"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 β€” never sent to any server. 【What You'll Notice Right Away】 - No login to lose access to β€” no account needed, no cloud sync. Your records stay on your device - Works for irregular cycles β€” log your period whenever it comes, not when the app expects it - Predicts what matters β€” see your next period and ovulation window based on your actual patterns, not averages - Great for doctor visits β€” 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 β€” 39 languages supported, so it works wherever you are "What if I don't have regular cycles?" β€” You can log whenever your period actually arrives. No frustrating messages about being 'irregular.' "Is my data safe?" β€” 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?" β€” It means the app you used wasn't built for you. Luna Cycle records whenever your period actually arrives β€” no 'irregular' label, no frustrated messages. Your cycle is your normal. "I'm on the pill. Is a period tracker even useful for me?" β€” 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. Privacy Policy: https://luna-cycle-prod.web.app/privacy.html Terms of Use: https://luna-cycle-prod.web.app/terms.html Download free β€” your data stays yours.
