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】

- Your data can't disappear — no account needed, no cloud sync. Your records survive phone changes, app updates, everything
- No ads, no upsell popups — open the app and just use it. No "upgrade to premium" interruptions every time
- 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
- Women tired of ad-heavy, subscription-pushing apps
- 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.

"I paid for premium in another app and it still showed ads." — Luna Cycle's basic features are free — and there are no upsell pop-ups every time you open it. If you upgrade, you get what you paid for.

People say things like: "I lost 3 years of data when my old app shut down. This is the first tracker I trust — it stays on my device." "Finally a period app that doesn't push premium at me every single time I open it." "My cycles are irregular and every other app made me feel broken. This one just lets me log when it comes."

【Premium Subscription】

All basic tracking is free. Premium unlocks advanced insights and trend analysis. Subscription renews automatically unless canceled 24 hours before renewal. Managed in Apple ID Account Settings.
