Private Cycles: Period and Ovulation Tracker Your Body. Your Data. Your Private Cycle. In an era where your most personal health information is often treated as a commodity, Private Cycles draws a line in the sand. We believe that your reproductive health data is yours alone. Designed with a privacy-first philosophy and a minimalist, premium aesthetic, Private Cycles provides a comprehensive tracking experience without the cloud, without the tracking, and without the compromise. THE PRIVACY-FIRST PROMISE Most health apps store your data on remote servers, making it vulnerable to data breaches, third-party sales, or legal requests. Private Cycles is different. Zero-Cloud Architecture: We never store your data on a server. On-Device Encryption: 100% of your logs stay encrypted on your physical device. Total Anonymity: No accounts to create, no email addresses to sync, and no profiles to build. You are a person, not a data point. COMPREHENSIVE TRACKING, REFINED Whether you are tracking a regular cycle, navigating irregular patterns, or planning a pregnancy, Private Cycles offers a professional-grade toolkit wrapped in a clean, distraction-free interface. Period and Ovulation: Effortlessly log flow intensity, symptoms, and moods. Our high-fidelity calendar provides at-a-glance clarity for your entire month. Fertility Insights: Identify your fertile window with precision using science-backed tracking methods. Pregnancy Mode: Transition seamlessly into pregnancy tracking with tailored insights and milestones as you progress toward your due date. Symptom Library: Log over 30 physical and emotional symptoms to identify recurring patterns in your health. MINIMALIST BY DESIGN Inspired by a minimalist aesthetic, Private Cycles strips away the clutter found in traditional period trackers. No pink-washed interfaces, no community forums full of noise, and no intrusive notifications. Just a sophisticated, dark-mode-optimized tool that respects your focus. KEY FEATURES AT A GLANCE: Chronological Feed: See your history exactly as it happened, with no algorithmic interference. Export Control: Generate a private, encrypted PDF or CSV report locally to share with your doctor. Smart Notifications: Discrete, customizable alerts for upcoming cycles or fertile windows. FaceID and Passcode Lock: An extra layer of biosecurity for the app itself. Join the movement of users reclaiming their digital autonomy. Experience the peace of mind that comes with knowing your health journey is for your eyes only. Terms of Use: https://privatecycles.com/terms Privacy Policy: https://privatecycles.com/privacy
