Operational clarifications
Frequently asked
No. These utilities produce structured operational estimates of invisible internal load. They are not medical, psychiatric, or diagnostic instruments.
Is this a medical or diagnostic tool?
No. These utilities produce structured operational estimates of invisible internal load. They are not medical, psychiatric, or diagnostic instruments.
What does the readout actually represent?
A pattern-level estimate based on the inputs provided — useful at the resolution it offers, silent beyond it. It is not a measurement of an underlying state.
How often should I use it?
As often as it is operationally useful. There is no daily streak, no scoring, and no progress to maintain. The utility is the readout itself.
Are inputs stored or shared?
Inputs are processed locally to produce the estimate. No personal data is required to use the utility.
