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.
Built for real life
No pop-ups, no pink-tax subscriptions, and no confusing medical jargon. Just a calm, reliable place to keep track of your days.
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.
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.
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.
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.
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
Switch modes anytime in two taps. Your past history stays safe whenever your goals change.
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.
Highlights your 6 most fertile days each month. Combine your cycle dates with morning temperature and natural body signs to confirm when you ovulate.
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.
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
Most free period trackers make money from your personal health profile or push you into a monthly subscription. Here is how Vernya does things differently.
| What matters to you | Vernya | Typical period apps |
|---|---|---|
| Account, email, or phone number required | Never — open and start right away | Requires sign-up and personal onboarding quiz |
| Where your cycle history and notes live | On your device only (plus backups you control) | Stored on company cloud servers |
| Ads, pop-ups, or selling health data | Zero ads, zero tracking, zero data brokers | Often funded by targeted ads or upsells |
| Printable PDF & CSV report for your doctor | Free and built right in | Usually locked behind a paid subscription |
| Works on a plane or without internet | Yes — logging, charts, and guides work offline | Often fails to load without a connection |
| Optional smart summaries | Off by default; never sends your name or notes | Always-on cloud processing |
Zero friction
Nothing to download from an app store, and no account form to fill out.
Works on any iPhone, Android, tablet, or computer. Add it to your home screen if you want it to open just like a regular app.
Choose whether you're tracking periods, trying to conceive, pregnant, or in perimenopause. Add a 4–6 digit PIN if you want extra privacy.
Mark when bleeding starts or ends, jot down how you feel, and download a password-locked backup file whenever you switch phones.
Plain-English library
Built right into Vernya so you can read them offline anytime. Written in everyday language, not textbook jargon.
Your cycle moves through four phases each month. Knowing what each one does helps explain how you feel.
Your fertile days are about six days long, ending the day you ovulate. A few simple signs can help you spot them.
Some patterns are worth a chat with a health professional. None of these on their own mean something is wrong.
Hormone changes affect mood. Tracking helps you see your own pattern, without judgment.
Your morning temperature can confirm that you ovulated—useful if you're trying to conceive or want to understand your cycle.
How Vernya keeps your tracking on your device, and what that means in plain language.
Questions & answers
Everything you might wonder about privacy, accuracy, doctors' visits, and switching phones.
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.
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.
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.
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.
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.
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).
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.
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.
