Luna vs Haven

Luna is the period and fertility tracker that keeps your most personal health data exactly where it belongs — on your device. No accounts. No cloud sync. No data sharing. Just intelligent, private cycle tracking powered entirely by on-device machine learning. YOUR DATA NEVER LEAVES YOUR PHONE Luna was built from the ground up with privacy as the foundation. Every prediction, every insight, every log entry is processed and stored locally. We can't see your data because it never reaches us — not even anonymized. SMART PREDICTIONS, PRIVATELY POWERED Luna's on-device ML model learns your unique cycle patterns over time, delivering increasingly accurate predictions for: Period start and end dates Fertile windows and ovulation estimates PMS and symptom pattern recognition Cycle length trends and irregularities TRACK WHAT MATTERS TO YOU Daily symptom and mood logging Flow intensity and duration Basal body temperature (BBT) Cervical mucus and ovulation signs Intimacy and contraception notes DESIGNED FOR EVERY BODY Luna adapts to irregular cycles, post-hormonal transitions, perimenopause, and more. There's no "normal" cycle — Luna learns yours. BUILT FOR TRUST At a time when reproductive health data has never been more sensitive, Luna takes a firm stance: what happens on your phone stays on your phone. No account required to get started. No subscription needed to unlock your own data. https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Most period trackers make money from your data, or store it on servers that can be breached, sold, or subpoenaed. Haven is built the opposite way: your information stays on your phone. PRIVACY THAT'S A FACT, NOT A PROMISE No account. There's nothing to sign up for, and nothing for us to hold. No network. Haven makes no internet requests — your logs have nowhere to go. No trackers. No analytics, no advertising SDKs, no third parties. On-device intelligence. Reflections are generated by Apple's on-device AI. Your entries are never uploaded. EVERYTHING YOU NEED TO TRACK Log flow, symptoms, mood, and private notes in seconds. See your current cycle day and a clear prediction for your next period. View a fertile-window estimate for awareness. Browse your history on a calendar that reveals your patterns at a glance. Lock everything behind Face ID, and back up to a passphrase-encrypted file only you can open. REFLECTIONS THAT STAY PRIVATE Haven Premium unlocks gentle, on-device reflections drawn only from your own history — patterns surfaced quietly, without a server ever seeing your data. Tracking itself is free, forever. Haven is a tracking and awareness tool. It does not provide medical advice and is not a form of contraception. — Haven Premium is an auto-renewable subscription.
