Store description excerpt
Phasura is a period tracker that keeps everything on your phone. There is no account to create and no server to sign in to. The app makes no network requests of its own, so nothing you log is sent anywhere. Everything is encrypted with AES-256-GCM before it is written to storage, and the key never leaves your device. WHAT YOU CAN TRACK Period days and flow. Symptoms including cramps, headaches, bloating, fatigue and backache. Mood. Free-text notes for anything else worth remembering. PREDICTIONS, HONESTLY LABELLED Phasura estimates your next period from the dates you have logged, and shows a likely range rather than pretending to know the exact day. It marks an estimated fertile window and tells you where that estimate comes from. The app is equally clear about what it cannot do. Calendar-based predictions are not a method of contraception. The patterns Phasura flags are prompts to talk to a clinician, not a diagnosis. There is a plain-English screen inside the app explaining how every number is worked out, and where that method breaks down. PATTERNS OVER TIME Once you have logged a few cycles, Phasura shows when your symptoms tend to appear. If your headaches cluster in the days before your period, you will see it. It waits until there is enough history to say something meaningful, and tells you how much more it needs rather than guessing early. LOCKING Set a PIN, add fingerprint or face unlock, or use no lock at all. Your PIN is never stored anywhere. It is turned into an encryption key each time you enter it. YOUR DATA, YOURS TO MOVE Create an encrypted backup protected by a passphrase you choose, so your history can move to a new phone. Export a readable file if you want your own copy or something to show a clinician. Delete everything from inside the app whenever you like, permanently and without asking anyone. QUIET BY DESIGN Phasura is built to be unremarkable. Neutral colours, no loud branding, and nothing on screen that announces what the app is to someone glancing over your shoulder.
