01 Record what happens.
02 See the bigger picture.
03 Stay in control.
LESS SEARCHING. MORE CLARITY.
What matters today.
And how you feel.
A quick entry for today. A clear record to look back on. ZyklusKlar brings both together.
The screenshots show the German app. An English-language app version is planned.
Estimates are for orientation only. They do not confirm fertile or infertile days and must not be used for contraception.
A RECORD THAT REFLECTS YOUR REALITY.
A day without bleeding.
A pause.
A day without bleeding does not have to mean your period has ended. In ZyklusKlar, you can record it as a pause and keep the same period open.
You decide when to mark the start, a pause or the end. If you remember something later, you can correct your entry.
FITS INTO YOUR DAY
Make a quick entry.
Get on with your day.
At home, after a workout or during a short break at work: record what matters today. There is no need to plan your day around the app.

PRIVACY AT THE CORE
Your most personal diary.
Stays with you.
Health data is personal. ZyklusKlar stores your entries locally on your device. No account is required, there are no ads, and there is no server collecting your health records.
Under your control
An optional PIN lock and encrypted backups help you protect your records.
Discreet by design
On-device reminders use neutral wording. A daily check-in is optional.
READY FOR YOUR NEXT APPOINTMENT
Less “sometime last month”.
More “here’s my record”.
When did the bleeding happen? What symptoms came with it? Your PDF report brings your recorded entries together in a clear overview. Read it, print it and take it with you.
ZyklusKlar helps you keep records. It does not diagnose conditions or replace medical advice.

GOOD TO KNOW
Clear questions.
Clear answers.
Does ZyklusKlar require a subscription?
No. ZyklusKlar costs €14.99 as a one-time purchase. This includes all features available at the time of purchase. There are no monthly fees and no ads.
Where is my health data stored?
Your entries are processed and stored locally on your device. ZyklusKlar does not require an account or operate a server collecting your health records. If you share reports or backups, you choose where they go.
Can I use the app for contraception?
No. Cycle estimates do not confirm fertile or infertile days. ZyklusKlar is not a contraceptive method and does not replace medical advice.
What does the pause feature do?
You can mark a day without bleeding during an ongoing period as a pause. The period stays open. You decide when to mark its start and end, and you can correct your entries.
What is the PDF report for?
It summarises your recorded bleeding, symptoms and history. You can print it and take it to a medical appointment. It contains your records, not a diagnosis.
Which devices and languages are planned?
The initial release is planned for Android. An English-language app version is also planned; the screenshots currently show the German interface. A confirmed Google Play link will be added once the app is published there.
