Privacy Policy
Last updated: July 2026
This policy explains what data BenchDuel collects and how we use it. By using the site you agree to this policy.
Prompts and votes
When you play a duel, we store the prompt you send and the two answers, so we can show the battle, run the rating system and improve the arena. Do not enter personal, private or sensitive information into prompts. Prompts may be publicly visible in features like recent battles.
Analytics
We collect anonymous usage data such as pages viewed, rough traffic source, device type and an anonymous session id stored in your browser. This helps us understand how the site is used. We do not require an account to use BenchDuel.
Cookies and local storage
We use local storage to keep an anonymous session id and to remember which battle you have voted on. Advertising or analytics partners may set their own cookies.
Third parties
Model answers are generated through OpenRouter, which routes requests to model providers. Your prompt text is sent to those providers to produce an answer. We may show ads from third party networks that use cookies.
Your choices
You can clear your browser storage at any time. For any data question, contact hello@benchduel.com.
