Vyana: Private Period Tracker

Built after the big trackers were fined for selling cycle data. Vyana has no ads, no data sales, no tracking and it never calls your cycle "late".

Vyana is your private cycle companion, built for real cycles, including irregular ones.

No ads. No selling your data. No cross-app tracking. And you can delete everything, anytime, directly from the app.

If your cycle is 27 days one month and 42 the next, Vyana doesn’t call you “late” just because you don’t fit a textbook pattern. It shows your actual cycle range, separates what it knows from what it’s estimating, and gets smarter about your personal rhythm as you log.

With Vyana, you get:

• Honest predictions — predictions based on your own cycle history, with uncertainty where it matters. • Personal insights — understand patterns in your cycle, symptoms, and logs over time. • Gentle daily check-ins — quickly log how you’re feeling without turning tracking into a chore. • Ask-anything guidance — get clear, useful answers with sources you can explore. • Partner mode, on your terms — share what you choose, when you choose. • Privacy by design — no ads, no data sales, no cross-app tracking, and full control over your data.

Your cycle isn't a calendar. It's yours.

Vyana is designed for wellness and education and is not a substitute for professional medical advice, diagnosis, or treatment. If you have concerns about your health or cycle, consult a qualified healthcare professional.
