Your cycle, your data, your device. Full Moon Flow is a simple, private period tracker that keeps all your data on your device. No accounts, no cloud sync, no tracking. Just open the app, tap a day, and log your flow. What it does: • Log your daily flow intensity (spotting, light, medium, heavy) on a clean monthly calendar • Log your mood if desired, track patterns over time to see how your cycle affects your mood. • See your cycle history at a glance- period duration and cycle length for each past cycle • View averages and trends- know your typical cycle length and how it's changing over time • Get a gentle estimate of when your next period might start, based on your own history • Export your data as a CSV file anytime. It's your data, you control it. What it doesn't do: • No accounts to create • No data sent to any server ever • No ads, no analytics, no tracking • No fertility or ovulation predictions • No notifications (yet) Privacy first. Full Moon Flow was designed from the ground up to keep your menstrual health data completely private. Everything is stored locally on your device in an encrypted database. Nothing is transmitted over the internet. When you delete the app, your data is gone, because it was never anywhere else. Simple by design. No cluttered dashboards, no gamification, no social features. Just a calm, clean interface that helps you understand your cycle without the noise.
