About this app

A private period tracker with no accounts or cloud sync.
Build a streak with quick daily logs and discover your unique cycle patterns.
All data stays securely on your device.

Cycle Streak is a private period tracker that lives entirely on your device, no accounts or cloud sync needed. With simple daily logging, you can quietly and accurately understand your body's unique patterns without complex setups.

Why Cycle Streak?

Quick Daily Logging
Easily record your period, mood, symptoms, and a short memo all on one screen. No complicated questionnaires or lengthy surveys – just the essential information you need.

Build a Habit with Streaks
As you log daily, your progress is shown as a streak. See your current streak and whether you've logged today right on the home screen, helping you build a consistent tracking habit naturally.

Calendar & Predictions at a Glance
Quickly view past period dates on the calendar and see predicted start dates based on your entries. Please note that predictions are for reference only and should not be used for contraception or medical decisions.

Earn Badges as You Track
Unlock badges for milestones like your first log, 7-day streak, 30-day streak, completing your first cycle, and more. Small achievements motivate consistent tracking.

Your Data Stays on Your Device
Cycle Streak requires no sign-ups, logins, or cloud synchronization. All your period data is stored exclusively on your device and is never sent to external servers or shared. The app is offered for free with banner, interstitial, and rewarded ads from Google AdMob; the ad network does not access your period records.
