A private period tracker app for India

Cycella is free on Google Play for Android. The iPhone version is coming soon.

Cycella is a free period tracker, period calendar and ovulation calculator made first for women in Nepal and available in India too. It works in English or Hindi, keeps your cycle on your own phone, and works without internet. No account, no phone number, no ads.

Why privacy matters for period apps in India

A period app knows when you bleed, your symptoms, your mood and whether you are trying to get pregnant. In 2019, Privacy International found that several popular period apps, including ones widely used in India, were sending this kind of intimate data to Facebook. Many phones in India are also shared with family. Cycella is built so there is as little data as possible to leak: no account, logs stored encrypted on the phone, and nothing sold. Read what to check before trusting any period app.

What Cycella does

• Predicts your next period from your own logged cycles, not a fixed 28-day guess.
• Estimates ovulation and your fertile window as awareness only. It is not a method of contraception.
• Period calendar with logged and predicted days in one view.
• Log flow, mood, symptoms and pad changes in a few taps.
• Doctor report: a one-page summary of your cycles to show a gynaecologist or doctor.
• Optional partner sharing: you choose what a partner sees, and it is end-to-end encrypted.

In Hindi or English

You can use the whole app in Hindi or English, and switch any time from the Me tab. The doctor report is available in Hindi too, so you can hand it to a doctor in whichever language suits you both.

Works offline, private on a shared phone

Logging and predictions happen on your phone, so Cycella works without internet or mobile data. You can lock the app with a PIN. Internet is only used if you choose to turn on encrypted backup or partner sharing. See our Privacy Policy.

Irregular periods, PCOD and PCOS

Irregular periods are a common worry, and PCOD or PCOS is one of the conditions doctors check for. In 2026, PCOS was renamed PMOS. Cycella can't diagnose it, but a record of real cycle dates makes that appointment much more useful. Read PCOS, PCOD and PMOS: what's the difference? and why is my period late?

When can I download Cycella in India?
