Your personal observations.

What this preview saves

We store your session date, exercise settings, and results. Signed-in results are linked to your account identifier. Firebase Authentication manages your email and sign-in securely. Your session records are private to your account and are not shared with other players.

Guest sessions

Guest sessions are stored in this browser’s local storage for seven days. Clearing browser data removes them. Signed-in sessions are stored in your private cloud notebook; authentication tokens stay on your device until you sign out. Signing in from the same browser brings recent guest sessions into your account, unless your account already has a session for that day.

Research and subscriptions

Your sessions are not enrolled in a research study. Paid subscriptions are not active in this preview.

Your records

The notebook displays your most recent 90 completed sessions. You can download or delete your saved records below. Guest records can also be downloaded or cleared from this browser.
