At a glance

Everything stays on this phoneWhat you log is never uploaded, synced or shared. There is no account and no cloud. If you lose your phone or change to a new one, your history cannot be recovered.
Menna never uses the internetIt works exactly the same in airplane mode. You can check it yourself (see below).
Menna cannot see itNo ads, no analytics, no trackers and no server: the people who made Menna never receive your data. Anyone who can open your phone can open Menna, so use the Face ID lock to keep it to yourself.
You are in controlEdit any day, or delete everything from Settings whenever you want.
Estimates, not medical advicePredictions can be wrong and they are not birth control. Talk to your doctor before making health decisions.

Medical notice

Menna is a personal tracking tool. It is not a medical device and it does not give medical advice.
Period, fertile window and ovulation predictions are estimates calculated from what you log. They can be wrong, and every body is different. How it works (in the menu) explains exactly how they are calculated.
The fertile window is only an estimate. Days outside it are not “safe days”: you can get pregnant on other days of your cycle, especially if your cycles vary.
Do not use Menna by itself to prevent or plan a pregnancy, to diagnose a condition, or to decide on treatment, medication or birth control.
Averages, regularity and the visit report are references to talk about with your doctor, not a diagnosis.
The dates for changing or checking your birth control are cautious estimates, because each brand lasts a different time. Use the date your doctor or your method's card gives you; you can change it in Birth control & visits.
Reminders can fail to arrive, for example if notifications are turned off, a Focus or Low Power Mode is on, or the phone is off. Do not rely on Menna alone to take your pill or change your birth control on time. If you miss a pill, follow its leaflet or ask your doctor.
Talk to your doctor or gynecologist before making health decisions, and follow their instructions over anything Menna shows.
A late or missed period can have many causes, including pregnancy. If you might be pregnant, take a pregnancy test and follow your doctor's guidance. Menna does not follow a pregnancy.
Contact your doctor right away for very heavy bleeding, severe pain, or anything that worries you. In an emergency, call your local emergency number.

Privacy policy

Last updated October 21, 2026

What Menna stores

Only what you enter yourself. Each day: period, flow, discharge, mood, symptoms, sexual activity (with or without protection) and whether you took your pill.
Profile: your name, your birthday, and the period and fertile window reminders.
Birth control and visits: your method, the date it was placed and its next change or check-up, your daily pill reminder time, and your gynecologist visit with any notes you write for it.
Settings: the language, the appearance (light or dark), the Face ID lock and when to ask for it again, discreet notifications, and which tutorials you have already seen. The visit report is built on screen from this same data and is not saved separately.

What Menna never does

It never connects to the internet: no servers, no sync, nothing comes in or goes out with your data.
It never shows ads, and it has no analytics, tracking or advertising services from other companies.
It never sells, shares or uses your data for marketing, profiling or research.
It does not use artificial intelligence, and your data is never used to train anything.
It does not read Apple Health or any other app, and it does not use your location, contacts, camera, microphone or photos.

Where it is kept

In Menna's private storage on this phone. Other apps cannot read it.
It is kept out of iCloud and computer backups on purpose, so it never leaves the phone. The other side of that: deleting Menna or changing phones erases your history, and there is no way to recover it.
Your phone's own protections (passcode and encryption) apply to it.

Face ID and screen privacy

The optional Face ID lock (in Settings) hides Menna's screens unless someone unlocks it with your face or your phone's passcode. It does not add extra encryption. If your iPhone has no passcode or Face ID set up, the lock cannot check anything and Menna opens normally.
Face ID is handled entirely by iOS. Menna only learns whether it worked, and it never receives your face data.
When you leave Menna, its screen is covered, so the iOS app switcher never shows what you logged.

Notifications

Menna only sends the reminders you turn on: your daily pill, your period and your fertile window (1, 3 or 5 days before), and the change or check-up of your birth control and your gynecologist visit (these two, a week before and on the day).
They are scheduled on your phone itself. Menna does not use push notifications or any server to send them.
The daily pill reminder has a button to mark the pill as taken without opening Menna. iOS asks you to unlock your phone first, and the mark is saved only on this phone. If Menna was fully closed, iOS may not deliver the tap, so check the day in the app if in doubt.
A reminder can appear on your lock screen. With Discreet notifications (in Settings) it only says “Reminder”. They are on when you first install Menna.

Permissions

Menna asks for only two permissions: Face ID and notifications. Both are optional. You can change either one at any time in the iOS Settings app, and Menna keeps working without them.

Check it yourself

Turn on airplane mode: Menna works exactly the same, because it never needed the internet.
On your iPhone, open Settings › Privacy & Security › App Privacy Report and turn it on. After using Menna, it should show no network activity for it.
Menna's App Store page shows Apple's privacy label “Data Not Collected”.

Your rights over your data

See it: everything Menna stores is shown in the app itself.
Correct it: edit or clear any day, your profile, and your birth control and visits at any time.
Delete it: use “Delete all data” in Settings, or delete Menna. Deleted data cannot be recovered.
Because nobody else has a copy, there is nothing to request from us and nothing we could recover for you. Menna does not have an export option yet.

Crash reports from Apple

If you have chosen in iOS Settings to share analytics with app developers, Apple may send the developer crash reports. They are meant to describe the technical error, not what you log in Menna. You can turn this off in Settings › Privacy & Security › Analytics & Improvements.

This web page

The website mennacycle.app is separate from the app, so the promises above about the app do not cover it. The website is hosted and delivered by Cloudflare, as any website is: Cloudflare processes the technical data needed to serve the pages, such as your IP address and your browser. The site also uses Cloudflare Web Analytics, which counts visits in aggregate: how many there are, which pages they open, and from which country and browser. The site does not show ads. For how Cloudflare handles this data, read Cloudflare's privacy policy.

Children

Menna is not designed for children under 13.

Changes to this policy

If this policy changes, the new version will appear in the app and in Menna's App Store listing, with a new date. A change will never start collecting your data without asking you first.

Terms of use

Menna is a paid app with a one-time price, sold through the App Store: Apple handles the payment, taxes and refunds. It has no subscriptions, in-app purchases or ads.
Menna is provided as it is, without any guarantee that it will be accurate, available or free of errors, to the extent the law allows.
You decide how to use what Menna shows you. It is a tracking tool and does not replace your doctor, a pregnancy test or your birth control's instructions.
To the extent the law allows, the developer is not responsible for decisions made based on Menna's estimates or reminders, or for data lost when Menna is deleted or a phone is lost, broken or replaced.
Nothing here limits the rights that consumer law gives you and that cannot be waived.
These terms add to Apple's standard license agreement for apps, which also applies.
Menna is meant for people 13 and older.
