While OpenAI defaulted to training on conversations and Google Gemini integrated chat history with broader account data, Anthropic held a clear line: your conversations would not be used to train Claude. That line was cited in developer documentation, referenced in procurement discussions, and treated as a durable feature by the researchers and practitioners who chose Claude over competitors on privacy grounds.
