LMArena

Arena has historically released conversation datasets publicly; the policy's research clause covers that.

“We may use your personal information (such as your votes and prompts) for research and other similar purposes (for example, publishing research-related materials and developing insights into the Service and AI technologies in general). / Arena uses large language models, text-to-image models, and other AI technologies from third parties that employ software code to operate the user input/prompt features that you can use to submit your prompts, images, and other data through the Service.”

“You can ask us to delete the Personal Information that we have collected from you.”

“We are headquartered in the United States and may use service providers that operate in other countries. / Your personal information may be transferred to the United States or other locations where privacy laws may not be as protective as those in your state, province, or country.”
