About this app

Ritulaya is a privacy-first period tracker that keeps your data on your device and helps you understand your cycle with predictions computed entirely on your phone. No account, no cloud, no analytics.

Track your period and log how you feel each day. Ritulaya predicts your next period, fertile window, and ovulation day on-device, so your most sensitive data never leaves your phone. Your data is encrypted at rest and stays private unless you choose to sync it.
