The Swiss cycle app that knows nothing about you.

Track your period, log symptoms, see predictions, in ten seconds a day. Everything stays on your device. No account, no cloud, no advertising.

What a cycle with Malve feels like.

Not a feature list, just one month the way it actually goes.

Day1

Your period starts. Two taps, done.

Tap the flow level, save. Under ten seconds, no keyboard at all. Symptoms and mood only if you feel like it.

Day12

One glance in the morning is enough.

The ring shows where you are: cycle day, phase, next period. One number instead of ten widgets. An ordinary day needs no more than that.

Day26

One reminder. Your only one.

Two days ahead, Malve speaks up exactly once. When, and whether at all, is up to you. It is the only message this app ever sends on its own.

Show them what helps you right now.

A walk, something sweet, or simply some quiet. In two taps, send the people close to you a card so they know how to be there for you. No symptoms, no data, just what matters.

Care, not surveillance. You only share what you send yourself.

Your data has a short way to go.

At Malve, privacy is not a setting you have to go looking for somewhere. It is how the app is built. This is how far your data travels, and not one step further:

You log it

Period, symptoms, mood, captured in a few taps. No keyboard, in under ten seconds.

No account, no email, no sign-up

Your iPhone does the work

Entries, predictions and insights are created in a database on your device. None of it leaves the phone.

Backup: an encrypted file in your hands

Nothing.

No server, no cloud, no recipient. There is simply no place your data could arrive at.

And therefore no data breach either

Malve arrives in autumn 2026. Until then none of this can be verified, and we are not pretending otherwise. What is written here is the architecture we are committing to now, so that you can hold us to it at launch.

How the trial works
Day 1

Install it and start. Everything open, no account, no payment details.

Day 14

If you like Malve, you unlock it: one-off or yearly. If you would rather not, we do not ask a second time.

After that

Even without unlocking, your entries stay readable and exportable. Only predictions and insights pause.

contact@malve.app
Can I use Malve for contraception?

No. Malve is a diary and observation tool, not a contraceptive and not a medical device. The predictions are estimates based on your previous cycles. For contraception, please talk to your gynaecologist about certified methods.

Can I share my cycle with my partner?

Yes, but differently from other apps: you actively send individual cards or reports through your own apps, for example a forecast card by message. Permanent live access to your data deliberately does not exist. Only what you send yourself, case by case and by tapping, gets shared.

What happens when I change phones?

In Malve you create an encrypted backup as a file and store it wherever you like: your own iCloud, Drive or AirDrop. On the new device: open the file, enter the passphrase, done. On top of that, your data is part of your normal device backup in your own account.

Is there a version of Malve for Android?

Malve starts on iPhone. An Android version is planned as soon as the iOS app runs smoothly. Join the waiting list and tell us you use Android, that helps us set priorities.

Why isn't Malve free?

Because somebody always pays. With “free” cycle apps you pay with your data, or you get pushed into a subscription. Malve turns that around: you pay a fair price, yearly or once, and in return the app stays free of advertising, free of tracking and entirely yours. The price stays as it is. No discount campaigns, no pressure.

What happens if I cancel the yearly plan?

Nothing that annoys you. Your entries stay readable, the calendar keeps working, and you can export everything at any time. Only predictions, insights and the cycle report pause until you unlock again. Your data is your data, even when you stop paying.

Who is behind Malve?

Malve is developed independently in Switzerland: without investors demanding growth at any cost, and without an ad network in the background. The app is named after the medicinal plant that gave the colour mauve its name.

Our partners.

We have none yet, and we would rather write that down than show a row of borrowed logos. If you run a practice, teach classes or keep a shop and would like to recommend Malve, get in touch.
