Life-stage modes
A cycle tracker that assumes every month is the same kind of month is wrong three or four times a decade. A profile's life-stage mode tells lunarlog what to compute and show — and switching is free, reversible, and never touches what you logged.
The five modes
Every profile runs in exactly one of five modes, set from the profile editor:
- Period Tracking — the default: cycles, flow, symptoms, and the estimates built from them.
- Conceive — adds an estimated fertile window and a daily-chance reading, each framed with the research behind it.
- Pregnancy — pauses the period estimate and counts by week from an estimated due date.
- Perimenopause — pauses the period estimate while cycles are still logged and kept.
- Postpartum — pauses the period estimate and counts the days of postpartum, with a gentle offer to log when a first bleed arrives.
Switching never rewrites your history
Changing modes changes what the app computes and displays — nothing else. Entries, symptoms, tags, and notes are all kept exactly as they were, every switch recomputes estimates from the same history, and you can switch back whenever life changes again.
How the modes read
In Conceive mode, the fertile window is an estimate derived from the profile's own logged history, and the daily-chance figure arrives with its source study named in the app. It is information, not medical advice — and it must not be used to prevent pregnancy. Pregnancy, Perimenopause, and Postpartum modes say openly that the period estimate is paused, instead of silently showing a stale prediction.
Who is reading also matters
Modes change what is computed; separately, a profile's reading level — standard, teen, or supported care framing — changes the vocabulary the app uses with whoever is reading. The two axes compose: a teen profile in Period Tracking mode, or an adult profile in Perimenopause mode with a caregiver alongside. A teen profile's reader level is suggested once, never forced.
