Store listing
By Sasa Kolda, from the App StoreDescription by Sasa Kolda Written by the developer, not by AppBrain. Click to read.
Most cycle trackers profit from your most intimate health information. We built an app that does the exact opposite: complete, accurate cycle insights with zero compromises on your privacy.
Your reproductive health data is among the most sensitive information you possess. Most cycle tracking apps store your logs on cloud servers, sell data to third-party brokers, or use it for targeted advertising.
We built this app on a simple premise: Your Body. Your Data. Period.
Why Choose Complete Privacy?
100% On-Device Storage: Everything you log is saved locally on your iPhone. We do not host cloud servers, hold decryption keys, or have access to your health history.
No Account Required: Download and start logging immediately. No email registration, phone numbers, or social logins necessary.
Intelligent & Simple Cycle Tracking
Accurate Predictions: Get reliable forecasts for upcoming periods, fertile windows, and ovulation days.
Comprehensive Symptom Logging: Track cramps, mood swings, energy levels, skin changes, flow intensity, and custom notes.
Take complete control of your cycle health with 100% privacy and peace of mind.
