## What is Sync?

Be the partner she didn't have to ask for.

Sync is built for the partner — not the tracker. If someone you love has a menstrual cycle, is pregnant, or is recovering from birth, Sync helps you understand what her body is going through and how to actually show up for her. It teaches you. It never tracks her.

WHAT SYNC DOES
• A clear, cited explainer for all four cycle phases — the physiology, what's commonly felt, and concrete things you can do to help.
• A 52-week postpartum companion grounded in ACOG, WHO, and peer-reviewed sources, with a red-flag guide for when to call a doctor now.
• A sleep-deprivation survival kit for the newborn months.
• Optional, read-only calendar sync (Pro) and an opt-in paired-device mode (Plus) that she controls completely.

WHAT SYNC DOES NOT DO
• It does not track or predict her cycle. Her own app already does that.
• It is not a fertility tracker and not a contraceptive method.
• It never accesses HealthKit, location, contacts, or photos.

Sync is educational only. It is not a medical device, not a diagnostic tool, not a fertility tracker, and not a contraceptive method. Consult an OB-GYN or qualified clinician for medical questions. In an emergency, call your local emergency number.

PLANS
• Free: the four-phase basics + the first postpartum week.
• Pro ($4.99/mo or $29/yr): the full cited education, 52-week postpartum guide, read-only shared calendar, and the Today's Phase widget. 7-day free trial.
• Plus ($7.99/mo or $49/yr): everything in Pro, plus an opt-in paired-device companion (she controls every share, either side can stop instantly) and on-device suggestions. 14-day free trial. Family Sharing for two.

PRIVACY
Sync collects nothing. Everything you enter stays on your device. There is no account, no backend, and no tracking. The optional paired zone uses Apple's end-to-end-encrypted CloudKit and can be severed by either person at any time.

Built with respect — for her, and for you.
