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.

CARA: YOUR CYCLE, YOUR PHONE, YOUR CONTROL Track your period and cycle with absolute privacy. Cara is a period and menstrual cycle tracker that stores every piece of your data locally on your iPhone—never on servers, never in the cloud, never sent anywhere. WHY CARA Most period tracking apps harvest your data. They sell anonymized insights to pharmaceutical companies. They track your moods, your health patterns, your fertility window. They show you ads. Cara is different: it's an appliance, not a platform. Your cycle data belongs to you. PRIVACY FIRST • Zero cloud storage. All data stays on your device. • Encrypted at rest. AES-256 encryption via SQLCipher. • No servers. No accounts. No sign-up. • No analytics. No tracking. No ads. • Optional biometric lock. Face ID or Touch ID protects your entries. • Delete instantly. Uninstall = full data deletion. No recovery, no backup—your choice. TRACK WHAT MATTERS • Menstrual flow and symptoms (cramping, mood, energy, headaches, spotting, etc.) • Ovulation and fertile window predictions (calendar-based; not medical advice) • Cycle length and pattern tracking over months • Custom tags for your health patterns • Simple, glanceable calendar view • Day-by-day insights without judgment BEAUTIFUL DESIGN Cara's interface is calm and focused. An animated ocean-wave background shifts through six daily phases—night, dawn, morning, midday, sunset, dusk—creating an ambient, breathing experience. Your cycle data uses a soft color language: coral for menstrual, teal for follicular, lavender for luteal. No gamification. No artificial streaks or badges. Just your data, clearly presented. WHAT'S NOT IN CARA • No account creation • No cloud sync • No ads or sponsored content • No AI summaries shipped to servers • No premium tier or paywall • No third-party data sharing • No health claims or medical advice PERMISSIONS & YOUR DATA Cara requests biometric permission only if you enable Face ID or Touch ID. No location access. No microphone. No camera. No contacts. No calendar integration (your cycle lives only in Cara). EXPORT & BACKUP Your data is yours. Export your full cycle history as CSV anytime. No vendor lock-in. FREE. FOREVER. Cara is free, with no in-app purchases and no premium features. Your privacy isn't a tier—it's the entire product. Built for people who want to track their cycle without being tracked. Cara is health tracking for humans who believe data privacy is not negotiable. Need help?
