On this thread in Reddit:

u/JungianJester asked whether voting on responses sends the results to Anthropic (or any remote service, for that matter). I clarified that it does not:

No.

The evaluation feature is designed to have you understand how each model works for you (technically, for your organization). The evaluation data is kept locally. You can go into the settings and see how different models rank against each other based on the feedback you provide during your chats.

This is meant to help you select the best model for the best use cases.

u/productboy also asked how local storage worked. To which I responded:

The data is stored inside the Docker container at location /app/backend/data.

Depending on how you start the Docker container, let’s say docker run --volume=open-webui:/app/backend/data..., that folder is mounted to the location in your computer where open-webui lives (this varies across systems).

You can switch the volume flag to a more specific directory like -v ~/open-webui-data:/app/backend/data and then all you have to do is go into that folder to see the data saved/used by Open WebUI
