Zero Data Retention Search

1 post · Aug 2025

What this trail covers

Exa has implemented Zero Data Retention (ZDR) across all its search products, including search, answer, and deep research. This ensures that user query data is never stored, providing enterprise-grade data privacy. This was achieved by developing an independent search engine from scratch, avoiding reliance on third-party search providers that do not offer ZDR.

  1. Zero Data Retention across Exa Search ProductsThis post announces the extension of Zero Data Retention (ZDR) to Exa's /answer and /research endpoints, in addition to the existing ZDR search capability. It emphasizes that offering ZDR requires an independent search engine, contrasting this with providers that rely on Google. The core technical achievement is the development and operation of Exa's own search engine, which allows them to serve results without storing user query data.
