Mooneva Cycle – Period Tracker

Mooneva Cycle is a private, fully offline period tracker and menstrual cycle calendar. Track your period, predict your next cycle, follow your fertile window and ovulation, and log daily symptoms and mood — all without an account, and without a single byte leaving your phone.

Why offline matters

Most period tracking apps upload your cycle data to company servers, where it can be sold to advertisers, exposed in a breach, or demanded by law enforcement. Mooneva has no servers at all. Your data is encrypted on your device using PBKDF2 and AES-GCM, and the app does not even request the internet permission — there is nothing to transmit, and nothing to hand over.
