No. FlowLuna is a reflective tracking tool — it isn't a contraceptive, fertility treatment, or diagnostic device. Predictions are informational only. For medical decisions, please speak with a clinician.
Yes. From the Report page you can print or save a doctor-ready PDF summary of your last 6 months — period starts, cycle lengths, and most-frequent symptoms.
Yes. FlowLuna averages your last few cycles instead of assuming a fixed 28-day length, and it labels predictions as estimates until it has enough data to be confident.
Accuracy improves as you log more period starts. Until then, predictions use your stated cycle length. The fertile window is an estimate, not a diagnosis — don't rely on it for contraception.
Luna receives a short summary of your current phase, recent symptoms, and moods to write a gentle daily reflection. It does not see your free-form notes, and it never receives anything outside that context.
Yes. You can download the report PDF at any time, and the Settings page lets you wipe every log and prediction. Deletion is permanent and immediate.
FlowLuna's core tracking, predictions, and reports are free. Future advanced features may be paid, but anything you've logged will always remain accessible and exportable.
It anchors the cycle math — phase, fertile window, and next-period estimate — so you see meaningful predictions on day one instead of waiting a full cycle.
