Store description excerpt
Cylune is a beautifully simple period calendar that keeps your cycle information on your device. Cylune works entirely offline, without ads, accounts, tracking, cloud storage, or external services. It is thoughtfully created with enduring care for women and deep respect for their privacy. View and edit all periods in one calendar. Tap any day to select it—and tap again to remove it.
