Luna Cycle – Period Tracker

"I lost years of period data because I couldn't log in anymore."

That's the most common complaint about popular period trackers. Luna Cycle is built differently. Your data stays 100% on your device — never sent to any server.

【What You'll Notice Right Away】

- No login to lose access to — no account needed, no cloud sync. Your records stay on your device
- Works for irregular cycles — log your period whenever it comes, not when the app expects it
- Predicts what matters — see your next period and ovulation window based on your actual patterns, not averages
- Great for doctor visits — bring your detailed log to your next gynecology appointment

【Perfect For】

- Anyone who's lost period data before and never wants that to happen again
- Those managing irregular cycles, pill schedules, or hormonal treatments
- Privacy-conscious users who don't want intimate health data in the cloud
- Travelers — 39 languages supported, so it works wherever you are

"What if I don't have regular cycles?" — You can log whenever your period actually arrives. No frustrating messages about being 'irregular.'

"Is my data safe?" — Everything stays on your device. We have no server to hack, no database to breach.

"I've been told my cycle is irregular for years. Does that mean I can't use a period tracker?" — It means the app you used wasn't built for you. Luna Cycle records whenever your period actually arrives — no 'irregular' label, no frustrated messages. Your cycle is your normal.

"I'm on the pill. Is a period tracker even useful for me?" — Yes. Logging your pill schedule, skip weeks, and withdrawal bleeds gives you a clear record to bring to your OB-GYN. It turns a routine appointment into a useful conversation.

【Premium Subscription】

All basic tracking is free. Premium adds a passcode lock (Face ID or passcode) and removes ads. Subscription renews automatically unless canceled 24 hours before renewal. Managed in Apple ID Account Settings.
