Emberly is a period tracker with nothing to hide, because it holds nothing of yours. Your cycle lives on your iPhone: no account, no cloud, no ads, and nobody quietly sharing your health data with an analytics company. And you shouldn't need a subscription to track your own period. Emberly is free for your first full cycle, then a single $9.99 purchase makes it yours forever. WHAT IT DOES • Predicts your period and fertile window, and gets sharper with every cycle you log • Logs a day in seconds: flow, mood, energy, symptoms, sleep, notes • Shows your patterns: cycle length, regularity, and how each phase tends to feel • Reminds you before your period starts, with discreet wording so your lock screen keeps your business to itself • Locks behind Face ID or a PIN • Works completely offline, airplane mode included WHY IT'S DIFFERENT Most period apps run on servers, and health apps are not bound by HIPAA. Emberly can't share your data because it never has it: there are no servers, no analytics, no advertising SDKs, and no third-party trackers in the app. Everything is computed on your phone. Backups are files you create yourself and save wherever you choose, like your own iCloud Drive. Privacy here isn't a policy promise. It's the architecture. PRICING, PLAINLY Your first 30 days are free and include every feature, one full cycle's worth. Nothing to start and nothing to sign up for. When the free month ends, keeping access takes a one-time $9.99 purchase. No subscription, nothing renews, and there's nothing else to buy. If you decide not to purchase, your data stays yours: backing it up remains available either way. A NOTE ON HONESTY Emberly's predictions are estimates based on the dates you log. It is not a contraceptive, not a diagnostic tool, and not a substitute for a clinician. If something about your cycle concerns you, please talk to a doctor. Questions?
