100% Free · No account or email · Stays on your device · Works offline

Know your cycle, without handing your private life to a company.

Most period apps ask for your email, store your intimate notes in the cloud, and lock basic charts behind a paywall. Vernya is different: it opens right on your phone or computer, remembers your rhythm, and keeps every single entry on your device.

Takes 10 seconds · No sign-up, no app store, no ads, ever.

Period tracking, trying for a baby, pregnancy & perimenopause

Built for real life

Everything you need to understand your body. Nothing you don't.

No pop-ups, no pink-tax subscriptions, and no confusing medical jargon. Just a calm, reliable place to keep track of your days.

Privacy you can verify

Stays on your phone, locked like a diary

Your history stays inside your browser on your device. Want extra peace of mind on a shared phone? Turn on a 4–6 digit PIN lock, or switch on Stealth Mode to hide the Vernya name and icon on your home screen.

Doctor-ready history

Walk into your next check-up with real answers

Stop scrolling frantically through your calendar in the waiting room. Download a clean, one-page PDF report or spreadsheet showing your exact start dates, how many days bleeding lasted, and how much your cycle varies.

Clear patterns

Spot why you feel the way you do

Log flow, cramps, headaches, sleep, morning temperature, and mood in a few taps. After a couple of months, Vernya's simple charts show which days you usually feel tired, anxious, or full of energy—so you can plan your week around your body.

Share on your terms

Keep a partner in the loop—without sharing your diary

Want your partner to know when your period or fertile days are coming up? Create a password-locked, read-only snapshot link. They see the dates that matter, while your personal notes stay completely private.

Gentle health heads-up

Notices when something is worth asking a doctor about

If your cycle runs past 45 days, jumps around by more than two weeks, or has several heavy-flow days in a row, Vernya gives you a calm, plain-English heads-up—never a scary diagnosis.

Adapts to your chapter

One app for every stage of your cycle

Switch modes anytime in two taps. Your past history stays safe whenever your goals change.

Everyday rhythm

Just tracking my period

Know when your next period is expected, how long bleeding usually lasts for you, and which days PMS tends to show up—so you're never caught off guard.

Trying to conceive

Trying for a baby

Highlights your 6 most fertile days each month. Combine your cycle dates with morning temperature and natural body signs to confirm when you ovulate.

Week by week

Following a pregnancy

Pauses period predictions and counts how many weeks and days along you are, how many days until your due date, and how you're feeling day by day.

Changing cycles

Perimenopause & menopause

Made for cycles that are getting longer, shorter, or skipping months. Track how much your dates shift along with sleep, mood, and body changes without broken alerts.

Honest comparison

How Vernya compares to typical period apps

Questions & answers

Common questions, answered in plain English

Everything you might wonder about privacy, accuracy, doctors' visits, and switching phones.

Where is my period data actually stored?

Right on the phone, tablet, or computer you're using. Vernya saves your entries inside your browser's local storage on your device. We don't have a giant database of users' cycles, so we can't see, sell, or leak your personal history.

Do I need to create an account or give my email?

No. You never have to enter an email address, phone number, or real name. Just open Vernya, pick any nickname you like, and log your first date.

What happens if I get a new phone or clear my browser?

Because your data lives on your device, clearing your browser storage or losing your phone would erase it—unless you save a backup. From Settings, you can download a password-locked backup file in two taps and restore it on your new phone anytime. We also offer optional end-to-end encrypted sync if you use multiple devices daily.

Can I use Vernya without an internet connection?

Yes. Once you've opened Vernya once, logging periods, checking your calendar, viewing charts, and reading the cycle guides all work offline—even on a plane or in areas with no signal.

How do I share my cycle history with my doctor or nurse?

Go to Cycle History or Trends and tap 'Download PDF' or 'Printable report'. Vernya creates a clean, easy-to-read summary of your period dates, cycle lengths, and notes that you can print out or show on your screen during your appointment.

Can I track irregular cycles, pregnancy, or perimenopause?

Yes. You can switch between four modes anytime: regular Cycle Tracking, Trying to Conceive (which highlights fertile days and morning temperature), Pregnancy (which tracks weeks along and your due date), and Perimenopause / Menopause (which tracks how much your cycle length shifts without assuming a 28-day clock).

How do the optional smart summaries work with my privacy?

Smart summaries are turned off by default. If you choose to turn them on in Profile Settings, Vernya only sends anonymous cycle numbers and dates (never your name, birth year, or written notes) to generate a short reading. You can turn it back off anytime.

Is Vernya a medical device or a form of birth control?

No. Vernya is a personal wellness and cycle-tracking tool to help you understand your own patterns. It cannot diagnose medical conditions and should not be used as contraception to prevent pregnancy. Always talk to a doctor or nurse about medical questions.
