Usage & termsDaily and file limitsPDF uploads range from 15 to 50 pages by plan
Provider privacy varies by model; uploads go through a separate content moderation service.
Optional Sync & Backup stores encrypted chat history on DuckDuckGo servers.
Separate the request from identifying metadata
DuckDuckGo removes identifying metadata, such as the IP address, before sending a request to the model provider. Its agreements prohibit using conversations for model training; an author can choose this route when discussing unpublished material.
The provider still processes the prompt unless the selected model has zero-provider visibility. The general privacy terms allow retention up to thirty days, with limited safety and legal exceptions; stronger protections depend on the chosen model.
Choose a model with zero-provider visibility
Selected models hosted by Tinfoil run in a trusted execution environment that, according to DuckDuckGo’s documentation, prevents the host from seeing prompts or responses. They are labeled zero-provider visibility in the model choice.
This protection belongs to those models. Uploaded images and files still go to a separate moderation service outside that encrypted channel.
