Zero Data Retention (ZDR): What It Means for AI APIs
Article image or reusable cover for OpenRouter
Zero Data Retention (ZDR) means an AI provider processes your query and returns an answer without storing either afterward.
It is a storage guarantee, but it only covers the provider's storage — not what your own systems log, not data in transit, and not third-party tools connected to the request. On OpenRouter, you can enforce ZDR at the account level, through guardrails, or with a special field in each API call. ZDR differs from "no training" (the company does not train on your data) and from region pinning (where the request is processed) — these are separate controls.
Zero Data Retention (ZDR) means an AI provider processes your prompt, returns a response, and doesn't store it afterward.
