Log your period in seconds, see when your next one is likely, and keep a gentle diary of how you feel — all with your data kept on your own device.

PREDICT YOUR CYCLE
• See your predicted next period and current cycle day at a glance.
• A clear calendar shows your logged days, predicted period, and an estimated fertile window.
• Predictions work from day one using the cycle length you set, then sharpen automatically as you log more cycles.

A GENTLE MOOD DIARY
• Note how each day felt with a simple mood and a private journal entry.
• Look back over time and notice your own patterns.

SEE YOUR PATTERNS
• Trends show your cycle length over time, how long your periods last, and how your mood moves through the month.

CALM, PRACTICAL READS
• A small library of clear, supportive articles — easing cramps, understanding your cycle phases, riding out PMS, and knowing when something is worth raising with a doctor.

PRIVATE BY DESIGN
• Your cycle and diary data stay on your device. We never upload it.
• Optional app lock with your fingerprint or device passcode.
• Export a backup any time so a new phone doesn't mean starting over.

GENTLE REMINDERS
• Optional nudges before your period is due, when your fertile window is estimated to begin, if your period runs late, and a daily prompt for your diary.

MADE TO FIT YOUR DAY
• A home screen widget shows your cycle day at a glance.
• Light and dark themes.
• Available in English, Lithuanian, Russian, Polish, Spanish, French, German, Portuguese and Turkish.

Please note: Senuna Cycle is for tracking and awareness only. The fertile window is an estimate — it is not a method of contraception, and the app does not diagnose or treat any medical condition. If anything about your cycle worries you, please speak to a healthcare professional. ## Rankings - #3,016,663 — Overall ## Permissions and access ### Permissions - `android.permission.ACCESS_ADSERVICES_AD_ID` - `android.permission.ACCESS_ADSERVICES_ATTRIBUTION` - `android.permission.ACCESS_ADSERVICES_TOPICS` - `android.permission.ACCESS_NETWORK_STATE` - `android.permission.FOREGROUND_SERVICE` - `android.permission.INTERNET` - `android.permission.POST_NOTIFICATIONS` - `android.permission.RECEIVE_BOOT_COMPLETED` - `android.permission.USE_BIOMETRIC` - `android.permission.USE_FINGERPRINT` - `android.permission.VIBRATE` - `android.permission.WAKE_LOCK` - `com.android.vending.CHECK_LICENSE` - `com.google.android.gms.permission.AD_ID` - `com.senuna.cycle.DYNAMIC_RECEIVER_NOT_EXPORTED_PERMISSION` ## Similar extensions and apps - [MyCycle Period Tracker](https://chrome-stats.com/d/com.tntech.mycycle) — 71 users - [Know Your Cycle Period Tracker](https://chrome-stats.com/d/in.launchgrid.periods) — 26 users - [Period Tracker: Cycle Calendar](https://chrome-stats.com/d/com.womenhealth.periodtracker.pregnancytracker) — 604 users - [Period Tracker & Cycle Diary](https://chrome-stats.com/d/com.appinitdev.birth.free) — 2,182 users - [Private Period & Cycle Tracker](https://chrome-stats.com/d/com.zeppelinapps.privateperiodcycletracker) — 2 users - [Cycluna](https://chrome-stats.com/d/net.quietflare.cycluna) — 44 users - [Seluna: Period tracker](https://chrome-stats.com/d/com.cvragam.seluna) — 68 users - [Periodia: Period Tracker](https://chrome-stats.com/d/com.bergyx.periodia) — 13 users - [Private Period Tracker & Cycle](https://chrome-stats.com/d/com.tidelle.app) — 140 users - [Period Tracker: Cycle Calendar](https://chrome-stats.com/d/com.capstone.periodtracker.womancalendar) — 4,896 users - [Period Tracker: Cycle Calendar](https://chrome-stats.com/d/com.software41.myperiod) — 87 users - [My Period Calendar](https://chrome-stats.com/d/com.bymirza.periodcalendar) — 301 users --- Source: [Chrome-Stats](https://chrome-stats.com/d/com.senuna.cycle)
