## What is Fertility Window Planner?

Fertility Window Planner is the calm, private way to find your fertile window while trying to conceive. No ads, no data selling, no AI chatbot — just your own signs, read by a transparent engine that shows its work.

LOG YOUR SIGNS IN SECONDS
Record basal body temperature (°F or °C), cervical mucus, ovulation-test results, flow, intercourse and symptoms — one tap per day, editable any time.

SEE YOUR FERTILE WINDOW
The Dawn Arc and a phase-tinted calendar show the six days you're most likely to conceive, your predicted ovulation day, and your next period — each with an honest confidence tier.

UNDERSTAND THE 'WHY'
A BBT chart draws your temperature curve with the computed coverline, the shaded fertile window and your mucus/OPK markers — so you can see exactly how each prediction was made. Nothing leaves your device to compute it.

BUILT FOR PRIVACY
Your data is yours: protected by per-account security, never sold, no third-party trackers. Export or delete everything any time.

PRO (optional subscription)
Unlock full cycle history, cross-cycle chart overlay, personal pattern insights and saved summaries. Core logging and your current fertile-window prediction are always free.
- Monthly $6.99 or Annual $39.99, with a 7-day free trial
- Payment is charged to your Apple ID at confirmation; auto-renews unless canceled at least 24 hours before the period ends; manage or cancel in Settings

Fertility Window Planner is for general wellness and body literacy. It is not medical advice, a diagnosis, or a contraceptive method, and never labels days 'safe' or 'unsafe.' Talk to a healthcare provider about conceiving or any concern.
