Mooneva Cycle
Mooneva Cycle: The Private Period Tracker That Never Sees Your Data
Your cycle data belongs to you — not to a company, not to their servers.
Mooneva is a private period tracker built from the ground up for offline-first, no-account menstrual health tracking. Every month, millions of women share intimate health data with apps that upload it to corporate servers — where it can be sold, breached, or subpoenaed. Mooneva works differently: all data stays on your device, always.
No accounts. No cloud sync. No data harvesting.
Unlike cloud-based period apps, this offline period tracker stores your cycle data exclusively on your phone. Nothing is transmitted. Nothing is shared. Privacy is not a premium feature — it is the foundation.
Why an Offline Period Tracker Is Safer
Data that never leaves your device cannot be exploited.
| Cloud-Based Apps | Mooneva Private Period Tracker |
|---|---|
| Data stored on company servers | Data stored only on your device |
| Vulnerable to data breaches | No server exists to breach |
| Requires account and personal information | No account. No registration. |
| Company can analyse your data | We cannot access your data — ever |
