LunaLock
Private Period Tracker
Free · In-App Purchases · Designed for iPad. Not verified for macOS.
Track your period with zero cloud sync. 100% local data, FaceID lock, and smart cycle prediction. Privacy first, always.
LunaLock is the period tracker that actually keeps your data private. No cloud sync. No accounts. No data collection. Your period data stays on your device, period.
Unlike other period apps that upload your most personal health data to remote servers, LunaLock was built from the ground up with one principle: your data never leaves your phone.
FREE FEATURES:
- Log period start and end dates with haptic feedback
- Smart cycle prediction with confidence ranges (not just averages)
- Track 6 common symptoms: cramps, bloating, headache, fatigue, acne, mood swings
- Log your daily mood with 6 mood options
- Record flow level from spotting to heavy
- Calendar view with period and prediction markers
- FaceID and PIN lock with emergency shake-to-lock
- Auto-lock timer for extra security
- Period reminders with customizable advance notice
- Onboarding privacy promise
- Delete all data anytime
- No ads, no accounts, no tracking

- Trend charts for cycle length, symptom frequency, and mood patterns
- Data export as PDF for doctor visits or JSON for other apps
- Home screen widget with countdown and cycle day
- 5 beautiful color themes (Luna, Rose, Ocean, Forest, Sunset)
- HealthKit write-only integration (optional)
- Monthly and annual cycle reports
- Emergency shake-to-lock

WHY LUNALOCK?
Other period apps like Flo and Clue require accounts, collect your data, and use subscriptions. LunaLock is different:
- $3.99 once, not $4.99/month forever
- Zero data collection - we literally cannot see your data
- FaceID lock means even someone borrowing your phone cannot see your period info
- Emergency shake-to-lock for when you need instant privacy
LunaLock. Your period. Your phone. Nobody else's.
