## Description
🌙 CrescentCycle — Private Cycle Tracking for Two
Most cycle tracking apps are built for one person. CrescentCycle is built for two — you and the partner who wants to understand, support, and show up for you. Track your cycle with strong encryption on your device and on our servers, and optionally share what you want, with who you want, at the permission level you choose.
━━━━━━━━━━━━━━━━━━━━
BUILT FOR COUPLES
━━━━━━━━━━━━━━━━━━━━
- Link with your partner using a private 6-character couple code
- You control what they see — View Only, Can Add, or Full Access
- Partners get a real-time dashboard: cycle day, mood, energy, symptoms, and thoughtful support suggestions
- Send shared notes back and forth in a private chat
- Supporting partners can log their own support actions and see the full cycle history
- Unlink anytime, instantly
━━━━━━━━━━━━━━━━━━━━
COMPLETE CYCLE TRACKING
━━━━━━━━━━━━━━━━━━━━
- Daily logging for flow, mood, energy, symptoms, and free-text notes
- Accurate period and fertile window predictions based on your actual history
- Color-coded monthly calendar with phase overlays
- Every entry tagged with the current moon phase 🌙
- Fix a wrong cycle start date without losing your history
- Streak tracking to keep you consistent
- Insights dashboard: average cycle length, mood trends, symptom patterns
- Export your full data to CSV anytime — your data belongs to you
━━━━━━━━━━━━━━━━━━━━
PRIVACY-FIRST, ENCRYPTED THROUGHOUT
━━━━━━━━━━━━━━━━━━━━
Your health data deserves real protection — not just a promise.
- AES-256 encryption on every piece of data stored on your device
- 256-bit cryptographically random encryption key, stored in the Android Keystore
- HTTPS-only network communication — cleartext blocked, user-installed proxy certificates rejected
- Screenshot and Recent Apps preview protection on every screen
- Cloud backup disabled — your health data never leaves your control
- Notifications contain zero health info — nothing shows on your lock screen
- Encrypted AWS backend — data encrypted at rest and in transit
━━━━━━━━━━━━━━━━━━━━
MEDICATIONS TRACKER
━━━━━━━━━━━━━━━━━━━━
- Add medications with dosage and daily reminder times
- Mark as taken or skipped each day
- Per-medication notifications that survive device reboots
━━━━━━━━━━━━━━━━━━━━
MAKE IT YOURS
━━━━━━━━━━━━━━━━━━━━
- 6 hand-crafted color themes: Luna, Rose, Ocean, Forest, Sunset, Midnight
- Dark mode with optional auto-sunset scheduling
- Personalize with cycle nickname and emoji
- Font size, date format, and first day of week all configurable
- Haptic feedback with 5 distinct patterns — or turn it off entirely
━━━━━━━━━━━━━━━━━━━━
ACHIEVEMENTS & PROGRESS
━━━━━━━━━━━━━━━━━━━━
- Earn achievements for consistency and milestones
- Build a badge collection across Common, Rare, Epic, and Legendary tiers
- Level up with XP as you track
- Celebrate streaks with haptic feedback
━━━━━━━━━━━━━━━━━━━━
SMART NOTIFICATIONS
━━━━━━━━━━━━━━━━━━━━
- Heads-up 2 days before your predicted period
- Gentle check-in if your period is running late
- Daily logging reminder at your chosen time
- All alerts restore automatically after a reboot
━━━━━━━━━━━━━━━━━━━━
WHY CRESCENTCYCLE?
━━━━━━━━━━━━━━━━━━━━
Because cycle tracking shouldn't be a black box — and it shouldn't cost you your privacy. CrescentCycle keeps your data encrypted on your device, syncs securely to an encrypted backend, and gives you the option to share only what you choose with only who you choose.
No ads. No selling your data. No dark patterns. Just a cycle tracker built the way it should be.
Download CrescentCycle and start tracking — together, or on your own.
