When using AI through OpenRouter, whether via the chat interface or the API, your prompts and responses go through multiple touchpoints. You control how your data is handled at each step.
This page gives an overview of how your data is stored and used by OpenRouter. More information is available in the privacy policy and terms of service.
OpenRouter does not store your prompts or responses, unless you opt in to one or both of the following:
Anonymous Input Categorization: OpenRouter samples a small number of prompts for categorization to power our reporting and model ranking. If you are not opted in to OpenRouter use of inputs/outputs, any categorization of your prompts is stored completely anonymously and never associated with your account or user ID. The categorization is done by model with a zero-data-retention policy.
OpenRouter does store metadata (e.g. number of prompt and completion tokens, latency, etc) for each request. This is used to power our reporting and model ranking, and your logs metadata.
This metadata does not include the content of your prompts or responses, only information about the request itself.
