https://duckduckgo.com/aichat/privacy-terms"We do not save or store your Prompts or Outputs.
Additionally, all metadata that contains personal information (for example, your IP address) is obfuscated from underlying model providers (for example, OpenAI, Anthropic).
If you submit personal information in your Prompts, it may be reproduced in the Outputs, but no one can tell whether it was you personally submitting the Prompts or someone else.
We have agreements with model providers to further protect your privacy.
As noted above, we call model providers on your behalf so your personal information (for example, IP address) is not exposed to them. In addition, we have agreements in place with all model providers that further limit how they can use data from these anonymous requests that includes not using Prompts and Outputs to develop or improve their models as well as deleting all information received within 30 days."
