Absolutely. On mobile, you can stay fully anonymous — all data stays on your device using encrypted storage (iOS Secure Enclave / Android AES-256-GCM) with no account needed. If you connect an account, you choose what to sync with 3 granular toggles. On web, you sign in with Apple or Google and your data is securely stored in Firebase with encryption in transit and at rest. We never sell, rent, or trade your health data. Ever.
Yes. Naya reads 15+ data types from Apple Health including menstrual flow, weight, steps, sleep, heart rate, and basal body temperature. On Android, it integrates with Google Health Connect for the same data. It also writes back flow and water data. Health data is never sent to our servers.
The AI Health Assistant is a cycle-aware chatbot available with Naya Plus. It knows your current cycle day, phase, today's symptoms and mood, and gives personalized, evidence-based wellness advice. It supports 25+ languages. Your conversations stay on your device — never stored on servers.
Naya calculates your average cycle length from completed cycles and predicts your next period, ovulation day, and fertile window. As you log more cycles, predictions become more accurate. The algorithm identifies your current phase (Period, Follicular, Ovulation, Luteal) automatically.
On mobile, yes! Naya works fully anonymously — no email, no sign-up, 100% private. Everything stays on your device. If you want to sync across devices or use the web app, sign in with Apple or Google at any time. The web app requires an account (Apple or Google Sign-In) to use.
Yes. You can delete your account and all associated data from the Profile screen. This permanently removes all cloud data (Firestore), your Firebase account, and local app data. This is GDPR-compliant and irreversible. Apple Health / Health Connect data is managed separately through those apps.
Naya is available on iOS (iPhone, requires iOS 18.0+), Android (requires Android 9.0+), and the Web at app.naya.plus. All three platforms share the same core features and your data syncs seamlessly between them. Sign in with the same account on any platform to access your cycles, logs, and subscription everywhere.
