Prompt data flows to multiple AI providers with independent and varying data policies — users must independently verify each routed provider's training and retention practices. Opt-in logging grants an extremely broad irrevocable commercial license including sublicensing and potential data sales in anonymized form. Complex multi-provider sovereignty risk.
Do not enable 'OpenRouter Use of Inputs/Outputs' opt-in for sensitive use cases. Enable ZDR (Zero Data Retention) routing mode. Review the specific provider being used for each model — check openrouter.ai/docs for provider-specific data retention policies. Consider the trust center for compliance documentation. For sensitive workloads, use API directly with providers that have contractual DPAs.
