About this app

Polycycle – Safe. Private. Local.
Take full control of your most intimate data.
Most period tracking apps make money by selling your data. Polycycle is different. We believe that your health data belongs to you and no one else. That’s why we built an app centered around radical privacy and state-of-the-art security.
Why Polycycle?

100% Local Storage: Your data never leaves your smartphone. There is no cloud synchronization and no external servers. Everything you enter stays in your possession.

No Data Collection: We don’t track you. We don’t analyze your behavior. We never sell your information to advertising networks or third parties.

No Account Required: No registration, no email address, no passwords, and no "Login with Facebook." Download the app and start immediately—completely anonymous.

Total Transparency: You have full control over your backups. Create manual backups and decide for yourself where to store them safely.
Key Features:

Cycle & Period Tracking: Log your period, pain levels, flow intensity, and personal notes with just a few taps.

Precise Predictions: Receive calculations for your next period and your fertile window (ovulation) based on your individual data.

Detailed Analytics: Identify patterns in your cycle. Track pain intensity over time to better understand your health.

Custom Reminders: Get discreet notifications for your next period or to remind you to take your pill.

Multilingual: Available in English and German.
Security isn’t a feature—it’s a promise.
In an era where digital privacy is becoming increasingly rare, Polycycle provides you with a protected space. Your cycle data is sensitive—we treat it that way.
Download Polycycle today and experience cycle tracking without compromising your security.
