Your audit trail: every prompt you run is logged here with the model that answered, the HAL verdict, and the resulting RepIDchange. This table is stored in this browser's IndexedDB and nowhere else — no server-side copy, unencrypted, erased if you clear site data. Export it any time.
To be exact about what that does notmean: running a prompt sends it to our router and on to the model provider that answers it, and scoring happens on our server. We retain a 200-character prompt preview for routing quality — never the full prompt or answer. The privacy property here is “your history is yours”, not “nothing left your machine”.
