Eleven quick questions. Stored locally in your browser — never sent to a server.

Step 1 of 11 9%

Welcome

We'll ask 11 short questions about your demographics, goals, sleep, training, cognitive workload, substances, and risk tolerance. Total time: about 3 minutes.

Privacy: your answers are saved to localStorage on this browser only. We never transmit them to a server unless you explicitly opt in (and there is no opt-in yet — this is purely local).

You can edit, export, or wipe your profile anytime from the Profile page.
