Menstrual phase dosing is the optional logging context inside Unfair that lets a user tag a daily log with a self-reported menstrual cycle phase so later review can group adherence, side effect notes, and outcome proxies by phase.
Why this is a logging context, not a protocol
Unfair does not predict cycle phases, infer hormones, or recommend cycle-driven dose changes. The phase label is metadata that the user supplies. Treating it as metadata keeps the responsibility for medical decisions with the user and their clinician while still giving the user a way to ask structured questions later.
What the label is meant to support
Some users notice recurring patterns across a cycle in mood, sleep, gastrointestinal comfort, and energy. When that context is invisible to a stack journal, week-to-week comparisons can mix signal with normal cycle variation. The phase tag gives review screens a way to align entries that share a similar background state, which is especially useful when the user is reading their own adherence history alongside daily side effect note entries. The complete supplement stacks guide covers how context tags fit beside dose windows and review cadence.
What gets stored
A typical entry stores the user-selected phase label, the entry timestamp, and any voluntary symptom or mood scores. The app does not derive ovulation timing or hormonal levels from this label. The label is opt-in and is not required for the rest of Unfair to work.
How review screens use the tag
After a few cycles of data, a phase-grouped review can show whether a particular dose window and a particular side effect note line up only inside one phase or whether they appear evenly. A pattern that is concentrated in one phase is a candidate observation to share with a clinician, not a license to self-adjust.
Privacy posture
Cycle logs are sensitive. Unfair treats them as health-context entries and surfaces them inside the user's own review screens.
How this appears in Unfair
A small optional phase chip can be attached to a day log. Review screens can group entries by phase. No automated dose change is triggered by this tag.
Clinical safety note
Menstrual phase dosing is not medical guidance. New, painful, or unusual cycle changes are a clinician consult conversation rather than a self-directed stack change.
