Privacy

Big Brain Test does not ask you to create an account. You can play without signing in.

On this device we save your latest score, which answers you missed, and how many of your two runs you have used, so the 12-hour pause can start after the second finish. A quiz in progress is kept for this tab only, so a refresh does not wipe the clock.

When you finish, the numeric score is sent to our server to update an anonymous median. We do not attach your name, your answers, or a device identifier to that number.

If a writing model is available, your score and title are sent once to write a single friendly sentence. That sentence is saved on this device with your result. We do not keep a copy of it on the server.

We do not sell your information. The quiz is for entertainment only and is not a clinical test.
