Terms

Last updated 6 October 2026

Duozuo is a free translation interface. You may use the official site for personal or business conversations. Translation requests use your own OpenRouter API key and account and may incur OpenRouter charges. You are responsible for protecting your key, adding credits when needed, and setting appropriate account or key spending limits.

Duozuo does not operate an LLM. Your text is sent to OpenRouter and processed by the selected model provider under their terms and privacy policies. Review OpenRouter's Terms and Privacy Policy, as well as the applicable model provider's policies.

The optional ZDR switch is off by default. When on, Duozuo requests OpenRouter routing to a ZDR-eligible inference endpoint; a request may fail if none is available. ZDR does not keep your text on your device or govern separate OpenRouter account logging, usage metadata, or speech recognition. See our Privacy page for the detailed on/off behavior.

Automated speech recognition and translation can be wrong or unavailable. Check important details with the other person before relying on them, especially in medical, legal, financial, or safety-critical situations.

Use the service lawfully and respect other people's privacy. Do not enter information you are not authorized to send to OpenRouter and the selected model provider.

The service is provided as available, without a promise of uninterrupted access or translation accuracy. These terms govern use of the official site. The separate source license governs reuse of its code.
