Feve: Ovulation Tracker & Diet

Welcome to Feve—your private cycle companion, smart ovulation tracking calendar, and period-synced recipe log built for your unique TTC path. Most tracker apps upload intimate data to cloud networks. Feve is entirely different. Built on a serverless, zero-knowledge architecture, Feve stores and encrypts 100% of your tracking data directly on your own device hardware. Guarded by a private PIN, your history remains secure. Because we do not hold a master key on an external server, it is mathematically impossible for anyone—including the developer—to view or leak your metrics. WHY CHOOSE FEVE FOR YOUR TTC & OVULATION TRACKING JOURNEY? • ON-DEVICE ONLY PRIVACY: No accounts, no profiles, and zero cloud data storage. Feve secures your cycle history using a private PIN that acts as your local encryption key. For effortless access, seamlessly enable secure fingerprint biometric login during setup or anytime later. • SMART OVULATION WINDOW CALENDAR: Feve utilizes a smart localized tracking algorithm to analyze your unique history. This mathematical model dynamically calculates cycle variance to map out your predicted ovulation day and identify your estimated peak fertility windows. • TRACKING NATURAL FERTILE SIGNS: Effortlessly monitor your body's natural signs throughout your cycle. Record daily mood, energy, sleep, waking temperature (BBT) trends, weight, and fluid observations to understand your unique biological patterns and track natural fertile signs with precision. • TARGETED NUTRITION FOR YOUR FERTILE DAYS: Discover premium culinary options tailored for your specific cycle windows.
