Sync vs Cara

Sync Period tracks cycles locally and supports private sharing with a partner or friend. Log periods, symptoms, moods, and notes; view your calendar and pattern summaries; set optional reminders; and import supported Flo, Clue, Drip, or generic CSV data after reviewing what Sync can recognize. Your cycle history is encrypted on your device. Private predictions adapt to your recent cycle history and confirmed corrections entirely on your device. Sync shows a likely-start window and confidence level, learns recurring pre-period patterns, and can use an enabled BBT signal or positive ovulation test without uploading those health details. Predictions become more cautious when history is sparse or variable. Partner sharing is optional and off by default. You choose which supported cycle details to share. Updates are end-to-end encrypted and require the complete private invite to open. Each encrypted relay update expires after no more than 30 days; active sharing renews that rolling expiration when a new update is published. Recent physical symptoms and flow, sex-drive and intimacy check-ins, and moods are three separate opt-ins that can each be turned off again. Intimate sharing is off by default and never indicates consent. Discharge, medications, written notes, and other sexual details remain private. Sync Period has no ads, no behavioral analytics SDKs, and no required account. You can export a private backup or permanently delete local app data at any time. Cycle predictions and pattern summaries are estimates. Sync Period does not provide diagnosis, contraception, or medical advice.

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.
