What the app never says
A short list, because it is the reason several things in the app look plainer than they might.
About your cycles
No label is ever applied to them. Not late, not irregular, not abnormal — and not the flattering ones either, because “your cycles are regular” is the same kind of verdict. You get the number of days and your own range.
About conception
Nothing. No fertile window, no best days, no prediction, no comment on a home test reading. The app's standing line says it is not for contraception. It appears on the welcome screen, twice in Settings, on How we count, in the glossary, on Just diagnosed, under the guideline band on Cycle lengths, and — in short form — at the foot of every summary PDF.
About your body
No diagnosis, no risk score, no interpretation of a lab result as high or low. The laboratory's own range is shown; the reading belongs to your clinician. Nothing the app counts is ever turned into a statement about you — the glossary does explain what a term means and how common something is, with the source named, but that is a definition, not a finding about your log.
About what to do
No advice on food, weight, exercise or supplements. No cycle syncing. No “time to increase the dose”. The app holds what happened; decisions are between you and your clinician.
About how you are doing
No streaks, no scores, no percentage of anything filled in, no congratulations, and nothing at all when you do not open it for a week.
Why
Two reasons, and both are practical. An app that interprets health data starts to look like a medical device, with everything that follows. And a verdict from software is worth less than nothing to someone whose experience has already been dismissed by people — which, in the stories this app was built from, is most of them.
