Period & pregnancy tracker
Your cycle, your phone, your business.
Everything you track in Mahina stays on your phone, encrypted — your dates, your symptoms, how you're actually feeling, the notes meant only for you. No account to set up. No cloud quietly syncing in the background. Right now the app doesn't even go online, so there's simply nothing to leak.
Your cycles move around a bit, so we show a window instead of one date we'd only have to walk back. Log a few more and it tightens up.
On your device, encrypted
What you log lives in an encrypted database on your phone, and it stays there. Nothing gets uploaded behind your back.
No account, ever
No sign-up, no phone number, no email. There's nothing tying what you track to who you are.
Honest predictions
When your cycles are all over the place, we show a range and how sure we are, instead of pretending we know the exact day.
Delete means delete
Tap once and it's gone from your phone for good. There's no copy sitting on a server for us to quietly keep.
Reminders stay discreet
Notifications keep it vague on your lock screen — no cycle or pregnancy details for anyone glancing over your shoulder, unless you turn that on.
Free, no ads
All of it's free, nothing's locked behind a paywall, and there are no ads. What's free today stays free.
What Mahina does
A calm companion for your cycle, and your pregnancy
Log your period and symptoms, follow a pregnancy week by week, and get plain-language nudges about what's normal. It all works with your phone in airplane mode.
Track your period
Tap out a period or a symptom in a couple of seconds, from the calendar, a home-screen widget, or straight from a notification. Your history and stats build up quietly in the background.
Pregnancy mode
Expecting? Switch modes and follow your week, with a gentle way out if things change. Your cycle history stays put through the switch.
Insights, on device
The "Today" card tells you where you are in your cycle and what tends to happen around now. It's all worked out on your phone, no algorithm phoning home.
A PDF for your doctor
Heading to an appointment? Export a tidy summary of your recent cycles or your pregnancy and share it however you like. Only when you decide to.
Lock it, back it up
Put a PIN or your fingerprint in front of the app, and keep an encrypted backup that only your passphrase can open.
Yours to share, or not
Made a card for your partner, a parent, or your doctor? You see exactly what's on it before it goes anywhere. Nothing leaves without you.
Privacy you can check
