Add two cycle reminders through the existing notification cascade and the
honest self-hosting privacy framing for reproductive-health data.
Notifications:
- New event types CYCLE_PERIOD_SOON (fires ~2 days before the predicted
next-period start, from the cached prediction) and CYCLE_PERIOD_CONFIRM
(a gentle "did your period start?" on/after the predicted start while no
period is logged, within a short grace window). Both default OFF and are
gated again on cycleTrackingEnabled — opt in twice for a sensitive surface.
- A 15-minute pg-boss cron mirrors the mood-reminder worker: it scans users
with cycle tracking enabled + predictionEnabled, computes who is in-window
from the cached forecast, and dispatches one push per event per local day.
Idempotency anchors on the push_attempts ledger (no new table). The queue
is declared, registered in allQueues, scheduled, and wired to a boss.work
handler, with a source-grep guard so it cannot ship unregistered.
- Honours notificationPrefs.cycle.clientManaged (skip the server push when
the device owns local reminders, with a suppressed annotation, mirroring
the medication path) and CycleProfile.discreetNotifications (generic
"HealthLog reminder" body so no cycle event is named on the lock screen).
- Every attempt is recorded in push_attempts via the unchanged dispatcher.
Privacy / disclaimer:
- docs/self-hosting/reproductive-health-data.md — the "no cloud vendor to
subpoena" framing with the honest residual-threat caveat (your own host,
provider, backups, and devices remain part of the surface), citing the
2021 FTC settlement and 2025 verdict as public record only.
- docs/security/cycle-data-threat-model.md — a compact "protects against /
does not protect against" note, plus README pointers.
- CyclePredictionDisclaimer component (reusing the GLP-1 estimate-disclaimer
pattern) for every fertility/prediction surface: descriptive, not a
contraceptive method, not medical advice, never a safe-to-have-unprotected
-sex claim. 6-locale copy under cycle.disclaimer.
